I just ordered the M18 Fuel 3/8 drive tonight, and I bought an M12 1/2" Stubby last week. I was doing the brakes all the way around on my wife's truck last weekend and my M18 1/2" high torque was to long to get on one of the front brake brackets and both the the rear brake bracket bolts so I got the 1/2" M12 stubby. It removed the lugnuts on my truck (torqued to 130 ft lbs) with no problem....for a 12v, no problem. I'm really shocked, like you, that the 3/8 outperformed the 1/2". Someone else commented that the adapter had something to do with it, however, when I watched your side by side between the Milwaukee, the Dewalt and the Snap-on, I remember you saying that the adapter is welded to the socket....therefore the adapter should be out of the equation and not have any influence on the testing because being welded it's now a solid part of the socket. Where with me, I wouldn't weld on my adapter so I can use my socket on either the 1/2" or the 3/8 adapted, so I would have movement between the adapter and the socket. Love your channel and the reviews. Just a quick thought...and this isnt to get an argument started. Just an observation and opinion... Why would you (people in general) want to spend their hard earned dollars on the overrated, underperforming tools of S-O??? Status symbol??? "All my tools are S-O. I've got over $50,000 wrapped up in tools in my $25,000 toolbox." WHY??? All you're buying is the name. I just don't see it. My dad always told me, a fool and his money soon part.
Upgraded from an older 18v kit. th-cam.com/users/postUgkxW1vOBRCMrgTCDEijzpVzDWsgI-Jm2iQv I independently chose the drill and impact tool, before I came across the kit.I like the 3 speed impact gun. It seems more powerful than my older one, and it can be set to be really gentle. The drill is more appropriately sized for my use. I used to have a hammer drill, but I did not like that it was so big and it was not a great hammer drill. I rather have a smaller drill like this, and then get a corded hammer drill for the odd case I need that.
i think the reason the 3/8 did better than the 1/2 is because the adaptor is welded so it does not lose power like an adaptor would so the added mass of the adaptor actually works like a weighted socket which adds power
@DirectCurrent4u but the adapter was used on the 3/8 not the 1/2 and the 3/8 outperformed the 1/2" If the the adapter causes less torque, what you said isn't logical.
Since its welded, It would be no different than connecting the socket directly to the anvil. Those 4, 5, 6 ounces aren't going to make a difference in the torque.
If the adapter is welded to the socket then it's no longer an adapter it's part of the socket and for it's a super heavy socket which causes more force
I know it would be expensive but I’d love to see this same exact test done again with two new impacts to see if by chance something was indeed wrong with that 1/2 in or if something was extra with that 3/8 in.
There are multiple types of torque in the tools. I own the mid torque 1/2" 550ftlbs I believe it's rated for. I don't think that this is a good representation of the two. If these are both a low torque wrench then I don't think it matters which size you get. Choose the torque size tool for your needs. Plus, I dont think they even make a high torque 3/8".
There is nothing like Milwaukee impacts. I like dewalt drills and stuff but for impacts Milwaukee is the best no doubt about it. Great vids bro. Can’t wait to get my hands on one of those
Makitas mid torque has 90ftlbs more torque and multiple features none of the milwuakee does. Stop being a fanboy and buy tools according to your needs not marketing. Btw I own milwuakee super sawzall

Looks like you might be the fanboy. 1/2 lag bolt trough 4x4's, Makita max torque 348, stops on the second 4x4, Milwaukee 468 drives it flush, drives it so fast it smokes the wood. LOL, Makita's are ok...
Torque test channel did a very indepth test of anvil sizes and torque output, even with a custom made socket that weighted a considerable amount it performed worse than the standard socket you'd use with a 3/8" or 1/2", a larger anvil has more mass which requires more kinetic energy to drive it, while 1/2 is not that much larger than 3/8 its still a sizable difference that produces different results. It's very interesting to see other real world results showing the capabilities of both drives, I've just recently purchased my first impact wrench and its the 2854 and i'm glad to see the 2855 doesn't stomp all over it as for my needs i dont need more than 200ft lbs of breakaway torque. For hobbyist needs the 3/8 is perfect the compact size makes it handy for tighter spaces, but from every mechanic and tech i've heard from they do still have a 1/2" ready if they need the extra power, with that being said though you can stick a much larger battery on your tool and increase the power output quite considerably.
Great detailed video. I personally would've loved to see a non-welded adaptor so we are comparing with the exact same 1/2" socket across both units. Nonetheless this is great to show the potential of what a 3/8 can provide. Thanks
I may be wrong, but as near as I can tell, the tools are identical aside from the anvil, anvil washer, and front housing. In order to swap the anvil, you must swap the other two parts and you end up with something identical to the other tool aside from the sticker.
If I had to guess, the reduced weight of the 3/8” anvil allows for more energy to be transferred in the “removal” forces rather than energy wasted in turning the heavier anvil. I imagine this as if you had two Honda civics and one had its interior gutted. The gutted civic is going to perform better due to the lower weight. The crazy thing is how much a half an ounce can change their output.
In theory, with the same motors using the same gearpack, they should function essentially identically when allowing for unit to unit variance. My personal preference is to use 1/2" anvils for all my impacts.
Very odd result! I've compared my M18 1/2" And 3/4" Impact wrenches and if using an 3/4 to 1/2" adapter on the bigger gun, it failed to loosen stuff that the 1/2" wrench had no problem with and that's considering the 3/4 version is considerably more powerful. Then to be more conclusive When used the 3/4 impact with a 3/4" socket, and the 1/2 impact with a 1/3 socket but both for the same size fasteners, the 3/4 impact was much better. Will be interesting to see what Milwaukee has to say or even if tried another pair of guns to see was there anything different or not right with these two. Good review and interesting result 😎
The welded 3/8 socket actually helped the 3/8 add more weight to the fastener. The more weight you apply to a fastener, the easier it is for the impact wrench to break it. 1/2 to 3/8 welded socket and the 1/2 FUEL would have won. However, an adapter that isn't welded (even worse a woble) causes a reduction
Garbage. Your statement breaks the laws of physics. If anything the greater mass of the heavier socket/adapter should have absorbed more energy and therefore produced less torque. What are the physics behind your assertion? There were so many variables involved that it would take a far more detailed test to discover the discrepancies. It is possible that the 3/8 driver had a more powerful battery as not all batteries coming from the factory are identical despite their labelling. It is possible that it was just more powerful because of some difference in the software or hardware, two identical models of cars from the same factory can have different 0-100 times for example.
The reason why the 3/8" is outperforming the 1/2" is because the adapter in this case is adding weight which helps on each impact. USUALLY, adapters tend to lose torque but if the adapter is made to tight tolerances with very little play, the weight added to each impact can more than make up for it.
I’d buy the 3/8 for sure. I can use it with swivel 3/8 impact sockets which fits great in tight places. I’d buy 1/2 inch mid torque if i need more power and light weight
Went to a shop here in Taiwan (where they do the manufacturing for these tools) and found they had a dizzying number of different models, probably 30 different models just within the impact and standard drivers. There were about 8 impact drivers all similar in appearance but no idea which one is which one. The store staff was not familiar with it. Ended up just buying a cool Milwaukee hammer and leaving it at that.
@@oakleyjohnson6792 Check torque test channel, they proved it doesnt matter. Its not the number of connection points that cause the most loss, its the distance of material the force have to travel through (from anvil to work piece). 3x5" extensions have the same loss as 1x15"
I've watched multiple videos of exactly that. The additional weight makes more impact power. Watched one, that had a really heavy weight added and made a huge diff.
Added weight, huh... if it were the other way around, people would still claim the adapter is causing the lack of torque. Great video! I’ll still be going with the 3/8”. My high torque can be my only 1/2” for a good while.
Just like a Lisle 19mm Socket for them infamous Honda Crank bolts real world use the 3/8 has a longer heavier socket plus its welded no play to bleed off torque so more mass/power. There's your answer👍 BTW I own both my results all being equal "same size socket" no adapter the 1/2 will take a fastener off faster, once you add adapter to the 3/8 it's the other way around normally anything past 3/8 24mm socket that little bit of mass makes a difference.
After viewing this video I purchased the set including 2 5 amp batteries! Downside of watching a lot of youtube, but I really need tools that increase my home DIY capabilities. I will probably order one of the mid torque guns as well in either the 3/8 or 1/2 inch flavors.
This would have been a better comparison if you had the same 1/2 socket that was welded to the 3/8 adapter used on the 1/2 impact. You can clearly see that the socket is much larger in the 3/8 set up compared to the 1/2 socket used in the 1/2 impact. That and the adapter having more mass would give you the 25-30% increase in loosening torque.
I got the 3/8 a couple months ago. For working on cars at home, it's great. Nothing has stopped it. Put a good quality 3/8 to 1/2 adapter (NOT HARBOR FREIGHT!!) on it and have at it.
I see many comments talking about the 3/8 to 1/2 adapter...do you find yourself using the adapter often? If so do you wish you would have just got the 1/2 compact m18 impact?
@@user-dy2xu3uv8k It's hard to say, but after using it a while, I think I would go with the 1/2 inch model. Sometimes space is so tight that I figured I didn't want to chance the girth of 1/2 inch drive extensions and swivels. It's so powerful that I don't think a quality adapter causes it to lose much torque.
I believe it has to do with rotations per minute. The 3/8 anvil rotates more per minute than the 1/2, I’m Just guessing I could be wrong. That’s the only reason I can think of.
kinetic energy = 0.5 × mass × speed The kinetic energy of the 3/8” is clearly higher than the 1/2”. You could verify that if you wish ( probably not worth dismantling either to weigh the anvils for this rough calculation. Weigh the 1/2” socket & the combined 3/8” adapter and socket. A hand held rev counter would give you rpm which would then be converted in velocity. The above formula then provides their kinetic energy. It has to be the socket/adapter weight difference as opposed to any difference in rpm/velocity. Enquiring minds need to know (for sure.)
Look at the length of the socket on the 3/8 (much longer 16:34)....extra mass made the difference, especially with the socket adapter welded on adding more mass.
I debated back and forth between getting a 1/2” and a 3/8” compact for a few months and ended up getting a 1/2”. I plan on getting almost all the Milwaukee impact wrenches anyway 🤷🏾♂️
Try and find a 1/2 in drive 33mm with about the same mass as that one with the adapter and the results will probably equal out. But the results do seem to say a 3/8 with an adapter could break more then a straight 1/2in drive
I see this a lot with videos using adapters. My theory is the running start. An impact is basically a sideways hammer function. On the 1/2” drive that socket is tight, like putting a hammer on a nail then hitting it. On the 3/8” that adapter adds slop, hold the hammer off the nail then striking it. You can see in the video the 3/8” vibrates a lot more, like it’s getting a running start with every impact. Like getting 2 strikes for the price of 1.
The 3/8" should, on the same size bolt, in theory, should be able to deliver slightly more energy to the bolt, since the 3/8" anvil and socket will have slightly less mass, which means less inertia to overcome. The way I figure, get the 3/8 for compact and mid-impact wrenches, and get the 1/2 for high-impact applications. Why haul around more mass if you don't need to?
I would like to see the test without the 1/2 adapter to 3/8 or put an extension on the 1/2 to be the same. Most of the time if you just need a little more power you can add an adapter to help the impact loosen a nut. It helps the impact break the nuts free with that little extra space between the socket and the impact.
Odd. My 1/2” stubby will generally remove something my 3/8” cannot. I’ve done this on vehicles alot and usually the 1/2” is always the one that gets it done.
A man that knows his physics! This is all due to the weight of the socket. It's Speed x's Mass = Force. When you cannot remove something with a small socket, get a bigger socket and the impact wrench will remove it. You don't have to pay for the 1/2, you can buy the 3/8 and just buy larger sockets.
Can you please do the same video but with the Milwaukee 3/8 and 1/2 mid torque impacts? I understand there's a 50 ft-lbs out put difference but I'm very curious about the results.
The adapter adds weight and will increase the hammer force of each impact. Noticed it first time on Detroit Diesel engines main bearing bolts. They are tightened to around like 600 foot pounds it’s a torque to yield bolt so not sure the full torque but the big 1/2 Milwaukee would only break those loose if I used a 1/2 to 3/4 adapter if you used a strait half inch socket it wouldn’t break them loose. But was still super impressed it could break those bolts loose it’s no joke trying to torque them
Great video! Can you make a video comparing the 3/8 with the welded adapter and with a normal adapter that's not welded. Does the welded adapter provide any advatage that will not be experienced under normal circumstances with a regular adapter?
I would be curious your testing difference between the Milwaukee XC5.0 vs HO6.0 as the 5ah uses 18650 cells (20A per cell) while the 6Ah uses the 21700 (25A per cell) which are 25% higher output. Keep up the great work!
Maybe the slop is helping improve the hammering force kindof like how if you can’t pull someone out of the ditch with the strap tight you put slip in the slack in jerk on it and you get it
Glad I got the 3/8 mid and the 1/2 high. But I would like to see if you can get the batteries to fall off. I hear about this from alot of techs. I am a diy'er and don't use as often as a tech.
We have not had issues with batteries falling off our M18 tools. I know that M12 batteries can break the tabs when used a lot, but not so much the m18. Thanks for watching.
Can I ask why you use such a big socket? 33mm on half in is about as big as you’d go. And why not just use a size that is compatible with 3/8 and 1/2 inch? Wouldn’t that be a more comparable test?
In order to test these impacts, we have to torque these nuts/bolts to 500 ft-lbs. Even these large fasteners are reaching their point of failure at this point. Anything smaller would definitely fail. They don't make a 33mm socket in 3/8". Thanks for watching.
@@Shoptoolreviews yeah put that way it makes perfect sense I obviously didn’t take into consideration the amount of torque needed to test these guns now. Keep up the good work!
Love the mid torque - it's a beast. The impact driver with whatever anvil you want on it does 200 ft lbs. Wish I could have one of everything but I'd rather have an impact wrench with similar specs. I guess if you put a 3/8 anvil it will be even stronger than the 1/2 I've been using:)
Im planning to get one of these tmrw new in box for 120$. I’m going with the 3/8 model. Seems like well enough power for what I need and I have a lot more 3/8” sockets than 1/2”.
Having the adapter may very well provide twice the impact. During each impact the adapter is struck first followed by the socket. The torque is released and repeated each impact. Both impacts (adapter and socket) affect the fastener leading to twice the number of impacts.
You lose torque with longer extensions. You can find this out by using an impact with and without an extension and find yourself loosening much slower with the extension added.
I just bought that half inch torque Driver…. I don’t get too crazy on the specs and what not but I know that every time I use it under the hood of my car‘s and for any other rusted bolt it has perform Great…. So I am happy with my purchase… but great video it’s always good to see how they perform against each other… thanks..
By the looks of it in your thumbnail the 3/8 impact looks to have a longer heavier socket which if you watch mrsubaru’s video he has shown the difference between lighter and heavier impact sockets. I’m not saying it’s all from just the socket but that would help it slightly
@@Shoptoolreviews the mass difference between sockets makes a substantial difference. It's physics. Objects in motion want to stay in motion. [F]orce = [m]ass[a]cceleration ; F=ma
Went out and bought a 3/8 this week and I saw there's the same thing in 1/2. About capped my pants but after seeing these videos I'm happy with my purchase again
2855 is a lemon! By any chance, is there a theoretical number or range of numbers should we fasten a m14 x 1.5 lug nuts for 2 full seconds? I was wondering if I can get to the 100 ft/lbs mark in 2 full seconds run. Thanks for the great content.
Are these compact wrenches worth buying if you have the Mid-Torque 2962 1/2 Impact Wrench? All I see is it's 1 inch less in length and 1 pound less in weight. I don't think it really is.
sometimes the sockets matter, for instance i was trying to take out a bolt using a matco mid-length impact socket, the bolt would not budge, switched to a snap on deep impact socket on the same gun, took it off the bolt in 6 seconds. The snap on impact socket had a much thicker side wall. maybe the difference in socket affected the results? u switched out the battery, but kept the same socket.
So i got the 3/8 version with a 3.0 battery and i just love it. It was a tuff choice over the stubby by im glad i got it. Rated at 250 ft lbs but i swear it has a little more kick than the M12 stubby. It also feels great in my hand. I can get to all kinds of tight places. Yes there might be a tight spot that the subby my fit better but for me its kinda rare and im never afaraid to grab a wrench. Conclusion: I really love the 3/8 M18 AND 3.0 BATTERY. Yes, it struggles with larger tuffer bolts but thats what my 2967 is for.
I say go with the size that best matches the drive size of sockets you use so you’re not adding length with an adapter. I believe the difference in performance between these two are just normal manufacturing variation.
@10:11 you see clearly why there’s a difference. In performance just by looking at the sockets side by side. So you basically demonstrated how heavy sockets work. Get an half in dr socket to the one with the 3/8 dr one and re test. Also you could weigh both sockets, and I bet the percentage difference in weight, will correlate almost exactly to the average percentage difference in our put.
I think the 1/2 inch isnt broken in yet vs the well seasond 3/8 impact after you put some miles on the 1/2" I think we should revisit this review 😉? I own these tools and have a question is there a break in period for the motors planetary gears anvils and so forth so my question from out the box is there a period of break in I will contact milwaukee and ask these questions unless you already have the answers please get back with me on this thanks brother have a wonderful day
I have a question on Ryobi brand. I started with them 8-10 years ago, whenever they came out with the 20” mower & weed trimmer in the 40v. I have since been using their 18v (One+) tools as well. I have to take apart their battery packs (mainly on the 18v) to repair them when they fall below voltage where the BMS turns off the battery. Anyway, I was wondering if you had a comment on the Ryobi for quality? I do know there are DeWalt battery problems as well as Ryobi (I don’t have any experience with Milwaukee but since the same TTI owner owns most of those I would asssume they use similarly battery technology. Thanks again for your videos. I have seen several of your videos with the same metal plate with those nuts on that metal plate. Good job!
Genial!!! Ahora voy ppr Llave de impacto 2854-20 de 3/8.. las pruebas demostraron su capacidad de fuerza aunque con características similares Ya tienes la demostración de la llave de impacto de 2962P-20 ????
How high can the grey torque impact with the arm go? use one that we have to tow a compressor around id like to look it up save alot of Hassel if we could just get a few batterys instead of towing
TIM from Canada to answer your question which one would I use it would depend on what jobs I am using it for.. if basically I am only using 3/8 sockets then the 3/8 drill would be the one. If I was an automotive and I was using half-inch then the half-inch would be the one.. it depends on what job you are using it for if your work only deals with 3/8’s then that’s the one if your job only work with 1/2”inch then this is the one as I said before it has to deal with your job and what you were using it for
The only way to determine anything is to get another 1/2 and 3/8 impact and repeat the test. People keep suggesting that the extra weight of the adapter was the difference. The couple of ounces, located as close to the center point as possible would never cause 150ftlbs difference in performance.
It seems like the 3/8" socket is different from the 1/2" drive socket. The 3/8" drive socket with the adapter is heavier and harder than the 1/2" drive socket. The material CrMo socket is better than the CrV socket. CrMo socket has higher momentum and harmonic than CrV socket.
You should’ve tried it with the same socket. The adapter probably didn’t add much weight. But that bigger one looks like an axle nut socket, they’re heavier than a standard socket.
Before watching, my guess is because the heavier socket maintains and compacts moment as it impacts. Welp nevermind lol, I guess you're using the same socket. Oh hey, so the 3/8" made more power? Maybe the additional weight of the adapter helped a little.
What Gen is the 2854 in the video? 2 or 3? Home Depot is selling Gen's 2 and 3 of the same model. I need the one that's in the video. For all I know they could've nerfed the Gen 3!
I still use my ole Ingersoll rand 231c 1/2 inch air gun , one I've had for 40 years , they break anything loose that I've ran into , except semi lug nuts , yeah sometimes it will break them loose , but never try tightening them and sending it without a torque wrench , nope standing on a long bar ..no good either ....gotta have the expensive 1300 ft lb torque wrench , ask me how I know..😁 I lost some semi duals a couple times trying it out ..
So if the Milwaukee 3/8 does 500 ft-lbs does it beat the new DeWalt Atomic 3/8 impact wrench since the Dewalt Atomic 1/2 only does 450 ft-lbs??? It seems in the reviews on Home Depot the new Dewalt Atomic 3/8 impact wrench is not getting as good reviews as the 1/2 model....
What was the combined mass of the adapter and socket used with the 3/8" drive vs. the mass of just the socket used with the 1/2" drive? If you used a deeper socket on the 1/2" drive to make the differences in mass more equal, I wonder if the results would change.
i know they say heavier sockets are better but ive on multiple occasions raddled on a lug nut with a deep impact socket to no avail then threw on the shallow socket from the same set and right away it undid it
The adapter mass definitely plays a part in torque....I always have more power with more weight in the socket. Also not all impacts perform the same....it's like an engine produced, some engines have more power than another of the same engine on the dyno. I bought a mid torque Makita rated at 740 ft/lbs nut busting and my M12 Milwaukee 1/2" stubby out performed it! Obviously I think something was wrong with the Makita but it worked and sounded normal, but I returned it cause it was useless to me.

Torque test channel did a very indepth test of anvil sizes and torque output, even with a custom made socket that weighted a considerable amount it performed worse than the standard socket you'd use with a 3/8" or 1/2", a larger anvil has more mass which requires more kinetic energy to drive it, while 1/2 is not that much larger than 3/8 its still a sizable difference that produces different results.
It's very interesting to see other real world results showing the capabilities of both drives, I've just recently purchased my first impact wrench and its the 2854 and i'm glad to see the 2855 doesn't stomp all over it as for my needs i dont need more than 200ft lbs of breakaway torque.
For hobbyist needs the 3/8 is perfect the compact size makes it handy for tighter spaces, but from every mechanic and tech i've heard from they do still have a 1/2" ready if they need the extra power, with that being said though you can stick a much larger battery on your tool and increase the power output quite considerably.
Great detailed video. I personally would've loved to see a non-welded adaptor so we are comparing with the exact same 1/2" socket across both units. Nonetheless this is great to show the potential of what a 3/8 can provide. Thanks
As always, very thorough review, thanks for all you do
Glad you like them! Thanks for watching.
Open them up and switch the anvils. After that I would say it would be the extra weight of the 3/8” socket and adaptor.
We will probably do this but at another time. Thanks for watching.
I may be wrong, but as near as I can tell, the tools are identical aside from the anvil, anvil washer, and front housing. In order to swap the anvil, you must swap the other two parts and you end up with something identical to the other tool aside from the sticker.
If I had to guess, the reduced weight of the 3/8” anvil allows for more energy to be transferred in the “removal” forces rather than energy wasted in turning the heavier anvil. I imagine this as if you had two Honda civics and one had its interior gutted. The gutted civic is going to perform better due to the lower weight. The crazy thing is how much a half an ounce can change their output.
@@enchantedwenis4994 i wonder if this the same for the m18 fuel mid torque
Maybe one made in China other in Mexico o Taiwan
In theory, with the same motors using the same gearpack, they should function essentially identically when allowing for unit to unit variance. My personal preference is to use 1/2" anvils for all my impacts.
I love my M12. Not much it can't handle. Just replaced my entire steering kit using one. Tie rod ends don't come out easy.
Very odd result! I've compared my M18 1/2" And 3/4" Impact wrenches and if using an 3/4 to 1/2" adapter on the bigger gun, it failed to loosen stuff that the 1/2" wrench had no problem with and that's considering the 3/4 version is considerably more powerful.
Then to be more conclusive When used the 3/4 impact with a 3/4" socket, and the 1/2 impact with a 1/3 socket but both for the same size fasteners, the 3/4 impact was much better.
Will be interesting to see what Milwaukee has to say or even if tried another pair of guns to see was there anything different or not right with these two.
Good review and interesting result 😎
I own the 3/8 gen 3 compact impact it’s a beast I use it for wheel lugs all the time at work I’m about to buy the m12 right angle impact maybe today
is the right angle m12 worth it because I'm looking to start my tool collection
The welded 3/8 socket actually helped the 3/8 add more weight to the fastener. The more weight you apply to a fastener, the easier it is for the impact wrench to break it. 1/2 to 3/8 welded socket and the 1/2 FUEL would have won. However, an adapter that isn't welded (even worse a woble) causes a reduction
Garbage. Your statement breaks the laws of physics. If anything the greater mass of the heavier socket/adapter should have absorbed more energy and therefore produced less torque. What are the physics behind your assertion? There were so many variables involved that it would take a far more detailed test to discover the discrepancies. It is possible that the 3/8 driver had a more powerful battery as not all batteries coming from the factory are identical despite their labelling. It is possible that it was just more powerful because of some difference in the software or hardware, two identical models of cars from the same factory can have different 0-100 times for example.
correct
I've heard this before. More mass added on the socket helps. That adapter definitely helped the 3/8
@@teeanahera8949 not garbage not absorbing energy but creating it. Proven many times. The reason weighted sockets (especially for Honda cranks) exist.
The reason why the 3/8" is outperforming the 1/2" is because the adapter in this case is adding weight which helps on each impact. USUALLY, adapters tend to lose torque but if the adapter is made to tight tolerances with very little play, the weight added to each impact can more than make up for it.
I’d buy the 3/8 for sure. I can use it with swivel 3/8 impact sockets which fits great in tight places. I’d buy 1/2 inch mid torque if i need more power and light weight
Right on, that's the way to do it. Thanks for watching.
What gen is in this video?
How about using a 1/2" to 3/4 and see if with the added weight the 1/2 wins with the 3/8 using the same setup
Went to a shop here in Taiwan (where they do the manufacturing for these tools) and found they had a dizzying number of different models, probably 30 different models just within the impact and standard drivers.
There were about 8 impact drivers all similar in appearance but no idea which one is which one.
The store staff was not familiar with it.
Ended up just buying a cool Milwaukee hammer and leaving it at that.
Models vary between US and international Milwaukee stuff. We have different models.
It's got to be the mass of the half inch adapter on the 3/8 impact wrench that is making the difference plus the weight of the weld
I guess I need to run 1/2” adapters for more power.
@@runningproblem Adapters will lose more power than you gain from weight / surface contact
@@kvernesdotten not when it’s welded it makes it one sold piece
@@oakleyjohnson6792 Check torque test channel, they proved it doesnt matter. Its not the number of connection points that cause the most loss, its the distance of material the force have to travel through (from anvil to work piece). 3x5" extensions have the same loss as 1x15"
I've watched multiple videos of exactly that. The additional weight makes more impact power. Watched one, that had a really heavy weight added and made a huge diff.
Added weight, huh... if it were the other way around, people would still claim the adapter is causing the lack of torque. Great video! I’ll still be going with the 3/8”. My high torque can be my only 1/2” for a good while.
You are correct. Not a bad idea going with the 3/8", makes sense when you have the High Torque. Thanks for watching.
Added weight of the socket and adapter = added torque in an impact
Just like a Lisle 19mm Socket for them infamous Honda Crank bolts real world use the 3/8 has a longer heavier socket plus its welded no play to bleed off torque so more mass/power. There's your answer👍 BTW I own both my results all being equal "same size socket" no adapter the 1/2 will take a fastener off faster, once you add adapter to the 3/8 it's the other way around normally anything past 3/8 24mm socket that little bit of mass makes a difference.
My problem with the 3/8 is that it’s friction ring only. I would love it more if it was pin detention.
After viewing this video I purchased the set including 2 5 amp batteries! Downside of watching a lot of youtube, but I really need tools that increase my home DIY capabilities. I will probably order one of the mid torque guns as well in either the 3/8 or 1/2 inch flavors.
The reason is because you solder a 3/8 adapter to 1/2 socket, it's make more mass. Heavier your sockets more power you get.
I'm pretty sure he didn't solder it
Yes he did weld the adapter to the socket.th-cam.com/video/-zoNy5s_lhs/w-d-xo.html
@@nexus5482 he is meaning that he welded it, not soldered it.
This would have been a better comparison if you had the same 1/2 socket that was welded to the 3/8 adapter used on the 1/2 impact. You can clearly see that the socket is much larger in the 3/8 set up compared to the 1/2 socket used in the 1/2 impact. That and the adapter having more mass would give you the 25-30% increase in loosening torque.
Wow! On subcompact platforms no less. Can't figure that 3/8 though.😁 Great video tim!
You and me both! Thanks.
why i didn't find this video before i bought the 1/2 impact 🥺🥺😔🥺🥺
Lol. You're still fine, I'm sure. Both of these are great impacts. Thanks for watching.
I got the 3/8 a couple months ago. For working on cars at home, it's great. Nothing has stopped it. Put a good quality 3/8 to 1/2 adapter (NOT HARBOR FREIGHT!!) on it and have at it.
I see many comments talking about the 3/8 to 1/2 adapter...do you find yourself using the adapter often? If so do you wish you would have just got the 1/2 compact m18 impact?
@@user-dy2xu3uv8k It's hard to say, but after using it a while, I think I would go with the 1/2 inch model. Sometimes space is so tight that I figured I didn't want to chance the girth of 1/2 inch drive extensions and swivels. It's so powerful that I don't think a quality adapter causes it to lose much torque.
Check out Torque Test Channel. They have some great testing going on there.
I believe it has to do with rotations per minute. The 3/8 anvil rotates more per minute than the 1/2, I’m Just guessing I could be wrong. That’s the only reason I can think of.
kinetic energy = 0.5 × mass × speed
The kinetic energy of the 3/8” is clearly higher than the 1/2”.
You could verify that if you wish ( probably not worth dismantling either to weigh the anvils for this rough calculation.
Weigh the 1/2” socket & the combined 3/8” adapter and socket.
A hand held rev counter would give you rpm which would then be converted in velocity.
The above formula then provides their kinetic energy.
It has to be the socket/adapter weight difference as opposed to any difference in rpm/velocity.
Enquiring minds need to know (for sure.)
Look at the length of the socket on the 3/8 (much longer 16:34)....extra mass made the difference, especially with the socket adapter welded on adding more mass.
I debated back and forth between getting a 1/2” and a 3/8” compact for a few months and ended up getting a 1/2”. I plan on getting almost all the Milwaukee impact wrenches anyway 🤷🏾♂️
They're great impacts, and even this 1/2" compact is a great tool. Thanks for watching.
@@Shoptoolreviews Would be curious if the Gen 2 Mid-Torque ends up the same way in the 3/8 outperforming the 1/2. Maybe the next test?
I'm very underwhelmed by my 2855. Especially considering I paid $220 when I could've gotten the mid torque for $170.
Try and find a 1/2 in drive 33mm with about the same mass as that one with the adapter and the results will probably equal out. But the results do seem to say a 3/8 with an adapter could break more then a straight 1/2in drive
Thanks for this! Im going for the 3/8!
I see this a lot with videos using adapters. My theory is the running start. An impact is basically a sideways hammer function. On the 1/2” drive that socket is tight, like putting a hammer on a nail then hitting it. On the 3/8” that adapter adds slop, hold the hammer off the nail then striking it. You can see in the video the 3/8” vibrates a lot more, like it’s getting a running start with every impact. Like getting 2 strikes for the price of 1.
Agreed
The 3/8" should, on the same size bolt, in theory, should be able to deliver slightly more energy to the bolt, since the 3/8" anvil and socket will have slightly less mass, which means less inertia to overcome.
The way I figure, get the 3/8 for compact and mid-impact wrenches, and get the 1/2 for high-impact applications. Why haul around more mass if you don't need to?
Would be curious to see the life span difference between the two based on the same force being applied to two anvils of a different mass.
Yep, that's what I went with.
@@danrich6448 probably a insignificant amount
You want more mass to break jolts loose not less
This is why weighted sockets are a thing
Can you try this test with the 3/8 and 1/2 mid torque wrench’s?
Yes!
Just wondering if Milwaukee ever got back to you guys about the results… thanks
Harmonics are different using different sockets, thus vibrate differently. I think it has more to do with them being different socket set ups.
Maybe it’s the socket weight. the 1/2 socket seems shorter, if it weighs less it might be the cause for the lower readings
I could see that it would make a little difference, but not this much. Thanks for watching.
It would be the opposite. A lighter socket= less rotational mass. It should help, not hurt.
You have a heavier socket (and adapter) on the 3/8 drive than the 1/2 inch drive. Surprisingly, It makes a difference.
I would like to see the test without the 1/2 adapter to 3/8 or put an extension on the 1/2 to be the same. Most of the time if you just need a little more power you can add an adapter to help the impact loosen a nut. It helps the impact break the nuts free with that little extra space between the socket and the impact.
Odd. My 1/2” stubby will generally remove something my 3/8” cannot. I’ve done this on vehicles alot and usually the 1/2” is always the one that gets it done.
That's 100% socket weight... try to find some weighted socket you will see a massive difference between a cheapo socket and a thick one
@@silula21 is the heavy socket preferred?
A man that knows his physics! This is all due to the weight of the socket. It's Speed x's Mass = Force. When you cannot remove something with a small socket, get a bigger socket and the impact wrench will remove it. You don't have to pay for the 1/2, you can buy the 3/8 and just buy larger sockets.
@@TechieTard - i dont get it, do you mean heavier sockets?
Can you please do the same video but with the Milwaukee 3/8 and 1/2 mid torque impacts? I understand there's a 50 ft-lbs out put difference but I'm very curious about the results.
I don't believe that we have both mid-torque models, but we can check. Thanks for watching.
Thank you for the response. It would be awesome if you do have both models. I'm sure there are plenty of us that are curious about the results.
The adapter adds weight and will increase the hammer force of each impact. Noticed it first time on Detroit Diesel engines main bearing bolts. They are tightened to around like 600 foot pounds it’s a torque to yield bolt so not sure the full torque but the big 1/2 Milwaukee would only break those loose if I used a 1/2 to 3/4 adapter if you used a strait half inch socket it wouldn’t break them loose. But was still super impressed it could break those bolts loose it’s no joke trying to torque them
Great video!
Can you make a video comparing the 3/8 with the welded adapter and with a normal adapter that's not welded. Does the welded adapter provide any advatage that will not be experienced under normal circumstances with a regular adapter?
I would be curious your testing difference between the Milwaukee XC5.0 vs HO6.0 as the 5ah uses 18650 cells (20A per cell) while the 6Ah uses the 21700 (25A per cell) which are 25% higher output. Keep up the great work!
Wow..shocking results…3/8. ..glad I got one…awesome informative video…
Glad you liked it! Thanks for watching.
Maybe the slop is helping improve the hammering force kindof like how if you can’t pull someone out of the ditch with the strap tight you put slip in the slack in jerk on it and you get it
Glad I got the 3/8 mid and the 1/2 high. But I would like to see if you can get the batteries to fall off. I hear about this from alot of techs. I am a diy'er and don't use as often as a tech.
We have not had issues with batteries falling off our M18 tools. I know that M12 batteries can break the tabs when used a lot, but not so much the m18. Thanks for watching.
Can I ask why you use such a big socket? 33mm on half in is about as big as you’d go. And why not just use a size that is compatible with 3/8 and 1/2 inch? Wouldn’t that be a more comparable test?
In order to test these impacts, we have to torque these nuts/bolts to 500 ft-lbs. Even these large fasteners are reaching their point of failure at this point. Anything smaller would definitely fail. They don't make a 33mm socket in 3/8". Thanks for watching.
@@Shoptoolreviews yeah put that way it makes perfect sense I obviously didn’t take into consideration the amount of torque needed to test these guns now. Keep up the good work!
Love the mid torque - it's a beast. The impact driver with whatever anvil you want on it does 200 ft lbs. Wish I could have one of everything but I'd rather have an impact wrench with similar specs. I guess if you put a 3/8 anvil it will be even stronger than the 1/2 I've been using:)
Wtf is wrong mine wouldn’t break 120ft lbs lugs. Just got the 3/8th drive and couldn’t brake like half the lugs at work
@@user-white007 dude thats a kick in the teeth
Im planning to get one of these tmrw new in box for 120$. I’m going with the 3/8 model. Seems like well enough power for what I need and I have a lot more 3/8” sockets than 1/2”.
Having the adapter may very well provide twice the impact. During each impact the adapter is struck first followed by the socket. The torque is released and repeated each impact. Both impacts (adapter and socket) affect the fastener leading to twice the number of impacts.
You lose torque with longer extensions. You can find this out by using an impact with and without an extension and find yourself loosening much slower with the extension added.
What would happen if you welded an extension on the 1/2" socket. Like a inch long extension
I just bought that half inch torque Driver…. I don’t get too crazy on the specs and what not but I know that every time I use it under the hood of my car‘s and for any other rusted bolt it has perform Great…. So I am happy with my purchase… but great video it’s always good to see how they perform against each other… thanks..
Great Channel man! I always have these self conscious arguments in my head about which tools are better between each other. Thanks 💪🏼
By the looks of it in your thumbnail the 3/8 impact looks to have a longer heavier socket which if you watch mrsubaru’s video he has shown the difference between lighter and heavier impact sockets. I’m not saying it’s all from just the socket but that would help it slightly
Yeah, I could see the heavier socket making a small difference, but I'm not sure it would be this much. Thanks for watching.
That Mr Subaru vid definitely explains a lot .
@@Shoptoolreviews the mass difference between sockets makes a substantial difference. It's physics. Objects in motion want to stay in motion. [F]orce = [m]ass[a]cceleration ; F=ma
Went out and bought a 3/8 this week and I saw there's the same thing in 1/2. About capped my pants but after seeing these videos I'm happy with my purchase again
So glad to hear that. Thanks for watching and have a great day.
Im sold on the 3/8. Ordered lol
2855 is a lemon! By any chance, is there a theoretical number or range of numbers should we fasten a m14 x 1.5 lug nuts for 2 full seconds? I was wondering if I can get to the 100 ft/lbs mark in 2 full seconds run. Thanks for the great content.
Are these compact wrenches worth buying if you have the Mid-Torque 2962 1/2 Impact Wrench? All I see is it's 1 inch less in length and 1 pound less in weight. I don't think it really is.
sometimes the sockets matter, for instance i was trying to take out a bolt using a matco mid-length impact socket, the bolt would not budge, switched to a snap on deep impact socket on the same gun, took it off the bolt in 6 seconds. The snap on impact socket had a much thicker side wall. maybe the difference in socket affected the results?
u switched out the battery, but kept the same socket.
So i got the 3/8 version with a 3.0 battery and i just love it. It was a tuff choice over the stubby by im glad i got it. Rated at 250 ft lbs but i swear it has a little more kick than the M12 stubby. It also feels great in my hand. I can get to all kinds of tight places. Yes there might be a tight spot that the subby my fit better but for me its kinda rare and im never afaraid to grab a wrench. Conclusion: I really love the 3/8 M18 AND 3.0 BATTERY. Yes, it struggles with larger tuffer bolts but thats what my 2967 is for.
I say go with the size that best matches the drive size of sockets you use so you’re not adding length with an adapter.
I believe the difference in performance between these two are just normal manufacturing variation.
@10:11 you see clearly why there’s a difference. In performance just by looking at the sockets side by side.
So you basically demonstrated how heavy sockets work. Get an half in dr socket to the one with the 3/8 dr one and re test.
Also you could weigh both sockets, and I bet the percentage difference in weight, will correlate almost exactly to the average percentage difference in our put.
am going to switch to 2854 M18 FUEL 3/8"
Maybe the difference in socket brands and size/length. Maybe the length of the socket will give more vibrations.
I think the 1/2 inch isnt broken in yet vs the well seasond 3/8 impact after you put some miles on the 1/2" I think we should revisit this review 😉? I own these tools and have a question is there a break in period for the motors planetary gears anvils and so forth so my question from out the box is there a period of break in I will contact milwaukee and ask these questions unless you already have the answers please get back with me on this thanks brother have a wonderful day
Difference is most likely in the socket. The socket used in the 3/8 is heavier which equals more moving mass.
I have a question on Ryobi brand. I started with them 8-10 years ago, whenever they came out with the 20” mower & weed trimmer in the 40v. I have since been using their 18v (One+) tools as well. I have to take apart their battery packs (mainly on the 18v) to repair them when they fall below voltage where the BMS turns off the battery. Anyway, I was wondering if you had a comment on the Ryobi for quality? I do know there are DeWalt battery problems as well as Ryobi (I don’t have any experience with Milwaukee but since the same TTI owner owns most of those I would asssume they use similarly battery technology. Thanks again for your videos. I have seen several of your videos with the same metal plate with those nuts on that metal plate. Good job!
I wonder if you should switch the batteries from the 3/8 to the 1/2?
I was thinking the same thing!
On the 3/8s you have a higher weight socket with the adapter. The extra socket weight helps
Also less mass on the anvil and counterweight. Thanks for watching.
The stubby is aimed upward while this tool is straighter. I love the M18 compact. Its 229.00 at Home depot. Its 29.00 more than the stubby.
Genial!!! Ahora voy ppr Llave de impacto 2854-20 de 3/8.. las pruebas demostraron
su capacidad de fuerza aunque con características similares
Ya tienes la demostración de la llave de impacto de 2962P-20 ????
I have both of these and I never use them because they are just to weak. Go with the mid range. like the 2962 It Works!!!
How high can the grey torque impact with the arm go? use one that we have to tow a compressor around id like to look it up save alot of Hassel if we could just get a few batterys instead of towing
TIM from Canada to answer your question which one would I use it would depend on what jobs I am using it for.. if basically I am only using 3/8 sockets then the 3/8 drill would be the one.
If I was an automotive and I was using half-inch then the half-inch would be the one.. it depends on what job you are using it for if your work only deals with 3/8’s then that’s the one if your job only work with 1/2”inch then this is the one as I said before it has to deal with your job and what you were using it for
The only way to determine anything is to get another 1/2 and 3/8 impact and repeat the test. People keep suggesting that the extra weight of the adapter was the difference. The couple of ounces, located as close to the center point as possible would never cause 150ftlbs difference in performance.
It seems like the 3/8" socket is different from the 1/2" drive socket. The 3/8" drive socket with the adapter is heavier and harder than the 1/2" drive socket. The material CrMo socket is better than the CrV socket. CrMo socket has higher momentum and harmonic than CrV socket.
You should’ve tried it with the same socket. The adapter probably didn’t add much weight. But that bigger one looks like an axle nut socket, they’re heavier than a standard socket.
i think its the density of the socket ? the 3/8 has more material than the 1/2 inch
Before watching, my guess is because the heavier socket maintains and compacts moment as it impacts.
Welp nevermind lol, I guess you're using the same socket.
Oh hey, so the 3/8" made more power? Maybe the additional weight of the adapter helped a little.
What Gen is the 2854 in the video? 2 or 3? Home Depot is selling Gen's 2 and 3 of the same model. I need the one that's in the video. For all I know they could've nerfed the Gen 3!
Very interesting video. What tool do you use for torque wrench (cordless)?
the adapter appears to be welded to the socket, increasing the mass. if you us a heavy socket to take off fasteners can't compare
Is this the most powerful milwaukee half in or what's the next one up
Can you do this same test with Hercules vs Milwaukee 3/8 impacts.
It's because the 3\8 has a adaptor whick adds weight, when you add weight to a socket it performs better.
Once again loving the videos thanks
I still use my ole Ingersoll rand 231c 1/2 inch air gun , one I've had for 40 years , they break anything loose that I've ran into , except semi lug nuts , yeah sometimes it will break them loose , but never try tightening them and sending it without a torque wrench , nope standing on a long bar ..no good either ....gotta have the expensive 1300 ft lb torque wrench , ask me how I know..😁
I lost some semi duals a couple times trying it out ..
So if the Milwaukee 3/8 does 500 ft-lbs does it beat the new DeWalt Atomic 3/8 impact wrench since the Dewalt Atomic 1/2 only does 450 ft-lbs??? It seems in the reviews on Home Depot the new Dewalt Atomic 3/8 impact wrench is not getting as good reviews as the 1/2 model....
What was the combined mass of the adapter and socket used with the 3/8" drive vs. the mass of just the socket used with the 1/2" drive? If you used a deeper socket on the 1/2" drive to make the differences in mass more equal, I wonder if the results would change.
i know they say heavier sockets are better but ive on multiple occasions raddled on a lug nut with a deep impact socket to no avail then threw on the shallow socket from the same set and right away it undid it
The adapter should decrease torque regardless of adding mass, imo.
The adapter mass definitely plays a part in torque....I always have more power with more weight in the socket. Also not all impacts perform the same....it's like an engine produced, some engines have more power than another of the same engine on the dyno. I bought a mid torque Makita rated at 740 ft/lbs nut busting and my M12 Milwaukee 1/2" stubby out performed it! Obviously I think something was wrong with the Makita but it worked and sounded normal, but I returned it cause it was useless to me.
What happened to the follow up with Milwaukee
Did you recharge and swap batteries and retest?
