Did the 3/8 anvil not require modification like the 1/2?
It did not - fit right in without modifying the housing!
Hey, @@PhillyFixed any chance that you could upload a video of a slower tear down and rebuild of the drill? I’m trying to do this mod and am running into some issues. Thank you so much and keep up the great work!
@@Nicky14P sure, I could do that. What problems are you having?
@@PhillyFixed I ended up figuring it out! This mod is outstanding. Having a compact tool like this is so neat. Thank you so much for sharing.
I just did this as a present for myself and it’s 100% worth it. Thank you a million times over. I wish this was sold as an actual product so more mechanics can use it.
That 3/8" is a tiny little beast.
Man this is awesome. Great job making these tools and I'm looking forward to seeing our guys at TTC finding out what kind of numbers these will make.
Cool video Jim! I appreciate your hard work that you put in your videos.
Pretty interesting results thanks for taking the time to do this Testing and for sending them to torque test channel. I'm glad to see when you two Collab on a tool or tools. I would be curious to see how well the 3/8 drive would have done without the adapter.
Great job!!
Whats crazy is you lose a pretty good chunk of torque going through adaptors and the 3/8 still performed way better than the 1/2". Torque test channel showed about 27% loss with 3/8 -> 1/2"(although on a much higher power impact). If you were using 3/8 impact sockets with no adapter you might be able to comfortably remove 300 fl/lb
It really is cool whenever mods like these are so easy
I took the 3/8 gearbox out of a Kobalt impact and slapped it into the XTR 1/4 impact housing. They are the exact same dimensions for swapping the 3/8 into the 1/4 tool, but if you want to swap the 1/4 gearbox into the 3/8 tool, there's some grinding you gotta do
I like the higher RPM and IPM of the XTR driver for removing bolts
Wow that’s a mix bag in the results I’m impressed with just how powerful it is just in stock.
LET'S GO!!!☝️
Every comparison that I've seen with a 3/8 versus a 1/2 on the same tool the 3/8 always comes out ahead...
Yeah, I thought it was weird on the Milwaukees as well...
Technically yea but if you got big 1/2” sockets the adapter slack is going to eat up your final torque output. That’s why I got the 1/2” for big bolts that need all the power I can throw at it. I use a 3/8” adapter most of the time with smaller sockets.
I modified and used my 850 for the past few month, and I like it alot
How is it holding up?
I did enjoy it sir
Thank you very much for this video, I waited for someone to test it. When finally will arrive my anvil I'll do it.
Tool steel is tough unless softened. Good job 😊
Thanks for the video I'm a new subscriber I live in South philly glad to see you
Welcome!
Yolo I’m doing it DCF850 with the 3/8 anvil mod. I got the bigger DCF921 1/2 anvil and it’s cool but I have been working in really tight areas and it doesn’t quite fit so I had to use a hand ratchet. I couldn’t use my electric ratchet since I needed more torque. If I had one of these it would have been super easy.
I died 😂 when you pulled out the Flex. Been so busy with work and my son I missed this one Jim. Just caught the whole vid. Love the mod brother. Looked like that was some pretty tough material to drill
honestly kind of fascinating. I dont really need a 3/8th inch impact, but it would be nice to have for some of the smaller tasks I dont feel like doing by hand. and an 850 adapted would be about 100$ cad cheaper than the 923.
Hey u should try to see if your able to swap the membrane buttons from the dcf923 onto the dcf850!!! It looks like there's enough space allowed for it...also love the 3/8th drive onto the 850!!! It's my go to now for when working on my truck
You know what you must do. You KNOW.
Do I....?
You should do a shootout between the 850 with 3/8 anvil and the rigid 3/8 subcompact impact wrench.
yes, I want this too.
The new one or the old one? Old one... This tool wins... New one may win as it's been beefed up a bit
@@mike_t_007 my comment was made 6 months ago before rigid updated their subcompact. Regardless if the new rigid can beat the 850 or not, it cant beat the 850 size.
the 1/2 took longer because the hammer is hitting a bigger mass. Drill out the center of the squar like on the Bosch which have integrated 1/4 hex inside
Came across an old nicad battery brushed DW051 12 volt 3/8 impact at my local habitat ReStore turns out that is an acceptable anvil to do this mod as well
I still say, the compactness of the 850 is awesome, and would be EVEN BETTER, If they made a 12v version! That with maybe 12v Powerstack? Or even just the 5ah, would be awesome.
Very interesting results! That certainly does hit pretty hard for an impact driver, the Hart impact driver can do 100lb-ft lug nuts but it takes a while...
hold the socket it helps
Can I get a part number for the 1/2 anvil that was used? Thanks!
Hey do you think you can 3/8 anvil swap the Hercules HCB81B ???? Any help would be much appreciated!
💪…..eh hem, Gen 3 sir. Thanks!
i did this conversion tonight, what a bugger that inner C-clip was the clip to undo old part 1/4" anvil and the 3speed switch has a little flat metal tension spring retainer for plastic slide button be careful not to lose it and remember to put it back in after disassembly..mine fell out when i opened and had to figure out where it belongs. lol..all good now and up and running with a 3/8" anvil..all in all 158AU for tool and 28Au delivered "aliexpress" for anvil N646882 2 weeks to Australia..tools used a T10 torx bit,couple flat head screwdrivers for c-clip disassembly and little pick or fine knife to lift stickers 3 of them top,bottom and near 3speed switch..
Nice work! Yeah I could do a follow up with a bit more detail on the conversion, it sounds like you learned all the same hard lessons I did, haha. In fact, the 1/2" is missing that metal piece on the switch and so basically the switch doesn't "click" into each setting anymore, it slides without much resistance.
@@PhillyFixed Thank's..Mate without going into too much detail on c-clip i stabbed myself in palm with small wiha screwdriver hehehe "self inflicted" i dont have circlip pliers small enough so it was the hard way as always ..that 3 speed metal piece i left out at first not intentionally but after assembly there was a piece left over, "you know that DOHH moment" and had to unzip unit again "no big deal"..don't know if i will ever reverse process as there is a lot of parts to reverse process in that 1/4" setup..Thank you for your video did indeed help me to be confident to tackle this project..
Bigger sockets give higher numbers would like to see the same test with the same size socket
Can you do the conversion on the Skil 12v right angle impact? It would be the tiniest right angle impact wrench.
That's an interesting thought, but looking at the head housing I don't even think you could get an anvil in there from any impact wrench model...
looks like the 1/2" lag numbers are mixed up in the last chart. That would've put the 3/8" impact even farther away from the other two, which I believe would've tied with the correct numbers.
Other than that pretty good content as always.
Ah, you're right -- but, only a 2 point difference. Good catch!
If you get a chance to grab that new kobalt impact driver put it up against the old model 🙏🏼
Here's a preview! www.tiktok.com/t/ZTRapoq7h/
Do you have a video of making them??
I don't, but the 3/8" is very easy to do.
About time you made a video lol
You're not wrong 😅
You can buy both impacts in 1/2 or 3/8 in drive...
I assume you mean the DCF921 and 923, but they're at least 3/4" longer.
Awesome video Jim, I bought the 840 and was so happy with it I ended up swapping out/replacing the 1/4 collet for a 1/2 in hog ring anvil on my lightly used 887. Just my opinion but I feel like it actually has more effective impacts with the 1/2 anvil than original configuration and I also just needed a light to light mid torque wrench and my 887 was out of the starting lineup, I was pleasantly surprised how well it performs. Thinking maybe 3/8 anvil comparison might be insightful 🤔
will this mod work on the DCF885?
LOL, when woodworkers try to be metal workers 🤣🤣🤣🤣 Not to worry watching metal workers try and work wood is even funnier.
Hi. Thanks for this great video. Could you share the 3/8 anvil part number and where to buy it?
Just added a pinned comment 👍
@@PhillyFixed thanks!
Man caver tools just did his but with a 2 way anvil.
Where do I or can I buy one
I am planning to do that! Lol
Which 3/8 anvil would fit into the milwaukee m12 fuel impact driver
That's a good question, not sure. There may not be an existing one that fits...
Maybe I missed it, but what brand of 1/4" hex adapter is being used? That thing impressed me most of all! 😁👍
DeWalt, believe it or not!
@@PhillyFixed Hey, aside from saw blades, I like Dewalt accessories. My Makita XPS 1/4" hex-1/2" square didn't last one lug nut last time I rotated my tires. 🤦♂️ Of course, I should've used a breaker bar, first. 🤣
I wonder if the DCF921 anvil can be swapped for a 3/8" anvil in the same way? And which model of anvil could be used?
Just buy a DCF923 instead
Hey Jim, the problem ins DeWalts quality control is so lax, that you really need to do this test on the EXACT same impact driver, as I purchased 2 850s at the same time and they are vastly different in speed of task.
You just have to ruin it!
Well, he _did_ have to make modifications to the tool for the 1/2"anvil to work, but I guess you could just swap the metal endcaps along with the anvils.
Yes I also found this to be true. The grease they use from factory isn’t good. It’s supposed to be a little abrasive and help seat components together. After a while the grease wears out, so it’s a good idea to wipe it off and add quality grease. Don’t worry about getting all the old grease out, it will eventually all get replaced by the new grease. I personally grease all my tools every 3 months and they work great.
@@markm0000 disassembly the only way to grease? Will needle greaser work?
@@TheTurbomopar I take it apart and put a thin coating of fresh grease over each of the parts. If you just use a needle greaser it might not get to the very back of the gearbox. I recommend Valvoline Moly Full Synthetic NLGI 2.
I don''t think is makes a lot of sense as a 1/2" unless you only have 1/2" sockets. As a 3/8's I like it for it's compact size. However I gave up on Yellow and black tools after being let down too many times. The red ones are just better
yeah I feel like if you need 1/2" sockets, you are probably doing something that requires more torque/break away torque than the 850 can handle, and would probably just be better off with the 921. for 3/8th inch though this seems like a good idea
is there a 1/4 anvil consersion ? part number? as i have an extra to play with!!! ty for your channel and ideas free to all
I'm not sure about a 1/4" anvil... DeWalt actually doesn't make a 1/4" impact wrench that I'm aware of, so you'd have to find one from another manufacturer that fits. Makita and Milwaukee have 1/4" models, for example.
@@PhillyFixed mac tools mcf901 is a dewalt ????
Sorry, I should have said there's no 20V 1/4" impact wrench. The 12V Mac is basically just the Xtreme impact driver, and the nose housing on that is much, much smaller than on the 850. You could give it a shot, but I doubt it would fit.
so what happens if you put a 3/8 in a ct9080? or a dcf900
Explosions, I assume
Can you test the Kobalt next Gen midtorque impact wrench against the Kobalt XTR?
You mean the XTR high torque? Or a modified XTR impact driver?
@@PhillyFixed The XTR high torque. I recently watched the next gen kobalt midtorque removing a nut set at 1000ft-pound.
You considering getting a lathe after that headache?
Nope, I'm considering just never doing metalworking again.
@@PhillyFixed Awww. Too bad.
Can I get the link on how to make it?
I didn't do an instructional vid, but for the 3/8" you only have to take the impact apart and replace the collet with the new anvil. Very simple! I think Man Caver Tools did something similar except with a Bosch "freak" style anvil and did a vid on disassembly.
Oh wow... a hollow anvil 💐
I wonder how much impacting force is lost because of it being hollow
It should, in theory, do the opposite. The more mass there is out at the edges of the anvil, the more centrifugal force you get. But a lighter anvil is easier to spin. So you want to balance overall weight with mass on the dogs, basically.
Do you sell the 3/8 modified DeWalt tool ?
No, but it's really an easy mod to do yourself. No drilling out of the metal housing required for that one.
I was getting ready to try this on a 1/4" anvil would you recommend this? Or is it possible?
I haven't researched what 1/4" anvils are available - off the top of my head I can't think of a DeWalt 1/4" impact wrench on the market. But, at that size you're probably better off just using a socket adapter, you're not going to get much out of an anvil that small without breaking something.
@@PhillyFixed I wanted to use it for light applications like the makita 1/4” impact. I didn’t know dewalt didn’t make one. I just ordered one anvil for the Milwaukee which I’ve heard people are doing swap with. Is it likely to fit the dewalt?
I am interested to know how this compares to a DCF923b. What are the differences? I don't mind building this if it is going to be better for me than buying a DCF923b.
The 923 definitely has more torque; unless you need something as short as possible I would stick with the 923.
@@PhillyFixed Okay. That's exactly what I figured. Thanks for the clarification! For my purposes, in 3/8, being more compact is better. I could only find the 850 for $159 but the 923b is $127 on Amazon right now, lol. Any ideas for better priced 850's?
@@TarterSauce I remember last January the kit with 5aH came with a free 5aH on a BOGO special, and if you returned the extra battery the whole kit was like $100. Maybe they'll bring that back for the holidays? At Home Depot
@@TarterSauce HD has a sale right now. I just ordered. $199 for 4amp and 6amp and fast charger and you get DCF921B for free. People commenting that last time similar sale sold out quickly and never restocked. I would rather the 923 (3/8”) but honestly I would use this more for larger 1/2” sockets anyway
@@PhillyFixed similar deal is back. 6amp and 4 amp and charger and get 923b for “free” $199
You should not be using adapters when trying to get accurate measurements for a impact, the looseness of the adapter causes some of the impacts to not get full hammer power. Just a thought...
You're not wrong about losses, but try finding a 3/8" drive 1-1/8" impact socket ...
Made myself one 3/8 850 Frankenstein definitely not impressed with any of the new DeWalt brushless motors.
😎🛠️😎🛠️😎
I wonder why Dewalt does not offer this version, maybe longevity issues.
I think they just want you to buy the DCF923 instead
Their DCF923B has a ton more power at a very reasonable $140 bare tool (if you look in the right place), and it is not much bigger.
@@l00nybin For someone like me that is working all the time in very cramped equipment, I absolutely need something smaller than the 923. This 850 with the 3/8 anvil is about the size of my fist with a ratchet. I could never break loose something torqued at 212 ftlbs with only one arm and a few inches to spare. This is a massive time saver and I'm barely scratching the surface on where to use it.
You made a mistake in your chart, the 1/2 did 33s not 47 on the 1/2 lag.
Good catch, thanks!
Ow your showing offf omg
I dont any comments TH-cam, whats the deal
Above the comments area, tap "Newest" instead of "Top" and they should display!
See? SEE?? This is what happens when you use the right f*ing battery!
kind of cruel on this vid, i saw in the intro that my 850 was coming out of anesthesia early and you didnt do ANYTHING to help... smFh.. SFMF
It's always ruined in Philadelphia
I thought there would be a video showing how to do the conversion. I couldn't find it, but I got it done anyway. Makes a sweet, compact, ⅜" impact! Thanks for the video and links to make it possible!
I did it a couple days ago and it's the best tool in my entire toolbox. I have a dcf921 1/2 compact and having that extra inch of space really makes a difference. TTC did tests on all of these and this little 3/8 is 70% of the power my 1/2 has while being an inch shorter. What an incredible machine.
@@markm0000 I had a spot that I couldn't get my ½" mid compact in and then that's when I started doing research on the most compact impact. I came across this in my process, and like you, this is my go to impact everytime. I even used it to remove and fasten 24mm lug nuts on my tractor yesterday when fixing a hydraulic line. It's pretty spicy!
@@kanehoward7050 That's so cool! Someday Dewalt will release this and we're going to look at it like "yeah, I had that a year ago" and just laugh haha.
@@kanehoward7050 Also Happy New Year! I hope you set some good goals for next year and stick to it!
@@markm0000 thank you! Have a happy New Year!
Super cool. I did this to a Kobalt XTR awhile back and submitted it to TTC. Hope to see them do an episode on such things. ⅜ seems to do much better on smaller "wrenches". I also find it to be more versatile than ½ below 400-500ft/lbs. Great video as usual, Jim.
No spoilers for this Friday! Haha thanks again man
