- Our lifetime of TOOL RANKINGS torquetestchan...
Bosch: amzn.to/3X2RBxN Octane currently just $106: amzn.to/3WYOsiL Ridgid: amzn.to/42BGL3c DeWALT: amzn.to/43VyvvO
On todays episode we test some of the most request cordless 4.5" to 5" angle grinder from our viewers, the all new Bosch GWS18V-10N, Ridgid Octane vs the Brushless R86047B & DeWALT Flexvolt Advantage DCG416. Really impressed with some of these later offerings and the direction things are going here. More to come!

As always, the creator of this channel works in product development for Astro Tools, who don't make cordless angle grinders but it's worth knowing, always consider multiple sources when looking at a tool!
The Bosch is currently around $144 with some type of promo going on: amzn.to/3X2RBxN
The Octane is just $106: amzn.to/3JuBIuq
Ridgid Brushless $145: amzn.to/42BGL3c
DeWALT $165: amzn.to/43VyvvO
That octane is a steal!!
@@dingusbingus8554 Josh who we got these from prefers the Octane over Brushless for the extra RPM FWIW too
@@TorqueTestChannel Have you done a test for the Craftsmen brand battery angle grinders?
Xgt? Why include a 60v dewalt and not a 40v makita ?
Would love to see 7 inch corded angle grinders tested that have 10-15 amp motors.
Thank you! Vibration is massively under-rated. You don't realize how much better a tool can be until you have a really smooth one for the same job.
i had that revelation with oscillating multi tools
1st with a cheap green Bosch (thats the home user line from Bosch here in Germany) that i hated to use for everything longer then a few seconds
2nd upgraded to a way better one from makita that was not as loud and felt better in the hands
3rd found corded an cordless Fein MultiMaster at work and i couldn´t believe how those felt, you could keep a conversation while useing and you couldn´t feel any vibrations
Fein would also be a nice addition to the tests here, cause they are a bit special with their focus not on wood working like Festool or Mafell but primarly on metal working (e.g. 4-speed drill (400rpm to nearly 4000rpm) with quick change chucks even for thread taps)
At 68ms2 you should only be using that tool for 3 min per day! That's massive
I had to get carpal tunnel surgery because of tool vibration. On days where I used a rotary hammer and grinder non stop for 8+ hours my wrist felt like they were on fire.
rite like when impact drivers are rated by inch lbs when as someone who uses them all day long, for me its about MODEs, weight, and vibration, plus battery length, none of us ever complain that its too weak, but often its to heavy , shit batteries, grip to big,small, and no modes.. SFMF
It is. I got an M18 grinder to replace my Corded Bosch for cutting and trimming thin veneer stone and it chatters so much with a diamond blade it's basically unusable.
I'm on Ridgid platform and have been avoiding cordless grinders the same way I do cordless circ and recip saws for lack of power vs their corded options, but you've got my attention enough with the grinder to give it a try for the smaller, quick jobs.
Great review, thanks for sharing.
Got a Bosch GWS 18V-15 SC, strong smooth, has 3 different speeds, a vibration sensor that shuts off if the grinder vibrates too much, and shuts off by sudden movements like from kick back.
I was about to suggest to include this more powerful grinder from Bosch.
Bosch understands how important it is to make the batteries as compact as possible. Milwaukee, DeWalt and others batteries are humongous, defeating the purpose of many of their tools where size and weight are key
What batteries do you use and how long do they last ?
I bought the Bosch 2 days before viewing this video after owning a DeWalt for 5 years. $149 with 4 amp batter and charger at Lowe’s
Makes me glad I chose my Ridgid angle grinder
I actually used it at work and blew my boss away with how fast it cut without stress
With that being said that DeWalt is absolutely insane but I'm not regretting my purchase
Pair it with the lsa, it's hard to beat
Delighted to see the Ridgid models did like I expected them to. Kudos to Josh who obviously has more influence than me! Having switched to from Bosch to ridgid long ago mostly because of battery prices I don't regret it I'll still take the Ridgids over the bosch, especially considering I have lifetime warranty on these Ridgid batteries. I can add that from my own experience to eat after hour battery does definitely perform stronger and longer, and I've used them through several charge cycles without stopping never had one quit on me! Bridget just released at 12 amp hour battery I would love to see you testes again with that! Great video I really enjoyed it!
I really like my Bosch tools. Even the freak is great within reason ( 1/2” or less bolts) and the free battery promotion is awesome
I own the DCG614, I’m in industrial repair and do a ton of cutting bearings off large fan shafts. With a cutoff wheel, (side load) the battery certainly runs short. With a flap wheel, you can push as hard as you want and grind long periods. I typically just use my 60v 6” Dewalt for large bearing cuts.
I like that you know what emissivity is and how to adapt to it, and avoid error with the tape. It was a trick that i was shown years ago in a thermal imaging seminar. Most people are not aware of that and state erroneous information because of it. Good job!
Makita 40v XGT test please. Also need to open up tools to check build quality, bearing size and branding of parts, wires, switches and circuit boards. Repairability, parts availability & costs, reliability and heat dissipation.
TH-cam channel Dean Doherty, repairs tools and has a few eye opening issues regarding Milwaukee and Dewalt tools also few others. Performance isn't everything if the tool fails in couple of years of light use, also if parts are too expensive that it is uneconomical to repair.
Please add some reliability or stress testing to your reviews. Or long term test results. I ask because your very unbiased to the brands. Thanks mate. Keep up the good
Oh my, this and project farm are having such an impact in my budget for DIY tools projects. Great content! Thanks!
I think the problem with both of them are sometimes going too deep on the cheap ass tools. I guess when they shilling out amazon links they gotta throw them in there.
I own the dcg418 6” FV model and use it nearly every day at work. I can say I don’t notice any cutoff and I’ve used it for 2 years, cutting, grinding steel and piping. If I have enough batteries i hardly every pick a corded one over it. I have no complaints
So I had the right instinct going for Bosch blue.
If you like the locking ring on the Bosch, check out their X-Lock system. Like their SDS system on rotary hammers and jigsaws, and Starlock on multitools (co-development with Fein), it makes the old systems look horribly cumbersome and slow. The BiTurbo/ProFactor grinder tested here is also available with X-Lock here in Europe. Makita has also started to sell X-Lock grinders and accessories. I've been using the system for a while now and wouldn't want to go back from click-and-go to unwinding by hand. It's extremely fast and foolproof.
I don’t think X lock will have legs outside a couple applications. Most users aren’t changing wheels every day multiple times, and in high use applications like that you’ll often see fiber discs with backers that can be changed very quickly.
@@G5Hohn even people that don't change drill bits that often don't want to go back to non-SDS drills. Also, there are other advantages, like a more compact tool head and more usable range for the disc. You might not use all the benefits all the time, but there are no technical drawbacks, and several advantages. The old system has always been archaic and should have been on the list for replacement for a long time.
It's like micro-USB connections: yes they got the job done, but it was a horrible solution, and even the people that said they didn't need USB-C, really don't want to go back after using it for a while.
@@macvos You say drill but I think you mean Rotary Hammer.
@@G5Hohn you're right. I used a too literal translation of the Dutch word 'boorhamer' or German 'Borhhammer'. In English it's indeed called a rotary hammer, with a hammer drill what we call a 'klopboor' ('knocking drill', since it doesn't have a hammer function). I've corrected my answer. Thank you.
@@macvosthe real / great disadvantage is that, it's way too expensive for x-lock or equivalent for most people. You don't have much selection too so either you got scammed by overpaying their discs or scratching your head when you need one immediately when no small hardware shops are selling it.
This has nothing to do with your test, but Bosch is still one of the few companies selling compact 12 volt tools. I just got a small grinder from them and it works great if you need something to fit in an inconvenient place, like an engine block or behind your HVAC.
Is that the GWS12V-30N 3" grinder that looks similar to the Milwaukee M12 2522-20?
Yes@shorty_lickens , tho that little Bosch mini-grinder has been around a long time
@@aha2551 Yeah, at least 5 months by my count.
So glad you tested the Dewalt Flex! I knew it was a monster. The Flex batteries seem to have overheating issues, especially 9ah and up.
The chainsaw has the same issue of seemingly overheating for no reason. Makes me nervous about commiting to that line.
I run the 9ah on a 60v weedeater and it never has any issues.
Likely the weedeater doesn't tax those batteries to he point of being warm like the chainsaw or grinder. You can find tons of testimonials of those batteries struggling. Probably why Husqvarna and other brands are now adding active battery cooling to their tools@@saltysteel3996
Would like to see how the Dewalt power detect compared against the flex volt advantage.
Yes we need a dcg415 vs dcg416 head to head, with the 6ah xr 20v batteries.
I can't prove this, but I think the power is the same with the same battery. Flexvolt advantage as a name will disappear as flexvolt no longer is the only high-powered battery. In Europe flexvolt advantage is already gone and replaced by "high power" and complimented with 5ah powerstack. I'm waiting on a flexvolt stacked battery with even more power, and a new generation of flexvolt tools on steroids
What about the 60 flex volt grinder too
Power detect is superior on the hammer drills.Dont know if it makes a difference in grinders.
I have a 60v dewalt grinder and it acts similar to this one. It will run like crazy with near corded power for a while then seems like It steps down into a reduced power mode. Switching batteries even if their not drained usually gets it out but not always.
I’ve been running a 54v flex for some years now (same thing just uk marketing) and I remember when I first got it I leaned on it as hard as I could to try and stall it out…. It just ate the steel even quicker. Did the same to my then equally as new 110v corded Bosch and stalled it out comparatively easy. My 1 and only gripe with the 54v (60v) is that it’s too long! On the batteries I did notice that even though they say 6ah, that’s actually the 18v part, the flex(54/60v) part is only 2ah, that’s probably why we’re seeing such a dramatic drop in run time
The 54v lasts shorter because of the power output. Flexvolt advantage delivers great power and better runtime. It also drops rpm at some point when you have two bars on 6ah, and maybe one bar on 9ah.
@@olgajoachimosmundsen4647 the flexvolt batteries can do both 54v and 18v. When plugged into an 18v tool it has 6ah, but when plugged into the 54v grinder it only has 2ah. So of course the 54v is going to have a decreased run time compared to conventional grinders. But here’s the big question, when the rubber meets the road, what is going to chomp its way through steel faster? That’s what I’d like @TorqueTestChannel to test next!
@MrArcticPower Yea same with me. I have the 418 and have zero cutouts with it.
Personally as someone who uses one of these things regularly, I think you guys are heavily undervaluing vibration. Vibration fatigues you really fast and while that might matter less for very short jobs, as you mentioned most of the time these tools are being used for the full duration of the battery and then some. Yes there are times where I wish my makita had a little more grunt and for those times I'll honestly grab the old corded. The rest of the time the difference in how my arm and wrist feels at the end of the day is absolutely massive. I have used a couple of these for a full day and hurt for hours after. The makita doesn't leave me in agony at the end of the day.
Would've liked to see the bosch gws 18v-15 tested instead, its the same size wheel with a stronger motor. The gws 18v-10 is the mid range model.
Power (watts) itself is rate at which the work is done, so it indicates how much material is removed in unit of time, not the RPMs. One with more RPM would take more power if it was really grinding.
I have a lot of DeWalt tools including this grinder, but my use is light. I briefly tried getting into the FlexVolt outdoor tools, most notably the shiny new (at the time) 18" chainsaw and this was exactly my experience. Immense power for a little, and then simply giving up if you continue to apply load. And a chainsaw is a long use tool! I was trying to go through 16-18" fallen trees, it takes some time. I gave up and swapped over to Ego, which brings much better consistency with their large and more thermally managed batteries.
Thanks... I am a pro using mostly bosch-- nice to know my hunch paid off.
I bought bosch because they were early with the big batteries and I have 2 or 3 corded tools torture tested for more than 20 years. (Barrel jig AND routers). Comparatively, we melted a Makita and Dewalt in a day of use back then.
I own 7 1/4 bosch and Milwaukee circular saws-- guess which one is in my hand most of the day?
I've been using the Milwaukee grinder (same one in the video) which I picked up on a good sale at home depot with two 6ah high output batteries. While it is not the most powerful, I was able to use it for over an hour of heavy grinding getting rust off of angle iron and it never quit on me. It did deplete every single battery I own though... But I am at least happy with it since I know it is reliable.
I've never had my DCG414s quit on me, I have 4 and use the piss out of them often nuking 6AH packs without letting off the trigger once, about 5-10 minutes use depending on load. They get warm, only. Legendary machines.
I own Flex dewalt, bosch, and Ryobi. The bosch switches off to frequently when meets resistance. Funny, the Ryobi is my favorite for larger grinder jobs. Usually has wire wheels on it. Dewalt for cut off disks, bosch just grinding.
it all depends on what models of each brand you've got.
There's an old brushed Bosch cordless grinder that pales in comparison to any grinders tested here but the newer ones specially the 13 amp equivalent PROFACTORs are no joke.
Testing with a load on the disk for vibration is important too. Some tools have enough gearbox play that they vibrate different when under load than no load
We agree with that, it just proved too difficult to keep static. The disc changes shape and weight, the thing you're grinding on moves away as it ground down. A static weight on the tool causes the tool to shimmy around, readings all over the place.
yeah, no matter how you test it it won't be safe...
might try removing the guards and affix the tools solidly to a rig, and use a pneumatic piston a set regulated pressure to push a piece of metal into the path of the wheel. (which you trial and error for a good working simulation, could use a tach or just feel it out, or do the math.)
it might be kinda tricky but it could be consistent between tools and you could also try running different materials, and Change out materials between runs.
you'd need the piston to push a block with atleast 2 secondary slides to keep it from spinning and the work pieces could be tapped and threaded to receive screws to bolt up to the block
if all else fails contact project farm, he might have a setup all ready made or had ideas for one.
I use tools like these really hard and I have for decades. The brands that I have had the fewest failures with has been Bosch and Makita. The ones that have failed the most are DeWalt, Hitachi, and Rigid. Do with that what you will. It is my experience in construction since the mid 90’s
Been loving my bosch 12v tools for years. Think I have 12 of them. Just jumped into the new core18v range. No doubt they will perform just as well. I'm a fan.
With Ridgid you have LSA ( lifetime service agrement ), with the cost of battery, I Buy a lot of Ridgid.
Nevers pay again for battery and i use adaptor for using Ridgid battery on Milwaukee/De Walt if Ridgid dont make the tool i need
Phew... hlad u clarified construction...I was thinking converter aquirer.
@@s13kuminachu Same here. Started with the 12V line, but now have their 18V stuff too. Bosch corded stuff is great too - especcially the jigsaws!
I’d love to see the bosch biturbo tested too
Suggestion: Test corded tools too, because I'm sure there are lots of other people who love their corded tools and hate paying for batteries... and/or just want a lighter, nimbler tool they can use all day without having to worry about the state of charge.
They're generally cheaper than battery tools, so I'd imagine it'd provide a lot of review bang for your initial purchase buck.
Maybe. So far I can say the only corded tools I'm still using are a sander (only because it still requires dust removal for optimal performance, so no real reason to get rid of the cord), the heat gun, miter saw, table saw, and a PVC soldering iron. As far as appliances go, I still run a corded vacuum for dust removal (my home vacuums are all battery-powered now), and pressure washer.
I also keep a corded angle grinder but only for large-volume jobs, which happen rarely, or to lend.
Battery tools are superior in most practical regards, so starting corded is of use only for very high power/runtime cases, or for budgetary reasons IMO.
I appreciate your effort on bringing some very thoughtful and detailed testing to the table.
Surprising results. I came surprised on how the Ridgid proved more powerful than the Milwaukee but the small price difference, less vibration and more expansive lineup would still gravitate me towards team red. I owned the 2880-20 which looks almost the same as the 2888-20, just curious to see how it'd stack up.
But I'm also very interested on seeing some entries from Metabo HPT, Flex and the top dog PROFACTOR from Bosch: GWS18V-13CN.
I have a DCG416 and i love it. Super powerful for what i use it for.
I'm glad to see Bosch putting in some R&D for new tools.
I've used their tools for a bit now and they have always had as better "feel" to them than the Dewalt and Makita tools I use at work. These vibration measurements are a good indication of that.
Actually.... In terms of dollars, Bosch tool group spends more on R&D than the next three competitors combined. I've been given that information by several Bosch factory reps. Unfortunately, we don't see the results of all of that research in the USA, because Bosch focuses on tool markets elsewhere in the world. In the USA, we generally get to see new Bosch tools at least a few years after they have already been on the market in other countries. Also, a very large market for Bosch is in the area of automotive assembly tools, which the general consumer never gets to see. They sell more tools to the automotive market than they do to contractors and users. All that does nothing to satisfy our wish to see Bosch "innovate and upgrade".... It just means they have other priorities...sadly 😢
I use my DeWalt everyday while building pipe fence and with the 6ah flexvolt it does great at removing material, I have only hit the *maximum runtime* once
I have the power detect dewalt, I’ve ran that thing nonstop(except battery changes) for close to an hour, and never once shut off.
Dude AWESOME video! The fact that you added all the different power batteries for each made the video 100000x better dude I watched this beginning to end! If you keep doing that on the rest of the tools your going to be LEGEND!
The dewalt real flexvolt is insanely powerful, I use one frequently when i have a quick job to do. If I need longer runtime, I use my old Walter 15A 7in beast! You really should look into the Walter grinders, they are in a different league. Keep up the good work!
Walter make some badass abrasive products too for industrial use. Not cheap but well worth what they cost.
Thank you for the reviews. Finally Bosch is on top. They never were in the first place but they always deliver quality tools for that just works beautifully category.
and that's not even their top dog in 4 1/2 / 5" category. There's a 13 AMP equivalent Profactor grinder I'd like to see as well just to know if it's worth the extra $$$
@@engineer_alv GWX18V-13CN? Do they make one without x-lock? We dont have a away to attach x-lock to the dyno
@@TorqueTestChannel they do. GWS18V-13CN if slide switch and GWS18V-13P for the paddle switch version. Although those are 4 1/2" to 6" class grinders
I work with grinders everyday 10 plus hours a day...I run a marine propeller shop and we use long head Metabo grinders and they take the abuse that no other can.😊
Holy smokes I need to go grab one of these flexvolt advantage grinders 850 watts with a flexvolt 9ah that's crazy
Ill stick with my makita......13 years later, still running like a champ!
I do tend to grab my makita Cordless Lxt xlock grinder over all my other grinders nowadays because the speed and easy to change blades but I got 20 grinders so I technically don't need to change blades just it's habit lol 😂 bit the makita xlock is so dang smooth don't matter if it's the LXT or the XGT
Thanks for the comment its helpful to me in my tool selection because you have a lot of experience
@@andre1987ephI'm glad my Comment Was Informative for you and Helpful best of luck on your Tool Search. If you have any questions don't hesitate to ask..
nice work, Would love to see 7 inch corded angle grinders tested that have 10-15 amp motors.
How about trying the Bosch GWX18V-13 (GWX 18V-15 in EU/UK), supposed to offer 1500w equivalent corded power?
Might compare more favourably in the power output but then it may not be as good for duration? Would be an interesting comparison.
Have you guys considered doing an overall brand to brand comparison? Meaning: if I were looking to get into a new battery platform, which one fares the best over all the tools you guys have tested? Thanks for all the great content.
Lol you're trying to get them sued or killed?
"best" is a subjective term. It varies based on your usage.
Pick the tools you will need and look at their rank charts. If you don't need THE most powerful 1/2in impact, why have that make the decision for you.
The tool lineup is what I'd be looking at.
I agree 100%. Other than bragging rights, these tests, while interesting, will have no bearing on which tool we will purchase if we are invested in one battery system already. So, which battery/tool system should that be? Performance, value, number of tools available for each system, availability.... would all factor in decisions.
That’s a loaded question lmao it seems every brand has that one tool the others can’t beat or don’t have a model of. I’ve found Milwaukee and dewalt are pretty even across the board still some tools will be better than others. Like if your main tool interest is a hammer drill dewalt is top of the walk and just recently they took over on the high torque impact.
They also don't test things like long term durability, resistance to damage from dropping, how long the batteries retain charge when not in use, warranty, warranty process, availability of service/parts, switchgear and long term comfort, ease of disc swapping, etc. They really put a lot of stress on power, but we know that's only one part of the equation.
Wow at the 8ah max output and the new Brushless Ridgid grinder that's impressive watts numbers
Enjoyed these tests. In terms of testing, one thing to consider for the future is testing the clutch/break when it binds. Even the worst grinder on the list is useable, but considering the grinder is one the most dangerous tools in terms of number of injuries per year, the safety features should be looked at. Aside from that, would have liked to see Makita's XGT grinders to compare against Dewalt's Flexvolt
Don't know about the other ones, but Bosch grinders are great in safety.
I just picked up the Flexvolt DCG418 6” grinder on Home Depot Special for $229 WITH a 9ah Vlexvolt battery for the mobile welding business, can’t wait to see that category tested!
I have the ridgid, it was essentially free with purchase of a battery on black friday. It's awesome, i rarely touch my 3 corded grinders now.
Thank you for making this video, I have both dewalt and the ridgid grinders that you tested. I notice ridgid brushless also sounds a lot quieter. TTI make all these grinder ridgid, hart, ryobi, milwaukee, even flex all looks identical. I wonder if is just different skin. Thank you. Great video
I have a Dewalt XR with a 6 amp battery and have no complaints. It's a beast!
The biggest surprise to me here was the Flexvolt revelation. Although, I am still suspicious of the DCD998 and 999 drills *not* having different circuitry, at least now we know that at least one FVA tool has a legit difference compared to Power Detect/generic XR.
I knew the 999 was bullshit. Still a great drill. I bought it with 2 5amp hours vs 1 9 and 1 2. Better deal IMO.
Well we need to see the exact same tests with the exact same batteries performed using the Power Detect grinder before we can truly draw any conclusion. It too may perform better with the Flex 6Ah vs. the XR 6ah.
Recently got a Craftsman V20 MAX angle grinder with a V20 MAX 7 Tool combo set (1) CMCS500 Circular Saw, (1) CMCF800 Impact Driver, (1) CMCL020 Task Light, (1) CMCS300 Reciprocating Saw, (1) CMCE500 Oscillating Tool, (1) CMCG400 Grinder, (1) CMCD700 Drill/Driver. I have to say, while using Walmart Hyper Tough Drill/Drivers for years that Craftsman and other main brand tools are a completely different beast. Havent had anything to use the grinder on yet, but at least i have it if i ever need it.
Recently, I used my DCG416 with a 6Ah XR battery (the largest one I own) to grind the mushroom heads of my grandfather's old chisels. It was a lot of on/off because I had to turn the chisel in the vice and swap them out (he owned maybe six or seven of them?), but it had plenty of power and the battery lasted the whole time, showing one bar remaining after I was done.
Very nice test again. But please start testing the Profactor stuff from Bosch.
As a new Dewalt convert I was a bit scared when I saw that cut out so early. I'm a metal worker and so that would just kill me! But the reality is that the power it has is so useful, it is easy to use, great quality, but for longer jobs I'm gonna set up my extension and run my old trusty corded beast - the only thing I need worry about is changing disks. So all good. Dewalt stays in my bag.
Lowes has been selling their DeWalt Power Detect Tool Kits w/ 8.0ah Battery for $249 , that includes the Grinder , I've had this Grinder for about 3yrs and never had any problems , but I use it more for cutting than grinding and never had to hold the trigger for more than a few minutes just enough to cut through something so I don't know how it would act grinding something for long periods , just my 2 cents , keep up the good work guys ....👍🖖
I have the first gen Milwaukee brushless grinder very hard to stall out.
Have newer model of it as well, it's more sensitive & cuts out a bit earlier
I would love to see one of the 40V Makita grinders tested here. I used one of them recently and it seemed to me like the rpm just didn't drop at all until it stalled out.
Im a mobile welder and use cordless grinders near exclusively. I have 5 dcg416 and none of them cut out like that. Ive warranty replaced 2 for other things but never experienced the cut out.
I also have the dcg440 7in and i really prefer the 416 over the true 60v models.
What do you recommend for a cordless grinder for welding? I want one for grinding. And one for wire brushing? I am heavily invested in the Milwaukee platform as i do mechanic work on my own heavy equipment. Thanks
TTC kickin' ass, "cutting through the marketing wank", and controlling for generalized Stefan-Boltzmann law variables 😁 - love this channel.
Interesting to see the 6AH FV beat the 6AH XR this time - good to know maybe it isn't entirely creative marketing liberties.
Disappointingly inconsistent performance & slightly generous ranking on the DCG416 IMO - the Bosch does seem like the best of this bunch. I would be very interested to see whether the DCG418 fares any better against its peers. Keep up the great content 👍
I had a lot of old pipes and rebar to cut up and from what I read th-cam.com/users/postUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 this would be the tool for the job. Since I had never used one, I watched a couple of youtube videos and I'm so glad I did. Some really good safety tips, which I followed, and this tool did a splendid job. One good thing to know is the weight of the tool puts just about the right amount of pressure on the metal I was cutting, so I didn't have to use a lot of pressure, which is more likely to jam the tool. It made fast work of my job.
Glad I bought the Dewalt
Love the vibration measurements! I own dewalt, Milwaukee, and Bosch tools. I will always pick the Bosch if possible. You just can’t measure precision of use and a well balanced tool. Not to mention the ease of placement for switches or knobs. I can’t even tell if this is the spitfire grinder from bosch. There are so many levels of each brand it’s difficult to find their highest model to put head to head.
10-15 minutes sounds about right for my Dewalt DCG405 on a standard 6ah battery.
I am a big fan of dewalt 60 volt tools, they may drain batteries like there isnt a tomorrow but I rarely dont get the job done with 2 batteries.
Very happy with my reciprocating saw, concrete saw (which I use diamond blades for cutting steel), and my grinder. Never really saw much of a difference between the flexvolt 20v and normal 20v
Excellent work as always. If you test 6" grinders, please include the new Metabo HPT Multivolt model G3615DVFQ6, the DeWalt Flexvolt, Milwaukee 2980-20, and possibly the Metabo WPB 18 LT BL 11-150 (German Metabo). Thanks!
Lousy warranty on those Metabo grinders.
Lousy warranty on those Metabo grinders.
Lousy warranty on those Metabo grinders.
Just used my ridgid brushless to grind a 9/16 bolt head off a carriable bolt. I will now watch the video
Milwaukee does have a bigger grinder I'd like to see you test that one too
Glad to see Ridgid tested and it's performance!
I assume most people who use grinders a lot have multiple grinders. I like to have a cutoff, a flap disc and a fiber disc so if I’m switching between 3 grinders that DEWALT might not be as bad but I’d like to see the larger one tested and also the hilt I nuron. Feel like the Hilti tools gets not attention do they suck that bad these days? I have the old brushed 12v hilti 3p set w 3 batts for light work and they are about 6 years old and still work same as day 1.
Would like to see you test the Flex grinder
I too would like to see the Flex grinder.
The DeWalt powering off was already documented by mathias wandel when he was building his powerfeed for the table saw, it will power down even WITHOUT A LOAD
I’d like to see the M18 FUEL 4-1/2” - 6” Grinder on here. Project Farm incorrectly put it up against the smaller 4-1/2” - 5” grinders in his testing and of course it scored 1st place. I wanna see where it really places.
Really appreciate the deeper dive into the rigid battery situation. It's very interesting.
Important note: Bosch products have kickback prevention, which is simply an accelerometer that turns off the power when it moved abnormally. It's not an expensive feature to add, so the other companies just don't care as much about safety as Bosch. The fact that Bosch also usually has less vibration than other tools shows that it's a real tool company, not a toy company.
Dewalt, milwaukee, and metabo hpt/hikoki also have angle grinders with kickback protection, as well as other tools. Many brands seem to these days
I really like that you take not only power but other properties as well into account.
I have my dewalt brushless corded grinder, and my flex cordless both are units, no complaints.
I’ve been running a 54v flex for some years now (same thing as 60v just uk marketing) and I remember when I first got it I leaned on it as hard as I could to try and stall it out…. It just ate the steel even quicker. Did the same to my then equally as new 110v corded Bosch and stalled it out comparatively easy. My 1 and only gripe with the 54v (60v) is that it’s too long! On the batteries though I did notice that even though they say 6ah, that’s actually the 18v part, the flex(54/60v) part is only 2ah, that’s probably why we’re seeing such a dramatic drop in run time. Even still, that amount of pure grunt is plenty to cut/grind everything I’ve needed to.
10/10 would recommend.
never had the cheapest dewalt grinder shut off on me. but most of the time i use it for pretty light jobs. getting paint off a spesific spot. wire wheeling a weld or cutting a small piece of cold role round. havent upgraded yet but i got the tool free part of an ace tool deal and if i had to i would buy one in a heatbeat. the 6ah flexvolt does work noticeably better than the normal 6ah battery
I prefer the Dewalt Flexvolt rat tail grinders over the flexvolt advantage
I'd really like to see a test of the Metabo HPT Multivolt grinder. The ability to run it corded for big jobs is sort of a best of both worlds situation in my books.
It’s also a really tough grinder last forever
BOTH models. the newest 36v one and the older 36v one. ToolsandStuff has a great grinder comparison video using the older 36v one and it came first in his testing!
I bought that Dewalt flexvolt grinder as a tool only since i already have some of the batteries for my FV circular saw and such. No doubt it brings the jam. It has all but replaced my corded grinder, it had turned into my go to for sure.
It's so good I don't even own a corded one. It's pretty much as good as corded
Not sure if you'll see this, but I have two "bumble bee" grinders I'd like to see tested for the sake of confirmation bias.
First is the DCG412 (brushed) since she's my main yard dog around here.
Second is the DCG418 that you did mention. That thing is a tank when paired with a 9AH.
Cheers from a fellow power too addict!
Makita just makes comfortable tools. My cordless angle grinder doesn’t bother my hands like other cordless ones. And I gotta say that Milwaukees angle grinder just feel uncomfortable after continuous use. Just my opinion
Would like to see the effects of adapters that allow use of one brand battery with different brand tools
@@johncoops6897 The latest video answers your question
The makita 40v is insane but also $400
Would love to see the new metabo hpt grinders tested soon.
I buy mostly Metabo non-hpt grinders these days, it would be great to see some of them featured in these tests. They brag about their fancy features like vibration dampening, clutches, brakes, etc.
They even have a 9" cordless option
Can't wait for the Flex grinder 💪
I have the same dewalt combo used with a 6 and 9 for almost 2yrs now and haven't come across a shut down li,e shown here wonder if there's something wrong with that one
On the vibration front, how do the measurements compare with the specs in the manual for each tool?
They have to provide vibration figures for hand arm vibration risk assessments.
Dang! My Rigid Brushless Grinder was free when I bought the Ridgid 1/2 in impact wrench after watching that video on this channel!
I would be interested in a comparison with the new ingersoll rand g5351m angle grinder. I bought it yesterday and my first impression of the workmanship is very good.
Great video and channel, I’ve been using DeWalt for well over 25 yrs I’m a huge fan of the product, well less then a month ago I purchased the Dewalt DCG416 I purchased some 20v 4AH batteries I been using it daily on and off throughout the day, yesterday I was ready to work I fired it up it turned on and when I touched the metal it shut down and hasn’t turned on since my I add it shut down a couple times before it finally shut down completely?
I was missing the Fein AGC 18V 5" runtime on 5.2Ah HO is about 11-15 min and its a beast.
Love the video! These grinders had me thinking of something I'm definitely curious about. I'm just starting out on welding and have been borrowing my co-worker's hood, would it be possible for a possible comparison on welding hoods on different budgets? Maybe like reaction time, sensitivity, image quality, battery life and maybe a suggestive comfort level? All just random ideas!!
"Happy days" indeed! I've verified that increase in power too on our dcg416. And after 3 yrs of use i've had no cutouts at all.
Patiently waiting for a video on the dcg418 and maybe the 440 too?
Yaaay, vibration test. More important (to me) than raw power. Thanks guys :)
