Large Angle Grinders: Some are Getting Insane

[@TorqueTestChannel]

The DeWALT is currently $144, I mean come on amzn.to/49oGLb2 $289 is their best battery kit: amzn.to/3OYZguw On why disc speed is important: Within X size of disc like 6" here, higher RPM makes for a more abrasive quicker working disc and an easier task for you. Abrasives need speed to be effective. Increasing load on the tool to do the same amount of work at lower RPM is not free in this scenario, it requires effort from you. Even larger grinders like 9" while lower RPM have larger diameter discs so a higher edge speed MPH and are even more effective. RPM during use will always be scored here, it's not the bulk of it's score, but in practical daily use it's a noticeable benefit.

That really is a screaming deal with that battery included.

I haven’t see you make any comparison video with the flex 24v angle grinder… I would like to see how far it is up on the rankings

[@default9740]

I repair tools…just worked through a batch of DCG418’s out of an underground gold mine. 🤢 Amazingly, with a regrease, most of them were fine. They sometimes cook off at the control board behind the motor, but have never found burnt windings on the stator. The dust screens are really effective as well, very clean motors after 2 years underground.

[@SteveSRT]

Pretty much all of my tools are Milwaukee except I have a couple of the Dewalt 60v grinders in our shop and for me personally. All of ours have the locking power switch though. We have a few corded metabo grinders but pretty much everyone prefers to use the Dewalt 60v units. They are just flat out beastly. Even the corded 9” Metabo sits collecting dust now. We do repairs on tractor trailer stuff with steel thicknesses up to 3/4” and lots of aluminum repairs as well. Even the most abused Dewalt in our shop by one of my employees still runs like it was new. Dewalt really knocked it out of the park with this unit and I can’t really think of much I’d ever change about it.

[@TheMetalButcher]

I knew the DeWalt would kick ass. I'd been asking for it for a while now. Thanks for delievering. Hardest grinder to stall I've ever used. I got mine at Home Depot over Christmas for $230, with the 9ah. An an amazing deal. P.S., mine is smooth with discs, but not with grinding wheels. I OD grind the wheels, they are rarely balanced. It is much smoother, quieter, and more powerful than the 416. Also in for your rating, factoring infinite batteries, the DeWalt will be much quicker. So if time is your money, it is very good value.

Needed another flexvolt battery and decided to do a kit, since you pretty much get a tool for free. A really good tool. Was in middle of a project where I was using a grinder a lot, I have the base DeWalt grinder and was satisfied with it, given what I use it for. I had no other use for the free tools offered with the flexvolt so I got the grinder. Holy hell!!!! The thing is a freaking beast. Cracks me up with Milwaukee fan boys think that the red tools dominate everything. (I have red as well).

I've used the DCG418. I've always suspected that it would happily grab along something and cut me up if I wasn't careful.

[@abpsd73]

I have the older generation 60V I bought a few years ago, it has some sort of sensing circuit where if a cut off wheel binds up, it cuts power to the motor. I was chopping off conduits on a concrete slab and it just stopped, I thought it was a fault or dead battery, but it fired right back up once I had the wheel extricated from the cut. I'm not sure if they carried that into the new design.

[@marekogarek6329]

@@abpsd73 It was an electronic clutch (only metabo has a real clutch on some of their grinders). Electronic clutch sometimes fails, but it's better than nothing and in your case managed to protect you from kickback.

[@KateNesD]

The kickback brake works great on it. Also as soon as you release the trigger it stops the disc almost instantly. Even outside of something going wrong it’s really convenient to not have to worry about it when you put it down somewhere.

[@AlamarianJ]

Metabo corded grinders are the gold standard in my trade, Boilermaking, to the point that “Metabo” is used as a synonym for “grinder”. Because nothing else will reliably last through 12+ hours of cutting through tubes or hogging off old welds. Sometimes a contractor will supply Milwaukee or Dewalt grinders and most of them will end up in the bad tool bin within a few shifts. Nothing wrong with those brands for lighter duty applications (I’ve had the same 4.5” Dewalt for ages) but if you plan to abuse your corded grinder, I would go straight to Metabo. (Battery grinders aren’t practical for anything but short jobs and their tendency to attract sticky fingers makes them a rare sight)

We use the Metabo variable low speed corded at work for stainless fab and they blow everything else we’ve used out of the water. No surprise it’s top of the corded chart. Their flathead grinder and pipe polisher is very nice as well. For cordless grinding I use a 36V Hikoki (Metabo HPT) and it’s been awesome. Easy to use one handed, compact and lightweight with the small 2.5Ah battery (I have a few in rotation). If it ever dies I’ll happily buy another. I want to try that Dewalt though!

[@Omnis2]

TTC overall Cliff Notes and Summary so far: If you need to cut stuff, get DeWalt 60V saw and grinder. If you need to fasten and unfasten stuff, get DeWalt DCF921(923) and DCF961 if it still won't turn. If you need to use smaller stuff but still need to do some bigger stuff and you have a breaker bar, get M12 stuff If you have a work crew that needs to fasten and unfasten stuff to rigorously scrutinized torques, get M18 one-key-cyber-e-connecto-tork stuff.

[@likeaboss882]

I bought one of the first generation flexvolt grinders, the dcg414 ages ago when they’d released it. When they introduced the second generation and larger packs, i was convinced they’ve got the most powerful grinder on the market. A claimed 17% increase in power over that one. Which is wild because it is not short on power. That first gen grinder is going strong still with GOBS of power and hundreds of hours of use.

I have the flexvolt dewalt, and I have for 6 or 7 years. It seems to have just as many beans as the classic 6 inch makita, maybe more. It definitely could use a longer run time somehow but it just goes and does whatever you need as long as you have the batteries.

[@wynstonclark1644]

I’ve used the dewalt 60v grinder for the last 3-4 years damn near every day, it won’t die on you, makes insane power for a battery grinder option, and has no maintenance like brushes that a lot of corded grinders in its size require replacing. Hands down the most impressive and convenient power tool I keep as a specialty welder.

Some models that I would love to see tested are the corded, brushless angle grinders from dewalt and metabo hpt. Yes brushless, corded.

You're probably not going to see this comment but I have an interesting test scenario. The 18v dewalt nicad grinder runs at 6000rpm. This is actually desirable when running large wire wheels. If one uses an 18-20v adapter, does it cause the tool to produce more RPM and risk shredding the wire wheel ?

@torquetestchannel I have the multivolt 6” Metabo HPT g3615dvf (paddle switch) if you’d like to test if for the rankings lmk as it’s actually a good balance of power and runtime imo, it’s not gonna beat the flex volt 418 by any means but it is good but one weird thing is when used with the ax adapter it doesn’t have the electronic brake oddly also have you guys tested any of the flex tools with their new ac adapter? Wondering if theirs hamstrings tools and if so how? Power, or features like the mhpt brake etc just an idea

[@larion3296]

Have a few Bosch 125mm 18V grinders and the power is slightly disappointing. One was advertised as 700 watts and the others as 1000watts. But they are not as powerful as the corded with same wattage. Still, the 1000watt models are quite usable, even if they are more like 750 watts corded grinders. The corded Bosch Professional grinders, on the other hand, have worked well and are just as good or better than other brands. I am cutting a lot of concrete and replaced the Metabo 230mm 2200watt grinder with a Bosch 230mm 2400 watt grinder. Big difference: the Bosch grinder is lighter and stronger, vibrate less, and have a very good protection against throws that turns off the power. More expensive but well worth it.

[@27duuude1]

Bought myself a few tools for a welding project. The real needs were a 4.5" corded angle and a Die Grinder. Milwaukee was the first choice out of budget and the die grinder had to be harbor fried brand. No tungsten burrs at the store "stocking issue" so the expense on good burrs with a cheaper grinder is also a big factor surprisingly. 400 dollars for an overbuilt dremel ruled out the Milwaukee. One handing anything over 5" shouldn't really be used for more than paint or for long periods of vibration, 6" cutting wheels are rarely needed if you can get enough power to the location. Obviously it's great in the bush cutting out huge bars but even then you usually want a gas powered 10" anyway

[@clintdurbin5081]

Milwaukee guy here but Dewalt make a really great corded 4 1/2 “ rat tail grinder still using it today bought back in 19 and has been heavily used in fabrication and rust/ paint removal and concrete work it’s been a great tool.

Need to see the DCG460. DeWalt rates that at 2800 MWO, versus the 2300 MWO of the 418 and 440. And actually, let's see the 440 as well. It is a lower speed but higher torque version of the 418.

[@ForfeMac]

Having spent a lot of time behind a grinder, I can safely say that the single most important metric to me is vibration. Frankly, you shouldn't be bogging down the grinder anyways because you burn out your consumables faster, so I don't worry so much about the maximum wattage. Not saying you shouldn't be putting any pressure behind it, just that you shouldn't be leaning on with your whole body like I've seen practically every apprentice, and an embarrassing amount of journeymen, do. It's a lot easier on the body, too. That said, I'd like to see air grinders compared on this list. They're lighter and run cold, which is nice when you're working out in 100 degree sun scorched wastelands, and are still popular on a lot of industrial worksites.

[@jamesward5721]

On grinders, I have a Metabo corded that I don't drop, chuck about or abuse - it was spendy. I use it for precise stuff. For everyday stuff I use 2 Hikoki - Hitachi - machines.

I've got an ancient 7-inch rat-tail makita, a 4.5 "dong" makita and a cordless 5" milwaukee, and I end up reaching for the milwaukee for most small lop-off jobs, and the 12ah battery lasts (seemingly) forever. If I have a lot of material to remove, I always plug in, because the corded tools hog away material faster, and no battery swapping required. These newer grinders are pretty impressive though.

test the larger 9 inch grinders next

[@falcordamascus4420]

Love this stuff you guys do ! Wha about Fein tools ? German , not sure if they do cordless , but our local welding shop really seems to dig the corded grinders. Cheers!

[@TheJensss]

A video idea could be to test some European corded tools made for 220v and compare them to US tools and see how much power you are losing with 110v

[@macattack1392]

When will u be testing the new matco stubby 1/2 air impact? Call it the raptor, says 1200ft lbs. 850 working & Any clue on the new 18v snapon stubby 3/8 impact. Says 500ft lbs if I recall. (I don't remember the working torque max)

[@Zissou42]

Runtime or total revolutions doesn't really make sense if they are operating at different speeds. Area under the curve (with the speed square rooted) would make more sense.

[@toolscientist]

Total revolutions is the area under the curve of RPM vs time. It might not be salvageable anyway as the higher RPM tools are wasting more of their energy driving their cooling fans. Per the fan affinity laws, power increases with RPM^3. On top of that, 200W is very low for a 1,300W tool (Dewalt), so it will be well below peak efficency. But a 780W tool (Bosch) will be near its peak efficiency at 200W.

18 volt just isnt enough for grinders imo, its too hard on the batteries. They overheat before going flat

[@FranciscoJavier-l5q]

Can you compare metabo hot 36 volts please

[@jackhinkle1401]

I would love to see you test the 7 inch cordless dewalt and the brand new 9in

[@charlesking678]

Can you do a vibration test for sds and sds max drills? They all work well, but some of them can really jar your insides loose and make drilling or chipping miserable.

[@jtreadwell6197]

Please review the Milwaukee 2666-21b kit from Home Depot. It’s a brushless high torque (non fuel) with a battery. $250 right now. Wondering if the hammer is the same as the faulty 2767 b’s that they released and shut down.

[@slingin_tires]

Very good test, curious how much longer the 4/12amp battery would last on the DCG418? Maybe you can test the DCF500 next vs the milwaukee high speed ratchets on the gauntlet?

[@PeterTrimboli]

You guys should test dremels (rotary tools) I'm curious to see how good the cordless are vs the corded and which brand is best although I already assume it's dremel

[@ToolinAround2025]

I have a Foredom with a big external motor, much better than Dremel imo.

[@aco2518]

In which video did you test the Dewalt grinder that broke? I can't find it

[@yuu2gamer]

what about the corded makita with the SJS clutch? id like to see that clutch put ti test

[@OUTILSCLIPSQC]

I like seeing the watts output of those grinder and paired with their best batteries good job ttc

[@_P0tat07_]

Hey TTC, can you test Atlas Copco pneumatic die grinders? I would hope they’re top of the line considering the price tags. And can you check out the Snap-On 1HP pneumatic die grinders? I would be really interested to see how they compare against each other. I would actually like to see a bunch of Atlas Copco tools tested, but I can understand if that’s out of reach considering the prices. But I’d like to at least see a die grinder tested.

[@CorDawgYT]

The speed wobble might be an effect of the constant RPM motor driver in the DeWalt, cutting power at high frequency or something like that to prevent overspeed.

[@v8packard]

Milwaukee used to make a corded Magnum grinder, model 6154-20. I wonder how it would compare in your dyno. It was my favorite grinder for years.

[@MKD4Life19]

Need to test Flex tools grinder with their top battery!!

[@tylertaylor3173]

I have the Milwaukee and the dewalt. I found out the dewalt doesn’t like having a 9” wire cup. The cup doesn’t like the dewalt either I have never seen a cup turn into a disk/wheel. After about 10 minutes the dewalt gave up and had to switch back to 6” wire wheel.

[@hilariohernandez340]

DeWalt purposely leaves that slop in some of those tools. In the impacts, that slop allows the bit to drive smoother at imperfect angles, like a gyro self correcting. Also allows some shock.

[@TsunauticusIV]

Will we get to see you testing the 1” railway impact wrench from Milwaukee?

[@misterx243]

Could you test European corded grinders? So on a 230v 50hz outlet. Would be cool to see gow they do for the European viewers. And show the differences in electrical grid

[@Jessemarchant723]

Any chance of getting a makita 40v on? I just got the the GAG04Z and love it. I'm really curious how it compares
