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.

I’m looking into becoming a locksmith. I think one of these is gonna be my best friend.

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.

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.

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.

I would be curious to see how an average 220-240v corded grinder like we get in other countries would compare to these.

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 had the Milwaukee grinder but so glad I upgraded to Dewalt last year. Smokes it.

I would love to see you guys testing the old school Black & Decker 7/9” grinder 4075/4076, nicknamed “wildcat”. It’s in my opinion the peak of grinders.

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.

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.

I'd still love to see the M18 Flathead grinder and how it compares to the normal ones. Would even be willing to lend mine to see how it compares.

I've owned and used the dcg 418 for 4 years on a daily basis and still runs as new, honestly one of the best tools I've ever brought and has made my job so easy as a roofer weather its cutting through granite doing a wall chase for lead flashing, cutting roof tiles and slates it has halved my time and workload and couldn't live without it 👍.

The 60v Dewalt grinders are beasts...I have the older 60v model (and two of the 20v) and when I tested it, the only thing that could best it was the GIANT DWE4597 "4.9hp" 7" corded I have. Good to see the newer version is top of the charts :)

I recently did all the foundation and slab work for my sister's new house she's building. Our 14in gas cutoff saw took a crap on us so we ended up using my Dewalt 60v grinder to do all our rebar cutting lol. Thing is a beast. I've had it since they released it years ago. Would be cool to see you guys test their 7-9in 60v grinder too.

Finally! Been dying to know what that 60v dewalt grinder can do!

How about 7-9” grinders? Great episode!

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!

At my age, I value the low vibration and all around less fatigue a lot more than I used to.

You never ever disappoint, thank you kindly. I'd love to see a showdown between top of the line 230mm angle grinders from Fein (@2500 watts and Fein appear to have discontinued everything above 150mm), Bosch Professional (@2800 watts and brushless), Metabo (@2600 watts) and Makita (@2800 watts) To my knowledge, the only thing more powerful than those are high frequency grinders at 300 Hz.

Thanks! Love my flexvolt grinders!

Finally I’ve been telling everyone the dewalt 60 volt grinder couldn’t be beaten and you finally show it. And I can attest with many hours of daily use the dewalt flexvolt is also much much more ergonomic with the way the grip and trigger is designed

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

large angle grinders - who hasn't been waiting for this? 😄👍

Need the 9" 60v dewalt

Thanks for this, I was searching for a good tool for my night job, and this DeWalt looks great… I am a catalytic converter remover and speed is critical 😅

I appreciate the effort to get larger grinders tested. DeWalt Flexvolt tools are a beast everytime they're pitted against the competition and the DCG418 grinder is no exception. I'd like to see what Makita (XGT) and Metabo HPT Multivolt can do against Black & Yellow supremacy

Hopefully well see the big 9 in grinders run.

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.

You should make an angle grinder impact wrench

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.

I got 2 of the flexvolt Dewalt grinders, I love them, my corded angle grinders haven't been used in years.

we need a 9" cut off saw comparison.. Milwaukee, dewalt, and husqvarna all make one.

test the larger 9 inch grinders next

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.

love ttc, keep up the great work guys!!

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.

Been waiting for this video for two years. Thank you.

Waiting for 9 inch Dewalt to be tested! The 5/7 is great! I have flexvolt advantage and really like it

Just picked up the new Hilti Nuron 5", worth testing I am very impressed vs. my corded Milwaukee.

Another great video. Thank you.

My Dewalt DCG418 does better with 5 - 6 inch cup wire wheels than my 15 amp Bosch 9" grinder. The Dewalt just doesn't bog down except when the battery dies with 3 - 5 minutes of hard grinding time.

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.

I’d love to see you test some old 18v tools.

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

Nice video. Ridgid use to make a dual battery 7inch octane angle grinder which seemed pretty cool. They unfortunately don't anymore, but it can still be found on ebay and such rom time to time. AEG, at least in their Australian market, makes the same dual bettery grinder, but they have a 9 inch version and a 7 inch version (230mm and 180mm respectively)! They also have a corded 230mm/9inch version. Thanks for the video!

You should check out the Fein brushless corded grinders

Can you review the 3/4 in ridgid impact wrench

I own that DeWalt grinder and can confirm it is a beast..and im running the 6ah I can only imagine it with the 9ah. Great review🎉

Testing the good ol makita 9005b would be fun. BEAST of a 5" grinder.

This is one thing I do appreciate about this channel I love my dewalt stuff and while looking for a bigger grinder it’s nice knowing what I should aim for and I think I’m gonna stick with my dewalts 😅

And this is why I love my WEP-19 grinder.

Please test the metabo hpt 36v, it was tested by tools and stuff and looked great there

Some models that I would love to see tested are the corded, brushless angle grinders from dewalt and metabo hpt. Yes brushless, corded. I personally have been using the dewalt DWE43214NVS for well over a year as a welding student, and it is still going strong. Its safety features are also no slouch either. I am extremely curious to see how it compares to some o the metabos' corded models. You guys are an amazing resource for us all, and best of wishes to you all!

You should test Fein cordless and corded grinders.

Ive had the 418 for a few years after AvE did a breakdown on it. Fucking beast of a tool

Good video. I'm not sure as to ease of availability in the states, but it would be interesting to see Fein or Hilti on these tests.

That Milwaukee with the Forge is really impressive ! Not sure if you get Hilti over in the States but I'd love to see the comparison. Over here Hilti is Professional grade tools , you see it loads on construction sites .

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

Would like to see how the Milwaukee 6117-33D dial speed 5" corded grinder stacks up to Metabo and other dial speed grinders.

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

I've got that DeWalt, and that thing is an absolute beast! Screaming value for the performance, too.

2:18 DJ TTC spinning up discs

Hope you can get your hands on the new Bosch tabless battery packs soon

You guys should really test the cordless LTX lineup of Metabo i use the Powerdrill and Angle grinder on a daily base and those are by far the best cordless tools I ever owned I would think they would do great on the leaderboard

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)

Do you guys have a surface plate to check the flatness of the spindle nut on the Dewalt? If the thin disc is wobbly sounds like it might be some kind of deflection from the nut

I love my flexvolt grinder. Just a beast. You guys should test the new more powerful flexvolt grinder, I think it's a little bigger and even more power

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.

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

Dewalt has smoked competition the last two years.

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. Had to buy since my brother in laws company was using harbor freight Hercules that burned up in about 5-10 minutes of heavy use but Lowe’s was close by so my only option was dewalt at the time

Ive said on other videos that the flexvolt was the best from use in the field. The video and dyno to backup my claim. Now there is also a 7" flexvolt model that is rated as the same output but is basically geared different. More torque but less rpm. Depends wat you are doing for i guess which one is more ideal but for the most part this 6" is my main go to. Now there is also a 9" flexvolt model as well and i have that and that is obviously a beast too and it is a completely different body and larger.

I find myself more happy with my purchase of the DeWalt 20/60V system, almost every day! I discovered the power of the 9AH FlexVolt when I decided to buy one for my BWP152. What a beast of a system line! 🤘🏼👍🏼

Nice video !! Just dropping this here, we're using Walter 6" corded grinders at work and they're freaking good. I blew one two years ago during a shut down after 5 consecutive days of work in silica cutting down hundreds of feet long flat bars welded to steel conveyer frames. 😂

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

Power seems to always get weighted more than anything. Battery charge time should be included on the rankings imo. If the tool requires that battery for that power then the charge time should be the penalty. Yes, a sledge hammer will drive a 16 penny nail like nothing, but you won't do that all day. Yes Dewalt has power but the batteries are always the issue. Charge time, run time, durability.

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

i'd love to see the makita xgt or metabo hpt 36v put thru these tests.

Have you tested the Metabo HPT DV3615DVF? It’s the 6 inch multi volt grinder. It’s very nice walk the line of power and runtime pretty well. I’d like to see it tested on here though especially the load tester

How does a corded Makita 5" 9005b grinder rank up? I have been using that for years while I have been a welder and love it..

It would be cool to test out the newest Hikoki grinder. Not sure if metabo hpt have updated yet, but they are available in Japan, Aus and NZ! My unscientific opinion is that it has great power to weight/form factor ratio.

Would be interested to see those vibration measurements with a calibrated balanced disc that you guys made like one made out of metal or something

Possible you can test framing nail gun with different gauges, what technology behind and what mechanism they use, what kind of power comes with. I am ridgid gun because of LSA but I am looking for concrete nailer see if this topic fit your channel.

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?

You can test the Dewalt DWE43240VS corded brushless 5 in. grinder. I have the similar model here in europe the DWE4357. The power is out this world 😅

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!

There nothing like eating lunch and watching TCC on a Friday😮‍💨

1900W refers to the 220-240v version, probably amazon copy/paste mistake.

Thanks for sharing

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

Which one is the deadliest?

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. Cheap as chips but good. Both corded. I love cordless tools, but grinders are tools you use all day - batteries don't do "all day" no matter what brand unless you are loaded & can afford many batteries. I ain't.

Now we need to see the new dewalt dcg460 2800watt advertised output.

can you the test einhell tools i want to see how good they are please

Thanks for posting this a few days after I bought a grinder 🤣

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.

Rigid make a duel battery 9 inch with rotating head?

Be interesting to see the efficiency test at 400 and 600W. DC motor efficiency tends to fall off a cliff below 20% load

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