The Latest Angle Grinders from Milwaukee, Hart & Makita Dyno'd v Harbor Freight

[@TorqueTestChannel]

Worry not, more brands currently on order and more to come still. When we build a new dyno it's always going to seem early on like we're leaving your favorite brand out until we buy it :)

[@FowlerAskew]

I'd be pretty interested to see the Metabo HPT grinders tested. Their standard 18V grinder is only like $100, and their 36V is $250, so if the performance and build quality delivers, I think it could be a good step up from the budget brands without costing quite as much as the more expensive brands.

[@CrashPro1]

Flex grinder speed adjustment is really useful when polishing since it can be less aggressive as nearing finish. Interesting if output potential is the same, but at least first cut-in is easier to control and more based on pressure applied. Also, wire wheels can really grab, especially on corners, so tames it down a bit. I think the speed adjustment has been very helpful!

[@ashkebora7262]

I'm betting they're just doing a "speed adjustment" via controlling some part of the power input. I don't remember my electronics enough to take a guess at what'd be easiest to produce the behavior, but motors don't take _that_ much current to keep at-speed. Not so surprising if a power limiter would produce both high unloaded RPM and similar max power output if it's just looking for spikes (or only able to see spikes) and some RPM range. It's an angle grinder, after all. Unloaded vs loaded has got to look crazy to the electronics regardless of RPM, and how big is the RPM range literally expected to be anyways? Something that'd mostly only soften the 'bite' of it sounds excellent. Speed adjustment sounds less useful and maybe just a bonus, but then my experience is _near_ bubkis.

[@PeregrineBF]

@@ashkebora7262 They're brushless motors, so they'd be controlling the input switching waveforms to the windings. It's the same principle as a variable frequency drive with a three-phase AC motor (because brushless "DC" motors are really multi-phase AC motors driven by switched DC).

[@ferrumignis]

@@ashkebora7262 They are brushless motors so controlling maximum speed is very easy, just a limit on the commutation rate of the three windings. This would provide the exact effect that TTC is seeing, limiting unloaded speed but not changing loaded speed.

[@ashkebora7262]

@@PeregrineBF Aren't BLDC's pretty good at controlling their speed? Not that they'd use a high quality controller for an angle grinder or anything, just opining on where in the electronics they've got the speed switch wired to. Seems like that part's got to be a bit simpler than a smart controller if RPM doesn't change much, unless it's focused entirely on power draw or acceleration. Lots of fun ways they could control performance if there's a computer chip around...

[@PeregrineBF]

@@ashkebora7262 BLDCs are great at speed control, because the speed depends entirely on the pulse sequence frequency. It's trivial to change speed with them, partly because they require a computerized controller.

[@chrissetter]

Variable speed is very important. I can only use variable speed grinders because almost all metal finishing pads (such as PFERD's non woven wool discs) have a low max rpm. It also allows a much more controlled finish on metal to avoid cupping and burning the surface while polishing. Otherwise, these expensive pads will immediately disintegrate. Don't forget, wire wheel discs also perform much better, fling less wire projectiles, and are much safer at a lower speed.

[@Houstonruss]

Yeah and your wire wheels get a huge benefit too!

i have the makita and love it. using the slower speed it helps discs and battery last longer as well as making a better job when using a wood carving or cutting disc or when using a sanding disc, buffing disc, wire wheel or eavan a grinding disc. it heats the metal up less making sharpening tools like mower blades, knives or slashers and certain brush cutter blades last longer and sharpen easyer

[@crandonborth]

This channel has become one of my favorite as you guys test everything so thoroughly and accurately.

[@JacobyStevens]

The only inaccurate thing is his pricing for Hercules and Milwaukee, his Herc setup is less than 200$ without deals but is listed as 283$ and the Milli would be 450$ without any deals, not 389$. But I'm sure Milli fanboys would rebel if he didn't put it at the top again 😄

[@mudrunner1]

I don't own a variable speed grinder, but I do have several grinders. The max RPM determines what I run on them. Cut off wheels go on the 11,000+ grinders. Flap disc and grinding disc go on the 9500 and wire brushes/wheels go on the 8000 grinders. If you have ever tried to used a wire cup on an 11k RPM grinder you will understand.

[@reaperreaper5098]

Speed adjustments really do just exist for lower RPM attachments and to an extent, polishing. I generally use wire wheels on a variable Flex grinder, and flap disks for paint removal, but serious grinding tends to go to my XGT grinders or DeWalt corded.

[@luisprieto4589]

XGT is the natural competitor given the battery tech. I don't know much about the XGT grinders, but the hammer drill and sawzall absolutely smokes Milwaukee and everyone else while running cooler and smoother

[@hammyzgod]

I've been running my dewalt flexvolt DCG418 like a dog for the last 3 years I always run it on 9ah or 12ah batteries as it just chews through the 6ah's to fast but honestly I always ran milwaukee until I got this beast and it was even more powerful than my corded makita which blew me away, another good thing about the 418 is that it came with a 6in gaurd as well as the 4,1/2in so it's perfect for doing wall chasing for leadwork. I'd live to see how this model holds up against the newest models guys and keep up the great content.

[@walz1414]

Love the speed adjustment on grinders. When you're using a 5" cup brush (the most unbalanced attachment I regularly use) it really cuts down on the free speed of the tool, which really cuts down on vibration and extends the brushes useful life. As the tool is going to slow down anyway when you load it up, not having it "runaway" when the tool is brought into the air or gets thrown off a work piece is nice.

[@michaelfralick2355]

Just got the M18. The speed adjustment was nice for a wire wheel that needed to spin a little slower, also nice for precision with a flappy

[@stefanvanzyl9090]

Been using my ryobi cordless brushless grinder XBG-115 for just about 8 months now, 3Ah battery packs. The speed reduction works great when cutting plastics, thin sheet metal and cable armouring - reduces heat, cuts cleaner and is easier to control. Though electrical installations is probably not the primary focus for big, heavy, powerful grinders!

[@hendo337]

I got the Hart a few months ago when it came out, it way nicer than the brushed version I also have, I got the Sawzall in both brushed and brushless, the 3/8 brushed impact, the 1/2" brushless impact, the brushless drill and driver, like 12 4a/h, 2 2a/h and 2 1.5 a/h batteries alone with the air compressor, lights, a fan, I went all outnon this Hart stuff since it's easiest for me to hit Walmart, I haven't regretted it, I like the Milwaukee stuff, I suppose I like to be extra Sloppy Mechanics and do things differently.

[@blackjackfabrication4043]

The Milwaukee Variable speed is a purpose built tool. It is more expensive than the standard Fuel 4-1/2” grinder. Yes you can do basic grinding with it but the point is for blending/polishing wheels not made to spin as fast as a standard grinder. I use them to polish stainless at a lower speed. Also I can feel a difference in power in the standard fuel grinder over the variable. Not sure if that’s true but it feels like it. But I don’t use the variable or the standard model to do much cutting. I have a 4-1/2”-6” model if I need to grind heavy and the grinder isn’t that much bigger.

[@EyeMWing]

Would be extremely interested in how the venerable Makita rat-tail corded 5" (9005BZ is current) stacks up, since it's basically the standard for fabricators who don't mind cords.

[@Comm0ut]

I bought my makita cordless on special with a free battery, and I use it way more than I thought I would. It's nice not having to drag out a cord to use an angle grinder on something quick, and the runtime doesn't bother me because if I'm doing something big I'll bite the bullet and dig out a cord.

Excellent video as always. I would sure like to see the other two TTI brands Ridgid and Ryobi. I expect judging by having identical parts on the outside that the Ryobi brushless is identical inside to Hart. The Ridgids R86042 (10600rpm) and R86047 (9000rpm) have a bigger more powerful motor, with noticeably better performance in my experience. I would also like to see Flex's variable speed grinder tested. I appreciate your pointing out that these variable speed models do not actually have a governor function which I personally find very beneficial. Some Kobalt selectable speed tools excel in this area! Which gives me hope for this Flex model. You guys are living my dream, love your videos, thanks again!

[@adampetten1009]

Sp glad you did this. I have a few Milwaukee grinders and wanted the 2888 for speed control but if it's not really controlling rpm then it's essentially useless.

[@joec9680]

I have a corded variable speed grinder mainly for use with wire wheels. Those quality HF wire wheels stay together much better at lower than normal grinder speeds. The lower you go with speed while maintaining a constant load = more heat from the motor. Yes that’s somewhat common sense but I say this because if I run it at “1” it’s lowest speed it will get so hot I have to give the thing a break in fear I’m going to melt down the motor. So I mostly use it at “3” it never gets to hot at that speed.

[@blendpinexus1416]

I've got the Milwaukee, i use the speed control for polishing, at full speed you burn up your sandpaper pad in no time. and also for core drilling with m14 diamond core drills, you need to go slow to make sure you start it off in the right place, and also again, you generate too much heat at higher speeds.

well im impressed with my Herc grease gun. blows out zerks on my tractor so it must be fairly stout and their 12A battery lasts FOREVER. also have the Herc reciprocating saw but havent used it yet. ill probably get their cordless grinder but normally cordless grinders dont handle what i put them thru.

I had a lot of old pipes and rebar to cut up and from what I read kzbin.infoUgkxPDBfLu68o58Aw85O_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.

would love to see the new(ish) Bosch Profactor grinder sometime Bosch PROFACTOR 18V SPITFIRE GWS18V

[@halflife82]

Great video! Thank you. Only complaint I have is, you should balance the grinding wheel and use that wheel to test the vibration across all grinders. All discs aren’t balanced, and depending if you put that heavy side on the heaviest side or even worst runout side of the tool arbour, it will amplify the vibration massively. I would use a balanced disc and do 4 readings with the grinder disc mounted 90* offset for each test and take the average. 👍

So this tells me that I should keep buying makita 5.0amp batteries thanks for the very helpful info, that saved me a lot!

[@ThePainkiller3666]

I own all Hercules and my buddy has all makita tools. Makita are usually heavier and put out more power but they go through batteries like crazy. I easily get double if not triple the runtime on a 5ah battery than he does, his batteries live on a charger. That being said his makita tools run cooler, after drilling ten 1/2in holes in concrete my Hercules brushless hammer drill is really hot but his brushless makita hasn't really warmed up yet. So we'll use my tools most of the day and switch his as a backup.

[@Tatarinfidel]

I think the speed adjustments are great for tile and wood grinding disks

[@bdykes7316]

Thank you for doing the vibration testing.

[@calvertschmued2920]

great work! please test corded 10-15amp 7 inch angle grinders, I'd love to see how they compare.

[@lonniehartke8823]

Please test Ridgid octane, and brushless. Thanks

[@sw86241996]

This Makita is old version , I own this one over 5 years, being very smooth for grinding and cutting I really like it, I also have corded Bosch 1500w .that is a beast if you cutting material for long time. Makita XGT released new one in Japan advise will be the most powerful cordless grinder yet. Not release in Australia for now

[@TorqueTestChannel]

It's the latest in the LXT line

[@sw86241996]

@@TorqueTestChannel I believe the same as mine, Makita did not develop 5 inch LXT grinder for many years. All XGT development now

Being a Milwaukee tool owner Gotta see flex and dewalt My m18 fuel stuff is pre pandemic and the kits and deals I got were less than half what the stuff costs today So no buyers remorse. They all work great But I’d seriously be looking at flex and dewalt today

[@ampaddiction]

Great video as always thanks for the hard work. I am primarily a dewalt guy although i do have a pretty large number of skil tools for my home use. I would like to see the skil brushless grinder tested. I will be glad to send you mine spare one to test if you would be interested in doing so. Let me know where to send it please.

[@phizc]

12:20 - A small mistake in the table: It says Runtime score is seconds/10, but the values are seconds/6, or minutes*10. e.g. Makikta 7.5 minutes, 75 points. (450 seconds)

[@mrsillyname]

you can use the slower speeds for polishing

[@elliotkane4443]

Been running my 54/60v Dewalt flexvolt 5" for 4yrs now. By far the best cordless grinder ive ever used, and thats from someone who has used fein, metabo, makita, bosch, milwaukee, hitachi, and probably more. 1000s of hrs. Power is 1 thing, vibration, Ergonomics (great dewalt handle and trigger). By comparison i had some heavy grinding last saturday to test out that milwaukee rapidstop. I thought it was a step up from their normal scabby, gutless grinders but i decided its a hunk of junk. That enormous milwaukee paddle switch is really terrible, hurts my hands to hold onto the thing for long, and the vibration is not great either. The Dewalt has more advantages, the relief-cut m14 thread and grinder nut both comes off/on easier and doesnt bind up nearly as often. As far as I'm concerned Dewalt is top dog in cordless grinders and has been for years.

[@LitheInLitotes]

Wrong. Milwaukee WON the FACT-BASED assessment. Anecdotes don't cut it.

[@jokly1264]

​@LitheInLitotes he's talking about the 60v grinder from dewalt which is a beast and has been out for years. No dewalt grinders have been tested by TTC yet.

[@engineer_alv]

@@jokly1264 that 60V DeWalt is no joke. I've seen it outperforming everything they've compared that one with. I'm just wondering what the runtime will be with let's say a 9Ah FV battery.

[@randallsensenig1075]

I agree! I have yet to use a better cordless grinder than the flexvolt, can’t wait to see it tested here!

[@N1rOx]

​@@engineer_alv the hikoki gen 1, beat the flexvolt gen 1 in torque over on the tools n stuff channel. A lot more compact too
