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 :)
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.
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.
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!
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.

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
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.
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.
A thing to mention is that Makita and (Hilti) are the only brands that I know that meassures the vibrations rrom their powertools. For us in the trades that means that the nerves in the hands last alot longer. And the tool.
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.
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.
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.
We're really happy to be able to bring runtime to these tools that dont advertise it, and i think this is basically the only way you could do it. A static digitally controlled load until dead.
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
Lol competitor? No you mean embarrassment 😂 skitkita need to add 22v to stay relevant if they were still only 18v they'd be replaced by Ryobi. There's a reason why the FREE Makita tool shelf was never chosen on belts and boxes for a whole year and replaced after Even dewank out does skitkita. Keep dreaming.

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.
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!
I would like to see the Kobalt, Rigid, DeWalt and Ryobi tested when you get a chance. I have the Kobalt, only paid $130 for it and I'm pleased with it.
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.
I have the lxt and my mate has the Milwaukee. You can use the makita all day, zero fatigue. The Milwaukee you use for 10 minutes and your hands know about it.
@@veridico84 I see them as Toyota, they make tools they do the job they're not high performing. When they moved production to china their 18v dropped off.
The XGT grinder is all around not a small jump up from any of the 18V options. XGT makes wired tools redundant in most cases - last I picked up my wired grinder was when I had loaned out the XGT one. The grinder is as powerful as totl wired and the battery lasts for quite a while.
I use the variable speed on the m18 2888 for control when prepping and finishing canoe stem bands/bash plates/reinforced high wear spots. They're made with kevlar felt and marine epoxy.
We got some DCG416VSB not to long ago to replace corded units that had burned up and I have to say I am impressed. We are running them with 9ah flexvolt batteries as we use those for other tools in the shop.
I need to see the Dewalt Flexvolt, with the different size flexvolt batteries! It's the reigning king, and needs to be put to the test against the young blood! Crazy how the budget brands have shown up
i've been building out my hercules tools, I think there's only one tool i paid full price for. there was a sale a few weeks ago you could get TWO of the ~~5ah~~ (8h! edited) batteries for 120 bucks. the rotating deals at HF really bring the cost down if you're not time sensitive on picking tools up. Also fairly impressed with all of the herc tools, very happy.
It was 2 8ah batteries for 120. Plus the nicer charger and the price comes to about $200. I'll stick to hercules and just wait for the deals to stock up.
At the moment you can get the herc, with a 5ah battery and a charger for $120. I wish my store had one in stock because I'd be jumping on that in a heartbeat
Best deal ever right now. $99 for the 8.0 amp battery and pretty much any tool you want included. I just grabbed 4 of the 8.0 amp batteries at $49 each, impact driver, hammer drill, angle grinder etc. all $49 ea. That 8.0 amp hour high output 21700 cell battery is a game changer for these tools, they all make 30-40% more power than with the 5.0 amp hour. Guess I'm just gonna sell my Milwaukee and pocket the $700 difference because Hercules is unbeatable right now.
I have been buying into the hercules 20v line and have been impressed so far. I bought the 3/8ths impact which has been great for lighter stuff and is small enough to get into places and will do my lug nuts with ease which is nice to keep in the car. I also managed to get 2 5ah batteries for 45 bucks a pop during a sale and also picked up the grinder and ocilating multi tool for 120 for both during the buy 2 tools for 120 and have been impressed with both so far. All in all for those 3 tools 2 5ah batteries and a charger I am in 315 dollars before tax looking at my reciepts so moral of the story if you don't need it now wait for a sale harbor frieght has them all the time and it is worth it for the garage mechanic and homeowner
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.
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!
Not a Makita guy at all but I would still take it over that HF. Almost every job site I’ve been on for the past 23 years tile guys are running those Makita grinder’s. And they beat the hell out of them. I also have a feeling you’re going to start to see huge gains with these Milwaukee tools when the stacked lithium drops. Another channel put a flex stacked lithium on the Milwaukee half-inch hammer drill using a 3-D printed battery adapter😂…, and it was absolutely ridiculous.
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. But if I'm off to the scrapyard to pull parts, or fixing something away from the shop, it's a godsend.
Kobalt 24v... Bought on memorial day special, tool was free with purchase of 4AH, 2AH, and charger for $149. Hard to beat. 5yr warranty tool, and 3yr battery. This was my second one, original still running strong.
I want to see the brushless Dewalt models tested! Bonus points if you test the base model and the flexvolt advantage and/or power detect models as well
I got my Hart brushless grinder tool only for sale for $80 and later found a 2 pack of 4ah batteries on sale for $90 with a free tool of my choice, I picked the palm sander. I've been pretty happy with it for at work, it's about a year old now and actually runs better as the gears wear into each other.
Lets see the Dewalt flexvolt grinder! That thing is a BEAST, they advertize 3hp. Decent battery life under heavy load too (probably because it just gets everything done so fast).
I suggested previously to include some 'Makita form factor' (for Makita battery) brushless grinders. I picked up a 3 speed BL for $32 that's quite decent. If one has Makita type batteries then the value cant be beat even if it may fall short of the big names. BTW a 21700 Makita 1p or 2p battery can be made from a kit, might be of interest for testing purposes
Just picked up a 2888 a month or so ago and love the variable speed! So much more versatile with sanding flap wheels or surface prep wheels and stuff. Would love to see the Bosch profactor and the Flex tested as well!
Ideally one would own the same brand for everything to save big money on batteries and chargers. It gets complicated when one brand excels at one thing a not so good at another. I'm impressed that a cordless grinder has respectable performance at all.
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.
@@thatrealba Interesting. What did you not like about it? So far I've done a lot with mine, including masonry grinding and cutting on my garage floor to patch it. I'm wondering where the limitations are.
@@JoeTheDIY it just seems underpowered and bogs easily, compared to what I was expecting. Maybe the 5 amp hour battery just doesn't provide enough juice. I dunno. But I'm sure they will throw one in the mix at some point.
@@thatrealba Gotcha. I usually try to let the tool do the work, but I can understand that. I usually use a 6ah HP battery. I blew through two and a half 1.5ah batteries sharpening two lawnmower blades. Higher ah and HP batteries seem to make a difference.
Please include the FLEXVOLT angle grinder. I have one that I've put through he ll and it still runs very strong. It behaves almost identically to my corded grinder and I would love to see how it dewalt stacks up. Thanks for your channel and all the amazing data you are collecting and sharing! Keep it up 😁
If your checking vibration, if like to see Flex's offering. I don't have the grinder but the reciprocating saw is mind blowing for vibration dampening.
I got the Herc grinder with the purchase of two 5ah batteries. Can't beat that with a 5 year in store warranty. I only use a grinder to cut concrete to install garage doors or when I'm playing around with my welder.
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.
something i've learned between this channel and long term reviews is that brands like rigid and hercules are pretty damn good if your not hemmering on the tool all day long.
I like that you had the tool vibration in the scoring. When you're using a tool for a long time nothing is more annoying than the tingling and itchy arms
At a place I worked we used a dynabrade 4 1/2” air grinders. Supposedly 20,000 rpm free speed and if you were good with a drill you could port it out and really turn the rpms and power up as well as noise. I’d love to see one tested but would prefer you not to test the porting option because once it’s ported, it’s ported. Those things could remove metal at an incredible rate though
Lower speed it definitely good for tile honing. And it's nice it holds the speed. You want lower free speed so it doesn't fling the velcro attached honing pad off, but maintain the speed when you lean into it.
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.
Would love to see Ridgid corded/cordless as they are all I use. Thanks guys! Would also love to see what a commercial air grinder would do on this setup!
Great review as usual and can't wait to see the xgt model tested :) btw if you open the Milwaukee grinder and see how it's motor is constructed you will know why it has such low efficiency :) Also on xgt model the speed regulation works much better, it uses feedback and regulates the output based on the load.
I have a Kobalt angle grinder that has been an absolute trooper for two years now. The only issue is it burns through Kobalt batteries VERY fast and slows down a lot under heavy grinding. My best friend died two days ago and I have his Milwaukee grinder now so I will be putting to work to honor him. I had been trying to buy that grinder from him for a long time… I didn’t want to get it this way though.
Every other trade marks is on the second categorie if not made xlock grinders.. jus save makita and bosch ,that is the nextr level on grinders .... i should be say bosch grinder is very safety , it turn down if fall, is stuck or some kick back... and brake motor is so quick .. under a second is stop ,so i love it
I think you should check out the flex with stacked lithium batteries & then maybe the metabo hpt & metabo Grider's. I know I would buy a metabo grinder over any other brand.
Test out the brushed cordless Milwaukee M18 grinder (Model # 2680-20), always goes on sale/is thrown in as a “free tool” when buying battery starter kits
Great review, thanks. Really looking to see how metabo(german ones) grinders compare to those! Also very interesting to see test of some powerful corded grinders.
I'm surprised you tested the Milwaukee 2888 this way and more surprised it did that well since it's a special purpose tool normally reserved for finer grained flap discs, specialized surface conditioning attachments, etc. Why didn't you test the 2880? I'd be interested in the results on that one considering how expensive the 2888 is in comparison.
I had a lot of old pipes and rebar to cut up and from what I read ruclips.net/user/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.
if you do a lot of metal polishing and such the variable speed really makes a difference. i used to speed all day with a older 5 "Milwaukee corded unit that had the variable speed but was a 13amp beast when needed. they discontinued it and never found one i was happy with after. i wish this m18 unit had been out the last time i bought one i would have nabbed it but i have made due with my other m18 grinders and doubt ill ever have to buy another one now
Low rpm is important for some accessories that aren't for angle grinders, but fit, like sanding discs. I'd use my grinder more if it wouldn't ruin discs as soon as they touch anything.
Milwaukee fuel 4 1/2-6”. I know it’s bigger but it does also use 4 1/2 accessories. Even if it can’t actually compete, it would be really cool just to see. It’s not very much bigger and a better buy IMO. The option to use 6” is awesome. Much quicker grinding and sanding and wire brushing as the contact patch is substantially larger. Thing is very hard to get it to bog down. Love that thing. I bet it would eat all these grinders lunch. It claims 13A corded power.
IDK where you're located for buying in-store, but you should test out Menards' Masterforce line, they have a whole suite of tools including a mid torque 500 lb-ft and also a 7.5Ah battery. They're made by Chervon who also make FLEX, EGO, and SKIL
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. 👍
We encourage anyone suggesting that to try and make a video on the subject quantifying those things on a new model. Typically you accelerate abuse to the point you can catch it on camera and it's just going to be disregarded as unrealistic use.
I'd be interested to see the DeWalt DCG405N 18v XR platform grinder, partly because I just bought one and am interested to see if I bought a pup, but also as it's a bit older now in the lineup but available for a reasonable price still....

Love the speed adjustment on grinders.

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.
LOVE the runtime test.Runtime is everything on angle grinders.
We're really happy to be able to bring runtime to these tools that dont advertise it, and i think this is basically the only way you could do it. A static digitally controlled load until dead.
nsijap yihsme jkusytn hyuytn😂😂😂😂
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
Lol competitor? No you mean embarrassment 😂 skitkita need to add 22v to stay relevant if they were still only 18v they'd be replaced by Ryobi.
There's a reason why the FREE Makita tool shelf was never chosen on belts and boxes for a whole year and replaced after Even dewank out does skitkita.
Keep dreaming.
@@johnthumble5154 you must be a young kid, thats never even had a power tool in your hand....keep drinking the koolaid junior, and playing your worthless video games... when you get a few years under your belt , come back and comment on a grown up subject...
Imagine thinking XGT tools are 22V higher than Milwaukee. Marketing really works
@@TorqueTestChannel lol 18+22 is 40.... Are you actually saying that 😂 lol what! Yes nominal voltage... Lol imagine thinking an 40v battery doesn't provide significantly more power than an 18v tool... When you have a dyno... Lol good one.
You know because Makita 18v tools regularly out performed Milwaukee...oh wait .. they don't.
I also love how you neglected every other point I made 😂
@@johnthumble5154 imagine getting your undies in a bunch for a tool. Lol, what's stopping Milwaukee from making a 40v? Speaking about Home Depot, why are their rental tools Makita? I mean, if they want to make max profit, they need the most dependable tool. Makitas are WAAAYYYY smoother, WAAAYYYY better build quality, and last WAAAYYYY longer than your caveman cheaply made tools.
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.
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!
I wanna see how you store all of the tools currently have on the shelf/you’ve tested and a shop tour!!!
Would love to see the Dewalt and Bosch options.
wow, that vibe data is super interesting!! That stuff is important to me, thanks for including it!
Definitely some surprises here
I would like to see the Kobalt, Rigid, DeWalt and Ryobi tested when you get a chance. I have the Kobalt, only paid $130 for it and I'm pleased with it.
We have to throw in the Dewalt. Both the 20v and the 60v with their 3ah/9ah flexvolt pack
Test all the different cordless dewalts, including the flat-head model hopefully
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.
I have the lxt and my mate has the Milwaukee. You can use the makita all day, zero fatigue. The Milwaukee you use for 10 minutes and your hands know about it.
Lol that's because it's garbage and gutless like most Makita tools 😂
@johnthumble5154 while there are a few makita tools that aren't the greatest, you're fairly far off the reality with your statement.
@@veridico84 not really... 18v Makita is regularly outperformes buy many tool brands including Ryobi
@@johnthumble5154 as I said, there are some makita tools that don't perform, but they generally are decent.
@@veridico84 I see them as Toyota, they make tools they do the job they're not high performing. When they moved production to china their 18v dropped off.
I’m curious of more Ryobi stuff and how their brushed vs brushless compare
The XGT grinder is all around not a small jump up from any of the 18V options.
XGT makes wired tools redundant in most cases - last I picked up my wired grinder was when I had loaned out the XGT one. The grinder is as powerful as totl wired and the battery lasts for quite a while.
Yep probably why he didnt test it 😂
Excellent idea to measure vibration. I find vibration to be a real concern when using oscillating tools, would be neat to see that measured.
Yeah my concern about durability isn't the tool, it's the hand that holds it!
I use the variable speed on the m18 2888 for control when prepping and finishing canoe stem bands/bash plates/reinforced high wear spots. They're made with kevlar felt and marine epoxy.
Im glad this channel is uploading more. Is the upload schedule going to change or, is it going to be every Friday with the occasional extra episode .
It's always every Friday, and sometimes a bonus day here and there.
I do love my 60V dewalt grinder! It is a bit bulky but comfortable to use and has great power.
We got some DCG416VSB not to long ago to replace corded units that had burned up and I have to say I am impressed. We are running them with 9ah flexvolt batteries as we use those for other tools in the shop.
I need to see the Dewalt Flexvolt, with the different size flexvolt batteries! It's the reigning king, and needs to be put to the test against the young blood!
Crazy how the budget brands have shown up
i've been building out my hercules tools, I think there's only one tool i paid full price for. there was a sale a few weeks ago you could get TWO of the ~~5ah~~ (8h! edited) batteries for 120 bucks. the rotating deals at HF really bring the cost down if you're not time sensitive on picking tools up. Also fairly impressed with all of the herc tools, very happy.
It was 2 8ah batteries for 120. Plus the nicer charger and the price comes to about $200. I'll stick to hercules and just wait for the deals to stock up.
@@boostlee5236 you are right my mistake! even better deal than what I said ;)
That's insane. Milwaukee's 2x 8ah xc8.0 is almost $400
At the moment you can get the herc, with a 5ah battery and a charger for $120. I wish my store had one in stock because I'd be jumping on that in a heartbeat
Best deal ever right now. $99 for the 8.0 amp battery and pretty much any tool you want included. I just grabbed 4 of the 8.0 amp batteries at $49 each, impact driver, hammer drill, angle grinder etc. all $49 ea. That 8.0 amp hour high output 21700 cell battery is a game changer for these tools, they all make 30-40% more power than with the 5.0 amp hour. Guess I'm just gonna sell my Milwaukee and pocket the $700 difference because Hercules is unbeatable right now.
Gotta say the Kobalt angle grinder but that is the only cordless I own. Never actually used it as an angle grinder, just with a cutoff wheel.
Which I think is $99 normally. I think it was a free tool when I purchased a 2ah and 4ah battery combo, $79 or $89 I think.
I have been buying into the hercules 20v line and have been impressed so far. I bought the 3/8ths impact which has been great for lighter stuff and is small enough to get into places and will do my lug nuts with ease which is nice to keep in the car. I also managed to get 2 5ah batteries for 45 bucks a pop during a sale and also picked up the grinder and ocilating multi tool for 120 for both during the buy 2 tools for 120 and have been impressed with both so far. All in all for those 3 tools 2 5ah batteries and a charger I am in 315 dollars before tax looking at my reciepts so moral of the story if you don't need it now wait for a sale harbor frieght has them all the time and it is worth it for the garage mechanic and homeowner
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.
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!
Not a Makita guy at all but I would still take it over that HF. Almost every job site I’ve been on for the past 23 years tile guys are running those Makita grinder’s. And they beat the hell out of them. I also have a feeling you’re going to start to see huge gains with these Milwaukee tools when the stacked lithium drops. Another channel put a flex stacked lithium on the Milwaukee half-inch hammer drill using a 3-D printed battery adapter😂…, and it was absolutely ridiculous.
I use the low speed on the Makita for coping trim with a flap disc. Works great.
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. But if I'm off to the scrapyard to pull parts, or fixing something away from the shop, it's a godsend.
my mates and i have had issues with the bearings on the motor spindle of milwauke battery grinders with the housing going out of round due to heat
We need to see the rest of the TTI offerings. Ryobi and Ridgid please. Dewalt and Flex would be interesting also.
Kobalt 24v... Bought on memorial day special, tool was free with purchase of 4AH, 2AH, and charger for $149. Hard to beat. 5yr warranty tool, and 3yr battery. This was my second one, original still running strong.
I want to see the brushless Dewalt models tested! Bonus points if you test the base model and the flexvolt advantage and/or power detect models as well
would love to see the new(ish) Bosch Profactor grinder sometime Bosch PROFACTOR 18V SPITFIRE GWS18V
Consider the Ridgid 18v grinder. Great content!
What about the dewalt cordelss grinder? I have always heard they have the best cordless grinders.
I got my Hart brushless grinder tool only for sale for $80 and later found a 2 pack of 4ah batteries on sale for $90 with a free tool of my choice, I picked the palm sander. I've been pretty happy with it for at work, it's about a year old now and actually runs better as the gears wear into each other.
Speed adjustment on grinders is used for sanding or buffing sometimes..
Lets see the Dewalt flexvolt grinder! That thing is a BEAST, they advertize 3hp. Decent battery life under heavy load too (probably because it just gets everything done so fast).
I suggested previously to include some 'Makita form factor' (for Makita battery) brushless grinders. I picked up a 3 speed BL for $32 that's quite decent. If one has Makita type batteries then the value cant be beat even if it may fall short of the big names.
BTW a 21700 Makita 1p or 2p battery can be made from a kit, might be of interest for testing purposes
Just picked up a 2888 a month or so ago and love the variable speed! So much more versatile with sanding flap wheels or surface prep wheels and stuff. Would love to see the Bosch profactor and the Flex tested as well!
Ideally one would own the same brand for everything to save big money on batteries and chargers. It gets complicated when one brand excels at one thing a not so good at another. I'm impressed that a cordless grinder has respectable performance at all.
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.
The only one I have is the Ryobi Brushless, so I'm curious how it compares. Think you could test one of those next time you go back to grinders?
I have that one too, and tbh, it's my only Ryobi that I'm disappointed in. And I'm pretty deep into the platform.
I'd also like to see the Ryobi tested.
@@thatrealba Interesting. What did you not like about it? So far I've done a lot with mine, including masonry grinding and cutting on my garage floor to patch it. I'm wondering where the limitations are.
@@JoeTheDIY it just seems underpowered and bogs easily, compared to what I was expecting. Maybe the 5 amp hour battery just doesn't provide enough juice. I dunno. But I'm sure they will throw one in the mix at some point.
@@thatrealba Gotcha. I usually try to let the tool do the work, but I can understand that. I usually use a 6ah HP battery. I blew through two and a half 1.5ah batteries sharpening two lawnmower blades. Higher ah and HP batteries seem to make a difference.
I have Makitas basic 40v grinder. Would love to see how it stacks against their lxt versions
Variable speed is also good for applications you may not think about when using a grinder. Carving and sanding wood for example
Please include the FLEXVOLT angle grinder. I have one that I've put through he ll and it still runs very strong. It behaves almost identically to my corded grinder and I would love to see how it dewalt stacks up.
Thanks for your channel and all the amazing data you are collecting and sharing! Keep it up 😁
If your checking vibration, if like to see Flex's offering. I don't have the grinder but the reciprocating saw is mind blowing for vibration dampening.
I got the Herc grinder with the purchase of two 5ah batteries. Can't beat that with a 5 year in store warranty. I only use a grinder to cut concrete to install garage doors or when I'm playing around with my welder.
Thank you for doing the vibration testing.
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.
something i've learned between this channel and long term reviews is that brands like rigid and hercules are pretty damn good if your not hemmering on the tool all day long.
Please test Ridgid octane, and brushless. Thanks
I like that you had the tool vibration in the scoring. When you're using a tool for a long time nothing is more annoying than the tingling and itchy arms
At a place I worked we used a dynabrade 4 1/2” air grinders. Supposedly 20,000 rpm free speed and if you were good with a drill you could port it out and really turn the rpms and power up as well as noise. I’d love to see one tested but would prefer you not to test the porting option because once it’s ported, it’s ported. Those things could remove metal at an incredible rate though
Lower speed it definitely good for tile honing. And it's nice it holds the speed. You want lower free speed so it doesn't fling the velcro attached honing pad off, but maintain the speed when you lean into it.
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.
Would love to see Ridgid corded/cordless as they are all I use. Thanks guys!
Would also love to see what a commercial air grinder would do on this setup!
TRY the FLEX PADDLE GRINDER have one and with the 3.5 STACKED LITHIUM It packs a punch
Great review as usual and can't wait to see the xgt model tested :) btw if you open the Milwaukee grinder and see how it's motor is constructed you will know why it has such low efficiency :)
Also on xgt model the speed regulation works much better, it uses feedback and regulates the output based on the load.
I have a Kobalt angle grinder that has been an absolute trooper for two years now. The only issue is it burns through Kobalt batteries VERY fast and slows down a lot under heavy grinding.
My best friend died two days ago and I have his Milwaukee grinder now so I will be putting to work to honor him. I had been trying to buy that grinder from him for a long time… I didn’t want to get it this way though.
I only use the variable speed for wire wheel brush and blendex drum .
great work! please test corded 10-15amp 7 inch angle grinders, I'd love to see how they compare.
Every other trade marks is on the second categorie if not made xlock grinders.. jus save makita and bosch ,that is the nextr level on grinders .... i should be say bosch grinder is very safety , it turn down if fall, is stuck or some kick back... and brake motor is so quick .. under a second is stop ,so i love it
I think you should check out the flex with stacked lithium batteries & then maybe the metabo hpt & metabo Grider's. I know I would buy a metabo grinder over any other brand.
Test out the brushed cordless Milwaukee M18 grinder (Model # 2680-20), always goes on sale/is thrown in as a “free tool” when buying battery starter kits
Great review, thanks. Really looking to see how metabo(german ones) grinders compare to those!
Also very interesting to see test of some powerful corded grinders.
I think the speed adjustments are great for tile and wood grinding disks
I'm surprised you tested the Milwaukee 2888 this way and more surprised it did that well since it's a special purpose tool normally reserved for finer grained flap discs, specialized surface conditioning attachments, etc.
Why didn't you test the 2880? I'd be interested in the results on that one considering how expensive the 2888 is in comparison.
I had a lot of old pipes and rebar to cut up and from what I read ruclips.net/user/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.
if you do a lot of metal polishing and such the variable speed really makes a difference. i used to speed all day with a older 5 "Milwaukee corded unit that had the variable speed but was a 13amp beast when needed. they discontinued it and never found one i was happy with after. i wish this m18 unit had been out the last time i bought one i would have nabbed it but i have made due with my other m18 grinders and doubt ill ever have to buy another one now
I definitely need to see the DeWalt DCG416B tested! With and withou the flex volt please!
Low rpm is important for some accessories that aren't for angle grinders, but fit, like sanding discs. I'd use my grinder more if it wouldn't ruin discs as soon as they touch anything.
Milwaukee fuel 4 1/2-6”. I know it’s bigger but it does also use 4 1/2 accessories. Even if it can’t actually compete, it would be really cool just to see. It’s not very much bigger and a better buy IMO. The option to use 6” is awesome. Much quicker grinding and sanding and wire brushing as the contact patch is substantially larger. Thing is very hard to get it to bog down. Love that thing. I bet it would eat all these grinders lunch. It claims 13A corded power.
you can use the slower speeds for polishing
I bought and returned but would love to see the Kobalt angle grinder ranked. They only make one so no need to specify a model.
Test the 60v flex volt dewalts it’s a beast
Looking forward to flex and makita 40v being included at some point
IDK where you're located for buying in-store, but you should test out Menards' Masterforce line, they have a whole suite of tools including a mid torque 500 lb-ft and also a 7.5Ah battery. They're made by Chervon who also make FLEX, EGO, and SKIL
IMO, the speed control is really just for polishing, sanding, buffing, and other low torque applications. It is quite useful.
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. 👍
Test for longevity and build quality.
That's what really matters.
Shiny numbers and peak performance is for marketing guys.
We encourage anyone suggesting that to try and make a video on the subject quantifying those things on a new model. Typically you accelerate abuse to the point you can catch it on camera and it's just going to be disregarded as unrealistic use.
I'd be interested to see the DeWalt DCG405N 18v XR platform grinder, partly because I just bought one and am interested to see if I bought a pup, but also as it's a bit older now in the lineup but available for a reasonable price still....
