This tool is probably as reliable and tough as the other Milwaukee tools I own. There is NO 6″ cutting wheel guard (Type 1). I called Milwaukee customer service and confirmed that they don’t have one for this. They expect you to put a 6″ cutting wheel on a grinder with just a type 27 guard and violate OSHA rules. What happened to being all about the professionals. This is not what I expected from Milwaukee. If you plan to cut metal buy the 4.5/5″ or the 7/9″ model as there is a type 1 guard available for these.

The MILWAUKEE M18 FUEL 4-1/2” – 6” Braking Grinder is another quality power tool from Milwaukee. There are many great features with this grinder. I like the spring-loaded adjustable guard. The guard has notches on its mounting plate which allows the operator to rotate the guard without tools to the most convenient position. The guard is sized for up to 6 inch grinding wheels. The new FIXTEC nut allows the operator to flip up a spring loaded ½ washer to tighten or loosen the nut that secures the grinding disc (A wrench is provided if the FIXTEC nut is too tight to loosen by hand).The paddle switch is easy to engage with gloves on and stays engaged even with slight hand movement while grinding. The braking feature works great and meets the 3 second stop criteria. No more waiting for the grinding wheel to quit spinning or touching the grinding wheel to the work surface to stop it so you can set down the tool.The tool bag is large enough to carry the grinder, battery, charger and the grinding wheels required for your job. With the 6XC high output battery you get the power of a corded grinder that will last all day long for most jobs.In your hands the grinder has a nice balance and is comfortable to hold and maneuver. The support handle can be mounted on the left or right side. I like not dealing with the power cord and having the same performance. I would definitely recommend this grinder to it DIY or professional user.

Tool is great. Runs strong and lasts a good while. Only issues I have is the guard rattles while running and the carry bag isn’t big enough for the tool once the battery and wheel are on

love the no key quick change thing. wondering why nobody else think of this. long overdue. all the oscillating tools got quick releases. love the flexible guard as well. it doesn’t guard all that much to be honest. but just being there gives me peace of mind. not very heavy with the battery attached and well balanced. not much vibration , day and night from my cheap corded ones: ryobi and harbour freight. but this baby costs four times plus some than the other two combined!

Amazing tool. Very powerful and tuff. Just what I’ve learned to expect from Mikwaukee.

Powerful wonderful for the quick little jobs where you just have to cut this little piece or grind this little spot. You can just do the job and move on without having to pull out extension cords then go through the hassle of having to put it all away. Not used to the brake don’t know how much power it takes and if it is worth it to save the time.

This is a powerful unit that makes cutting and grinding of metals as easy as cutting cheese. So much faster and easier than a hacksaw. And much more convenient than a corded grinder that restricts your use in areas without standard electricity. Can use 4-1/2 thru 6-inch accessories’ that are not included with this kit so you can purchase just what items are best suited for your needs. And no tools are required as this unit has a FIXTEC nut and tool-free guard adjustment so you have barely any downtime if needing to switch out different accessories. This Grinder with Paddle Switch has an extremely fast stopping brake of about 3 seconds that works perfectly. Nice handle that attaches and detaches from the body of the tool. And the 6.0 ah battery is unmatched in my opinion of other brands I have tried. Not to mention you can use this battery with almost any of the other Milwaukee power tools which I have quite a few and extremely satisfied with each and every one. And this kit has also a heavy-duty carrying bag with the Milwaukee logo a very nice part of this fantastic kit which I simple love and recommend as an exceptional cordless tool. I love it the more I get to use it. This is one of the best grinders on the market in my opinion and I think anyone using this Milwaukee tool will agree.

Milwaukee M18 Model 2980-20 angle grinder review. I already had a Milwaukee corded 4 ½” angle grinder (model 6141-30). When I got the chance to check out the brand new 2980-20, I jumped at it, because I’ve had great service out of the corded 6141.The new 2980-20 comes with two M18 high output 6 a/h batteries, but of course will work with any of the M18 batteries. Check out the photo below, I’ve got the newly released high output 3.0 installed (not included with the grinder kit) in the grinder along with a 4 ½” cutting wheel. Note that the 4 ½ guard doesn’t come with this kit; the kit comes with a 6” guard. You’ll not want to run a 4 ½” wheel with the 6” guard, it isn’t safe. Pick up a 4 ½” guard – they’re easy to swap in and out. The new 3.0 battery has no problems running the grinder, but of course the 6 a/h included batteries last much longer. The 3.0 battery does make for a lighter, smaller package especially when combined with a 4 ½” wheel and guard.This model is a “paddle / no lock” switch (see photo below); I like it better than the “slide switch / lock” grinders; I feel I have more control over the tool. YMMV.The wheels/guards don’t require a wrench for changing out, but one is included with the kit anyway (in case you get one snugged down so tightly you need a little help in getting it free, which I tend to do). There’s no onboard storage for the wrench and, of course, since this is a cordless tool there’s no cord wrap attachment on the tool either.A ‘rapid’ M18/M12 charger is included, and this does seem to slice off maybe 1/3 of the charging times the first generation M18 chargers required to top off a battery. Of course, I’m a DIY’er, not a pro, so it’s unlikely I’ll ever deplete both batteries in the course of one day. Still, it’s nice to have a spare.The included contractor’s bag has rings for using a shoulder strap, but no strap was included in the kit. It’s a standard Milwaukee bag, no inside pockets and a single zipper. Well made.The unit comes with a very fast stop function – release the paddle and everything grinds to a halt in under 3 seconds. Nice safety feature that – and, speaking of safety, you’ll want face (not just eye) protection, hearing protection, and proper clothing when using this little beast. Wheels do break, work pieces do shatter, and it’s good to be protected. This tool isn’t particularly noisy as grinders go, but ear protection would be wise. Seriously – read the manual on this one, you may save yourself an injury.I use the tool more frequently as a cut-off tool than as a grinder (although there are projects where I’ll use it as a grinder too). With the proper blade this thing does yeoman’s work, it just plain flat slices and dices. While I’ve enjoyed having the older 6141, not having to deal with a cord is liberating. The 6141 has been relegated to the basement shop (where power outlets are abundant) and this new M18 2980-20 has been given pride of place in the garage. I had a metal flower trellis that needed removal and just being able to grab the M18 with a cutting wheel and get the thing cut down into pieces without having an extension cord run back to the house was great. Warranty – 5 years on tool, 3 years on battery, with a 90-day return policy from Home Depot.Build quality – excellent.Ergonomics – excellent.HTHRegards,Jim

Not only is this high capacity grinder awesome but as powerful as any corded grinder. It works perfect cutting steel, welding prep, and metal studs. The grinder does not heat up when in use, the side handle has an anti vibration system, and a built in tool free guard adjustment, no more screw drivers for adjustments. The high output XC6.0 battery comes with a rapid charger, a real plus. This grinder is durable and seems to be built to last. In my opinion the M18-tools are the best for every trade, I have many and use them all.

This grinder arrived well packaged and undamaged. Inside was the grinder, battery, charger, grinding guard, a locking tool, cushioned handle, and a nice canvas tool bag. First impression: SOLID & BEEFY! This tool is heavy duty and will grind anything you need. The auto stop works great. It is easy to change grinding wheels and with the large capacity battery, this tool can go for hours. The battery charged to full capacity in about 30 minutes. Quality is top notch. The only detractor is the weight. It is a two handed tool. Continued one handed operation is not possible unless you’re the hulk. Highly recommended.

Wow! This grinder is a beast. I will say using a cutting wheel XC5.0 was okay, however grinding wheel different story. Using a HD 8.0 or 12.0 rock on. I love the braking system this device has. The weight versus the smaller grinder is not bad at all. I would definitely purchase another one. I urge you to purchase one.

The grinder has plenty of power, the balance is nice and the switch is much improved over the older models. The braking feature is also nice so you can put the grinder down sooner after you get done grinding. As always,another home run for Milwaukee.
