Wow! What a great tool!
Sharp tools are necessary whether you’re cutting down volunteer trees with a hatchet, chopping weeds in the garden with a hoe or putting an edge around flower beds with a flat point shovel. You can spend your whole day sharpening tools with a file or just spend a few minutes doing the job with this angle grinder. Believe me, the grinder is better! I carried some of my tools out to the barn to sharpen them after I got this grinder and a flap wheel. It took me less than 30 minutes to sharpen 3 axes, 1 machete, 1 hoe, 2 shovels, and 1 edger! Now those tools are as sharp as knives and the 18v battery was only ¼ down when I finished! I also cut a piece of steel conduit pipe with the cutting wheel just to see how well it worked. It cut it like it was butter! The paddle switch makes this grinder effortless to use even if you had to use it in a workplace all day. Plus I really like not having a cord in the way while I’m working. The Milwaukee One Key system helps with security (for every owner) and inventory control (for a business). It lets you use an app to locate and disable the tool if it is stolen (and it does more than just that). Be sure to read and follow the instruction book and also get some protective clothing (especially for your eyes)

As always Milwaukee tools delivers excellence. This is a powerful cordless grinder. What makes it great is that it is cordless and will hold a 4 1/2 or 5 inch grinding wheel. It's light weight yet heavy enough to handle the hardest of jobs. It has a brake on the wheel that stops it immediately and that's good. You don't want it still moving when you move it away from your work. Comes with two batteries and a charger. It's built to last and will as all Milwaukee tools do. Highly recommend this tool.

milwaukee fuel 5” brushless grinder with brake The grinder really does have the power of a corded grinder. This goes come at a cost though. At 7lbs with one of the included 6.0 high output batteries, it’s not the lightest grinder. For the portability it packs a lot of punch. The paddle button is easy to use and the safety is easy to release but still secure enough to not get accidentally turned on. The guard is easy to adjust by just pushing down on the button. The guard doesn’t rotate all the way flush with the tool though which can be annoying for tight spaces. The handle is nice to hold and is ambidextrous. The air vent by the battery does come with a removable filter to help keep metal shavings out of the tool. The rapid stop is a nice feature but doesn’t stop fast enough to avoid injury if the grinder slips. Using a cutting wheel I didn't get any drop in RPM when cutting through 16 gauge sheet metal I used in replacing the floor of my car. well balanced with the battery.

Top level quality all around on this grinder. Excellent Milwaukee grinder kit with two High Output 6.0 batteries make this a strong choice. My observations: • Kit includes the grinder/guard, 2 XC6.0 batteries, Rapid Charger, spanner wrench, and bag. • The grinder is easy to use and has all the safety features you want in the grinder. Rapidstop works. I compared times to what Milwaukee claimed and I found them to be accurate. About 1 second to full stop. Also has an electric clutch to prevent kickback. • The grinder is stable when using. Vibration was minimal. I felt in control of the grinder the entire time. • The handle is ergonomic and secure with a flared end for better grip. It can be moved to either side of the grinder depending on your application. • The guard can rotate as needed when pushing a small lever at the head of the grinder. Easy movement and stays in place when grinding, cutting, etc. • I like and prefer the paddle switch. It just feels better to me when handling it. The switch works well with no issues. • Some people overlook the vent clip. This will help keep the dust out of the grinder. Just make sure you occasionally remove and clean it. Only takes a couple of minutes. • One-Key is included and worth setting up within the Milwaukee One-Key app. You have the ability to track, monitor, manage, etc. your tools. Make sure you set this up and create an account. It’s easy and will only take about a couple of minutes. I even added my non-OneKey Milwaukee tools just so I could better inventory them and enter in Serial #’s etc. • The included batteries are their newer High Output batteries and will work on any M18 tool. The batteries are a nice upgrade and will run longer and cooler. This is an easy choice if you are looking for a grinder of this size. I recommend 100%.

The M18 cordless grinder feels like more power than my corded 9-Amp but the sneaky efficiency is making the big payoff for me. I suspect a big part of the power is those two REDLITHIUM High Output 6 AmpHr batteries that come with the Milwaukee model 2882-22 FUEL Brushless Cordless Braking Right Angle Grinder. Even though the 2882 turns 8,500 RPM versus my corded grinder's 12,000 RPM I think the 2882 has plenty of torque as I don't hear it slowing down while I'm grinding and grinding speed using the exact same type 27 wheel looked faster than the corded machine. I had a batch of rock-battered blades from the five foot mower and it literally only took a few minutes to knock out each blade with fresh edges. Maybe I should put in a masonry disk to see if I can do something about those rocks? And that brings us to that sneaky efficiency. More than just convenience of not having to drag out hundreds of feet of power cord and/or a generator for jobs that are far from power there is a serious time savings both not pulling out power and in not gathering it all up and putting it away again. On a big job that might not seem like much but I have a lot of short jobs, literally minutes or even seconds to dress an edge or cut off a tube to make something fit out in the field where hauling things back and forth takes massively longer than the actual grind work. Just grabbing the 2882 and knocking out the job and moving on really adds up the efficiency. I also very much like the RAPIDSTOP that halts the wheel in only a few seconds so it is safe to put the grinder down to start the next task instead of standing around holding while it spins itself down like my corded grinder. Every little thing really does add up with quality equipment. I haven't triggered the kickback protection or overload protection but am glad that they are there. I also haven't tried the tool tracking yet but it looks interesting. The only downside I have found is the charger sometimes emits a faint high pitch hissing noise that bothers my wife and our cats if they are near. With two high capacity batteries in the package I expect the charger will live in the shop where no one is likely to notice.

This is a well-made heavy-duty tool that has tremendous versatility for grinding and cutting metal. It can also be used with sanding discs. Two M18 red lithium high output 6.0 Ah batteries are included for plenty of run time, along with a M12/M18 charger. Both of my batteries arrived with a 25% charge – but only took about 40 minutes each to get fully charged. The brushless motor is rated at 11A and runs at 8,500 RPM for fast material removal. It has a brake function to stop the disc very quickly after the trigger is released for added safety. My grinder with battery and a sanding disc weighs about seven pounds which gives it the right amount of heft without being too heavy. The main grip and side handle are a grippy rubberized material that is comfortable to hold with or without gloves. I used it with a #60 grit sanding disc while doing some repair work on my wooden porch railings. The motor has plenty of power and quickly removed the material. The battery is still showing a full charge after about 15 minutes of on and off cycles. I am very satisfied with the quality and performance of this tool.

This Milwaukee tool is a BEAST! I am already thinking of what I can grind and I haven't even charged the batteries yet. This is my first Milwaukee made tool and to be honest, I wanted to discover what all the hype was. I wanted to know what was different from previous models and the first thing I noticed is the inclusion of the Milwaukee One Key which allows you to connect to your phone via Bluetooth when you install the app so you can track, manage and locate your One Key tools using Milwaukee's mesh network and the other is the increase to (2) 6Ah batteries versus previous models with 5Ah batteries. These new RedLithium High Output battery packs provide 50% more power with updated electronics and they run 50% cooler than the standard RedLithium battery. The included RapidCharge charges the High Output batteries 30% quicker than the standard charger. These new features along with the 11 Amp power of a corded tool using a brushless motor delivers up to 8,500 RPM of grinding power. They kept the electronic RapidStop which stops the abrasive wheel in under 2 seconds, the electronic clutch provides kick back control and still has 100% tool free accessory changes. I have to say that the first thing that comes to mind is the build quality. This thing oozes premium material and design. Made in Vietnam with 5 year tool and 3 year battery warranty. Great performance upgrades Milwaukee!

Waiting to get a charger in the battery for it.
I've received a four and a half by 5 inch grinder from my son as a Christmas gift. I'm waiting to get a deal on a battery and a battery charger for it so I can try it out. Thank you.

Milwaukee M18 for the win!
I bought wire wheel cups flapper wheels grinders and cutoffs. Been wanting this tool since last Christmas when I started my M18 journey with the 1/2" impact. I haven't even opened my pneumatic drawer in a while. Love FUEL tools!
