I'll definitely buy again!
I do a bit of grinding as a fabricator and this grinder does the trick! Only one thing I could suggest would be to include a 4 ½" guard as well...I used one off an old grinder. An adjustable circumference guard would make switching size discs a breeze!....

      More battery life please.
      Alright, let's get the obvious out of the way. The tool is easily better than I expected. I love the power and speed + it feels great. Everyone in the shop loves not lugging air lines everywhere. But the largest battery I have is an 8 amp/hour and I find myself making two trips to the charger on longer work days. I can't deny the value and quality you get from this tool but until I can get a 12 a/h battery it looks like I'm just going to have to get used to stopping by the charger.

          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.

          Excellent kit. I love how it came in the heavy duty Milwaukee bag. Everything fits perfectly with room to spare for another tool. it comes with TWO XC6.0 batteries which is awesome. 6.0 will last you a long time compared to the 3.0s. The battery indicator is a great option to have. The attachable grip is very grip-y and helps stabilize everything. The touch and feel of everything is great and feels heavy duty. I love how strong it is and can see it being as strong as a corded one. I love Milwaukee and have over 15 hand and power tools, the oldest power tool being 14 years old and still working like day one!

          This is by far one of the best angle grinders I've owned. My primary grinder was a 4-1/2", 11 amp corded unit, but this one is much easier to use and outperforms it. It's slightly longer, but it is much more comfortable to use since the grip isn't as thick and the lack of a power cord automatically makes it easier to handle. The paddle switch is also very easy to use and the safety feels solid. Performance: it easily cuts through metal, especially if using a diamond blade. Cutting and grinding concrete is pretty effortless. Battery life: I really put it to the test one day cutting up old scrap metal before using it to working on concrete. Was able to do everything on one battery charge. I'm extremely satisfied with this grinder and highly recommend it if you're looking to replace a corded unit.

          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.

          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.

          The problem with corded grinders for me is I have to have AC power wherever I go. In most cases power is not close by and when it is I have to use an extension cord. Then you have to deal with a cord being pulled around the site and hope no one damages it. So I figured it’s time to get a battery powered grinder. I like the fact I can use 4.5” to 6” grinding wheels. My next job is re-tucking parts of a block foundation and brick chimney. I purchased a new diamond tuck point blade, Sku # 133817, I also purchased a masonry blade, 130238 and a metal cutting blade, 1000010438 for other uses. Several reasons I purchased Milwaukee, almost every battery tool I now have is Milwaukee and powered by the M18 fuel , so I have lots of backup batteries I can use. Milwaukee has a great reputation for quality tools. With a brushless motor it should last a long long time. The handle is padded for comfort. You have to push the lock-off button forward then squeeze the handle to start, this is a No-Lock trigger, which I like. It has a controlled start so you don’t get a “jerk” when you first pull the trigger. Rapid stop braking system, stops in less than 3 seconds. It has what they call a FIXTEC nut that has a tightening tab as a part of it so you don’t need a wrench to tighten, but a wrench is included in the kit. The 6” guard can easily be adjusted to 5 positions. On page 5 of the Operator’s Manual it says to only use the 6” guard with a 6” grinding wheel. You have to purchase a 4.5” guard separately for the 4.5” wheels. So I E-mailed Milwaukee on their web-site looking for a parts manual and the part number for the 4.5” guard, after the first day passed I decided to research myself. Found that a 6142-30, 4.5” corded grinder has a 4.5” guard. In the parts manual it looked like the guard was the correct one. So I went to the local Home Depot, because they had one in stock. Everything with the mounting is the same. So the Part # for that guard is 43-54-1200. I would think they would have included it in the kit. I ordered one from a local power tool company. After 3 days I received an email back from support that confirmed the number I ordered was correct. Haven’t received anything on the parts manual yet.
