I’ve owned the smaller version of this grinder and absolutely love it. My only concern with it was the restriction of being limited to 4-1/2 inch blades. This grinder is a terrific flexible solution. Then they include an incredibly powerful battery upgrade as well. I love this tool. The battery will let you use this grinder all day long as I have done so on a paver project. Simply holding it, you will know it is quality throughout. Changing the blade takes less than a minute. Guard adjusting is even quicker. The 6.0 Ah battery is plenty of power for any project .Excellent instructions. Includes heavy canvas bag with plenty of extra room. Highly recommend.

The M18 FUEL line is the best out there in my opinion. I am a diesel mechanic and work on fuel trailers as well. I’m hard on my tools and I have a lot of this line in my tool box for the last 3 years and they take a beating everyday and keep taking a beating.

Best small grinder by far. Works like a 9” grinder.

This is a powerful grinder. And it definitely has a noticeable, yet modest power and rpm increase over the tried and true 5″ fuel grinder. There are a couple minor things that i noticed right away which i don’t like. One issue is the supplied retaining nut. it’s kind of a silly thing with a flip out tab which, I guess, is supposed to help you tighten it. unfortunately, that means the nut can only be used on way, and it doesn’t have any centering profile to help center the thicker grinding wheels. AND you still need grab the edges of the grinding disk to get enough leverage to torque the nut (or loosen it) anyway, so what use is that little tab? Fortunately that issue is easily rectified by just replacing it with a proper one from the fuel 5″ grinder. The other perplexing new design is the way the guard is retained and adjusted. It seems to work fine, but when the guard is removed it still leaves behind a floppy loose piece of metal, and spring. The old design worked just fine, and left no loose metal or springs on the grinder when removed like this new one. while these are very minor issues, their existence is confusing nonetheless. overall this appears to be a good quality and powerful grinder.

This angle grinder is just another example of quality power tools made by Milwaukee. It really does have power equal to its corded version. First thoughts on the angle grinder is that it is high quality and will be able to handle what you throw at. After using it a few times I can already tell that it is up to any task you need it to handle.Let me go into a few of the specs and features behind this angle grinder. First it can take discs from 4 1/2″ to 6″. Second it uses the Rapid Stop brake so all discs you use will stop in under 3 seconds. Specifically you cutting disc in 1.5 seconds, flap disc in 2 seconds and grinding disc in 2.5 seconds. The angle grinder uses a paddle switch with safety trigger built in to the paddle switch. There is no lock so you will have to hold the paddle switch during your entire use but that is another nice safety feature. The angle grinder also feature overload protection which is super nice so you don’t have to worry about wrecking your expensive investment. It also comes with an anti-vibration handle that does an excellent job.Some of the other features on this angle grinder that i really love are the tool free changes you can make to your setup. Change discs can be done tool free just need to use the lock nut that comes with the grinder as it has a tab on it to assist in loosening and tightening the disc in place. You also get a guard that can be changed tool free. The guard can also be completely removed tool free if you desire. The guard will lock in place in common guard placement positions. Additionally the anti-vibration secondary handle can be put on either side of the angle grinder without the use of a tool.Now let me cover the feel and weight of the angle grinder. The angle grinder is well balanced when using the 6.0 AH battery provided. I highly recommend that when using this grinder always go with the 6.0 battery. I tried a 12, 9, 6, 5, and 2 in the grinder and found the 6 to be the best balance. The 12 and 9 made the grinder back heavy, while the 5 and 2 made the grinder a little front heavy. With the 6.0 in place the grinder is super comfortable to hold and easy to use.Overall the performance of the grinder was pretty impressive. I used it to cut through a various metals and tiles and had no issues with it at all. The grinder easily handled rebar and porcelain tiles. The grinding was very easy and could get through whatever I needed it to do. I also used it to sand some wood and it really could eat through the wood.The other items included with this kit such as the contractor bag and rapid charger also make this a great set to get. Both are super nice to have especially the rapid charger with the 6.0 AH batteries.Overall I highly recommend this angle grinder.

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.

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.

Tons of power for a cordless tool, make sure to use a high output battery as this is definitely power hungry. Braking with a 6” blade in under 3 seconds is incredible, my old corded model would spin for a while after turning it off, nice safety features for a good price!
