Great tool works perfectly

I needed a small footprint tool to cut bolts inside a 4″ wall. Not only did it work it didn’t even use 1/2 charge on 3 ah battery. There were 4 1/2″ bolts.

Best all around tool without being tethered to a wire. A must for a fabricator

very well balanced and stable. vibration is well regulated. even the noise level is lower compared to my corded ones. the guard can be rotated on the fly, very smart! only wish the big red could come up with a quick release mechanism like the oscillating tool. kinda expensive for what it is. but it is the big red. so suck it up and get used to it, I guess. no more cords to worry about, a major plus for a thing like this. nice!

Replaced an older NiCad DeWalt grinder with this one. Have only used it a couple of times but it has way more power and battery life (5.0 ah) than the old one.

Have owned this and other similar Milwaukee models for over a year now. Overall a pretty good tool. I’ve found the best service using the 12 amp-hour battery. Two keys to the use of this tool: blade/wheel selection in relation to material being worked and when cutting through the material the operators attention to keeping the wheel aligned in the cut. I typically use my tool for cutting/slicing thru the material and use a diamond edge wheel for durability. The diamond wheel works good for hard materials such as steel. But not as good as for soft materials such as aluminum, rubber, etc. which seem to bind and clog the wheel. I believe a fiber wheel to be better for soft materials, but the fiber wheel will not last as long as the diamond wheel.Regarding maintaining the wheel/cut alignment: it is critical maintain them the same. Any misalignment or binding will immediately overload the battery causing the tool to stop and you to have to restart the tool by releasing and resetting the on switch. Overall a good and durable tool just be innovative in trying different wheels on different materials if you want satisfactory results.
