  • This source and the tools they sell quality
Functionality: This grinder is a steal of a deal instead of paying an extra $75+ for the same exact tool. I have bought several tools and batteries from this source in the past year and I have not seen any drop in quality or failure. I work in an commercial-industrial setting where this grinder can work 10 hour days and chugs strong highly recommend. ... show more

  • Seems great.
Great tool. I overheated one of the smaller models and cooked the internals. I haven't used this one as much, though it's definitely a more industrial tool. It is either on or off. Not a variable speed grinder.

  • Another Winner from Milwaukee Tools
This angle grinder is a quality, sturdy tool. The braking feature makes it much safer to operate.

  • Its a BEAST
This thing is a beast!!!!! It's a Milwaukee tool I don't have to say much. I will definitely recommend buying either a forged battery or one of those high output m18 batteries. I used one of those regular m18 xc batteries the grinder worked magic but the battery went down super quick but I think that's because it was a xc and not a high output or forged. overall I love this grinder ... show more
