What a great tool. Adding to my collection of Bosch cordless tools.

  • Bosch is pretty good stuff
Style: Tool Only
I always wanted a battery powered instead of Bosch grinder so when my other brand device died I got the bosch. I'd imagine lots of good ones but I'm vested in bosch batteries already so that made the choice. the blade guard is a bit in the way though as it seems to cover a lot of the blade but it is rotatable so that helps. ... show more

  • Another tool in the arsenal.

Good balance, power and speed. The power button could latch more solidly as you have to keep your thumb at it during operation. Nice that battery is compatible with all my other Bosch tools.
