Finally an angle grinder that won't beat you to death because you can easily control the speed, which means you can control how far the dirt goes. It even runs slow enough to be used for polishing. It has great torque and power at all speeds. A month earlier we'd bought a Bosh with similar capabilities, but it was quite awkward to use and significantly heavier, and the speed controller wasn't as easily accessible. Bosh also cost about twice as much, but we were so discouraged that we gave it away. This is a good buy. Much luck!
