This grinder is the grinder Hammer

I decided, after some back and forth for me this Metabo grinder. He runs very quietly, without any arms hurt from the vibration. I use it now for about 2 years. Since an entire stairwell was ground and smaller and larger parts.
The only reason I gave 4 stars is that the dust filter like drops. That makes quite a lot of dirt.
A big plus is the fact that a vacuum cleaner can be connected directly. (Bosch appliances need an adapter ..)
Would I buy!
