摘要

A grinding tool, in particular a concrete grinding tool, comprising a drive spindle ( 1 ) driven by a motor in the working rotational direction (A) having a tool receptacle ( 7 ) at its free end. The tool receptacle ( 7 ) is provided with a flange ( 2 ) non-rotationally disposed on the drive spindle ( 1 ) and a nut ( 3 ) that can be threaded onto the free end ( 6 ) for clamping the tool ( 5 ) against the flange ( 2 ). The tool receptacle ( 7 ) further comprises an anti-rotation device ( 4 ) that prevents a rotation of the tool ( 5 ) relative to the drive spindle ( 1 ) in the working direction of rotation (A) of the drive spindle ( 1 ).
