摘要

The tool has a housing (10) accommodating a working spindle (13) with the tool (18) on its free end between a clamping flange (62) and nut (20) and a locking device for fixing the spindle against rotation. The clamping device (17) has a special nut containing the clamping flange in the form of a conventional SDS click nut whose change ring (19) can be operated by hand, especially tightened, when the working spindle is stationary to axially loosen the clamping flange and release the clamped tool.
