摘要： A hand-held power tool which includes a gear housing with a gear for transmitting a torque, generated by a drive motor, to a spindle. The gear housing is exchangeably connectable to a tool attachment via an interface in such a way that a torque is transmitted from the spindle to an input spindle of the tool attachment. The interface includes a housing-side interface element with a flange ring, which is connected to the gear housing in a torsionally stiff manner. The housing-side interface element corresponds to a tool attachment-side interface element which includes a fastening ring that is rotatably supported on the tool attachment. The fastening ring is brought into engagement with the flange ring by a coupled rotatory and axial relative movement of the fastening ring with respect to the flange ring so that the fastening ring and the flange ring together form a bayonet-type connector.
