- a tool spindle including a striking surface which is oriented substantially perpendicularly relative to an axial direction of the tool spindle;
- a striking mechanism configured to transfer rotational motion into a translatory striking motion, the striking mechanism including a striker which is configured to transfer the translatory striking motion to the striking surface of the tool spindle;
- and
- a planetary transmission having (i) at least one first planetary transmission stage which drives the striking mechanism, (ii) a second planetary transmission stage which drives at least the tool spindle, and (iii) a striking mechanism shut-off clutch,
- wherein the striking mechanism shut-off clutch is situated between the first planetary transmission stage and the second planetary transmission stage,
- wherein the tool spindle is configured to transfer an axial clutching force in at least one operating state to the striking mechanism shut-off clutch which at least one of opens the striking mechanism shut-off clutch or closes the striking mechanism shut-off clutch.
