Abstract

The tool has a crank drive with an axially rotatable crankshaft (10) supporting a connecting rod at a crankshaft journal (9). The crankshaft is coaxially hollow-formed, and is axially closed at both sides. A plug (15) is provided opposite to the crankshaft journal at an axial end of the crankshaft. A wall thickness (W) of the hollow crankshaft amounts to less than one-tenth of the assigned shaft diameter (D). An axial stopper (18) is attached to a bearing guide (17), and the crankshaft is radially tapered axially between two bearing guides.
