Abstract

A motor-driven machine tool (1) with a tool that can be rotatably driven comprises a drive shaft (5) and a tool shaft (6) on which the tool is received, the rotational movement of the drive shaft being transmissible onto the tool shaft via a coupling device (8). The drive shaft is rotatably received in pivot bearings (14, 15) in the housing of the machine tool, the coupling device acting upon the drive shaft in the portion between the two pivot bearings.
