Abstract
A motor-driven machine tool, in particular a hand-held power tool () includes a rotatably driveable tool (), a drive shaft () which is driven by a drive unit (), and an output shaft () on which the tool () is mounted. It is possible to transfer the rotational motion of the drive shaft () via an eccentric coupling device () to the output shaft (). A mass-balancing device () provides for oscillation compensation and is operatively connected to at least one of the shafts () and implements a compensation motion counter to the eccentric coupling motion.
