Abstract
A motor-driven hand grinder formed as an eccentric disk grinder has a machine housing, a working spindle accommodated in the machine housing, a grinding disk unit which is driven to perform an eccentric movement and is rotatable, a ring-shaped first rolling surface rotatable together with the grinding disk unit about an eccentric axis, a ring-shaped second rolling surface having a central axis coaxial with a central axis of the working spindle and arranged so that the first rolling surface rolls on the second rolling surface, the second rolling surface being supported rotatably about its central axis, and a braking device associated with the second rolling surface for interrupting and releasing a rotation of the second rolling surface around its central axis.
