A motor-driven manual grinder (10), in particular an eccentric-plate grinder, has a work spindle (13) supported in the tool housing (11) and also has a grinding plate unit (15) that is driven and rotatable by the work spindle to execute an eccentric motion. The manual grinder (10) further has an annular first rolling face (28), extending together with the grinding plate unit (15) all the way around the eccentric axis (19), and an annular second rolling face (30), associated with the first, whose center axis extends coaxially to the central axis (17) of the work spindle (13), and on which the first rolling face (28) can roll. The second rolling face (30) is supported rotatably about its center axis. It is assigned a braking device (35), by means of which a rotation of the second rolling face (30) about its center axis can be selectively prevented for the forced-drive mode or enabled for the free-wheeling mode.
