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