Abstract: 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.

Abstract: A planer-type face milling machine for processing wood having a drive motor that is coupled to a work spindle, which supports, on a free end, a milling head, which on its front side supports cutting edges, the milling head being configured particularly as a disk-shaped body, running parallel to the workpiece surface, the milling cutting edges being supported by a cutter, particularly a planar one, furnished with main and secondary cutting edges, and removably arranged on the milling head, is configured as a particularly effective and-tool machine in that the planer-type face milling machine is correspondingly small and light and has a housing having a handle, the milling head supporting a cutter without a main cutting edge and having only at least one secondary cutting edge.
