Abstract

A power grinder, in particular an oscillating grinder (10), includes a platelike grinding sheet holder (14), on whose working face (15) a grinding sheet (16) can be braced. Secure clamping of the grinding sheet and easy changing of the grinding sheet are provided, because the grinding sheet (16) can be inserted between the clamping jaw (22) and the grinding sheet holder (14)—counter to the elastic prestressing of the clamping jaw (22)—and is firmly held increasingly strongly counter to the insertion direction in proportion to the tensile force engaging it.
