The invention is based on a handheld power grinder, having a motor located in a housing ( 10 ), having a receiving flange ( 30 ) receiving a grinding tool ( 12 ), and having a motor-driven working shaft ( 16 ) as well as a balancing unit ( 22 ) that has at least one first and one second balancing mass ( 18, 20 ). It is proposed that the first balancing mass is embodied as a movable balancing mass ( 18 ), and the second balancing mass is embodied as a fixed balancing mass ( 20 ). A receiving flange for a grinding tool ( 12 ) and a balancing unit are also proposed.
