The invention is based on a hand power tool, in particular a disk-type sander, that comprises a motor (12) with a drive shaft (14) located in a housing, whereby the drive shaft (14)—by way of its side furthest from the motor (12)—is joined via an eccentric (18) with a sanding disk (16) that can walk around an annular, turnably supported means (20, 72) that is capable of being braked via braking means (22, 62).
