Abstract: The present invention is directed to an insertion tool (12) for a machine tool that has a hub (16) with at least one opening (42, 80) for insertion of a fastening means (40, 84), via which the hub (16) is clampable on a driving flange (22) of the machine tool connected to a drive shaft, the opening (42, 80) including a retaining region (54) and a releasing region (56), the releasing region (56) including a stop (66, 88) for limiting a release motion of the fastening means (40, 84). It is provided that the opening (42, 80) adjacent to the stop (66, 88) has a convex section (76, 90).

Abstract: A power tool, in particular a right-angle grinder, includes a motor and a gear, the motor and/or the gear embodied as a mountable function module. The gear is embodied as a mountable function module, with a gear input shaft supported in a gearbox, and the gear input shaft is fixed in the gearbox via at least one detent connection.

Abstract: A portable power tool includes a motor housing (22a, 22b, 22c, 22d, 68) and a housing cover (26a, 26b, 26c, 26d, 72) that is attached to the motor housing (22a, 22b, 22c, 22d, 68). The portable power tool includes insulation (44a, 44b, 44c, 44d, 70a, 70b) adjacent to the motor housing (22a, 22b, 22c, 22d, 68) and the housing cover (26a, 26b, 26c, 26d, 72), which are guided through a guide (50a, 50b, 50c, 50d, 52a, 52b, 52d, 92) in the direction toward the motor housing (22a, 22b, 22c, 22d, 68) and/or the housing cover (26a, 26b, 26c, 26d, 72).

Abstract: The invention relates to a hand power tool (2), having a housing (6), an electric motor accommodated in the housing (6), and a battery pack (4), releasably locked to the housing (6), for supplying the electric motor with electric current. At least one spring/damping element (38), mounted between the battery pack (4) and the housing (6) of the hand power tool (2), is provided, for damping vibration and -or eliminating a locking-dictated play between the battery pack (4) and the housing (6).
