摘要: A hand-held power tool, particularly hand-operated angle grinder has a device housing having a motor housing receiving an electric drive, a gear head arranged at one end of the motor housing and having a projecting drive spindle for a tool, and a handle arranged at another end of the motor housing and having a switch strip for switching the electric drive on and off, at least one of the handle and the gear head forming a rotatable housing part and being rotatable relative to the motor housing around a longitudinal axis of the motor housing. A manually actuated positioning device fixes the rotatable housing part in at least two different rotational positions, while the motor housing being provided with a central bearing neck, the rotatable housing part being provided with a rotating cross which is received on the bearing neck so as to be rotatable and secured against axial displacement, the positioning device being formed to cause a positive-locking engagement between the motor housing and the rotating cross.
