A hand-held power tool includes a drive unit configured to drive an insertion tool in at least one non-percussive operating mode. The drive unit includes a percussion mechanism for percussive driving of the insertion tool in an associated percussion mode. The hand-held power tool further include a user guidance unit configured to be actuated by a user and a communication interface configured to communicate with the user guidance unit and to receive, from the user guidance unit, changeover instructions for changing over the drive unit between the at least one non-percussive operating mode and the associated percussion mode in an application-specific manner.

A handheld power tool is disclosed. The tool has a housing, a hammer mechanism and a torque coupling. The hammer mechanism includes a beater which is movably guided along the working axis in the guide tube. The guide tube is mounted in a suspension attached to the housing so that it is movable along the working axis. The torque coupling is mounted on the guide tube and is supported on the suspension in the impact direction. The guide tube is supported on the torque coupling in the impact direction. The guide tube may be shifted with respect to the housing in the impact direction such that the torque coupling is shifted relative to the housing through the guide tube in a positively guided manner.
