A rotary hammer includes a motor, a spindle coupled to the motor for receiving torque from the motor, a piston at least partially received within the spindle for reciprocation therein, a striker received within the spindle for reciprocation in response to reciprocation of the piston, and an anvil received within the spindle and positioned between the striker and a tool bit. The anvil imparts axial impacts to the tool bit in response to reciprocation of the striker. The rotary hammer also includes a synchronizing assembly operable in a first configuration in which the motor is drivably coupled to the piston for reciprocating the piston, and a second configuration in which the piston is decoupled from the motor. The rotary hammer further includes an actuator operable for switching the synchronizing assembly from the second configuration to the first configuration in response to depressing the tool bit against a workpiece.

A hand-held power tool, in particular an impact drill driver, has a gearbox assemblage, a hammer impact mechanism, and a tool spindle. The hammer impact mechanism includes a striker that at least partly surrounds the tool spindle in at least one plane.

A drill hammer and/or a chipper hammer device includes a hammer mechanism having a drive unit and a transmission unit. The transmission unit transmits a drive torque from a motor to the hammer mechanism. The transmission unit includes at least one planetary drive. A drive element of the drive unit is disposed on a transmission element of the planetary drive.

A hand-held power tool includes an output spindle and a user guidance unit configured to be actuated by a user. The hand-held power tool further includes a drive unit configured to rotationally drive the output spindle. The drive unit can be changed over between a first direction of rotation and a second direction of rotation in order to drive the output spindle in the first or second direction of rotation. The power tool further includes a communication interface configured to communicate with the user guidance unit. The communication interface is further configured to receive, from the user guidance unit, changeover instructions for changing over the drive unit between the first direction of rotation and the second direction of rotation in an application-specific manner.

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.

An axial bearing for reducing wear is provided in an overload clutch for arrangement between a drive unit and a power take-off unit of a hand-held power tool in order to enable decoupling of the drive unit from the power take-off unit in the hand-held power tool when a limit torque is exceeded.

A hand-held power tool includes a drive unit that has at least one gear-shift transmission which can shift at least between two different gear steps; a striking mechanism that can be activated for performing a striking mode is associated with the drive unit; a shifting unit is provided for shifting the gear-shift transmission between the at least two different gear steps and/or for activating/deactivating the striking mechanism, and a communication interface is provided for communicating with a user-actuated user guiding unit and is configured to receive shifting instructions from the user guiding unit in order for the transmission to shift in an application-specific manner between the two different gear steps and/or for the striking mechanism to be activated/deactivated.

A hammer drill comprises a drive mechanism including a spindle, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, and a hammer lockout mechanism adjustable between a first mode and a second mode. The hammer drill further comprises a clutch adjustable between a first state and a second state. The hammer drill further comprises a collar rotatably coupled to the housing and movable between a first rotational position in which the hammer lockout mechanism is in the first mode and the clutch is in the first state, a second rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the first state, and a third rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the second state.

A hand tool device has a tool spindle and a hammer mechanism which includes a hammer and at least one curve guide driving the hammer at least during a hammer drilling operation. The tool spindle has at least one bearing surface on which the hammer is movably supported in at least one operating state.

An impact tool includes a motor, a driving mechanism, and a vibration sensor. The driving mechanism is configured to perform a hammering operation of linearly driving a tool accessory along an impact-axis by power of the motor. The impact-axis extends in a front-rear direction of the impact tool. The vibration sensor is configured to detect vibrations. The vibration sensor is disposed such that the vibration sensor is capable of detecting vibrations of a first frequency among vibrations caused in the impact tool, and such that transmission of vibrations of a second frequency to the vibration sensor is suppressed. The vibrations of the first frequency result from the hammering operation. The second frequency is different from the first frequency.
