A handheld power tool includes a housing in which a motor coupled to an outgoing axle defining an axial direction is arranged, a front gear unit at a front end thereof, a first handle portion and a second supporting handle structure arranged at the front end of the housing and extending in a direction parallel to the axial direction in order to allow a user to support the tool at the front gear, and a first switch and a second switch configured to control a supply of energy to the motor. The handheld power tool is configured to require the user of the power tool to simultaneously operate the first switch and the second switch in order for energy to be supplied to the motor, and the second switch is arranged at the second supporting handle structure.

Handheld power tool

A hand-held power tool includes an electrical motor unit which includes a stator and a rotor arranged concentrically outside the stator, wherein a heat pipe is arranged with a first end inside the stator, thermally connected to the stator, and a second end reaching outside of the stator and thermally connected to a cooling device having a heat sink for cooling the second end of the heat pipe. The heat pipe includes a phase changing fluid for transporting heat from the first end to the second end to be dissipated at the cooling device. A fan is arranged to provide a cooling air stream to the heat sink and the fan is arranged to provide a cooling air stream to the heat sink independently of an operation of the motor unit.

Cooling arrangement and method for power tool

A power tool including a motor and a pulse unit intermittently driving an output shaft, wherein the pulse unit includes a cylinder with an inner cavity arranged to withhold a hydraulic fluid, and an anvil located inside the inner cavity, the anvil being connected to the output shaft, wherein: at least one recess is arranged inside the inner cavity wherein at least one magnet is provided inside the recess; and the at least one recess is deeper than the at least one magnet such that a pocket is formed in the recess outside the magnet.

Power tool with pulse unit with a magnet for removing particles

An Impulse wrench includes: a housing, a motor with a stator and a rotor, an impulse unit including an output shaft, a power control unit connected to the motor, and a trigger supported on the housing and connected to the power control unit and arranged to selectively deliver signals to activate the power control unit, wherein the impulse unit including the output shaft is axially displaceable in relation to the housing. The trigger includes a sensor arranged to be activated and deliver signals in response to axial displacements of the impulse unit including the output shaft relative to the housing, and the power control unit is arranged to control the motor operation in response to signals received from said sensor.

Impulse wrench with push start feature

A power tool, which includes or is connectable to a computerized unit including a user interface, includes: a portable tool body supporting a motion sensor unit; and an activation unit by which the power tool may be set in two different modes, one production mode and one user interaction mode in which the power tool is configured to provide data from the motion sensor unit to interact with the user interface, such that a movement of the tool body is translated into an input to the user interface.
