A hand-held power tool is provided which includes a clutch housing of a torque clutch, and a planetary gear, situated in a gear housing, for transmitting a torque which is generated by a drive motor to a drive shaft. The clutch housing cooperates with the planetary gear via a pressure plate. The pressure plate is displaced in the axial direction in order to disengage the torque clutch. The axial relative motion of the pressure plate causes an axial relative motion between a switching element and an associated optical sensor, via which the drive motor may be switched off.

The invention relates to a power drill, having a tool-clamping device that is fastened to a spindle shaft, having a torque clutch that includes an axially movable clutch plate on which an axial force is exerted by a plurality of compression springs that cooperate at least indirectly with an adjusting nut situated on a housing component. The compression springs are accommodated in first recesses embodied in the longitudinal direction of the housing component. A device for axially moving an axial bearing situated on the spindle shaft, is provided at the end of the spindle shaft oriented toward the tool-clamping device. According to the invention, on its side oriented toward the clutch plate, the device for axially moving the axial bearing has at least one actuating section that is situated in a second recess of the housing component and on the side oriented toward the clutch plate, cooperates with an adjusting element for the device.

A screw driving includes a housing, a motor, a spindle, a locator, a first detecting mechanism and a controller. The locator is mounted on a front end portion of the housing so as to be movable in a front-rear direction relative to the housing and configured to define a depth to which a screw is driven into a workpiece. The first detecting mechanism is configured to detect a position of the locator in the front-rear direction. The controller is configured to control driving of the motor. Rotational driving of the spindle in a forward direction is started in response to the spindle being pressed rearward, and the rotational driving of the spindle in the forward direction is stopped when the first detecting mechanism detects that the locator is disposed in a specified position rearward of a most forward position within a moving range of the locator.

A housing holding a stator has increased rigidity. A vibration driver drill includes a motor including a stator and a rotor rotatable relative to the stator, a gear case in front of the motor, a gear in the gear case to receive rotation of the rotor, an output shaft protruding frontward from the gear case to receive rotation from the gear, an integral cylindrical housing accommodating the motor and including a front portion with an opening and a rear portion closed, a gear case housing connected to the front portion of the integral cylindrical housing and including a right part and a left part and holding the gear case, and a grip housing extending downward from the gear case housing.

A power tool communication system including an external device including a first controller configured to transmit, via wireless communication to a power tool, configuration data including a work light duration parameter value and a work light brightness parameter value. The power tool includes a housing, a brushless direct current (DC) motor, a trigger, a work light, a wireless communication circuit configured to wirelessly communicate with the external device to receive the configuration data, and a second controller configured to control a work light duration of the work light based on the work light duration parameter value, and control a work light brightness of the work light based on the work light brightness parameter value.

A machine tool device includes at least one drive train unit including at least one gear shift element and which has at least two different rotational direction modes and at least two different speed modes, and with at least one switching unit arranged at least partially on the drive train unit. The switching unit comprises at least one actuating element, which is configured to select the rotational direction modes and the speed modes, and at least one switching element, which is configured to switch between the modes of rotation depending on a switching position of the actuating element.
