Abstract: A method to control a power tool (1), especially a handheld core drilling machine, includes a drive (10) to drive a tool (30) and a control unit (40) for when a workpiece (W) is being processed. The method encompasses the following method steps: setting the rotational speed of the drive at a first value; measuring a first power consumption value for the drive; setting a threshold value for the power consumption of the drive; and increasing the rotational speed of the drive to a second value if the power consumption of the drive (10) exceeds the threshold value due to an increase in the drive load. The power tool includes a drive (10) to drive a tool (3) and a control unit (40) to control at least the rotational speed of the drive.

Abstract: According to one aspect of the application, a device for driving a fastening element into a substrate has an energy-transfer element for transferring energy to the fastening element. The energy-transfer element can move preferably between a starting position and a setting position, wherein the energy-transfer element is located, before a driving-in procedure, in the starting position and, after the driving-in procedure, in the setting position. According to another aspect of the application, the device comprises a mechanical-energy storage device for storing mechanical energy. The energy-transfer element is then suitable preferably for transferring energy from the mechanical-energy storage device to the fastening element.

Abstract: According to one aspect of the application, a tool for driving a fastening element into an underlying surface comprises an energy transmission element for transmitting energy to the fastening element. The energy transmission element is preferably movable between an initial position and a setting position, the energy transmission device being in the initial position before the driving process and in the setting position after the driving process. According to another aspect of the application, the tool comprises a mechanical energy accumulator for storing mechanical energy. The energy transmission element is then suitable particularly for transmitting energy from the mechanical energy accumulator to the fastening element.

Abstract: A multifunction handheld tool machine having an at least partially axially percussive tool receptacle (7), a safety coupling (8) disposed in the power line between the tool receptacle and an electrical motor (6), a hand-guided housing and an ATC safety module (1) with a rotational sensor (3) sensitive to an angular displacement. The ATC safety module (1) is connected to an axial displacement sensor (4) and, in the event of exceeding an axial limit value (13b), the binary control signal (5) is suppressed by the axial displacement.
