Abstract
A power tool device, in particular a screwing and/or drilling device, including a drive unit for a rotational driving of a tool, in particular a drill or a screwdriver blade. The power tool device is adapted to detect at least one drive variable (AG) during the rotational driving of the tool, in which the drive variable (AG) is the torque acting on the tool and/or a drive variable associated with this torque, for example an electrical drive variable of the drive unit. The power tool device is adapted to determine a change criterion during the rotational driving of the tool on the basis of the at least one detected drive variable (AG) and to change the rotational driving of the tool in response to the detected drive variable (AG) satisfying the change criterion.
