Zusammenfassung:A method is disclosed for controlling a hand-held power tool, in particular a cut-off screwdriver, the hand-held power tool including a drive motor and a control unit. The method includes (i) setting an operating stage for controlling the drive motor by way of the control unit, wherein the operating stage includes a direction of rotation of the drive motor, a rotational speed of the drive motor, and a cut-off criterion, (ii) setting a rotational speed constancy of the rotational speed of the drive motor, (iii) operating the drive motor depending on set operating stage and/or the set rotational speed constancy, and (iv) braking the drive motor when the cut-off criterion is met.
