A method for operating a clutch in a power tool having an electric motor having an open-loop and closed-loop control device for closed-loop and open-loop control of motor power of the tool, and having a sensor, wherein the tool is operable in a first or second operating mode; in the first mode, the clutch is actuated after a predetermined time if a predetermined rotational speed threshold is undershot, and in the second mode, the clutch is actuated if a first predetermined motor current threshold value is exceeded. The method comprises setting the second mode; measuring the current of the motor; and reducing the motor rotational speed from a first rotational speed value to a second rotational speed value if a second predetermined current threshold value is exceeded, wherein a torque that can be generated by the tool is increased from a first torque value to a second torque value.
