A screwdriver is disclosed, comprising a removable depth stop which selectably either, when equipped with the depth stop, allows noiseless shutoff or, with the depth stop removed, allows torque-dependent shutoff, without any chattering occurring when the machine continues to run. To this end, an adjustable torque-dependent release clutch is combined with an entrainment clutch of known type, which is additionally preceded by a disconnect clutch, a locking means being provided in order to hold a throwout ring, which forms one of the two elements of the disconnect clutch, in a predetermined position under load. In this way, noiseless operation is ensured after release, both when working with the depth stop and in the case of torque-dependent shutoff, with the depth stop removed.
