Abstract

A drill has a housing, a motor mounted in the housing having a drive spindle, an output spindle rotationally driven by the drive spindle via a torque clutch. The torque clutch slips when the torque across the torque clutch exceeds a predetermined value. The predetermined value of the torque at which the torque clutch starts to slip is adjustable via a torque threshold adjustment mechanism. A sleeve is rotatably mounted on the output spindle. The drive spindle drives the sleeve via a gear system at a same rate and direction as the output spindle so that there is no relative rotation between the sleeve and output spindle when the torque clutch is not slipping and at a different rate and/or direction so that there is relative rotation between the sleeve and output spindle when the torque clutch is slipping.
