ABSTRACT:
In a drilling machine, a rod-like stop member is mounted on the machine housing for limiting the extent to which a tool held in the machine can drill into a receiving surface. A handle lever, fitted on the housing, releasably locks the stop member in the desired position. The handle lever is pivotally mounted on the housing and has a specially shaped end surface which, in cooperation with a pressure plate, affords the locking engagement with the stop member. The locking engagement is provided by corrugated surfaces on the pressure plate and the stop member. The specially shaped end surface assures that the locked engagement cannot be released until a form-locking engagement between the pressure plate and stop member is overcome.
