The locking device is formed by a locking sleeve, which has a lock toothing and is rotatably fixedly connected to the threaded ring and which is axially movable between a drilling configuration and a clamping configuration relative to the threaded ring and the clamping sleeve; the locking device is also formed by a mating toothing assigned to the chuck body.
