Abstract
A drilling chuck for operation on an impact drilling spindle, which can be subjected to tangential loading, with a chuck body, which is connected or connectable to the impact drilling spindle in which jaw guides are formed, which are arranged inclined to the chuck axis, in which clamping jaws are guided which can be adjusted by means of a threaded ring, with a clamping sleeve, which is coupled in a torque-transmitting manner to the threaded ring, and with a locking device, which is adjustable between a release configuration which enables a relative rotation of the threaded ring with respect to the chuck body, and a locking configuration which obstructs or prevents this relative rotation. The locking device is formed from a locking sleeve, which is essentially rotationally fixed but axially displaceable with respect to the chuck body, which locking sleeve comprises at least one locking member.
