Abstract: A drill chuck having a chuck body connectable to a drill spindle, in which clamping jaws are arranged in guide receptacles which run at an incline to the chuck axis and, for the purpose of opening and closing, are adjustable by a threaded ring arranged so as to be rotatable and axially immovable with respect to the chuck body. A locking device, which is made up of a coaxial circle of locking recesses and of at least one locking member, is engaged with the locking recesses under the force of a locking spring. A locking adjusting, is rotatable to a limited extent between end stops and whose rotation allows the locking member to be adjusted. A latching device forms two latching positions in the circumferential direction. A dampener is arranged between the adjusting sleeve and the component adjacent thereto radially to the inside.
