Summary:The drill chuck comprises a base body (1) for being connected to a drive shaft, a casing (2) which can rotate with respect to said base body (1) and which defines a cavity (3) with a conical inner surface (4), jaws (5) arranged inside said cavity (3) such that they can move between open and closed positions, and a pusher (6) which can be moved axially (2) to push said jaws (5) against said conical inner surface (4). The pusher (6) has an outer thread (7) coupled to an inner thread (8) of the base body (1). The base body (1) and the casing have respective manual gripping surface elements (9, 10). The base body (1) has a gear ring (11) and the casing (2) has a radial key guide hole (12), or vice versa, for the coupling of an auxiliary key.
