The chuck comprises: a body (14) having a through cavity (16) extending longitudinally along an axis (18); a bush for securing the tool (10), which is associated with a distal end of the body (14); a chamber arranged externally to the body (14) and divided by a sliding piston (36) into a first sub-chamber (38) communicating through a first radial channel (40) with the cavity (16) and into a second sub-chamber (42), from which a second radial channel (44) departs; and a cartridge arranged within a distal portion of the cavity (16), and within which a hollow space (60) open towards the distal end of the cartridge is defined. At least one first conduit (62) communicating with the cavity (16), and a second conduit (64) communicating with the second radial channel (44), lead into the hollow space (60). |
