A thread-cutting chuck for use with minimum amounts of lubrication includes an axially central lubricant channel for connecting an insert sleeve for reception of a collet chuck, especially a quick-change insert, which accommodates a screw tap provided with a longitudinal borehole, with a minimum lubrication source on the machine side, from which the lubricant is passed as an aerosol to the longitudinal borehole of the screw tap. An axially displaceable coolant pipe which brings about a direct connection with the longitudinal borehole of the screw tap is provided in the lubricant channel extending into the junction region leading into the insert sleeve. The coolant pipe extends in one piece continuously from the screw tap up to the lubricant supplying channel of the chuck shaft, and is mounted displaceably in the insert sleeve of the collet chuck, and due to the pressure of the aerosol acting on its inner end surface, is pressed, independently of the axial position of the screw tap, into an engagement position with an end of the screw top such that it is communicative with the longitudinal borehole of the screw tap.
