ック。The sleeve part of the chuck body has a tapered outer circumferential surface of a tool fitting sleeve integrally formed on the shank part, and a tightening device having an inner circumferential surface formed in a tapered shape corresponding to the tapered outer circumferential surface of this sleeve part. This is a roll lock milling chuck in which a nut is externally tightened through a group of two-dollon lances, and this sleeve section is elastically deformed to reduce its diameter, and the sleeve section is fitted inside and grips the shank section of a tool. In this step, a plurality of deep holes are formed at equal angles along the axis of the sleeve from the end surface inside the peripheral wall of the sleeve, and the connection between these deep holes and the tool fitting hole of the sleeve is made. A roll lock milling chuck characterized in that the inner circumference of the circumferential wall is divided into a plurality of parts in the circumferential direction by forming slit-shaped cut portions on the inner circumferential portion of the circumferential wall between them.
