Claims

[Scope of utility model registration request]

a socket body that is attached at one end to the end of a spindle that rotates and moves in the axial direction, and a cutting tool is attached to a circular hole at the other end; a positioning ring that is fitted onto the outer circumferential thread of the socket body such that it can be screwed freely in the axial direction of the socket body; a lock nut that fixes the positioning ring to the socket body; a sliding ring that is fitted so as to be movable in a direction i and whose movable end is restricted by the outer periphery protrusion of the other end; a thrust bearing and a positioning member that are fitted to the outer periphery of the sliding ring so as to be relatively rotatable; A drill socket comprising: a workpiece contact ring whose relative movement in the axial direction with respect to the sliding ring is restrained by; and a compression spring installed between the positioning ring and the sliding ring along the outer periphery of the socket body.
