Claims

[Scope of utility model registration request]

In a collet chuck that has a cylindrical hole for inserting a straight shank of a tool and has cuts in the longitudinal direction of the axis at equal intervals on the cylinder, a line in the axial direction that passes through any point on the circumference between each cut. A set screw hole is provided at a position symmetrical to the axis center line from the outer circumferential surface of the collet toward the axis center, and a protrusion provided at the tip of the screw screwed into the set screw hole protrudes from the inner circumferential surface of the collet chuck, A collet chuck in which the protruding ends are located on the same circumference including the flattened surface to prevent removal provided at the rear end of the straight shank.
