Claims

[Scope of utility model registration request]

It comprises a truncated conical tool shaft extending in the direction of the main axis of the machine tool and connecting a grip part for holding a cutting tool at its tip, and a pull stud for attaching a retractable collet type machine tool that protrudes from the rear end of the tool shaft. A tool holder characterized in that the inner peripheral surface of the tool shaft or pull stud is provided with a female threaded portion for mounting a draw screw fixed type machine tool.
