PROBLEM TO BE SOLVED: To provide a tool holder capable of connecting a tool holder body to a tapered shank part regardless of size of outer diameter of the tool holder body, restricting effects of centrifugal force generated at the time of high speed rotation, and effectively getting elastic deformation of the tapered shank part. SOLUTION: This tool holder 1 is provided with the tapered shank part 10 that is hollow to be installed on a machine spindle 100, and the tool holder part 11 connectable to the tapered shank part 10. As a part of the tapered shank part 10 is inserted into the tool holder body 11, the tapered shank part 10 and the tool holder body 2 are connected to each other. |
