ダ。 An adjustment screw hole is formed following the tool insertion hole of the through hole in a tool holder that includes a shank part that can be attached to the main shaft, a collar part that continues to the shank part, and a cylindrical part that continues to the collar part and into which a cutting tool is inserted. The adjusting screw hole communicates with the operating screw hole from the outer periphery of the main body, and the adjusting screw hole houses the adjusting screw and the adjusting screw with threads on the inner and outer surfaces, and the adjusting screw is provided with the operating screw from the outer periphery for adjustment. A fine adjustment type tool holder characterized by being screwed so that it can come into contact with a contact surface, and by rotating a double adjustment screw using an operation screw, the protrusion length of the tool can be adjusted.
