PROBLEM TO BE SOLVED: To provide a float-free coupling method of coupling a tool insert of a rotating tool and a tool holder by fitting their shapes. SOLUTION: The coupling method of the tool insert of a rotary drive tool and the tool holder by fitting their shapes is characterized in that the tool holder has a receiving surface transmitting force or torque to the tool insert and that the tool insert is made of a harder material than that of the tool holder by sintering a compressed powder member. The sintered compressed powder member for the insert is used as a hob, and the receiving surface of the holder is punched or press-molded by using the hob. COPYRIGHT: (C)2007,JPO&INPIT |
