Abstract

An exchangeable head cutting tool contains a tool main body made of a hard material and a connecting member made of a metal material having a lower hardness than the hard material. The tool main body and the connecting member are joined by inserting a cylindrical mounting portion of the connecting member into a mounting hole formed in the tool main body, and by plastically deforming the mounting portion so as to expand a diameter thereof, thereby bringing an outer peripheral surface of the mounting portion into close contact with the inner peripheral surface of the mounting hole and thus making the outer peripheral surface of the mounting portion engage with a concave portions of the tool main body. A diameter expanding member having a higher hardness than the connecting member is press-fitted into and fixed to an inner peripheral portion of the mounting portion.
