While improving the bonding strength of the tool body and exert renewed the connection member, thereby enabling the mass production without causing a shortening of the life of the press member. Installation of the cylindrical shape of the connecting member (2) comprising a tool body (1A), the inner circumferential surface concave portion (16a) mounting holes (16) in, the hard material than the lower metal material hardness having a formed comprising a hard material portion 21 is inserted, the mounting part 21 is being engaged with and plastic deformation, the outer peripheral surface of the attaching portion 21 is in close contact with the inner peripheral surface of the installation hole 16, recess (16a) so that the expanded diameter, these the tool body (1A) and the connecting member (2) is joined head with interchangeable cutting tool, the inner periphery of the attaching portion 21, the connecting member (2) than the hardness is fixed is press-fit is higher diameter expansion member 4 and It is disposed portion 21 is expanded in diameter by plastic deformation member (4).
