The present invention is to increase the engaging strength of the connection member and the tool body without causing damage to the tool body and the punch. A mounting hole 16 having a recess 17 on the inner circumferential surface of the tool body (1) of a hard material the, cylindrical shape of the connecting member 2 of a metallic material having lower hardness than the tool body 1, the mounting part ( 21) is inserted, the mounting part 21 is connected to the plastic deformation of the outer peripheral surface is in close contact with the inner circumferential surface of the installation hole 16, the recess 17 and engaging the tool body by combining (1) to be expanded diameter member (2 ) it is joined and the recess 17 is inserted opposite the first wall (17a), a first wall (17a) toward the outer circumferential side along the insertion direction (facing F) side of the installation section 21 to the center line of the direction of the second has a wall surface (17b), a first wall (17a), the mounting hole 16 at a position intersecting with the inner peripheral surface of the installation hole 16 toward the inner side as facing the (F) side of the vertical a planar first inclination angle (α) forms for the (S) is, smaller than the second inclination angle forming second wall surface (17b) on the plane (S) at the intersecting position the inner peripheral surface of the installation hole (16) (β) being It can control.
