Abstract

PURPOSE:To improve the setting strength and rigidity of a tool head, by drawing and clamping it by means of a draw bolt inside a setting hole piercing a shank body through in an axial direction. CONSTITUTION:In this tool head fitted with a rapid tool exchange mechanism, a draw bolt 5 is pulled by rotation of a sliding nut 7, and its detachable operation takes place by a head 4 existing inside a bag groove 14 of a cutter head 3. In this case, the draw bolt 5 is made contact with a key block 9 with a machined surface of the head 4 slidden. Therefore, a degree of setting accuracy and rigidity in the cutter head is raised up and the rate of operation is thus improved.
