PURPOSE:To obtain the desired cutting width larger than the cutter width by forming one edge surface of an installation shaft connected with the rotary driving shaft of a machine tool to an installation surface forming an angle with respect to the axis center direction of the installation shaft and installing a cutter on the installation surface. CONSTITUTION:A cutter C used in working a casted product such as aluminium alloy casted article by a machine tool such as milling machine is equipped with an installation shaft 1 which is screwed at the top edge of the rotary shaft 2 of the machine tool, allowing the axis center to coincide, and the other edge side of the installation shaft 1 is formed to an installation surface 3 forming an angle (inclination angle of about 95 deg.) with respect to the axis center direction of the installation shaft. Each cutter body 4 of a well-known slab milling machine, side milling machine, zigzag cutter milling machine, etc., is positioned by inserting an installation hole 6 formed at the center part of the cutter body 4 onto a guide piece 6 projecting at the center part of the installation surface 3, and then fixed by flush bolts 7, ... Accordingly, the cutting width W1 larger than the cutter width W0 of the cutter body 4 can be obtained by the revolution of the cutter C.
