摘要

In a cutting insert which has a top surface, a bottom surface and a side surface connecting them, in which a part of an intersecting ridge between the top surface and the side surface functions as a cutting edge, and in which in the side surface, a side surface portion adjacent to the intersecting ridge portion opposing the cutting edge intersects the top surface at an acute angle, a structure in which shifting hardly occurs even by cutting resistance applied to the cutting edge is provided. At least on a part of a bottom surface (3), an inclined surface (12) gradually approaching the top surface (2) with increasing distance from a side surface portion (4b) on a side opposite to a cutting edge (8) is formed. Since the cutting resistance applied to the cutting edge (8) is resolved into a force perpendicular to the inclined surface (12) and a force parallel thereto, a part of the cutting resistance acts on the side surface portion (4b). As a result, friction resistance between the side surface portion (4b) and the side surface (24) of an insert seat (22) becomes larger.
