Abstract:
Disclosed is a cutting insert equipped with a polygonal-plate insert body (1) containing a pair of polygonal surfaces (2) and a multitude of lateral faces (3, 4). The insert body (1) is shaped so as to possess front-back inversion symmetry, a pair of level contact surfaces (8) are formed on each polygonal surface (2), and each contact surface (8) is capable of abutting one of a pair of surfaces to be contacted (19) formed on an underside (14) of an insert mount (13). Two imaginary extended surfaces extending from the pair of contact surfaces (8) intersect in a cross-sectional inverted V shape at an intersecting ridgeline (L). Among the lateral faces of the insert body (1), abutting parts are formed on the long lateral faces (3) which face one of the two directions in which the ridge line (L) extends, which can abut parts to be abutted formed on one wall surface (15) of the insert mount.
