Abstract
A cutting insert mountable in an insert pocket of a milling cutter and capable of effectively absorbing a radially outward force during high speed machining and high ramp machining. The cutting insert has a top surface, a bottom surface, peripheral surfaces extending between the top and bottom surfaces, a mounting hole extending through the top surface and the bottom surface, a protrusion portion protruding from the bottom surface, and a pair of lower inclined abutment surfaces formed at opposite edges of the bottom surface. The lower inclined abutment surfaces are inclined in opposite directions toward a pair of opposing peripheral surfaces, outwardly and upwardly relative to the protrusion portion. The protrusion portion extends across the mounting hole and has a lateral surface facing radially outwardly of the milling cutter. The lateral surface selectively contacts or does not contact the insert pocket depending on a revolution speed of the milling cutter.
