Abstract: A cutting insert having two opposing end surfaces, two identical opposing major side surfaces and two identical opposing minor side surfaces. Each end surface has four corners with two lowered corners and two raised corners, the two lowered corners being diagonally opposite each other, the two raised corners being diagonally opposite each other. The cutting insert also includes a major cutting edge formed at an intersection of each major edge and the end surface. A first section of the major cutting edge proximate the raised corner constitutes a leading end of the major cutting edge, and a second section of the major cutting edge proximate the lowered corner constitutes a trailing end of the major cutting edge. An angled margin only partially extends along the leading end of the major cutting edge and segments the major cutting edge.

Abstract: A cutting insert includes a polygonal body having an upper chip surface, a bottom surface and peripheral side surfaces extending between the upper chip surface and the bottom surface, the peripheral side surfaces intersecting the upper chip surface to form cutting edges therewith. A plurality of chip dividers are spaced apart about a perimeter of the upper chip surface to divide the chips produced by the cutting edges, each chip divider including a leading chip dividing portion adjacent to the cutting edge and extending generally upwardly from the cutting edge, the leading chip dividing portion having an elongated, rounded face. Adjacent chip dividers define a pocket such that the pockets are configured for promoting curling of chips produced by the cutting edges.

Abstract: An indexable cutting insert includes a rake face, a flank surface, a bottom surface, and a central aperture defined by an aperture side wall. The indexable cutting insert further has a mouth defined by a mouth surface. There is a primary coolant trough that has an aperture section in the side wall contained in the aperture side wall, a mouth section contained in the mouth surface, and a rake face section contained in the rake face. There is a radial angular coolant trough, which has an entrance end opening into a selected one of the primary coolant trough and the mouth. The radial angular coolant trough has an orientation wherein the central longitudinal axis thereof is generally perpendicular to a corresponding discrete cutting edge whereby during operation a coolant stream is directed toward the corresponding discrete cutting edge.
