1. A double-sided, indexable cutting insert for a milling cutter, comprising:

  • a first surface, a second surface opposite the first surface, a countersunk bore extending entirely through from the first surface to the second surface, a first pair of opposing side surfaces and a second pair of opposing side surfaces, each of the second pair of opposing side surfaces including a first planar facet surface and a second planar facet surface, the second planar facet surface being radially inward with respect to the first planar facet surface, the first surface including a seating surface defining a plane;

    a major cutting edge defined at an intersection between each of the first and second surfaces and each of the first pair of opposing side surfaces for a total of four (4) major cutting edges;

    a corner radius connecting each of the first pair of opposing side surfaces to each of the second pair of opposing side surfaces, and a tangency point delineating the corner radius from the first pair of opposing side surfaces;

    a minor cutting edge defined at an intersection between each of the first and second surfaces and a first planar facet surface of each of the second pair of opposing side surfaces for a total of four (4) minor cutting edges; and

    a first ramping cutting edge defined at the intersection between the second surface and the first planar facet surface, and a second ramping cutting edge defined at the intersection between the first surface and the second planar facet surface for a total of four (4) ramping cutting edges,wherein the cutting insert is capable of performing both milling and ramping cutting operations.
