Claim:
1. An indexable cutting insert, comprising: a top surface; a bottom surface; first to fourth side surfaces extending between the top surface and the bottom surface; and a screw hole passing through the top surface and the bottom surface, wherein the top surface includes a mounting surface comprising a flat surface, and the top surface and the bottom surface are rotationally symmetric with each other, wherein a first cutting edge is formed at a junction between the top surface and the first and second side surfaces, the first and second side surfaces being adjacent to each other, wherein a second cutting edge is formed at a junction between the bottom surface and the third and fourth side surfaces, the third and fourth side surfaces being adjacent to each other, and the second cutting edge being diagonally opposite the first cutting edge, wherein a first non-cutting edge is formed at a junction between the top surface and the third and fourth side surfaces, the third and fourth side surfaces being adjacent to each other, and wherein the first and second side surfaces form an acute angle with a plane containing the flat mounting surface of the top surface, and the third and fourth side surfaces form an obtuse angle with the plane containing the flat mounting surface of the top surface.
