ABSTRACT:
A substantially square throwaway insert can be used for perpendicular machining if a cutting tool on which the insert is mounted is rotated in either direction. All its four corners can be used as cutting edges. Each cutting edge protrudes outwardly toward the center thereof, as viewed from top of the insert. Also, each cutting edge recedes toward the center as viewed from side of the insert. The insert is mounted on a cutting tool with such an axial rake and a radial rake that each corner of the insert can machine a surface having substantially a right angle.
