ABSTRACT:
A cutting insert for a cutting tool includes a cutting edge having a concave portion and a rear portion. The concave portion is disposed in the plane of one side surface of the insert and engages a workpiece in advance of the rear portion of the cutting edge. The latter extends from a radially outer end of the convex portion and has components directed radially outwardly, longitudinally rearwardly and toward the opposite side surface of the insert. The rear portion sequentially engages the workpiece to reduce the amount of vibration of the tool.
