Abstract
A cutting tool is provided which comprises a curved cutting edge at a nose, a pair of straight cutting edges between which the nose is located, and a chamfer extending along the curved cutting edge and the straight cutting edges so as to form a curved ridge at a junction of a portion of the chamfer extending along the curved cutting edge and a tool face. A portion of the chamfer increases in width from a junction of the curved cutting edge and each of the straight cutting edges to a midpoint of the curved cutting edge when observed in plan.
