摘要:
A cutting insert for grooving operations includes a central shank portion and a forward cutting head. The cutting head includes a front clearance surface having a main cutting edge at an upper end thereof. The clearance surface is non-planar. Rather, the clearance surface exhibits a curvature in order to strengthen the main cutting edge.
