Abstract
A cutting insert simultaneously performs a plurality of operations such as roughing and finishing, or roughing and polishing. A roughing/finishing insert has a main cutting edge and a secondary cutting edge, both edges extending laterally relative to a direction of feed of the insert. The secondary cutting edge is disposed rearwardly of the main cutting edge and extends farther laterally outwardly than the main cutting edge by a distance which is substantially less than the lateral extent of the main cutting edge.
