Abstract
A cutting tool for improved material removal efficiency over a relatively wide mid range of typically used feed rates is disclosed. In a preferred form of an indexable polygonal cutting insert, a first cylindrical chip control groove of uniform width extends from a cutting edge at each side of the polygon and terminates inwardly from the edge in a second cylindrical chip control groove having a cross section of larger radius but of lesser depth than that of the first chip control groove. The second groove has its largest width at a point substantially midway between adjacent cutting corners of the polygon and diminishes to zero width at each corner of the polygon leaving a web of insert material running along the bisector of each corner angle, thereby providing adequate insert body support for enabling use of the disclosed chip control geometry on both sides of the insert. The cutting edge along each side of the polygon is arcuate with its lowest point relative to a major face of the insert being substantially at a mid point between each corner of the polygon.
