Abstract
In a ceramic indexable cutting insert, an edge strengthening land extends rearwardly of a beveled cutting edge at an angle of from about 80 to about 100 degrees with respect to the peripheral side surface, and a grooved recess extents rearwardly and along the edge strengthening land to direct chips upwardly and outwardly away from the insert and the cutting edge. In one embodiment of the present invention intended for conditions of heavy depth of cut, enhanced edge strength is sacrificed and an edge strengthened land is not provided.
