Patent ID: 7703560

Claim:
A cutting element comprising: a hard material body having an end surface symmetrical about a plane and a periphery defining a circumference, the end surface comprising a first portion extending to the periphery and a second canted portion extending to the periphery, wherein the first portion intersects the periphery along a first periphery line and wherein the second portion intersects the periphery along a second periphery line, wherein the second periphery line extends from one end of the first periphery line to another end of the first periphery line, wherein at least one of the first and second portions when viewed in cross-section along the plane is not linear; and an ultra hard material layer formed over the end surface having an exposed upper surface, said ultra hard material layer having a periphery and extending over both the first and second portions, wherein the ultra hard material layer comprises a thickness, wherein the thickness of the ultra hard material layer is maximum at a first location at the periphery of the ultra hard material layer at an intersection with the plane and wherein the thickness of the ultra hard material layer is minimum at a second location at the periphery of the ultra hard material layer at an intersection with the plane, wherein the second location is opposite the first location.
