Cutting element with canted interface surface and bit body incorporating the same

A cutting element comprising:

• a hard material body having an end surface symmetrical about a first 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 second portion extends at an angle relative to the first portion, wherein the first portion intersects the second portion along a non-linear boundary line defined across the end surface, 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 extending along a second plane, wherein the second periphery line extends from one end of the first periphery line to another end of the first periphery line;
• 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 first 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 first plane, wherein the second location is opposite the first location.

A bit comprising:

• a body;
• and
• a cutting element mounted on the body, the 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 portion extending to the periphery, wherein the second portion extends at an angle relative to the first portion, 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 the first portion when viewed in cross-section along the plane includes a continuous curving portion, 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.
