Abstract
An improved cutting element is disclosed. The cutting element has a disc-shaped body with a front face and a backside. A ring portion formed on the front face extends around a raised central protrusion in formation of a vertical ridge. A plurality of inwardly extending, straight radial slots are formed in the raised central portion and create a plurality of vertical ridge segments. A super-abrasive compound, such as synthetic diamond, is applied to the front face. To aid in stress relief, the ridges have curved corners.
