More Information
Summary:A cutting element may include a body, a concave cutting face formed at a first end of the body, the cutting face including one or more cutting ridges adjacent a cutting tip that are raised above the concavity of the cutting face and having a length that is at least about 10% of a diameter of the cutting face. An edge is formed around a perimeter of the cutting face, and the edge has an edge angle defined between a tangent of the cutting face and a cylindrical side surface of the body, the edge angle being acute at the cutting tip and varying around the perimeter of the cutting face.
