Abstract:
A cutting element has a cutting face at an opposite axial end from a base, a side surface extending from the base to the cutting face, an edge formed at the intersection between the cutting face and the side surface, and an elongated protrusion formed at the cutting face and extending between opposite sides of the edge, wherein the elongated protrusion has a geometry including a border extending around a concave surface and sloped surfaces extending between the border and the edge, and wherein the concave surface has a major axis dimension measured between opposite sides of the border and a minor axis dimension measured perpendicularly to the major axis dimension and ranging from 50 percent to 99 percent of the major axis dimension.
