A drilling tool having a body, at least one blade extending from the body, and a first cutting element attached to the at least one blade. The first cutting element includes 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. The elongated protrusion has a geometry including a border extending around a concave surface, a face chamfer formed around the border, and sloped surfaces extending between the border and the edge. An edge chamfer is between the face chamfer and the edge.
