A cutting element for a drag-type drill bit comprises a cutter body having a generally cylindrical base section adapted for snug-fitting engagement in a socket of a drill bit body. The cutter body is secured to the bit body by brazing or other conventional attachment techniques. The cutter body further has a generally cylindrical cutting section integral with the base section. The cutting section has at least one inclined surface extending from a top surface of the cutting section partially along the length of the generally cylindrical cutting section. The cutter body may comprise a sintered tungsten carbide and the top surface may comprise a layer of super hard material.
