Abstract
A cutting element, cutting edge and method of making cutting edges is disclosed. A compound material, preferably containing 30-70 vol % of carbides, nitrides and/or carbonitfides, is co-extruded with a steel cover. The co-extended product is cut into tip blanks whose outer surface corresponds to surfaces of a cutting element body. The steel cover is brazed to corresponding contact surfaces on bodies of a cutting element, e.g., a saw blade, and the cutting edges are ground by removing portions of the steel cover and the compound material.
