The nose has a central core that protrudes outward. A base joins supporting metal of the cone. A free end is opposite the base. Teeth are formed on the cone between the base and the free end, the teeth extending radially outward. A hard facing layer is located on the teeth. Intermediate hardfacings extend outward from the core between each of the teeth. The intermediate hardfacings may be lugs and preferably extend the same distance from the core as the teeth.
