摘要： Methods of manufacturing roller cones for drill bits include providing both integral teeth and non-integral teeth on the roller cones. A layer of hardfacing may be applied to the integral teeth. Non-integral teeth may be formed on a body of a cone, or they may be separately formed from the body and attached thereto. In some embodiments, the non-integral teeth are formed by building-up the non-integral teeth from hardfacing material. Roller cones and earth-boring tools are formed using such methods.
