Roller cone bits include a steel bit body having a leg extending
therefrom. A steel cone is disposed on the leg and includes steel cutting
elements projecting outwardly therefrom. One of the cutting elements
comprises a steel base integral with the cone and that projects
therefrom. A cutting element end is attached to the base portion and
extends to form a cutting element tip. The base and end portions are
attached when the cone base are in a preexisting rigid state. The end
portion comprises a wear resistant material having a material
microstructure comprising a first phase of grains selected from the group
of carbides, borides, nitrides, and carbonitrides of W, Ti, Mo, Nb, V,
Hf, Ta, and Cr refractory metals; and a second phase of a binder material
selected from the group consisting of Co, Ni, Fe, and alloys thereof.
