A cutting element substrate for use with an earth-boring drill bit. The substrate includes a base, or outer shell, with a cavity opening to an end thereof. The base is fabricated from an erosion-resistant and abrasion-resistant material. A core that is configured substantially complementarily to the cavity is disposed within the cavity. The core base is fabricated from a material that is more ductile than the material of the base. The core and base each includes a cutting end to which a superabrasive cutting table, such as a polycrystalline diamond compact, may be secured. The substrate may be secured within a corresponding receptacle of a bit body in order to secure a superabrasive cutting table to the bit body in a desired orientation. The present invention also includes methods of fabricating the cutting element substrate.
