Abstract:
In some embodiments, a cutting element for an earth-boring tool may include a superabrasive table having a recessed surface in a cutting face thereof and a shaped feature in a substrate at the interface between the superabrasive table and the substrate, the shaped feature corresponding to the recessed surface in the cutting face of the superabrasive table. In further embodiments, a cutting element for an earth-boring tool may comprise a superabrasive table positioned on a substrate, and at least one substantially planar recessed surface in a cutting face of the superabrasive table. In yet additional embodiments, a cutting element for an earth-boring tool may comprise a superabrasive table positioned on a substrate, and at least one non-planar recessed surface in a cutting face of the superabrasive table. Such cutting elements may be located on an earth-boring tool. Methods of forming an earth-boring tool include attaching such cutting elements thereto.
