CUTTING ELEMENTS FOR EARTH-BORING TOOLS, EARTH-BORING TOOLS INCLUDING SUCH CUTTING ELEMENTS AND RELATED METHODS

摘要

Cutting elements, earth-boring drill bits having such cutting elements and related methods are described herein. 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.
