Abstract: PDCs, methods of fabricating the PDCs, and methods of using the PDCs are disclosed herein. The PDCs include a PCD table bonded to a substrate. The PCD table includes an upper surface having a plurality of recessed features formed therein. The plurality of recessed features are configured to attract at least some cracks that form in the PCD table. As such, the plurality of recessed features limit or prevent crack propagation into other portions of the PCD table and limit a volume of the PCD table that spalls. Methods of fabricating the PDCs include partially leaching the PCD table and, after leaching the PCD table, forming the plurality of recessed features in the upper surface thereof. Method of using the PDCs include rotating a PDC that has spalled relative to a rotary drill bit such that a portion of the upper surface of the PDC that has not spalled forms a cutting surface thereof.

Abstract: A cutting tool which may be used in machining various material may include a body and one or more cutting elements associated therewith. In one example, the cutting element(s) may comprise a superhard table, such as a polycrystalline diamond table. In some embodiments, the polycrystalline diamond table may have a diamond density of approximately 95 percent volume or greater. In some embodiments, the thickness of the superhard table may be approximately 0.15 inch. In some embodiments, the superhard table may include a chip-breaking feature or structure. Methods of shaping, finishing, or otherwise machining materials are also provided, including the machining of materials comprising titanium.
