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.
