Abstract
A superabrasive element includes at least one superabrasive table including at least one coupling projection having a narrow portion and a wide portion having a greater width than the narrow portion. The superabrasive element includes a substrate defining at least one coupling recess, the at least one coupling recess extending from a narrow portion to a wide portion. At least a portion of the at least one coupling projection is disposed in the coupling recess and the at least one coupling projection and the at least one coupling recess mechanically couple the at least one superabrasive table to the substrate. A drill bit includes a superabrasive element having a superabrasive table.
