摘要
A drill bit or milling tool includes a bit body on which a plurality of cutting elements are disposed. At least some of the plurality of cutting elements include a diamond table and a superabrasive material non-reactive with iron-based materials disposed over at least a portion of an exterior surface of the diamond table. The diamond table is suitable for drilling through a subterranean formation and the non-reactive superabrasive material is suitable for drilling through a casing or casing-associated component comprising an iron-based material and disposed within the subterranean formation. The diamond table may comprise a PDC and the non-reactive superabrasive material may comprise cubic boron nitride.
