Claim:
A drill bit for drilling a subterranean formation subsequent to drilling through at least one component at a distal end of a casing or liner string, the drill bit comprising: a bit body having a face at a leading end thereof; a first plurality of cutting elements of at least one type disposed over the bit body, cutting elements of the at least one type each exhibiting an exposure; and a second plurality of cutting elements of at least another, different type disposed over the bit body, each cutting element of the at least another, different type exhibiting an exposure relatively greater than an exposure of a proximate cutting element of the at least one type; wherein at least one cutting element of at least one type and at least one cutting element of the at least another, different type are arranged together in a single structure and disposed in a single pocket on the bit body, the at least one cutting element of the one type having a first at least substantially planar, exposed cutting face extending to a first cutting edge exposed prior to drilling a subterranean formation with the drill bit, the at least one cutting element of the at least another, different type having a second at least substantially planar, exposed cutting face extending to a second cutting edge prior to drilling a subterranean formation with the drill bit, the second cutting edge having an exposure greater than an exposure of the first cutting edge.
