DRILL BITS HAVING TAILORED DEPTH OF CUT CONTROL FEATURES AND RELATED METHODS
Abstract:
An earth-boring tool comprises a bit body and first and second depth of cut control (“DOCC”) features mounted thereon. The first and second DOCC features comprise a first rubbing surface having a first surface area and a second rubbing surface having a second surface area, respectively, for contacting a subterranean formation. The second surface area is different from the first surface area such that the first and second DOCC features distribute a load attributable to applied weight on bit over the first and second rubbing surfaces at different rates. Methods of forming an earth-boring tool include selecting first and second DOCC features having different rates of engagement with the subterranean formation and mounting the first and second DOCC features on a bit body.
