Cutting structures for casing component drillout and earth-boring drill bits including same

摘要

A method of forming an earth-boring tool comprises forming a bit body (14). The bit body (14) has a face (26) on which two different types of cutters are disposed, the first type being cutting elements (32) suitable for drilling at least one subterranean formation and the second type being at least one of an abrasive cutting structure (36) and an abrasive cutting element suitable for drilling through a case shoe, reamer shoe, casing bit, casing or liner string and cementing equipment or other components as well as cement.
