摘要：
Earth-boring rotary drill bits may include a bit body attached to a shank assembly at a joint. The joint may be configured to carry at least a portion of any tensile longitudinal and rotational load applied to the drill bit by mechanical interference at the joint. The joint may be configured to carry a selected portion of any tensile longitudinal load applied to the drill bit. Methods for attaching a shank assembly to a bit body of an earth-boring rotary drill bit include configuring a joint to carry at least a portion of any tensile longitudinal and rotational load applied to the drill bit by mechanical interference. The joint may be configured to carry a selected portion of any tensile longitudinal load applied to the drill bit by mechanical interference.
