Earth-boring tools having threads for affixing a body and shank together and methods of manufacture and use of same
摘要：
Earth-boring tools comprise a shank comprising a distal connector including a set of threads thereon and a bit body comprising a shank connector, also comprising at least one set of threads thereon. The set of threads on the distal connector and the at least one set of threads on the shank connector are at least substantially bound together. Methods of forming such earth-boring tools are also disclosed, as well as methods of securing a bit body of an earth-boring tool to a shank.
