Abstract
Earth-boring drill bits include a bit body, an element having an attachment feature bonded to the bit body, and a shank assembly. Methods for assembling an earth-boring rotary drill bit include bonding a threaded element to the bit body of a drill bit and engaging the shank assembly to the threaded element. A nozzle assembly for an earth-boring rotary drill bit may include a cylindrical sleeve having a threaded surface and a threaded nozzle disposed at least partially in the cylindrical sleeve and engaged therewith. Methods of forming an earth-boring drill bit include providing a nozzle assembly including a tubular sleeve and nozzle at least partially within a nozzle port of a bit body.
