EARTH-BORING TOOLS INCLUDING FORMATION-ENGAGING STRUCTURES HAVING RETENTION FEATURES AND RELATED METHODS

An earth-boring tool includes a formation-engaging structure with a formation-engaging surface at a distal end and a side surface between a proximal end and the distal end along a central axis of the formation-engaging structure. A generally linear recess may be formed in the side surface along an a...

Zusammenfassung:An earth-boring tool includes a formation-engaging structure with a formation-engaging surface at a distal end and a side surface between a proximal end and the distal end along a central axis of the formation-engaging structure. A generally linear recess may be formed in the side surface along an axis oriented at a non-parallel angle relative to the central axis of the formation-engaging structure. A generally helical recess may be formed in the side surface, and the generally helical recess may intersect the generally linear recess. Earth-boring tools may include such formation-engaging structures. Methods may be used to form such formation-engaging structures.
