Abstract
An earth-boring tool includes a blade located on a body of the earth-boring tool with a pocket formed in an exposed outer surface of the blade. A formation-engaging structure is affixed within the pocket. The formation-engaging structure includes a distal end, a proximal end and a tapered sidewall therebetween. The distal end of the formation-engaging structure includes a formation-engaging surface. The tapered sidewall engages a tapered inner surface of the pocket. The tapered sidewall of the formation-engaging structure and the tapered inner surface of the pocket are each sized and configured to provide an interference fit between the formation-engaging structure and the pocket of the blade. In additional embodiments, instead of retention by interference fit, the formation-engaging structure is retained to the blade by a threaded fastener threaded within a tapped bore extending through the blade. The threaded fastener is received within a receiving formation of the formation-engaging structure.
