| 简介 | An earth-boring bit has at least one steel tooth with a scoop-shaped profile. The scoop- shaped profile is formed by milling and hardfacing a tooth to have at least one flank with a concave profile. Additionally, the tooth may contain one flank with a concave profile and another with a convex profile. The centerline axis of the tooth may be moved to alter the angle between the flanks and the centerline to vary the manner in which the tooth engages the formation. | ||
