摘要:
A roller cone drill bit for drilling earth formation includes rows arranged on each of the cones such that, when viewed in routed profile, cutting element profiles partially overlap other cutting element profiles. The roller cone drill bit having at least a first three interior rows adjacent a gage row, each have a cutting element count selected from the group of 16, 18, 21 and 26 cutting elements.
