ABSTRACT:
A rotary cone rock bit featuring a reproducible geometry and a one piece body is disclosed. Individual journal members, supporting rotary cutting cones, have upwardly extending structural shanks which are radially oriented and installed into downwardly directed individual hubs formed by the structural body of the rock bit. The shanks are subsequently secured as installed within the hubs. The primary controls over bit geometry comprise the radial orientation of the individual journal member, and the radial location of the individual hubs relative to the vertical bit body centerline.
