ABSTRACT:
A stabilized drill string component includes an elongated tubular body. This body comprises a tubular stabilization section and at least one further tubular section. These tubular sections are integrally joined together in axially aligned relation. The stabilization section is much shorter than the further tubular section or sections but has a somewhat greater diameter than the latter such that the stabilization section can assist in stabilizing the drill string component during drilling by way of contact with the wall of the well bore. The wearing surfaces of the stabilization section are of substantially harder material than that of the further tubular section or sections thereby to provide substantial resistance to wear.
