ABSTRACT:
The means comprises a sleeve for envelopment of a substantial portion of the drill rod or drive stem of an earth boring machine to provide stabilization of the drill rod during its rotation and earth penetration. Additionally, the sleeve prevents the drill rod from undue abrasion and scoring which normally would occur from direct contact of the rod with the earth. The sleeve is non-rotatable; that is, it is carried on the drill rod by bearings to provide a stable surface within which, and upon which, the drill rod can rotate. As the drill rod moves through the earth the sleeve is carried along therewith.
