ABSTRACT:
An improved drill bit seal arrangement, including a seal ring having a boronized outer annular surface which is fabricated separate and apart from the journal bearing structure of the drill bit arm. The seal ring boronized surface is polished to define a smooth non-abrading surface for the elastomeric seal. The seal arrangement enhances the wear resistance of the seal between the drill bit arm and the cutting cone, thereby increasing the life span of the drill bit.
