Product Description

It is suitable for sidetracking, deep well drilling and old well repairing.

1 Two watercourse can improve washing endurance and prevent mud.
2 Silver-plated at sliding surfaces of cone bearing to strength self-lubricating effect, and improve the bearing of wear-resisting life.
3 The bit inlaid with diamond compact teeth can be more effectively improve working life.
4 Two advanced high-saturated buna-N rubber seal rings are used for journal and bearing pin sealing, which ensured the high reliability of the bearing seal structure.
5 The bearing is improved by applying hard facing layer on head bearing surface, extended working life.
