    What is the cutter structure of single roller cone drill bit?

    In roller tooth surface, according to the single cone bit cone on tooth movement cutting way different

    characteristics, different regions of permanent decorate cone ball tooth contact area, alternate contact region decorate a cog to improve the efficiency of the teeth and broken rock, the most serious permanent tooth wear on the roller contact region, diamond composite tooth arrangment strengthen tooth wear resistance. Cone roof with conservation of rock matrix in the plane of the tungsten carbide prevent rock basic wear and tear.

    What is the guage structure of single roller cone drill bit?

    Tooth claw part guage set active active guage cone ball or wedge tooth, cutting bit has a good conservation gauge function and redressing function.

    What is the bearing structure of single roller cone drill bit?

    Using radial sliding bearing, the adaptation of the tooth claw journal welding with wear-resisting gold, inner hole welding special alloys, enhance bearing abrasion resistance and resistance to bite and ability.

    What is the hydraulic design of single roller cone drill bit?

    Using small Angle nozzle flow design, enhance the claw back thickness, can effextively prevent the flow channel erosion. Optimization design of hydraulic structure can enhance the cleaning ability of the hydraulic system. Improve the rate of penetration.

    What is the application of single roller cone drill bit?

    Single roller bit is suitable for old and old-well window sidetrack drilling and deepen the well of slim hole drilling operations.

    What is the specification of single roller cone drill bit?
