O ring rubber seal: Made of highly saturated nitrile rubber with high temperature resistance and high wear resistance. Rubber sealed bits have good stability and wide applicability in conventional drilling.

Sliding bearings: This series adopts sliding bearings. The technology of surfacing wear-resistant alloy on the surface of the tooth palm and silver plating on the inner hole of the cone can effectively improve the bearing capacity and anti-seizure ability of the bearing, and can drill stably in high pressure and medium to high speed.

Chisel tooth: The main teeth are chisel teeth, they have high cutting efficiency and strong crushing resistance, and can effectively improve the ROP of the bit. Suitable for medium soft to medium hard formation.
