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.

Scoop teeth: improve the stress condition of teeth, effectively improve the rock breaking efficiency of the roller and increase the strength of teeth, suitable for drilling soft to medium soft formation.

The gauge protection adopts the arrangement of double rows of teeth to enhance the diameter retaining performance and prolong the service time of the bit.

The reinforced alloy tooth arrangement on the palm can effectively protect the shirttail, seal and oil storage hole, effectively improve the stability of the bit, enhance the anti-shrinkage ability and prolong the service time of the bit, especially for directional wells and horizontal wells.
