Tricone bit 11 5/8"GR127

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.

Trimming teeth: Trimming teeth protect the inserts and trim the wall, enhancing the diameter retention of the bit.
