Highlights

* Maximum ROP

* Running durable

* safety and reliability

*extended bearing life

Improved structure of teeth and rubber seals

Further increase rate of penetration, footage and the life of tricon bits.

 

 Tricon bits with ancillary teeth sprue

the strengthened ancillary teeth play the role of crashing for the second time, they assist the main teeth to smash large rock timely, and crash protuberance of rocks. They protect the basal body of tricone bits as well as accelerate the smooth clear-up of crashed rocks.

 

Carbonization intensified

Effectively improve anti-reosion ability of sprue surface of toth palms, and increase the adaptability of tricone bit to all kinds of conditions of drill holes, such as high pump pressure, large output volume and combined spray nozzles, etc.
