Insightful Tricone Bit Information
The Tricone bit plays a crucial role in sectors such as drilling, exploration, petroleum, and trenchless projects as an initial pilot bit.

Tricone bits can be categorized into TCI bits and Steel Tooth bits based on the cutting materials utilized.

The TCI bit features high-strength, high-toughness alloy teeth, an optimized design considering tooth row and number, tooth exposure height, and a unique alloy tooth shape, maximizing wear resistance and phenomenal cutting efficiency.
With the integration of new wear-resistant materials on the Steel Tooth bit's surface, it maintains its high penetration rate while significantly extending the lifespan of its cutting teeth.
Product Description

TIanrun tricone bit used for geoloical prospecting, development of oil and gas, drilling water wells,blast holes and making holes for
seismic prospecting, construction engineering. now there are eleven common types of tricone rock bits.

Steel teeth series: IADC CODE:116,117,126,127,136,137,216,217,317,337,
TCI series: IADC CODE:417,437,447,517,527,537,547,617,627,637,647,737,837.
