The tricone bit is primarily utilized in drilling, exploration, petroleum, and trenchless operations as a pilot bit.

Based on the type of bearing, the tricone rock bit can be further categorized into metal seal bearing and rubber seal bearing.

When it comes to the cutting material, the tricone bit can be divided into Steel tooth Bit and TCI bit.

To enhance the durability of the Steel tooth bit, a new wear-resistant material is utilized to weld the tooth surface. This ensures a high penetration rate and prolongs the lifespan of the cutting tooth.

The TCI bit utilizes hard alloy teeth with high strength and toughness. The tooth row number, tooth number, tooth exposure height, and unique alloy tooth shape are all optimized, allowing the TCI bit to exhibit exceptional wear resistance and cutting ability.
