Tricone Bit Information
The Tricone bit is an indispensable tool in the realms of drilling, exploration, petroleum, and trenchless operations, serving with distinction as a pilot bit.

Categorized by cutting material, the Tricone bit is available in two main types: TCI Bit and Steel Tooth Bit.

The TCI Bit is engineered with high-strength, high-toughness hard alloy teeth. Its optimized tooth row and number design, coupled with ideal tooth exposure height and unique alloy tooth shape, ensure exceptional wear resistance and cutting ability.
A new wear-resistant material applied to the Steel Tooth Bit's surface welding preserves its impressive penetration rate while significantly enhancing the longevity of the cutting tooth.
