FEATURES

1. Premium TCI tricone drill bit with high‑strength tungsten carbide inserts. Optimized teeth layout delivers excellent wear‑resistance, extends service life for roller cone bit in abrasive mixed rock formations, reduces frequent bit replacement cost.

2. Sealed reliable bearing & sealing system for stable rotary drilling. Heavy‑duty bearing structure supports high weight‑on‑bit, keeps smooth rotation for tricone bit under heavy‑load conditions, lowers risk of premature bearing failure in water well and mining drilling.

3. Wide formation adaptability for various drilling projects. This tricone drill bit works efficiently in soft, medium and hard strata, suitable for water‑well drilling, mining blast hole, geothermal well and HDD horizontal directional pilot hole drilling.

4. Multiple IADC codes & complete size range available. Customizable tricone roller cone bit covers common diameters, matches most rotary drill rigs, supports OEM service for special drilling site requirements.

5. Optimized hydraulic nozzle design for efficient cuttings removal. Good bottom‑hole cleaning performance improves penetration rate of tricone drill bit, avoids bit balling and enhances overall drilling efficiency for field operation.
