Tricone drill bits for water wells are crucial tools in the drilling industry, used for water well drilling, geological exploration, and oil drilling. These bits consist of three conical rollers, capable of effectively penetrating various rock layers.
Material: High-quality, heat-treated alloy steel for maximum strength and durability.
Size Range: A complete range of sizes to fit various pin diameters and drilling equipment. From small to large sizes, suitable for different drilling scenarios.
Thread Types: Precision-engineered threads for easy insertion and effective grip.
Standard Compliance: Designed and manufactured according to industry standards, ensuring compatibility with a wide range of drilling equipment.
1. Versatility: Suitable for various strata, from soft rock to hard rock.
2. Durability: Uses grease resistant to temperatures up to 250°C for optimal wear resistance.
3. Efficiency: An optimized flushing system includes three combined nozzles for balanced fluid flow, effective cleaning of the bottom-hole zone, and anti-balling.
