The 15 1/2" IADC CODE 127 Steel Tooth Tricone Rock Bit from HJ Bit is engineered for high-efficiency drilling in soft rock formations. Specifically designed for use in mudstone, gypsum, salt, and soft limestone, this bit excels in challenging environments with low compressive strength. Featuring a robust steel tooth design, this drill bit ensures fast penetration and long-lasting performance. The precision-engineered bearing structure and nozzle system improve overall functionality, delivering effective fluid flow and maximizing drilling efficiency in water well, oil, and geothermal projects.
Steel Tooth Design: Optimized for efficient cutting in soft formations, ensuring fast penetration and reduced wear.
High-Flow Nozzles: Sturdy nozzles enhance fluid flow, optimizing fluid distribution to the cones for improved drilling.
G-Gauge Protection: Tungsten carbide inserts at the gauge minimize wear and enhance bit stability.
Durable Bearings: High precision journal bearings with thrust faces and silver-plated coatings ensure abrasion resistance and long lifespan.
Efficient Circulation: Elastomer sealed bearing provides improved sealing and less friction, allowing for high-speed rotation.
Fast Drilling: Steel tooth design provides high rate of penetration (ROP), reducing overall drilling time.
Extended Durability: Tungsten carbide protection and optimized bearing structure enhance the bit’s lifespan, minimizing downtime.
High Efficiency: Better fluid circulation and nozzle performance improve overall drilling speed and efficiency.
Low Maintenance: The robust construction reduces wear and the need for frequent maintenance, saving costs.
Versatile Use: Ideal for soft formations like mudstone, gypsum, and soft limestone, making it versatile across various applications.
Water Well Drilling: Efficient in soft formations like mudstone and gypsum, commonly used in water well projects.
Oil & Gas Drilling: Suitable for drilling soft to medium formations in oil exploration.
Geothermal Drilling: Well-suited for geothermal well drilling in soft rock environments.
Mining and Construction Projects: Effectively used for mining and other construction drilling projects where soft formations are encountered.
