DXT Tri-Cone Drill Bit – 288mm

The DXT Tri-Cone Drill Bit (288mm), Part Number D28DXT-1771, Batch No. GG2DXT4, is a high-performance roller cone drilling tool engineered for demanding subsurface conditions. Designed with a TCI (Tungsten Carbide Insert) cutting structure, this bit delivers superior durability, enhanced penetration rates, and consistent performance in hard and abrasive rock formations.

Manufactured with precision engineering and classified under IADC 617 (TCI hard rock application), the bit incorporates advanced drilling technology to ensure efficient rotary drilling across oil & gas, geothermal, mining, and water well applications. Its sealed roller bearing system provides improved protection against contamination, significantly extending operational life and reducing downtime in harsh environments.

With a standardized API 8 ½” connection, the DXT Tri-Cone Bit ensures secure compatibility with drilling assemblies, making it suitable for deep-hole and high-load drilling operations. The optimized cone geometry and carbide insert configuration enhance cutting efficiency while maintaining structural integrity under extreme drilling pressures
