The 14 3/4" IADC 437 Tricone Drill Bit by HJ Bit is designed for efficient drilling in very soft formations such as clay, gypsum, salt, and soft limestone. Featuring tungsten carbide inserts (TCI), the bit ensures high drilling efficiency with its conical spherical inserts that break down rocks and create cuttings. The elastomer-sealed bearings ensure smooth operation even at high rotational speeds. It is widely used in water well drilling, oil & gas well drilling, HDD, exploration, and geothermal drilling projects.
Tungsten Carbide Inserts (TCI): Optimized for soft rock formations with high drillability.
Elastomer Sealed Bearing: Provides smooth operation and better durability at high speeds.
Mud Fluid Circulation: Ensures efficient cooling and cleaning during the drilling process.
High Performance: Effective in very soft formations with low compressive strength.
Three Jet Nozzles: For optimal fluid flow and cooling.
