The 14 3/4 Inch 374mm IADC 537 TCI Tricone Drilling Rock Bit from HJ Bit is designed for optimal performance in soft to medium formations. This bit uses tungsten carbide inserts (TCI), featuring a spoon-type insert design that enhances rock-breaking capabilities. The unique design increases the Rate of Penetration (ROP) in harder plastic formations and improves bottom hole coverage. Equipped with elastomer sealed bearings and three jet nozzles, it offers superior durability and performance, making it ideal for oil and gas exploration, water well drilling, and exploration drilling.
The bit's bearings are designed for enhanced self-lubrication, which improves their anti-snapping abilities, while the welding of wear-resistant alloys at the sliding surfaces provides increased bearing capacity. Its O-ring rubber seal offers a robust sealing solution, making it suitable for conventional drill holes. Whether you are working in soft shale, medium soft limestone, or formations with abrasive interbeds, the 14 3/4" IADC 537 TCI Tricone Bit delivers reliable performance under a wide range of conditions.
