The Hengji 11 5/8'' 295mm IADC CODE 537 Tricone Roller Bit is designed for efficient drilling. It uses a Tungsten Carbide Insert (TCI) tooth type for cutting. The elastomer-sealed bearing ensures stable operation. Mud fluid is used for circulation during drilling. The thread connection is a 6 5/8 API REG PIN, allowing standard compatibility. Three jet nozzles provide effective fluid flow. Gauge and shirttail protection increase its durability. It performs at speeds of 50–120 RPM and supports 0.45–1.0 KN WOB.
