Import 8 1/2"Tci Tricone Bit — Buy in Bulk from Supplier in China

The 8 1/2" TCI tricone bit from Hejian Ruida Petroleum Material Co., Ltd. is a tungsten carbide insert bit designed for rotational drilling in medium to hard formations. It features a sealed bearing design for extended life in abrasive conditions, with a standard IADC code range of 517 to 637 for this diameter. The bit’s three-cone assembly provides balanced cutting action to reduce vibration and improve penetration rates in oil, gas, and mineral exploration applications.

Constructed with high-grade steel bodies and hardfaced tungsten carbide inserts, the bit maintains sharp cutting edges under high-weight-on-bit conditions. Typical industry specifications for this size include a pin connection of 4 1/2" API Reg, a maximum outer diameter of 8.5 inches, and a standard gauge length of 2.5 inches. The inserts are arranged in staggered rows to maximize coverage and prevent tracking, a common requirement for bits targeting formations like limestone, dolomite, and hard shales.

This bit is used by drilling contractors in onshore and shallow offshore projects where cost per foot and durability are critical. Buyers typically confirm the exact IADC classification, bearing type, and nozzle configuration to match their formation and rig setup. The supplier offers standard export packaging with wooden crates and moisture barriers, and buyers should verify compatibility with their drill string and mud motor systems before ordering.
