从China供应商批发进口81/2inch Tricone Drll Bit — FOB条款

The 8 1/2inch TCI tricone drill bit from Cangzhou JSBIT is engineered for oil drilling, water well development, and coal field exploration in soft-to-hard interbedded formations. It excels in layered geologies such as soft shale, clay, gypsum, limestone, sandstone, conglomerate, and dolomite, delivering consistent penetration rates across variable strata. The bit’s tungsten carbide inserts provide durability in abrasive conditions, while its sealed bearing design reduces maintenance needs in extended drilling campaigns.

This tricone bit features a standard 8 1/2inch diameter, with typical API thread connections (such as 4 1/2inch IF or 6 5/8inch REG) for compatibility with most drilling rigs. The bit body is usually forged from high-grade alloy steel, with a typical weight range of 25-35 kg depending on the specific configuration. TCI bits are standard for their ability to handle high compressive strengths, with typical IADC codes for this size falling between 517 and 537 for soft to medium formations.

Primary buyers include oil and gas contractors, water well drillers, and mineral exploration firms operating in sedimentary basins. The bit is suited for vertical and directional drilling, with typical operating depths up to 3000 meters. Buyers should confirm the exact IADC classification, bearing type (sealed or open), and nozzle configuration to match their formation and rig specifications.
