从China供应商批发进口8 1/2 Iadc 547 Tricone Drill Bit — FOB条款

The 8 1/2 inch IADC 547 tricone drill bit is engineered for medium soft formations with low compressive strength and harder abrasive stringers, including hard shale, hard gypsum, soft limestone, sandstone and dolomite with stringers. It operates within a WOB range of 0.35 - 1.05 and an RPM range of 110 - 40, making it suitable for rigs with variable speed requirements. The bit features rubber sealed bearings for enhanced durability in abrasive conditions.

This model incorporates the supplier’s advances in bottom-hole flow field simulation, profile optimisation and insert arrangement design to reduce torque and improve stability. The tricone configuration ensures balanced drilling, while the sealed bearings extend the bit’s lifespan in challenging formations. Typical for IADC 547 bits, the design prioritises penetration rates in softer formations with intermittent harder layers.

Applications for this bit span oil and gas exploration, mining, geothermal drilling and construction. Buyers should match the bit’s IADC classification to their formation’s hardness and abrasiveness, as the 547 code indicates a focus on medium soft conditions with some abrasive content. The supplier’s wooden case packaging with gauge protection ensures safe transit, but buyers should confirm handling procedures to avoid damage.

Hebei Crossing Drill Bit Manufacture Co., Ltd operates from Hejian, Hebei Province, China, with its production and administrative offices located on Changqing Road. The company specialises in a wide array of drilling tools, including tricone bits (TCI and milled-tooth), PDC bits (steel and matrix body), reamer bits, drag bits, core bits and accessories such as nozzles and bit breakers. Its products are industrialised and serialised, catering to diverse sectors like oil and gas, mining and geothermal drilling.

Through years of research and development, the supplier has achieved breakthroughs in bottom-hole flow field simulation, profile optimisation and insert arrangement design, resulting in bits with lower torque and improved service life. The company collaborates with domestic and international partners to refine its manufacturing techniques and has exported its products to global markets, including the United States, Canada, Brazil, Russia and Saudi Arabia.
