从China供应商批发进口8 1/2 Iadc 537 Roller Cone — FOB条款

This 8 1/2 inch IADC 537 roller cone bit is designed for medium soft formations with low compressive strength and harder abrasive stringers, such as hard shale, hard gypsum, soft limestone, sandstone and dolomite with stringers. The bit features rubber sealed bearings, which provide enhanced durability in abrasive conditions. It is packaged in a wooden case with gauge protection to prevent damage during transit.

The bit uses a proprietary insert arrangement optimised for low torque, a result of the supplier’s research into bottom-hole flow field simulation and profile design. The inserts are manufactured using advanced material techniques to improve wear resistance and service life. Typical for this IADC classification, the bit is suited for applications where balanced drilling efficiency and longevity are required in mixed formations.

This model is primarily used in oil and gas exploration, mining, geothermal drilling and construction projects. Buyers typically confirm the bit’s compatibility with their rig’s rotational speed and weight on bit (WOB) requirements before ordering. The supplier offers wooden case packaging as standard, and buyers should verify the bearing type and sealing specifications match their operational needs.

Hebei Crossing Drill Bit Manufacture Co., Ltd is based in Hejian, Hebei Province, China, with its office and production facilities located on Changqing Road. The company specialises in the design and manufacture of drilling tools, including tricone bits, PDC bits, reamer bits, drag bits, core bits and related accessories. Its product range is industrialised and serialised, covering multiple applications in oil and gas, mining, geothermal and construction sectors.

The supplier has developed proprietary intellectual property through years of research, focusing on bottom-hole flow field simulation, profile optimisation, insert arrangement and low-torque designs. It emphasizes technical collaboration with domestic and international partners and has exported its products to markets such as the United States, Canada, Brazil, Russia and Saudi Arabia. The company’s product portfolio includes both steel-body and matrix-body PDC bits, as well as tricone bits in TCI and milled-tooth (MT) variants.
