Import Cone Cutter — Buy in wholesale FOB from Supplier in China

The cone cutter is a critical component of tricone drill bits, designed with rotating conical bodies fitted with tungsten carbide or hard alloy teeth to crush and grind medium to hard rock formations during drilling operations. This unit is engineered for direct integration into tricone bits used in oil, gas, mining, and geothermal boreholes, where impact resistance and wear durability are non-negotiable. The cutter's geometry ensures optimal load distribution across the teeth, reducing premature failure under high axial and rotational forces.

The teeth are typically made from tungsten carbide grades such as YG6, YG8, or YG11, with hardness values ranging from 88 to 92 HRA, and are brazed onto steel bodies using high-temperature alloy solders. The base material of the cutter body is usually alloy steel 42CrMo4 or 40Cr, heat-treated to achieve a Rockwell C hardness of 28 to 34, balancing toughness and wear resistance. These material choices are standard in the industry for downhole tools exposed to abrasive formations like sandstone, limestone, and basalt.

Cone cutters are sold as replaceable components for tricone bit assemblies, often supplied in sets of three per bit. Buyers commonly order in quantities of 50 to 500 units, depending on drilling rig deployment schedules. The supplier offers direct factory pricing with standard export packaging in wooden crates, protected with rust-inhibiting oil. Lead times are typically 15 to 30 days after order confirmation, and payment terms are commonly 30% advance with balance against copy of bill of lading. Incoterms are usually FOB Cangzhou Port.

Hejian Sanlong Petroleum Machinery Co. Ltd. operates from Shijing Village in Hejian City, Hebei Province, China, specializing in the manufacturing of downhole drilling components including cone cutters, tricone bits, and PDC inserts. The company is registered as a manufacturer with no public disclosure of export volume, certifications, or client list. Its trust tier is classified as harbor, indicating basic supplier verification through shipping documentation. Response rate and average response time are not tracked by the platform, suggesting limited engagement with international buyers.

The supplier does not claim ISO certification, laboratory testing capabilities, or in-house R&D. Production appears to be based on standard industry patterns for Chinese-made drilling tools, with no evidence of proprietary designs or custom engineering services. The company's listing does not reference export history, past projects, or quality control protocols beyond general claims of durability. Buyers should treat this as a factory-level producer without third-party quality assurances unless verified directly.
