Import Api Steel/Milled Tooth Bit Drill Bits — Buy in Bulk from Supplier in China

API steel milled tooth bit drill bits from Cangzhou Great Drill Bits Co., Ltd. are engineered for soft formation drilling, where low compressive strength materials require efficient cutting action. The bits feature a milled tooth design, which enhances penetration rates and durability in non-abrasive, soft to medium-hard formations such as shale, clay, or soft limestone. Manufactured from high-grade steel, these bits are built to withstand the mechanical stresses of rotary drilling operations.

The milled tooth configuration typically includes tungsten carbide inserts or hardened steel teeth, arranged in a pattern optimised for shearing rather than crushing the formation. Standard bit sizes range from 6 inch to 26 inch, with typical IADC codes falling between 117 and 537 for soft to medium formations. The bits are compatible with standard drilling rigs and can be adapted to various connection types, such as API regular or pin connections.

These drill bits are widely used in oil and gas exploration, water well drilling, and mining operations where precision and reliability are essential. Buyers in these industries often require bits that can maintain performance over extended drilling campaigns. The bits are typically shipped in individual wooden crates or palletised for bulk orders, and buyers should confirm packaging, incoterms, and lead times with the supplier.

Cangzhou Great Drill Bits Co., Ltd. operates from the Industry Zone in Hejian, Hebei Province, China. The company focuses on the design and manufacture of drill bits for the oil and gas, mining, and civil engineering sectors. Its location in Hejian, a region known for its manufacturing base, supports efficient production and distribution within China and for export markets.

The supplier holds a harbor trust tier, though no response rate or average response hours are currently documented. While the source description highlights ISO certifications and compatibility with standard drilling rigs, buyers should independently verify these claims, including the scope and validity of any certifications. The company’s profile does not provide details on production capacity or lead times, which should be confirmed directly with the supplier.
