The API TCI tricone bit is a tungsten carbide insert (TCI) drill bit designed for oil and gas well drilling in medium to hard rock formations. It features three rotating cones with hardened steel teeth and tungsten carbide inserts to enhance durability and penetration rates. The bit’s design allows for efficient crushing and shearing of rock, making it suitable for deep and deviated wells.
Constructed from high-grade steel, the bit body undergoes heat treatment to resist abrasion and impact damage. The cones are mounted on sealed roller bearings, lubricated with grease to extend service life in high-temperature, high-pressure environments. Standard API TCI bits for oil and gas applications typically include jet nozzles for drilling fluid circulation, with nozzle sizes selected based on formation type and flow rate requirements.
Cangzhou Great Drill Bits Co., Ltd., based in Hejian, Hebei, supplies these bits for contractors targeting formations such as limestone, dolomite, and sandstone. The bits are used in both onshore and offshore drilling projects where consistent performance and longevity are required. Buyers should confirm the bit’s IADC code, cone geometry, and compatibility with their rig’s rotary table and drill collar specifications.
| API Classification | TCI (Tungsten Carbide Insert) |
| IADC Code | Typical 517, 537, or 617 for medium to hard formations |
| Bit Diameter | Standard 6 to 26 inches (common sizes: 8.5", 9.5", 12.25") |
| Cone Material | High-strength steel with tungsten carbide inserts |
| Bearing Type | Sealed roller bearings |
| Lubrication | Grease-packed with pressure compensation |
| Nozzle Configuration | Standard 3-jet or 4-jet (adjustable or fixed) |
| Nozzle Size | Typical 8 to 16/32 inches (API standard) |
| Operating Temperature | Standard up to 150°C (302°F) |
| Connection Type | API Regular Pin (1-1/2" to 6-5/8") |
Cangzhou Great Drill Bits Co., Ltd. is located in the Industry Zone of Hejian, Hebei Province, China. The company specialises in manufacturing and supplying drill bits for the oil and gas sector, with a focus on API-compliant TCI tricone bits. Its profile indicates an importer-tier classification, though no active response rate or verification signals are currently available.
The supplier does not disclose production capacity, certifications beyond API compliance, or export markets in its listing. Buyers should request detailed documentation, including API monogram certificates, material compositions for the bit body and inserts, and performance records in similar formations. As an importer-tier supplier, it may source components or finished bits from multiple manufacturers, so traceability and quality control processes should be confirmed directly.

Prior to ordering, confirm the bit’s IADC code and diameter match your wellbore requirements and formation type. Verify the cone material and tungsten carbide grade to ensure they are suited to your target hardness. Request the supplier’s application guidelines for Weight on Bit (WOB) and rotary speed to optimise performance and avoid premature wear.
Logistics arrangements should account for the bit’s size and weight, as larger diameters (e.g., 12.25") may require special handling. Agree on Incoterms such as FOB Tianjin or CIF, and clarify whether the supplier can provide wooden crates or palletised shipping to prevent damage. Lead times for custom IADC codes or nozzle configurations can extend to 6-8 weeks.
Quality checks should include visual inspection of the tungsten carbide inserts for cracks or improper welding, as well as dimensional verification of the bit diameter and connection threads. Test the bearing seals by submerging the bit in water to check for leaks. Ensure all documentation, including API monogram certificates and packing lists, is complete to facilitate customs clearance and on-site verification.
