About Cangzhou Great Drill Bits Co., Ltd. - Drilling Tools Supplier in China

Cangzhou Great Drill Bits Co., Ltd. is based in Cangzhou, China and lists 17 active products across drilling machines, tools, excavator spare parts and packaging drums. The catalogue contains a mixture of PDC bits, tricone bits, steel‑body bits, hole openers, sand dredging buckets and core barrels, each identified by product name but without specific HS codes in the source data. These items are typically classified under HS Chapter 84 for drilling machinery and HS Chapter 73 for steel tools and barrels, reflecting the material composition and intended use. The supplier is marked as an imported tier with a harbor trust rating, indicating that it primarily serves overseas buyers rather than domestic retail markets.

The product set includes items such as Matrix Body and Steel Body PDC Bit, API‑qualified TCI Tricone Bits for water‑well and oil‑and‑gas drilling, API Great PDC Drill Bit, and a range of steel‑milled tooth bits. Additional listings cover a Hole Opener, Flat Tooth Sand Dredging Bucket, Water Well Drill Bits, Latent Reaming Drill Bit and a Core Barrel, representing both down‑hole cutting tools and auxiliary drilling equipment. While the source facts do not provide HS codes for individual items, similar products normally carry HS codes 8465 (drilling or well‑bore tools) or 8205 (hand tools and parts) and steel barrels fall under HS 7315.

Product Range and Specialties of Cangzhou Great Drill Bits Co., Ltd.

The catalogue focuses on down‑hole cutting tools: PDC (polycrystalline diamond compact) bits, tricone bits, steel‑body and steel‑milled‑tooth bits, plus ancillary equipment such as hole openers and core barrels. In the drilling industry PDC bits are commonly graded to API 7‑1 or 7‑2 specifications, with cutter diameters ranging from 76 mm to 305 mm and cutter concentrations expressed in cutters per square inch. Tricone bits are usually classified by API 7‑1, API 7‑2 or API 7‑3 grades, featuring tungsten‑carbide inserts and cone spacing that matches formation hardness. Steel‑body bits and milled‑tooth bits are often produced from high‑strength alloy steel (e.g., AISI 4340) with heat‑treated teeth for water‑well applications.

Packaging drums and barrels listed under the “Packaging Drums & Barrels” category are typically fabricated from carbon steel, conforming to HS 7315 specifications. Standard dimensions for export drums include 200 L capacity, 0.9 mm wall thickness and a 1,200 mm height, with steel drums often coated for corrosion resistance. Buyers generally look for ISO 9001‑certified manufacturing processes and may request material test reports confirming tensile strength and impact resistance of the steel used.

Trade and Export Information - Cangzhou Great Drill Bits Co., Ltd.

China is a major exporter of drilling equipment, supplying oil‑field services and water‑well contractors in the Middle East, North Africa, South America and Southeast Asia. Export shipments of PDC and tricone bits usually fall under HS 8465, while steel tools and barrels are classified under HS 8205 and 7315 respectively; customs authorities often require a commercial invoice, packing list and, for API‑specified bits, a declaration of conformity to API standards. Common buyer‑required certifications include API product specifications (e.g., API 7‑1), ISO 9001 quality management, and where applicable ISO 14001 environmental management. Logistics for these items typically involve 20‑ft or 40‑ft containers packed on wooden pallets, with Incoterms such as FOB Cangzhou or CIF Shanghai depending on buyer preference.

The supplier’s target markets are not listed in the source facts, so buyers should anticipate that Chinese drill‑bit exporters normally serve oil‑field operators in the Gulf Cooperation Council, mining firms in Sub‑Saharan Africa, and water‑well developers in South Asia. Importers often arrange pre‑shipment inspections (PSI) through third‑party agencies to verify API compliance and dimensional tolerances before the cargo is loaded onto the vessel.

Sourcing from Cangzhou Great Drill Bits Co., Ltd. - Buyer Guidance

When sourcing PDC or tricone bits from this supplier, request the specific API grade sheet (e.g., API 7‑1 or API 7‑2) and a recent material test report showing hardness, compressive strength and cutter wear rating. Verify that the manufacturer can provide ISO 9001 certification or an equivalent quality‑management audit report, as these are standard requirements for oil‑field tooling imports.

For ancillary items such as hole openers, sand dredging buckets and core barrels, ask for engineering drawings that detail dimensions, wall thickness, and load‑bearing capacity. Request a sample or a third‑party inspection report confirming that the steel conforms to ASTM A572 or equivalent specifications before placing a full order.

What types of drill bits are listed in the catalogue?

The catalogue includes Matrix Body and Steel Body PDC bits, API‑qualified TCI tricone bits for water‑well and oil‑and‑gas drilling, steel‑milled‑tooth bits, and a generic PDC bit entry.

Which industry standards are typically applied to the bits offered?

Bits for oil‑field use are usually produced to API specifications such as API 7‑1, 7‑2 or 7‑3, and many manufacturers also follow ISO 9001 quality‑management standards.

What HS code families do these products belong to?

Down‑hole cutting tools like PDC and tricone bits are generally classified under HS 8465, while steel tools and barrels fall under HS 8205 or 7315 depending on the exact item.

What certifications should a buyer request from the supplier?

Buyers should request API product specification sheets, ISO 9001 (or ISO 14001 if environmental compliance is needed) and material test reports confirming steel grade and hardness.

How are the drill bits typically packaged for export?

Export shipments are usually packed in wooden crates or on pallets inside 20‑ft or 40‑ft containers, with each bit protected by foam or cardboard inserts to prevent impact damage.

What is the usual lead time for orders of PDC bits?

Lead times for PDC bits from Chinese manufacturers range from 30 to 45 days after receipt of a confirmed purchase order and required certification documents.

Are samples available before a full order?

Suppliers often provide a single sample or a small batch for testing, provided the buyer covers sample shipping costs and signs a non‑disclosure agreement if required.

What documentation is needed for customs clearance?

Customs typically requires a commercial invoice, packing list, certificate of origin, and, for API‑specified bits, a declaration of conformity to the relevant API standard.
