Selecting the right bit depends on the IADC (International Association of Drilling Contractors) code. For soft formations (shale, clay), choose Steel Tooth (Milled Tooth) bits with low IADC codes (111-131). For medium to hard formations (limestone, sandstone), Tungsten Carbide Insert (TCI) bits are essential. Ensure the insert shape (conical, hemispherical, or chisel) matches the rock's compressive strength to prevent premature breakage.
Buyers must prioritize bearing types: sealed journal bearings are preferred for high-speed, long-duration drilling, while open roller bearings are more cost-effective for shallow wells. Additionally, check for gauge protection (hardfacing on the shirtail) to maintain hole diameter and nozzle configuration to ensure efficient cuttings removal and cooling of the cutting structure.
Ensure the manufacturer adheres to API Spec 7-1 (American Petroleum Institute) standards, which govern the threads and rotary drilling equipment. Verification of ISO 9001:2015 for quality management is crucial. For mining or oil & gas applications, request material mill certificates for the steel body and heat treatment records to guarantee structural integrity under high torque.
Focus on Cost Per Foot (CPF) rather than the initial purchase price. A cheaper bit that fails early increases tripping time costs (the time taken to pull the drill string out). Look for suppliers on Made-in-China.com that offer remanufactured or premium used bits if the project budget is tight, but ensure they provide a guarantee on bearing life.
The main risks include logistical damage to threads and customs delays due to improper HS Code classification. Always insist on heavy-duty wooden box packaging with anti-rust oil coating. Use the correct HS Code (typically 8207.19) to avoid fines and ensure the supplier provides a Certificate of Origin to benefit from potential trade agreement duty reductions.
Utilize Secured Payment services provided by platforms like Made-in-China.com to hold funds until the shipping documents are verified. Negotiate a milestone payment structure (e.g., 30% deposit, 70% after third-party inspection but before shipment). Request a video inspection of the specific serial numbers on the bits to ensure they match the technical data sheets.
Due to the high weight-to-volume ratio, Sea Freight (LCL or FCL) is the most economical method. For urgent drilling stoppages, Air Freight is possible but expensive. Ensure the Incoterms are clearly defined; CIF (Cost, Insurance, and Freight) is often easier for new buyers, but FOB (Free On Board) allows for better control over the shipping timeline and local port fees.
