从China供应商批发进口12 1/4" Iadc537 Tricone Bit/Rock Roller Bit — FOB条款

This 12 1/4" tricone bit from Hebei Crossing Drill Bit Manufacture is a tungsten carbide insert (TCI) roller bit rated under the IADC 537 classification. The model is specified for a weight on bit (WOB) range of 0.35 to 1.05 kN/mm and a rotary speed (RPM) range of 110 to 40. The bit is designed for drilling in medium-soft formations with low compressive strength that contain harder abrasive stringers, such as hard shale, gypsolyte, soft limestone, sandstone, and dolomite.

The IADC 537 code indicates a steel tooth bit for soft to medium formations, though this model features TCI inserts for enhanced wear resistance. Typical industry specifications for a 12 1/4" (311.15 mm) tricone bit include a standard API connection, often 6 5/8" REG or 7 5/8" REG. The manufacturer states their products benefit from proprietary research in analogue simulation of bottom-hole flow fields, profile optimization, and low-torque design, which are common focus areas for improving drilling efficiency and bit life.

These tricone bits are sourced for water well drilling, oil and gas exploration, mining, geothermal, and construction applications. Buyers include drilling contractors and service companies operating in regions with mixed lithology. The supplier's products are exported to markets including the United States, Canada, Brazil, and Russia. Specific trade terms such as minimum order quantity, pricing, and lead time should be confirmed directly with Hebei Crossing Drill Bit Manufacture.
