Import Drill Bits — Buy in Bulk from Supplier in China

These drill bits are designed for rotary drilling in medium-hard formations, featuring a fixed cutter configuration with five blades and three distinct cutter sizes: 19mm, 16mm, and 13mm. The bit has a 4-1/2" API regular connection, a gauge length of 100mm, and a net weight of 57kg with a gross weight of 72kg. Six nozzles are installed, sized at 14/32 inch and 15/32 inch, ensuring efficient cuttings removal during operation.

The cutters are arranged with 20 cutters of 19mm diameter, 14 of 16mm, and 28 of 13mm, following standard IADC code S323 for roller cone bit design. This configuration is typical for PDC-style fixed cutter bits used in oilfield and geotechnical drilling applications. The bit body is manufactured from high-strength alloy steel with wear-resistant hardfacing on the gauge and blade surfaces, a standard practice in the industry to extend service life under abrasive conditions.

These bits are primarily purchased by drilling contractors operating in onshore oil, gas, and water well projects across Asia and the Middle East. Buyers typically require consistent cutter alignment and balanced hydraulics for stable penetration rates.
