PDC Bits

Full Size 4-Wing Concave PDC Water Well Bit

Full-Size 4-Wing Concave PDC Bit | Water Well & Mining Drilling

As a professional OEM/ODM PDC drill bit manufacturer in China, we supply full-size 4-wing concave PDC bits specially optimized for water well drilling, rural well construction, mining exploration, and geological drilling projects. Covering complete inch specifications from 3 inch to 12 inch, our concave PDC drill bits perfectly match different drilling depths, rig models, and soft-medium hard formation working conditions, serving global clients in Africa, Russia, Southeast Asia and other mainstream drilling markets.
Different from conventional flat PDC bits , our 4-wing concave design features a sunken central structure and reinforced integral blade body. This innovative structure greatly improves hole centering performance , effectively solves hole deviation, bit wandering and hole collapse problems in loose soil, sand layer, weathered rock and broken mixed strata. Meanwhile, the multi-group optimized water flushing channels realize fast cuttings discharge, avoid bit balling and mud sticking, and greatly improve drilling efficiency and bit service life.
We support complete customizable inch sizes to meet all conventional drilling engineering needs. Our standard available sizes cover: 3", 3 1/2", 4", 4 1/2", 4 7/8", 5", 5 3/4", 6", 6 3/4", 7", 8", 9", 10", 12 inch . All bits adopt high-grade diamond composite cutters, with high wear resistance, high impact resistance and stable drilling performance, suitable for long-term high-intensity drilling operations.
All our 4-wing concave PDC water well bits are factory direct sales, with strict quality inspection, stable delivery cycle and flexible customization services (thread type, cutter grade, blade hardness). Widely applied in civil water wells, agricultural irrigation wells, mine blast holes, geological exploration holes and foundation drilling, our products have won high recognition from drilling contractors, engineering companies and tool wholesalers worldwide.
