PDC Bits

4-Wing PDC Drill Bit

Four-Wing Concave PDC Drill Bit with 1308 Reinforced Composite Cutter is a heavy-duty drilling tool specially engineered for tough mine exploration and water well drilling conditions. Unlike standard PDC bits with ordinary cutters, this four-wing concave drill bit is equipped with upgraded 1308 reinforced PDC composite cutters that feature higher hardness, thicker substrate, superior impact resistance, and extreme compression and wear resistance.
The enhanced cutter structure effectively prevents tooth chipping, cutter shedding, and rapid abrasion when drilling in complex, uneven, and hard interbedded strata, ensuring stable penetration and continuous working performance during high-intensity, long-cycle mining and water well construction.
Designed with an optimized four-wing concave streamline structure, the bit delivers low drilling resistance, fast rock breaking speed, and excellent chip removal capacity, greatly improving overall drilling efficiency and effectively avoiding common problems such as bit sticking and hole deviation in complex formations. We provide full-size customizable services , supporting both standard and non-standard diameter customization to match different borehole requirements and construction scenarios.
This drill bit comes with a complete range of thread options, including Z-42, Z-50, Z-76, Z-88, 2 3/8REG, 2 7/8REG, 3 1/2REG, and 4 1/2REG, ensuring perfect compatibility with most domestic and international drilling rigs. As a professional factory specializing in mine and water well PDC drill bits , we supply high-strength, long-lasting, cost-effective custom drilling bits and one-stop drilling solutions for global engineering contractors.
