PDC Special Superhard Materials Drill Bit

1.We bought our own land and built our own factory. 2.Advanced geometric design for faster penetration. 3.PDC is made of diamond micro-powder and hard alloy substrate under high temperature and high pressure. It possess of high wear resistance like diamond, at the same time the impact resistance like hard alloy and that’s made it the best material as a drill bit cutter. Reinforced PDC has higher dense diamond powder, claw hard alloy substrate made the two layers solid as whole one. So, the reinforced PDC of supper wear resistance, longer service life and high efficiency. 4.Recommended parameters: Φ28 Φ30 Φ32 Φ48 Φ56 Φ75 Φ94 Φ110 Φ152 Φ190 Φ230 Φ270 WOB(Kg)300-700 300-700 300-700 300-700 320-800 48-1200 640-1600 880-2200 1500-3000 1800-4000 2200-4500 2400-5000 Speed(rpm) 300-350 300-350 300-350 300-350 250-350 200-300 150-250 120-200 100-200 100-200 100-200 100-200 WOB(1/min) 150-200 150-200 150-200 120-160 130-180 150-200 200-250 200-300 500-850 600-1200 750-1400 1000-1500 Best fit rock Type Fit rock General PDC drill bitsF‹10Soft or middle hard rock Strengthen the PDC bitF=10-12 middle hard rock PDC bit Big strengthF‹18 hard rock
