5) Hejian Ruida petroleum materials Co., Ltd specializes in drill bits, tricone bits, PDC bits bit size range from 3 7/8"to 26", cover most of IADC codes. Specifications Bit Size: 4 1/2"-- 171/2"(114mm--444.5mm) Blades: 3--9 Blades Nozzles: according to your requirement PDC Cutter: 1913,1613,1313 Rotary speed:60-300 rpm Delivery terms:within 3 days after the payment Package: Iron Boxes. as customers requirements Introduction of PDC (Polycrystalline Diamond Compact): 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 solidas whole one. So, the reinforced PDC of supper wear resistance, longer service life and high efficiency.
