Advantages of PDC cutters:
1. high hardness, abrasion resistance and impact resistance
2. high speed
3. Cutter layout is force balanced to drill a precise round hole and reduce bit whirl
4. Gauge pads have tungsten carbide inserts for maximum wear resistance
5. The diamond layer with thickness over 1 mm increases abrsion resistence of PDC cutter.
Applications of PDC cutters:
Mainly for coal mine drilling and oil&gas drill bits. This kind of PDC is sintered by high pressure and temperature which is composed of diamond and tungsten carbide. It can be embedded into mine drill to use in shallow stratum drilling for it is economical and durable.
Introduction of PDC:
PDC is made of diamond micro-powder and hard tungsten carbide under high temperature and high pressure. It possess of high wear resistance like diamond, at the same time the impact resistance like tungsten carbide and that's made it the best material as a drill bit cutter. Reinforced PDC has higher dense diamond powder, claw tungsten carbide substrate made the two layers solid as whole one.
Our PDC cutters have different quality levels:
1)That cheap PDC cutters have high cost performance, they can be as gage protection cutters, gage trimmer, core cutters, backup cutters and back-ream or up-drill.
2)That high quality PDC cutters have improved the wear resistance several times, they can be main cutters on bits.
Guilin Star Diamond Superhard Material Co.,Led.was founded in 2007, located in Gilin,China.Our comany has been identified as the Nationl High -Tech Enterprise that specializes inthe research,decelopment and production of polycrystalline diamond compact(PDC) and PDC bits,and produce 1,000,000 pieces of cutters and 500,000pieces of bts each year. These products are widely used in coal mines, mental mining, water and geothermal well drilling, geology exploration,mechanical industry and oil&gas field drilling.
