Detailed Description
Product Description of PDC Drag Bits:
PDC non-core bits mainly used for drilling of soft and medium formation, also widely used for geology, coalfield, metallurgy, building, mining, projectsurvey, rail, bridges, housing.
Application of PDC Drag Bits :
These bits are used in penetrate the degassing hole, drain hole,and grouting hole of coal mine. Or used for the purpose of geology, coalfield, metallurgy, building, mining, projectsurvey, rail, bridges, housing.
Introduction of PDC (Polycrystalline Diamond Compact)
PDC is made of diamond micro-powder and hard tungsten carbide under high temperature and high pressure. Therefore, it not only possess high wear resistance like diamond, but also the impact resistance like tungsten carbide,that’s why so many factories made it the best material as a drill bit cutter. After technical innovation, the reinforced one has higher dense diamond powder, claw tungsten carbide substrate to make the two layers solid as whole one. So the reinforced PDC possesses supper wear resistance, longer service life and higher efficiency.
Characteristics of GK PDC:
As our patented products, GK PDC has strong impact resistance and high speed.Compared with others, this one has a higher abradability and wide range of application. We call it "killer of ravelly ground". Applicable rock formation: f≤12.
