• PDC for Geological Drilling
    • The PDC products are super hard compound material, consist of high quality diamond micro powder bonded together by introducing unique cubic press sintering at HTHP. Featured by D-D covalent bond conjunction in diamond particles and the firmly combination in micron powder layer with cemented carbide. Accordingly, there are two main applications, PDC for geological drilling and PDC for oil and gas drilling.
    • PDC products apply to making drill bits like core drill bits, no core drill bits and reaming drill bits in well drilling, oil and gas drilling, hydro geological drilling, engineering geological drilling, etc.
