Our factory uses two kinds of diamond composite sheets, which are flat sheets and spherical sheets. The flat sheet has fast footage and a complete stratum.

The spherical sheet has strong impact resistance, is not easy to break, and is suitable for crushing and complex stratum.

PDC diamond drill bits have matrix and steel body two types. The specification from 75mm – 660mm. It suits the soft to mid-hard formation. The series of drill bit has advantages of high efficiency, long life, low-cost drilling, and repairability.

PDC hole opener is the guide reamer that uses polycrystalline diamond composite pieces as cutting tools, it is mainly used in mine ventilation holes, geological prospecting and exploration holes, trenchless and deep scientific drilling, or other reaming constructions. The ream blade wing and drill steel body connect with a set of two connecting pins fixed, structural connect reliably without no moving parts, it was also easy to replace worn blade wing, by replacing different specifications blade wing adjustable the reamer diameter. We use good wear resistance, strong erosion, and thermal stability high efficient composite pieces they make the high drilling efficiency and long life advantages. The blade head and gauge section using tungsten carbide alloy that makes wear resistance and protects the gauge well.
