PDC Coring Bits

Brightway can design and produce 5-8 diamond PDC Coring Bits with straight blade and spiral blade. The 6″~17.5″ models have complete specifications and can be used for core suitable for medium soft formations. The PDC Coring Bits adopts high-quality TSP polycrystalline diamond sheets, which have high drilling stability and long service life.

The PDC core drill bit (polycrystalline diamond composite drill bit) uses high-quality TSP polycrystalline diamond chips, which have high drilling stability and long service life.

Advantages of Brightway PDC Coring Bits:

● Lower parabolic profile and medium cutter density are designed to core in the medium soft formation;
● High performance cutter of newest technology to enhances the caperbility to drill hard layers.
