1308 PDC Cutters For Geological Mining With High Wear Resistance

1. PDC- Polycrystalline Diamond Compact Introduction

PDC- Polycrystalline diamond compact is composed of polycrystalline diamond layer and tungsten carbide substrate, the polycrystalline diamond layer possesses extremely high hardness and abrasion resistance whereas the tungsten carbide substrate would greatly improve the malleability and weld ability of the whole composite, the polycrystalline diamond compost is used oil well drilling petroleum, geology exploring, coalfield mining and mechanical industry.
PDC cutters for geological mining field drilling bits series are designed for markets in the pursuing of cost. This series PDC are mainly used for producing anchor-shank drill bits, which are equipped with sharp edge, fast footage, high effectiveness, stability, economical and practical advantages.
