We produced the coal mining series which introduce advanced technology,combined with non-planar diamond layer and carbide interface ,greatly improve the impact resistance and thermal stability of PDC; it is suitable for soft to medium hard geological rock formation especially, which has a strong impact,fast drilling speed, timeliness and high resistance and mainly used in the manufacture of coal mines with PDC bits.
