PDC for Coal Field Mining Drilling Bits Series.
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.
It also can be cut into pieces as per customers' requests.
