- 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.
