1/ longer using life: take PDC inserts as main cutters, it's using life is 10 times more than carbide, 4 to 5 times of normal diamond drill bit.
2/ high drilling efficiency: large outcropping of diamond (composite polycrystal line layer almost entirely exposed), the drill can remain very sharp all the time, thus greatly improving the speed of the drill.
3/ can make drilling in low pressure, low rotary speed, and broke rock through scratch and cutting, pressure of drilling just need 1/3 of impregnated diamond core drill bit in same diameter.
4/ Excellent gage effect: our company PDC drill bit be mounted with polycrystalline diamond inside and outside to make good gage, good wear resistance, guaranteed good gage performance, make efficient usig of the cutting teeth.

5/ Due to the high drilling speed, long using life, thus drilling costs are greatly reduced, cost effective.
6/ widely used range suitable carbonate rock, limestone, chalk, clay, siltstone, sandstone and other soft, medium and hard (can drill rock below 9 degree) stratigraphic drilling, compared to normal drill bit, especially drilling of 6-8 degree, the effect is particularly significant.
