PDC Drill Bits are applied to rock formation f below 12, like granite, limestone, sandstone, mudstone, etc., mainly used for gas drainage hole, drainage hole, grouting hole, geological and hydrology drilling.
Usually drag bits are three wings or four wings.
Our drill bits adopt 2 cutters, flat and dome-shaped cutters,
The flat cutters have high abrasion resistance and fast drilling efficiency, suitable for drilling ordinary formation.
The dome-shaped cutters have high impact resistance and stable drilling performance, suitable for formations with hard interned layers.
