PDC bit has a long working life,  very fast penatration and high percentage core recovery in soft to hard rock formations.
 
Because of the polycrystalline diamond cutters set on the crown, PDC bit has a long working life, very fast penatration and high percentage core recovery in soft to hard rock formations. PDC bit may be used with air, mud, or foam flushing.
 

PDC bits are recommended for coring soft to medium hard formations, with water, air, mud or foam as the flushing medium. It is ideal for air flush applications where a high rate of production is required.

It has extremely fast penetration rates and a very long working life. The cutters are extremely tough and can core formations such as hard limestones with occasional bands of harder rock such as ironstone.

It has been proved to be exceptionally cost effective for geotechnical drilling.
