PDC Core bits incorporating Polycrystalline Diamond Cutters can be very cost effective and very productive in certain formations. PDC core bits have proved to be exceptionally cost effective for geotechnical drilling.

PDC core bits have 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.

Advantages:

· fast penetration,strong abrasion resisitance

· Good  performatnce for rock formations
