Coastal GeoThermal

Coastal Geothermal has been designing and installing GeoExchange systems in Eastern North and South Carolina for over 10 years. Drilling in the sandstone of this region has traditionally been done using drag bits and tricone bits. 

Mike Hadley, a certified GeoExchange designer and president of Coastal Geothermal, decided to try the Diamond Devil PDC bit. To his amazement, the bit drilled faster, consumed less fuel, and lasted longer than the other types of bits. 

Below is a photo of the Diamond Devil PDC that he returned to Palmer Bit Co. to have repaired.  After an astonishing 72,000 feet of drilling on this bit, you can see the level of wear and the diamond cutters are still mostly intact. Coastal Geothermal is sold on the Diamond Devil PDC because of the significant positive impact it has made on their bottom line. You can try one too.
