A third-generation driller ordered two Diamond Devil PDC's for a job in Cotulla, TX knowing the conditions called for PDC drilling. He called back to the shop to inform his dad he was getting two holes a day.

"It's impossible to get two holes a day in those conditions! I'm coming down to see." Sure enough, the Diamond Devil PDC doubled the production on those 400' holes.

The Diamond Devil PDC drilled top to bottom through blue clay, sandstone and dolomite. He later used the bit in Marble Falls under similar conditions with great success.
