We tried every diamond bit manufacturer we could, and at the end of the day, the new Diaset UltraTerra Precision core bits were the best, by at least 10%. Measured using bit life, and penetration rate.
Diaset reaming shells, full hole adaptor couplings and full hole carbide/adiamond locking couplings, as a system, have been proven to keep our drill holes on target, within 1/2 degree on dip. Plus, Diaset reaming shells last 50% longer than what we were using.
We did indeed get to use the Diaset bits and we are very fond of them. Tough, resilient, steady cutting…. They get through the hardest rock -- we drilled iron formation and intensely silicified rock successfully. …. Very pleased.
