The carbide inserts maintained their sharpness far longer than expected, giving us a fantastic ROP through abrasive sandstone. We finished the hole in record time.

We've put over 200 hours on this bit in a tough formation, and the loss rate is virtually zero. The build quality and weld integrity are outstanding.
