Developed to give customers easy access to information, the Tercel iTool is invaluable. It provides hydraulic calculation for bits in both international standard units and imperial units; it calculates TFA, pressure drop, jet velocity, internal nozzle size and HHP created at a nozzle orifice during drilling operations. The app also features interactive guides to the IADC Classification and Dull Grading systems for fixed cutter bits. The app is available through iTunes.
