The DDS iTool is designed to provide TFA, pressure drop, jet impact velocity, internal nozzle, Hydraulic Horsepower created at a nozzle orifice, which is installed in a drilling bit during earth-boring operations that can easily be calculated from easily entered information by the user.

Input data includes nozzle flow area, flow rate, bit size and mud density. ISO and Imperial units can be selected.

DDS iTool also provides information on IADC Dull Grading and IADC Fixed cutter Bit classification (Version 1992). Nomenclature details are provided as well as those of other fixed cutter bits nomenclature. When possible, corresponding data field such as blade count or cutter size have been linked to all quick comparison of the main bit features.
