Clinical Tip

NIC positions KD Blue as its alternative for Vortex Blue users — matching the 500 RPM speed and a 15-50 .04/.06 size matrix with graduated per-file torque (0.75-3.6 Ncm), documented by the manufacturer's fact sheet, draft IFU, and catalog only. Choose Vortex Blue for the extensively studied original with published blue-wire metallurgy and independent performance data.
