The K3XF Nickel-Titanium rotary file is an endodontic instrument featuring a heat-treated, twisted, triangular shank with moderate stiffness and a variable pitch for efficient coronal debris removal. Its third radial land enhances centering for improved control and stability, while proprietary R-Phase Technology provides exceptional flexibility and resistance to cyclic fatigue. This file is color-coded red, size #25, with a .06 taper and 21 mm length, and is part of a system with matching obturators, verifiers, gutta-percha, and paper points.
