The Kerr K3XF NiTi rotary file is a third-generation asymmetric endodontic instrument designed for efficient and safe root canal preparation. Featuring proprietary R-Phase Technology, it offers superior flexibility and two times more resistance to cyclic fatigue compared to conventional files. The self-centering design with a third radial land minimizes transportation, while variable pitch enhances control and coronal debris removal. Each pack contains six files, size #40 with a .08 taper, 25mm length, color-coded black.
