The Kerr TF (Twisted File) is a rotary nickel-titanium endodontic file designed for root canal preparation. It features R-Phase heat treatment technology for enhanced flexibility and resistance to cyclic fatigue, and its twisted, non-ground design preserves grain structure to reduce microfractures. The advanced surface conditioning treatment ensures efficient cutting and safe canal shaping, typically requiring only 3 files per case.
