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 (not ground) design preserves grain structure to reduce microfractures. The advanced surface conditioning treatment ensures efficient cutting and safer shaping, allowing most cases to be completed with just three files.
