The Kerr TF (Twisted File) is a rotary nickel-titanium endodontic file designed for root canal preparation. It features R-Phase heat treatment technology and a twisted, non-ground design that preserves grain structure, reducing microfractures and increasing flexibility and resistance to cyclic fatigue. The TF technique requires only three files per case, improving clinical efficiency and reducing chair time.
