The Kerr TF (Twisted File) is a rotary nickel-titanium endodontic file designed for root canal preparations. It features R-Phase heat treatment technology and a twisted, non-ground design that preserves grain structure, reducing microfractures and enhancing flexibility and durability. The file's advanced surface treatment and helical angle design allow for efficient, safe canal shaping, often requiring only three files per case.
