Kerr TF (Twisted Files) are rotary nickel titanium endodontic files for root canal preparation, combining R-Phase heat treatment with a twisted, non-ground flute design for superior strength and flexibility. The Large Assorted Pack contains three size 25 (red) files at 27 mm length, one each of 0.06, 0.08, and 0.10 taper, allowing efficient canal shaping with fewer files per case. The twisted design and advanced surface conditioning reduce microfractures and cyclic fatigue while preserving the natural canal anatomy.
