Kerr TF Twisted Files Rotary NiTi Endodontic File, .04 Taper, #40, 23mm, Black, 3/Pk, 822-4403
Kerr TF (Twisted Files) are rotary nickel-titanium endodontic files for root canal preparation, featuring R-Phase heat treatment technology that optimizes strength and flexibility. The cutting flutes are twisted rather than ground, eliminating micro-fractures and preserving the grain structure for greater durability and resistance to cyclic fatigue. Each pack contains three 23mm files with a .04 taper and #40 tip, color-coded black, and the TF technique typically requires only three files per case.
