TF Twisted Files NiTi Rotary File, .04 Taper, 27mm, Size #40, Black, 3/Pk, 822-4407
The TF (Twisted File) is a rotary nickel titanium endodontic file used for root canal preparations. Its cutting flutes are created by twisting rather than grinding, which preserves grain structure and reduces microfractures for greater strength and durability. R-Phase heat treatment technology optimizes flexibility and resistance to cyclic fatigue, while a special surface conditioning treatment finishes the file without compromising the grain structure. This size #40 file has a .04 taper, 27mm length, and is color-coded black; each pack contains 3 files.
