K3 Nickel-Titanium Engine File, 25 mm, 0.04 Taper, # 25, Red, 6/Pk, 8254255

• Used for root canal preparation
• Features a unique, cross-sectional design
• Can negotiate even the hardest S-shape curves
• Resists torsional and rotary stresses

K3 NiTi rotary file features a unique, cross-sectional design that allows K3 files to become highly resistant to cyclic fatigue. The K3 file negotiates even the hardest to reach S-shaped curves with minimal or no canal deformation.

These third-generation files feature a three-fluted, asymmetrical endo file system that works to cut quickly, efficiently, and safely to guarantee a higher rate of debris removal.
