K3 is a third-generation, triple-fluted, asymmetric nickel-titanium rotary endodontic file system designed to cut quickly, efficiently, and safely with exceptional debris removal. Its positive rake angle provides active cutting action, while the wide radial land adds peripheral strength to resist torsional and rotary stresses and the third radial land keeps the instrument centered in the canal to minimize over-engagement. This 25 mm, .04 taper, #20 (yellow) file comes in a package of 6 (Kerr reference 825-4205).
