K3 ENG FILE .40/.06 21MM

K3 is a third-generation, triple-fluted, asymmetric endodontic file system. Positive rake angle provides the active cutting action of the K3 endo files. The K3 rotary file’s wide radial land provides blade support while adding peripheral strength to resist torsional and rotary stresses. The third radial land on K3 files stabilizes and keeps the instrument centered in the canal and minimizes over engagement. Radial land relief reduces friction on the canal wall.
