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.
