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.
