• 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.
  
  

 Adaptive Motion Technology is based on a patented, smart algorithm designed to work with the TF Adaptive file system. This technology allows the TF Adaptive file to adjust to intra-canal torsional forces depending on the amount of pressure placed on the file. This means the file is in either a rotary or reciprocation motion depending on the situation. The result is exceptional debris removal with our classic rotary Twisted File design and less chance of file pull-in with our Adaptive Motion Technology. Now that’s rotary when you want it and reciprocation when you need it.
