Kerr Endodontics' M4 Safety Handpiece has several features designed to aid the endodontic practitioner in efficiently and effectively performing root canal therapy. The watch-winding, oscillating movement of this endo handpiece keeps the hand file "floating" in the canal. The operator controls coronal and apical pressures, while the M4 smoothly and efficiently "glides" the endo instrument through the canal. That's the "Safety" in the M4 Endodontic Handpiece.
10000 rpm speed
Mimics watch-winding motion
Greatly reduces fatigue
Compatible with most hand files
1. Compatible with most hand files. Both feature a specialized chuck compatible with most hand files.
2. Mimics watch-winding motion. The chuck has been designed to oscillate, mimicking the watch-winding motion used when hand filing.
3. Greatly reduces fatigue. With very little apical pressure, the file smoothly and efficiently "floats" down the canal. The operator controls the pressure without having to manually perform the watch-winding movement
