They feature a stronger, more robust inner cutting tip material and patented XtraSharp technology for superior cutting performance, longer region of lubrication and optimized dimensions. In addition, when powered by the D4000/D4000A arthro power console/arthro power console with irrigation pump, a Turbo feature enables you to toggle between oscillate and forward modes.
