Featuring a new generation cellular optics, triple water spray and ceramic ball bearings, NSK's NL-85 sets a new standard for stainless steel high speed handpiece. NSK's cellular glass optics delivers 20% brighter illumination than conventional fibre optics and will not deteriorate from repeated autoclaving. Ceramic ball Bearings are 25% harder than stainless steel bearings, but just half the weight. Lower friction results in quieter and heatless operation, especially at high speed, and substantially longer turbine life.
