NSK's N-75 high speed handpiece provides all the benefits of the NL-85 handpiece, but in a non fiber optic format. This includes ceramic ball bearings, the clean head system, ultra push chuck, and triple port spray. Ceramic turbine bearings provide quieter performance at high speeds, with less wear, resulting in greater reliability and dramatically increased turbine life. NSK precision micro machining capability ensures bur run out of less than .01 mm.
