The MDK handpieces are dental hand pieces for use by a trained professional in the field of general dentistry.

The MDK handpieces are hand-held, channeled instruments that are powered by compressed air delivered through a hose to an air channel in the handpieces. This impels the turbine in the head of the handpiece to revolve. The bur of the high speed handpieces can rotate up to 400,000 rpm and the bur of the low speed handpieces can rotate up to 100,000 rpm. Dental burs (not part of this 510k) can be inserted into the chuck system of each handpiece (push button, latch, screw, snap-on or tip-lock chuck options).
