Products >> Micromotors / Handpieces >>Black Power Feature: Due to the new electronic circuit design, power consumption is minimized. Power losses are so small that no heat generation occurs Superb bur concentricity within 0.02 mm. Bur chatter and jumping has been eliminated. This allows more precise and smooth cutting and polishing.
