Micro Drill Bits, Accessories, and Replacement Parts

This line-powered micro drill will make easy work of grinding, finishing, cutting and drilling bone, teeth and other material. The high-torque 35,000 rpm (maximum) motor is quiet and has minimal vibration which reduces wear on the motor and provides greater comfort for you. It also features a forward and reverse switch, “E Type” handpiece and handpiece holder. The handpiece has a removable nose cone that can be cleaned and sterilized. It accepts 3/32” and 2.33mm bur shanks. Unlike battery-powered drills, this unit maintains consistent power for the duration of use. The wide range of speeds allows you to control the amount of heat generation.
