Portable electric belt driven dental drill with tripodal feet made by Kaltenbach & Voigt, Germany circa 1950s. Used by the Auckland School Dental Service from the 1960s and disposed in the 1980s as surplus stock. The drill was driven by an external motor (which is missing from this unit) and the speed of the drill was modulated by foot. The drill handpiece was fitted with replaceable metal tipped dental burs of different shapes.
