    Air turbine hand pieces can run up to 500,000 rpm, although they are rarely used at such high speeds. General operating speeds are 20,000–50,000 rpm varying with the diameter of the bur. The burs used at high speeds are mainly diamond coated or made of tungsten carbide. High speeds are used in the removal of enamel, dentine, and old fillings.
