    2017-10-17 · Active speed is the actual speed the turbine is reduced to when the bur contacts the tooth structure (bur is actively engaged against the tooth). Most air rotors have an active speed in the range of 180,000 to 200,000 rpm (about half of the free speed) depending on the contact pressure. This is where the torque of the handpiece comes into picture.
