Description
This is a complete overhaul kit for the classic Midwest Quiet-Air Standard handpiece. It replaces the moving parts of the handpiece head. The "Screw Type" designation refers to the bur retention mechanism, which uses a specialized bur wrench (bur tool) to manually tighten the chuck around the bur shank. Including the end cap ensures that the new turbine fits perfectly and that the back bearing is properly supported, which is often critical for minimizing noise and vibration in older handpieces.
