The metal mesh over the air supply helps prevent polishing powder and hairs from getting into the motor.
This model is an upgrade of the 9227C, long a bestseller for its reliability and ease of use. It maintains the original's well-balanced, lightweight body and wide speed range while further perfecting the details to achieve a more refined polish. The head of the polisher, which was originally metal, now has a protective resin cover to prevent scratches from accidental contact and so on. The distinctive loop handle now uses a soft grip, making it easier to handle.
