The polishing heads allow you to separate the face plate from the adapter so you can minimize cost and inventory you have to stock. Each polishing head disc comes with a sponge pad, three screws and a hex wrench. Simply screw the three screws using the provided hex wrench into the polishing head disc. Secure on the left or right shaft on a cabbing unit or arbor unit.

This is a two part system. Look at image for a better understanding. Disc and adapter are sold separately.
