Centering Post Assembly

Abstract

A centering post assembly includes an adapter that has a coupling section, a receiver section and a disk section extending between the coupling section and the receiver section. The coupling section has a pre-determined diameter for inserting into a bolt hole in a backing plate of an angled power tool. The receiver section has a pre-determined diameter for inserting into a center hole of a polishing pad thereby facilitating the polishing pad to be centered on the backing plate. The disk section is strategically positioned between the coupling section and the receiver section to extend a pre-determined distance into the bolt hole in the backing plate.
