Mini buffing wheels are prized because they are accessible to get into tight areas. These smaller polishing wheels are able to go on an angle grinder and polish hard-to-reach areas like above a fuel tank that a full size buffing wheel might struggle to access. These buffing wheels still have a 5/8 arbor hole to utilized with an angle grinder or dedicated polisher.

Please consider using an extender as well to assist in polishing and from preventing rub on a polisher or angle grinder.
