Abstract: A stone polishing head for use on a conventional automatic polishing machine which is simple, but has the weight and strength of a prior art polishing head for which the machine was designed. The polishing head is formed of a solid steel barrel having a central bore for coolant flow. On the bottom surface of the barrel a first plate is fixed, and a drive plate is resiliently fixed adjacent to the plate. A tool carrier plate is releasably fixable to the drive plate for rotation with the barrel. The plates are connected by a plurality of connecting pins to maintain the plates parallel to each other.
