In horseshoeing, buffing wheels and polishing compounds are primarily used on a motorized buffer or bench grinder to sharpen, maintain, and polish farrier tools - specifically hoof knives and rasps - rather than being applied directly to the horse's hoof.
Anvil Brand carries a variety of buffing wheels and compound products, including muslin, grooved felt wheel, buffing/sharpening wheel, and various compounds.
This product generally comes in a size of 6" and is usually used for grinding shoes and sharpening knives.
