A non-woven cleaning wheel with a pin attachment is used for processing hard-to-reach areas: removing scale and burrs, cleaning edges and welds of parts and structures made of metal, stainless steel, non-ferrous metals, aluminum, wood, plastics, as well as grinding and finishing the surface. Black coral is the softest and most delicate option. They are ideal for removing paint from aluminium, stainless steel and non-ferrous metals.
