The Clean for Metal Wire Cup Brush provides an extra-fine surface finish. The cup brush is fitted with crimped wire for light- to medium-duty cleaning applications. Ideal for use on metal, it is suitable for cleaning work on medium to large steel surfaces, such as removing coatings, rust and cleaning formwork boards and facings. The cup brush is also suitable for roughing, matt sanding and paint stripping. Brush wires are available in different thicknesses for variable levels of abrasive needs. Thicker wires are more aggressive, producing a coarser yet faster surface finish, while thinner wires deliver finer, smoother surface results. It is intended for use with angle grinders with an M14 thread.
