The Wire Cup Brush delivers an excellent, fine-surface finish. It features crimped wire for light-to-medium-duty cleaning applications. It is suitable for removing coatings and rust and for cleaning formwork boards and facings. Ideal for use on steel surfaces, this brush is also suitable for roughing, mat 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 drills with a 6-mm shank.
