The Heavy for Metal Wire Cup Brush provides an extra-coarse surface finish. This cup brush is fitted with knotted wire for heavy-duty cleaning applications. Ideal for use in metal, it is suitable for cleaning work on medium to large steel surfaces, such as removing heavy rust, underseal, paint or varnish. It is intended for use with angle grinders with an M14 thread.

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.
