The Pencil Brush provides a good fine surface finish. It is fitted with crimped wire for light- to medium-duty cleaning applications on small steel surfaces. Its shape makes it ideal for cleaning work in very hard-to-reach areas such as in corners and the inside of pipes and profiles. The pencil brush is also suitable for removing rust, 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 drills with a 6-mm shank.
