178mm diameter x 25mm width x 32mm bore, 0.3mm Wire length The all-round brush for medium to heavy brush applications. Multiple row brushes are best for treating larger surface areas because of their wider face width. A special advantage of these brushes is the added choice of adaptors to fit most popular spindle diameters. The brass coating is much less likely to be aggressive, this allows it to gently remove rust, paint, or contaminants, but is soft and pliable enough to do so without scratching or damaging the metal underneath.
