Believe it or not, my summer job as an engineering student in college was in a factory that made, among other things, small electric brushes like these. (We've also made wire brushes two feet in diameter and twenty feet long for steel mills etc.) So not much in my opinion, but enough for occasional home use. They are also certain that "the price is rightโ. A little bit of information that might be helpful. The wire ends of the wire brush become "bluntโ after a while. Simply flip the bit and it will cut like new again.
