That's a poor excuse for a 6 inch wire cup brush. This is a 4 inch cup brush with very long wires so centrifugal force will stretch them out. The only problem is that you have to spin it at 6500 rpm to get 6 inches. Turning it slower will give you a smaller radius. That's half the price of a real six-inch brush, but also half the tool. The tool works just like a wire brush, but don't think you'll get 6 inches out.
