Cleaning rusted threads with a hand wire brush takes forever and lacks power. A wire wheel attachment turns a drill or bench grinder into a high-speed cleaning tool. It features hundreds of stiff steel or brass wires crimped or knotted together into a circular wheel. When spun at high RPM, the wire tips act like tiny chisels, scraping away rust, old paint, and scale without removing the base metal.
Always wear safety glasses and thick leather gloves when using a wire wheel. As the tool spins, it throws off loose wire bristles at high speeds. These sharp needles can easily pierce your skin or eyes. Hold the work piece firmly, and avoid pushing too hard against the wheel, as excess pressure will bend the wires and make the tool less effective.
