The General Purpose Wire Brush Cup is designed for light to medium cleaning tasks, offering excellent performance for removing rust, paint, corrosion, and surface contaminants on both flat and slightly contoured surfaces. It is ideal for general metal preparation, automotive work, maintenance, and DIY projects, providing a balance between performance and affordability. For more demanding jobs, the Heavy Duty Wire Brush Cup delivers aggressive cleaning power with a denser, stronger wire construction, making it suitable for removing heavy rust, thick paint, slag, scale, and weld splatter. It is specifically engineered for industrial applications such as fabrication work, shipbuilding, and structural steel maintenance where maximum strength and durability are required.
