MIBRO's Wire Wheel Brush Set is designed for the aggressive removal of paint, rust, and scale from different woods and metals. These brushes are equipped to handle everything from large flat surfaces to the tightest corners, to ensure you get the job done. Fine wire brushes can be used for harder-to-reach applications, like corners and crevices, and on softer materials like aluminum. Coarse wire brushes are designed to handle heavier pressure jobs and harder materials. The crimped steel wire has a brass coating that is corrosion resistant and reduces sparking. Each brush has a 1/4 in quick-connect hex shank suitable for use with all drills, impact drivers, and die grinders.
