Carbon Steel solid wire end brushes are ideal for rust and paint removal; weld; scale and slag removal; carbon cleaning; polishing dies; deburring and more. These brushes are used on high speed portable hand-held power tools to effectively clean and provide proper surface finishing for a variety of applications. They are a great solution for addressing recessed areas and smaller surfaces. The brush has a ¼” steel shank for quick mounting into a chuck or collet of either an electric or pneumatic die grinder. Proudly made in the USA.
