BRM's carbon steel circular flare end brushes are available from 1"-4" and are ideal for removing rust and paint; polishing; mold cleaning; deburring and spot facing. Circular flare end brushes provide side cutting action and will not score blind hole bottoms. 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. 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.
