The DeWalt DW4917 6-inch knotted cup wire brush is built for contractors who demand heavy-duty surface prep on metal, concrete, or masonry. Made with tightly twisted carbon steel knots, this brush provides aggressive material removal while maintaining consistent performance under high RPMs. Its 5/8"-11 threaded arbor ensures secure mounting on grinders and rotary tools, allowing precise and efficient operation. Ideal for removing rust, paint, mill scale, and corrosion, the DW4917 DeWalt cup brush keeps work moving fast without sacrificing quality. Compared to standard brushes, the knotted design digs deeper into welds, corners, and irregular surfaces, giving a cleaner finish and longer life per brush. On tough job-site applications, the dewalt 6 inch knot wire brush stands up to repeated use, saving time and reducing downtime on prep work.
