Dewalt Accessories DW4901 Crimped End Wire Brush

Product Description

The DEWALT ACCESSORIES DW4901 is a crimped end wire brush designed for light-duty surface preparation tasks including rust removal, paint stripping, and general cleaning on metal surfaces. Built with carbon wire and an internal holding plate, the brush maintains consistent balance across its full operating range. The crimped wire configuration provides flexibility, allowing the bristles to conform to irregular surfaces without aggressive gouging. Rated to a maximum speed of 20,000 RPM, it fits standard 1/4 inch die grinders and rotary tools via its 1/4 inch stem arbor. All wire is 100% inspected to meet quality specifications before shipping. Sold in a package of 5 brushes.

This brush is suited for maintenance technicians, fabricators, and general trades professionals performing light material removal, weld spatter cleanup, and surface prep on metal components. The 1 inch diameter head is well-suited for accessing tight weld joints, small bores, and confined areas where larger cup or wheel brushes cannot reach. The crimped wire construction is preferred over knotted wire when the goal is cleaning and finishing rather than aggressive stock removal, making it appropriate for work where surface integrity needs to be preserved.
