Mounted via a 1\/4-inch shank included with the brush, it installs directly into a die grinder for fast material removal. The 13C130 is rated to 25,000 RPM, making it suitable for high-speed finishing passes without sacrificing brush integrity. Cable-twist wire knots deliver concentrated, consistent contact across the work surface. The 2-3\/4-inch outside diameter and 3\/8-inch face width provide a narrow, focused cleaning path suited to welds, joints, and tight profiles. HVAC fabricators, pipefitters, ironworkers, and sheet metal mechanics are the typical end users for this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThis wheel brush is built for use on steel surfaces and is compatible with die grinders accepting a 1\/4-inch shank. It is well suited to weld spatter removal, scale cleaning, surface deburring, and pre-weld joint prep on mild steel, structural steel, and similar ferrous materials. The cable-twist knot construction maintains wire tension under load, extending brush life in sustained grinding applications.
