Value Collection S04185831 Knotted Wire Cup Brush 4-3/8 in

Product Description

The VALUE COLLECTION S04185831 is a knotted wire fill cup brush designed for aggressive surface preparation and metal cleaning tasks. Built with a steel wire fill and a 5/8-11 threaded arbor, it mounts directly to standard angle grinders and bench grinders used in fabrication, welding, and maintenance shops. The brush measures 4-3/8 inches in diameter and is rated for up to 6,500 RPM, making it suitable for heavy-duty deburring, rust removal, scale removal, and weld spatter cleanup. The knotted wire construction delivers more aggressive cutting action compared to crimped wire, which is appropriate for harder base materials and thicker surface contaminants.

This cup brush is well suited for use in industrial maintenance, metal fabrication, and general mechanical service environments. It is commonly used by welders, pipefitters, ironworkers, and maintenance mechanics who need consistent material removal on ferrous metals. The 5/8-11 threaded arbor is a standard fitting that accommodates most 4-inch to 5-inch angle grinders. No guard is included with this brush.
