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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnotted wire fill for aggressive deburring, rust removal, and scale cleanup\u003c\/li\u003e\n  \u003cli\u003e4-3\/8 inch diameter cup brush profile for broad surface contact\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor fits most standard angle grinders\u003c\/li\u003e\n  \u003cli\u003eSteel wire construction rated up to 6,500 Max RPM\u003c\/li\u003e\n  \u003cli\u003e0.0314 inch wire diameter for firm, durable cutting action\u003c\/li\u003e\n  \u003cli\u003eNo guard included — verify grinder guard compatibility before use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders and bench grinders equipped with a standard 5\/8-11 threaded spindle.
