Built with coarse carbon steel fill wire, this brush mounts to angle grinders via a 5\/8-11 threaded arbor hole and is rated for a maximum speed of 20,000 RPM. The 4.5-inch outside diameter and 0.5-inch face width make it a compact, high-speed tool suitable for removing rust, mill scale, weld spatter, and heavy coatings. Filament wire diameters fall in the 0.0200 to 0.0299 inch range, providing aggressive cutting action on ferrous metals. This brush is a standard consumable used by welders, pipefitters, ironworkers, and maintenance mechanics.\u003c\/p\u003e\n\u003cp\u003eThis wheel brush is suited for use on angle grinders in residential, commercial, and industrial settings. Typical applications include weld prep and post-weld cleanup, surface descaling, rust removal, and paint stripping on structural steel, pipe, and sheet metal. The knotted wire configuration concentrates wire tips for faster, more aggressive material removal compared to crimped-wire designs. No shank is included; the brush requires a grinder with a compatible 5\/8-11 threaded spindle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnotted carbon steel wire for aggressive surface removal and weld cleanup\u003c\/li\u003e\n  \u003cli\u003e4.5-inch outside diameter with 0.5-inch face width\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor hole for direct mount on standard angle grinders\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCoarse grade fill with wire diameter range of 0.0200 to 0.0299 inches\u003c\/li\u003e\n  \u003cli\u003e1-inch trim length for consistent brush contact through the wire life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders equipped with a 5\/8-11 threaded spindle.

Always verify the grinder spindle speed does not exceed the brush maximum RPM of 20,000 before operation. Power down and disconnect the grinder from its power source before mounting or removing the brush.
