Mounted via an arbor hole, it attaches to bench grinders, angle grinders, and similar rotary tools. The brush features a 4-inch outside diameter and a carbon steel fill, delivering the wire tension and bite needed for heavy-duty deburring and surface conditioning tasks. Rated to 20,000 RPM, it is suitable for high-speed applications where throughput and cut rate matter. Metalworking fabricators, welders, and industrial maintenance technicians are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis wheel brush is suited for metal fabrication shops, maintenance and repair operations, and structural steel work where consistent weld prep and surface cleaning are required. The knotted wire construction produces a more aggressive cutting action compared to crimped wire, making it appropriate for removing heavy mill scale, slag, and rust from steel and iron surfaces. It is sold individually and does not include a shank adapter.\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 cleaning\u003c\/li\u003e\n  \u003cli\u003e4-inch outside diameter with a 5\/16-inch face width for focused contact area\u003c\/li\u003e\n  \u003cli\u003eArbor hole mount accepts 1\/2-inch and 5\/8-inch arbor sizes for broad grinder compatibility\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM for use on high-speed bench and angle grinders\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch trim length provides wire flex and durability during extended use\u003c\/li\u003e\n  \u003cli\u003eFilament wire diameter in the 0.020 to 0.029-inch range for heavy-duty cut rate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with bench grinders and angle grinders accepting 1\/2-inch or 5\/8-inch arbor hole mounts.
