Measuring 6 inches in outside diameter with a 1\/2 inch face width and 1-3\/8 inch trim length, it mounts via a 5\/8 inch arbor hole to angle grinders and bench grinders. The carbon steel knotted wire construction with a standard twist knot pattern delivers high-impact abrading action at speeds up to 9,000 RPM. It is a standard tool in metal fabrication, welding, and industrial maintenance applications where fast stock removal or surface conditioning is required.\u003c\/p\u003e\n\u003cp\u003eThis wheel brush is suited for use on ferrous metals in fabrication shops, structural steel work, pipe preparation, and weld joint cleanup. The knotted wire configuration concentrates wire ends at contact points, making it effective on heavily oxidized, scaled, or rough-welded surfaces. Typical users include welders, pipefitters, ironworkers, and industrial maintenance technicians working on steel components requiring surface prep prior to painting, coating, or inspection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6 inch outside diameter with 1\/2 inch face width for broad contact coverage\u003c\/li\u003e\n  \u003cli\u003eKnotted carbon steel wire with standard twist knot for aggressive material removal\u003c\/li\u003e\n  \u003cli\u003e9,000 RPM maximum rated speed for use with common angle grinders and bench grinders\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch arbor hole for direct mounting — no shank included\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch trim length provides consistent wire engagement and brush life\u003c\/li\u003e\n  \u003cli\u003eFilament wire diameter in the 0.010 to 0.019 inch range for heavy-duty abrading\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders and bench grinders that accept a 5\/8 inch arbor hole mount and operate at or below 9,000 RPM.
