The brush measures 5 inches in diameter and runs a single row of knotted steel wire at 0.0314 inches wire diameter, delivering a coarse cutting action that clears heavy deposits efficiently. It is rated to a maximum of 6,500 RPM and mounts via a 5\/8-11 threaded arbor, making it compatible with standard right-angle grinders used in fabrication, maintenance, and industrial trades.\u003c\/p\u003e\n\u003cp\u003eThis cup brush is suited for use in metal fabrication shops, structural steel work, pipeline maintenance, and general industrial applications where heavy burr removal, rust stripping, or surface conditioning is required before welding or coating. The knotted wire configuration provides greater aggression than crimped wire brushes, making it a practical choice for coarse-grade work on ferrous metals. It is sold individually and fits grinders equipped with a 5\/8-11 spindle thread.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnotted steel wire fill for aggressive, coarse-grade surface preparation\u003c\/li\u003e\n  \u003cli\u003e5 inches brush diameter for broad contact coverage on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003e0.0314 inches wire diameter provides high stiffness and cutting force\u003c\/li\u003e\n  \u003cli\u003eSingle-row construction for concentrated wire density\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor mounts directly to standard right-angle grinders\u003c\/li\u003e\n  \u003cli\u003e6,500 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or jobsite-supply cup brush for right-angle grinders with a 5\/8-11 threaded spindle.

Before mounting, disconnect the grinder from its power source and confirm the tool spindle speed meets or exceeds the brush RPM rating. Thread the brush firmly onto the 5\/8-11 arbor and verify it is fully seated before restoring power. Always wear appropriate PPE including face shield and gloves when operating wire cup brushes, and never exceed the marked maximum RPM.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0314 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Type\u003c\/strong\u003e: Knotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRow Count\u003c\/strong\u003e: Single Row\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Type\u003c\/strong\u003e: Threaded Arbor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 6,500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrim Length\u003c\/strong\u003e: 24 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S04185898\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722981179698,"sku":"S04185898","price":56.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40eefd5d828ce1a755b7391476439125.jpg?v=1788598808","url":"https:\/\/voomisupply.com\/products\/value-collection-s04185898-cup-brush-5-in-knotted-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
