Built with stainless steel fill wire in the coarse grade, it handles rust removal, weld spatter cleanup, scale removal, and surface conditioning on stainless or corrosion-sensitive substrates where carbon steel contamination must be avoided. The brush runs at up to 22,000 RPM and mounts via a 1\/4-inch diameter steel shank, making it compatible with die grinders and rotary tools used throughout fabrication, welding, and mechanical service work. Licensed tradespeople and skilled fabricators are the primary installers.\u003c\/p\u003e\u003cp\u003eThis end brush is suited for tight access areas, inside bores, pipe ends, weld joints, and confined surface areas where a cup or wheel brush cannot reach. The knotted wire construction delivers high-impact scrubbing action appropriate for heavy deposits on steel, stainless steel, and similar hard metals. At 1 inch brush diameter with a 1-1\/2 inch shank length, it fits standard die grinder collets and is commonly used in industrial maintenance, HVAC sheet metal work, pipe fitting, and structural steel fabrication.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKnotted stainless steel wire for aggressive, contamination-free surface prep\u003c\/li\u003e\n\u003cli\u003eCoarse grade fill delivers high-impact cleaning action on heavy scale and spatter\u003c\/li\u003e\n\u003cli\u003e22,000 RPM maximum speed rated for use with pneumatic and electric die grinders\u003c\/li\u003e\n\u003cli\u003e1\/4-inch pilot shank fits standard die grinder collets without adapters\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch shank length provides reach into recessed or confined work areas\u003c\/li\u003e\n\u003cli\u003eNon-bridled, non-encapsulated, non-flared construction for open wire contact\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement end brush for use with standard 1\/4-inch collet die grinders and rotary tools rated to handle accessories at 22,000 RPM or higher.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, fabricators, pipefitters, welders, or HVAC technicians using a die grinder or compatible rotary tool. Always confirm the tool's rated speed meets or exceeds the brush maximum RPM before mounting. Wear appropriate PPE including face shield and gloves when operating wire brushes at speed. Inspect the brush for damaged or splayed wires before each use and replace if wire integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Knotted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 22,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilament\/Wire Diameter Range\u003c\/strong\u003e: 0.0101 to 0.0200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.32 x 2.88 x 1.33 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66252838887\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541191852338,"sku":"66252838887","price":22.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/762b9ae0d850795aab7bcc9ec34cf9db.jpg?v=1785869858","url":"https:\/\/voomisupply.com\/products\/norton-66252838887-end-brush-1-in-stainless-steel-knotted-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
