Built with stainless steel fill material, it delivers rust-free performance on materials where carbon steel contamination must be avoided. The brush runs at a maximum of 20,000 RPM and carries a fine grade designation, making it effective for deburring, weld cleaning, and scale removal on confined surfaces. The 3\/4-inch brush diameter keeps the working footprint small, allowing access to recesses, ports, and bores that flat or cup brushes cannot reach. This tool is sold individually and does not include a shank.\u003c\/p\u003e\n\u003cp\u003eThis end brush is suited for use in fabrication shops, maintenance environments, and field service applications where stainless steel contact surfaces must stay free of ferrous contamination. It mounts to a rotary tool, die grinder, or drill press via a separate shank. Typical users include welders, pipefitters, machinists, and maintenance technicians working on stainless steel pipe, tubing, and fittings. The knotted wire construction provides greater cutting aggression than crimped wire at equivalent diameters, making it a practical choice for removing tight mill scale or weld spatter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnotted wire construction for aggressive cutting action on hard-to-reach surfaces\u003c\/li\u003e\n  \u003cli\u003eStainless steel fill material prevents ferrous contamination on stainless workpieces\u003c\/li\u003e\n  \u003cli\u003e20,000 RPM maximum rated speed compatible with standard die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch brush diameter sized for access to confined bores, ports, and recesses\u003c\/li\u003e\n  \u003cli\u003eFine grade wire in the 0.0101 to 0.0200 inch diameter range\u003c\/li\u003e\n  \u003cli\u003eNo shank included — mounts to a separately sourced arbor or chuck\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style end brush for use with rotary tools, die grinders, and drill presses that accept standard end brush arbors or shanks; no shank is included with this brush.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified operator familiar with rotary abrasive tooling. Always confirm the spindle speed of the host tool does not exceed the 20,000 RPM maximum rating of this brush before mounting. Wear ANSI-rated eye and face protection as required by OSHA 1910.133 when operating wire brushes at speed. Inspect the brush for bent or broken wires before each use and replace if damage is found.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 3\/4 inches\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\u003eFilament\/Wire Diameter Range\u003c\/strong\u003e: 0.0101 to 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: OSBORN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0003043400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSBORN","offers":[{"title":"Default Title","offer_id":51734953263410,"sku":"0003043400","price":32.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cf9e1d7b3a69d85c878d11e1f87ce90_799ab3b1-e9c7-411f-86c7-d43fceb319ce.jpg?v=1788768507","url":"https:\/\/voomisupply.com\/products\/osborn-0003043400-knotted-wire-end-brush-3-4-in-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
