The 1-inch brush head uses 0.020-inch wire diameter and is built with an internal holding plate that maintains wire position during operation, promoting consistent performance and reducing safety risk from wire throw. The 1\/4-inch stem arbor fits standard rotary tools and die grinders, and the brush is rated to a maximum speed of 20,000 RPM. Each unit is 100% wire-inspected to meet strict quality specifications. This brush is part of a 5-piece package.\u003c\/p\u003e\n\u003cp\u003eThe DW4902 is suited for metal deburring, weld bead cleaning, and surface preparation work in fabrication, maintenance, and repair applications. The knotted wire configuration delivers aggressive cutting action for stripping rust, scale, and heavy coatings from steel and other hard metals. It is a common choice for HVAC installers, pipefitters, and metal fabricators who need consistent bite on tight or hard-to-reach surfaces where a cup brush will not fit. The 1\/4-inch stem makes it compatible with most pneumatic and electric die grinders used in trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnotted carbon wire construction for heavy-duty material removal\u003c\/li\u003e\n  \u003cli\u003eInternal holding plate maintains wire alignment and supports safe, balanced operation\u003c\/li\u003e\n  \u003cli\u003e100% wire inspection at the factory to meet demanding quality specifications\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch stem arbor fits standard die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003eSold as a 5-piece package for extended service use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-fit end brush for die grinders and rotary tools accepting a 1\/4-inch stem arbor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed tradespeople or experienced users familiar with rotary tool safety. Always confirm the tool spindle speed does not exceed the 20,000 RPM rating of the brush before operation. Wear appropriate eye protection and gloves, as wire bristles can throw debris at high speed. Inspect the brush for damaged or missing wires before each use and replace if wire integrity is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Arbor Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Knotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 20,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\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: DEWALT ACCESSORIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DW4902\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51558721618226,"sku":"DW4902","price":45.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6334d681cf6271e8748ec81a40f9bed8.jpg?v=1786418911","url":"https:\/\/voomisupply.com\/products\/dewalt-accessories-dw4902-knot-wire-end-brush-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
