It features a 0.5-inch brush diameter with stainless steel crimped wire filaments rated up to 0.0100 inch in diameter. The 6 mm steel shank mounts directly into a rotary tool, die grinder, or drill, making it a practical tool for HVAC technicians, pipefitters, welders, and machinists working on metal surfaces. It is rated to a maximum of 25,000 RPM, supporting high-speed applications where a standard brush would fall short.\u003c\/p\u003e\n\u003cp\u003eThis end brush suits metal cleaning, weld prep, rust and scale removal, and light deburring on ferrous and non-ferrous work surfaces. The stainless steel fill material resists contamination on stainless or aluminum workpieces, which is important when cross-contamination from carbon steel bristles is a concern. Its compact 0.5-inch diameter fits confined spaces such as tube interiors, weld joints, and close-tolerance fittings commonly found in HVAC, plumbing, and light fabrication work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5-inch brush diameter for use in confined or hard-to-reach areas\u003c\/li\u003e\n  \u003cli\u003eStainless steel crimped wire fill resists contamination on sensitive base metals\u003c\/li\u003e\n  \u003cli\u003eWire filament diameter up to 0.0100 inch for flexible, even contact\u003c\/li\u003e\n  \u003cli\u003e6 mm steel shank included, compatible with standard die grinder and rotary tool chucks\u003c\/li\u003e\n  \u003cli\u003e25,000 RPM maximum speed rating supports high-speed power tool operation\u003c\/li\u003e\n  \u003cli\u003eNo pilot, bridle, encapsulation, or hollow center — straightforward end brush configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard end brush for use with die grinders, rotary tools, and electric drills fitted with a 6 mm compatible chuck or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by trade professionals including pipefitters, welders, and HVAC technicians using standard die grinders or rotary tools. Before mounting, confirm the tool chuck or collet accepts a 6 mm shank and verify the tool RPM does not exceed the 25,000 RPM rating of the brush. Always wear appropriate eye protection and a face shield when operating wire end brushes at speed. Inspect the brush for damaged or splayed filaments before each use and remove from service 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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Crimped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilament Diameter\u003c\/strong\u003e: Up to 0.0100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 25,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191521\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: WEILER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 90300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51541756117298,"sku":"90300","price":34.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d9b2aa8ef343367f79bc495d55357f5.jpg?v=1785884124","url":"https:\/\/voomisupply.com\/products\/weiler-90300-end-brush-1-2-in-stainless-steel-crimped-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
