The brush measures 3\/4 inches in diameter and accepts a 6 mm steel shank, making it compatible with standard collet-style rotary tool chucks. It is rated to a maximum of 22,000 RPM. Crimped wire construction provides flexibility and consistent surface contact, making this brush well suited for deburring, cleaning weld seams, removing rust and scale, and light surface blending on metal workpieces. The wire filament diameter falls in the 0.0101 to 0.0200 inch range, offering a balance of aggressiveness and surface finish control.\u003c\/p\u003e\n\u003cp\u003eThis end brush is used in metal fabrication shops, maintenance and repair operations, and general industrial settings. It is a standard hand-tool-side item installed by machinists, welders, pipefitters, and maintenance technicians. Typical applications include spot cleaning of weld joints, preparing metal surfaces before coating, and accessing tight or recessed areas where larger brushes cannot reach. The small diameter and end-brush geometry make it especially practical for interior corners, bores, and confined weld zones.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inches brush diameter for targeted, small-area surface work\u003c\/li\u003e\n  \u003cli\u003eCrimped steel wire construction for flexible, consistent contact\u003c\/li\u003e\n  \u003cli\u003e6 mm steel shank fits standard rotary tool and die grinder collets\u003c\/li\u003e\n  \u003cli\u003e22,000 RPM maximum speed rating for use with high-speed rotary tools\u003c\/li\u003e\n  \u003cli\u003eWire filament diameter range of 0.0101 to 0.0200 inches for moderate aggressiveness\u003c\/li\u003e\n  \u003cli\u003eNot bridled, flared, or encapsulated — straightforward wire end brush configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in rotary tools and die grinders equipped with a 6 mm collet.

Always confirm the tool's maximum RPM rating meets or exceeds 22,000 RPM before use, or operate at or below the brush's rated speed. Wear appropriate eye protection and follow ANSI B165.1 safety guidelines for power wire brushes. Inspect the brush for damaged or splayed wire before each use and replace if deformation is observed.\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\u003eWire Type\u003c\/strong\u003e: Crimped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Steel\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: 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: 22,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 90290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51540571455794,"sku":"90290","price":23.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b171f8db599b4c906629f5088124b7df.jpg?v=1785858749","url":"https:\/\/voomisupply.com\/products\/weiler-90290-end-brush-3-4-in-crimped-wire-steel-6mm-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
