Built with carbon steel stringer bead twist wire, it mounts via a 5\/8-11 threaded arbor and spins at up to 12,500 RPM. The 6-inch outside diameter and 3\/16-inch face width concentrate cutting action into a narrow contact zone, making it effective for cleaning weld seams, deburring edges, and removing rust or mill scale. Fabricators, ironworkers, and maintenance technicians reach for this brush when a flap disc or grinder cup wheel is too broad for the task at hand.\u003c\/p\u003e\n\u003cp\u003eThis wheel brush is suited for use on angle grinders and bench grinders equipped with a 5\/8-11 threaded spindle. Typical applications include structural steel fabrication shops, pipe fitting, heavy equipment maintenance, and industrial MRO environments where consistent weld bead cleanup and surface conditioning are part of the daily workflow. The knotted wire construction delivers a more aggressive cut than crimped wire, making it the right choice for heavy deposits of slag, spatter, or oxidation on carbon steel and iron substrates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnotted stringer bead twist wire for aggressive material removal\u003c\/li\u003e\n  \u003cli\u003eCarbon steel fill material rated for ferrous metal applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor mount — no shank included, mounts direct to grinder spindle\u003c\/li\u003e\n  \u003cli\u003e6-inch outside diameter with 3\/16-inch face width for focused contact\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-inch trim length provides consistent wire projection and flex\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 12,500 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders and bench grinders fitted with a 5\/8-11 threaded spindle.

Always power down and disconnect the grinder before mounting or removing the brush. Verify the tool spindle speed does not exceed the brush maximum of 12,500 RPM before operation. Always wear face shield, safety glasses, and appropriate hand protection when operating knotted wire brushes, as wire filaments can break free during use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrim Length\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Knotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Knot Type\u003c\/strong\u003e: Stringer Bead Twist\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilament Wire Diameter Range\u003c\/strong\u003e: 0.0200 - 0.0299 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 12,500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Threaded\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: 1.15 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: 94664\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51540290732338,"sku":"94664","price":9503.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7662c17c297335b77fe49b38748772a.jpg?v=1785851327","url":"https:\/\/voomisupply.com\/products\/weiler-94664-knotted-wheel-brush-6-inch-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
