Built with a ceramic alumina abrasive and a resinoid bond, this wheel delivers a coarse 24-grit cut rated for use at up to 6,600 RPM. It measures 9 inches in diameter and 1\/8 inch thick, with a 5\/8-11 threaded hub that fits standard angle grinder spindles. The rigid, non-flexible construction keeps the wheel stable under load, making it well suited for weld grinding, surface prep, and heavy stock removal in fabrication, construction, and industrial maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on angle grinders in professional trade and industrial settings. The Type 27 raised-hub profile allows flat and flush grinding on plate steel, structural iron, weld beads, and similar ferrous workpieces. The 24-grit coarse grade removes material quickly, making it appropriate for rough grinding passes rather than finishing work. Metal fabricators, ironworkers, pipe fitters, and maintenance mechanics are the typical end users. The 5\/8-11 threaded connection is the standard mount for most 9-inch angle grinders in the trade.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 27 depressed center profile for flush and flat grinding applications\u003c\/li\u003e\n  \u003cli\u003eCeramic alumina abrasive for fast, aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003e24-grit coarse grade suited for weld grinding and heavy material removal\u003c\/li\u003e\n  \u003cli\u003eResinoid bond provides durability and consistent performance under load\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded hub fits standard 9-inch angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003eRigid, non-flexible construction for stable, controlled cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-mount replacement for 9-inch angle grinders equipped with a 5\/8-11 threaded spindle.

Always power down and disconnect the grinder before mounting or removing a wheel. Confirm the grinder spindle speed rating meets or exceeds 6,600 RPM and that the correct Type 27 guard is in place before operating. Follow ANSI B7.1 and applicable OSHA standards for abrasive wheel mounting, including the use of proper flanges and a blotter where required.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 27 Depressed Center\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Thread Size\u003c\/strong\u003e: 5\/8-11 Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 6,600 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.26 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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66252839431\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540460732722,"sku":"66252839431","price":280.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/216181feb1b505897779da9e1e6941b5.jpg?v=1785855880","url":"https:\/\/voomisupply.com\/products\/norton-66252839431-type-27-grinding-wheel-9in-24-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
