It measures 7 inches in diameter with a 1\/8-inch thickness and mounts via a 5\/8-11 threaded hub. The abrasive material is ceramic alumina at a coarse 24 grit, bonded with a resinoid bond and finished in black. Rated to a maximum of 8,600 RPM, this wheel is built for metalworking applications where fast stock removal is the priority. It is a rigid, non-flexible wheel suited to grinding welds, deburring castings, and shaping ferrous stock.\u003c\/p\u003e\u003cp\u003eThis wheel is used across fabrication shops, structural steel work, pipe grinding, and general metal preparation tasks. The coarse 24-grit ceramic alumina construction delivers a high cut rate on hard metals, making it appropriate for applications where surface finish is secondary to material removal speed. Licensed tradespeople including ironworkers, pipefitters, and fabricators typically use wheels in this specification class. It is compatible with standard angle grinders that accept a 5\/8-11 threaded spindle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 27 depressed-center profile keeps the grinding face angled for flat-surface contact\u003c\/li\u003e\n\u003cli\u003eCeramic alumina abrasive provides a high cut rate and extended wheel life on ferrous metals\u003c\/li\u003e\n\u003cli\u003eCoarse 24 grit for aggressive stock removal and weld grinding\u003c\/li\u003e\n\u003cli\u003eResinoid bond withstands heat and impact during heavy-duty grinding\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded hub fits the most common angle grinder spindle standard\u003c\/li\u003e\n\u003cli\u003e8,600 RPM maximum speed rating for use on standard 7-inch angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on angle grinders with a 5\/8-11 threaded spindle accepting a 7-inch Type 27 depressed center wheel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified operator familiar with abrasive wheel safety. Ensure the grinder is disconnected from power before mounting or removing the wheel. Verify the grinder spindle speed does not exceed the 8,600 RPM maximum wheel rating before operation. Inspect the wheel for cracks or damage prior to each use and follow ANSI B7.1 safety requirements for grinding wheel mounting and guarding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 7 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\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\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 8,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.73 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66252839429\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541826175282,"sku":"66252839429","price":221.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69e383b595ab0ace5a7dffd31fa66f79.jpg?v=1785886015","url":"https:\/\/voomisupply.com\/products\/norton-66252839429-type-27-grinding-wheel-7-inch-24-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
