The wheel measures 7 inches in diameter and 1\/2 inch thick with a 1-1\/4 inch arbor hole. A 60-grit medium-grade abrasive and J hardness code deliver an efficient balance of stock removal and wheel life. Maximum operating speed is 3,600 RPM. This wheel is a fit for surface grinders, cylindrical grinders, and CNC cutting tool machines used in production and job-shop environments. Installation and use should be performed by qualified grinding machine operators following applicable ANSI B11 and OSHA abrasive-wheel standards.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface and cylindrical grinding operations on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its vitrified bond provides consistent performance across these materials in both light-duty finishing passes and moderate stock-removal cycles. The non-porous, non-tapered, non-recessed Type 1 straight profile is the most common wheel geometry for horizontal-spindle surface grinders found in machine shops and maintenance facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60-grit aluminum oxide abrasive for medium stock removal on steels and irons\u003c\/li\u003e\n  \u003cli\u003eJ hardness (medium grade) vitrified bond — Series 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e3,600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-tapered, non-recessed Type 1 straight wheel profile\u003c\/li\u003e\n  \u003cli\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines\u003c\/li\u003e\n  \u003cli\u003eSuitable for 400 series stainless, carbon steels, tool steels, aluminum, and cast and ductile iron\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the grinding machine before mounting or removing a wheel. Inspect the wheel for cracks or chips using a ring test before installation and never exceed the marked maximum RPM of 3,600. Follow ANSI B11.9 and applicable OSHA 29 CFR 1910.215 requirements for abrasive wheel guarding and machine setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 60J8V32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue \/ Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 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: 66253246820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542334079282,"sku":"66253246820","price":49.06,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a11d42b0cf2369b3a0e407a9ff1c506.jpg?v=1785898498","url":"https:\/\/voomisupply.com\/products\/norton-66253246820-surface-grinding-wheel-7in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
