Built with an aluminum oxide abrasive and a vitrified bond, this 7-inch diameter wheel operates at a maximum of 3,600 RPM and carries a medium-grade, I-hardness rating. The vitrified bond provides rigidity and open structure for consistent cut rates, making it a reliable choice for surface grinder work in production and tool-room environments. Licensed HVAC and mechanical trades as well as industrial maintenance machinists are the typical end users for this wheel type.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding applications on a range of materials including 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is rated for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The 1-1\/4-inch arbor hole fits standard spindle configurations common to benchtop and floor-standing surface grinders found in machine shops and maintenance facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for versatile metal grinding across ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction delivers consistent grain exposure and predictable wear\u003c\/li\u003e\n  \u003cli\u003eMedium grade, I-hardness (60I8V32A spec) balances aggressive cut with wheel longevity\u003c\/li\u003e\n  \u003cli\u003eNon-tapered, no-recess Type 1 straight profile for flat surface and OD grinding\u003c\/li\u003e\n  \u003cli\u003eRated to 3,600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines\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 equipped with a 1-1\/4-inch arbor.

Always confirm the machine spindle speed does not exceed the 3,600 RPM maximum rating marked on the wheel before mounting. Inspect the wheel for cracks or chips using the ring test before each use and never force the wheel onto the spindle. Power down and lock out the grinder before changing wheels.\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: 0.25 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: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Specification\u003c\/strong\u003e: 60I8V32A\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\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\u003eSeries\u003c\/strong\u003e: 32A Type 1\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: 66253246722\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542258647346,"sku":"66253246722","price":45.01,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e56583d01be7639675795270ee1d329.jpg?v=1785896593","url":"https:\/\/voomisupply.com\/products\/norton-66253246722-surface-grinding-wheel-7in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
