Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and thermal stability during wet or dry grinding operations. It measures 7 inches in diameter and 1-1\/4 inches thick, with a 1-1\/4 inch arbor hole and a 2-3\/4 inch recessed diameter on one side at 5\/8 inch recess depth. Rated at a maximum of 3600 RPM, the 60 grit, J-hardness (medium) specification suits moderate material removal on harder metals where surface finish and dimensional control matter.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on surface grinders and cylindrical grinders in machine shop, tool room, and manufacturing environments. Typical applications include tool steel reconditioning, carbon steel flat grinding, cast iron surface work, and light aluminum stock removal. The 32A series designation indicates a friable-free, porous aluminum oxide structure optimized for medium-grade grinding across a range of material hardnesses. Maintenance machinists, tool and die makers, and grinding machine operators are the primary installers and users of this wheel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut rate and wheel life\u003c\/li\u003e\n  \u003cli\u003eType 5 recessed one-side geometry reduces heat buildup and aids coolant delivery\u003c\/li\u003e\n  \u003cli\u003e60 grit, J-hardness (medium grade) balances material removal rate with surface finish\u003c\/li\u003e\n  \u003cli\u003ePorous structure improves chip clearance and reduces glazing during extended use\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum for safe operation on standard surface and cylindrical grinders\u003c\/li\u003e\n  \u003cli\u003eCompatible material range includes stainless steel, tool steels, carbon steels, aluminum, and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Power down and lock out the grinder before mounting or removing any wheel. Always inspect the wheel for cracks or chips before installation using the ring test, and never exceed the maximum RPM stamped on the wheel. Use proper blotter washers and flanges sized for the arbor hole to ensure safe, balanced operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A60-JVBE\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: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.73 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: 66252942835\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541870641458,"sku":"66252942835","price":141.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/008c2120c8446cd8cff72ccbe813e207.jpg?v=1785887246","url":"https:\/\/voomisupply.com\/products\/norton-66252942835-surface-grinding-wheel-60-grit-type-5","provider":"Voomi Supply","version":"1.0","type":"link"}
