Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and thermal stability across long production runs. The wheel measures 14 inches in diameter, 1-1\/2 inches thick, with a 5-inch arbor hole. At 60 grit and I hardness (medium grade), it strikes the balance between aggressive material removal and surface finish quality. Rated to 1800 RPM, it is suited for shop-floor surface grinders and CNC tool grinding operations handled by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis wheel is a fit for production and job-shop environments running surface grinders, cylindrical grinders, and CNC cutting tool machines. The 32A specification designates NORTON's aluminum oxide grain blend, optimized for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous structure promotes chip clearance and coolant penetration, reducing heat buildup during extended cuts on thermally sensitive materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive grain for versatile ferrous and non-ferrous metal grinding\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and open structure for consistent cut rate\u003c\/li\u003e\n\u003cli\u003e60 grit, I hardness (medium grade) balances stock removal with surface finish\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure improves chip clearance and coolant flow\u003c\/li\u003e\n\u003cli\u003eType 1 straight profile with no recess, compatible with standard surface grinder spindle setups\u003c\/li\u003e\n\u003cli\u003eRated at 1800 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the 1800 RPM maximum rated speed. Use proper reducing bushings if required to match spindle arbor size, and ensure flanges, blotters, and guards are correctly fitted before powering the machine. Power down and lock out the grinder before mounting or removing the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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: 1800\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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32A60-IVBE\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 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: 66253364239\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538384748850,"sku":"66253364239","price":668.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a075a344868b242303cbdecfde10b3fc.jpg?v=1785824018","url":"https:\/\/voomisupply.com\/products\/norton-66253364239-surface-grinding-wheel-60-grit-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
