Built on an aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent cut rates and predictable wear across extended grinding cycles. It measures 12 inches in diameter, 1 inch thick, with a 5-inch arbor hole, and carries a 60-grit, medium-grade (Hardness Code I) specification rated to a maximum of 2070 RPM. The vitrified bond structure is porous, promoting coolant flow and chip clearance during heavy-duty surface grinding operations. Licensed machinists, tool-and-die makers, and industrial maintenance technicians are the primary installers and operators of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in production and job-shop environments. Its aluminum oxide abrasive makes it effective across a broad range of material applications including 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is suitable for both roughing passes requiring aggressive material removal and finishing passes where surface finish consistency matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for broad material compatibility including stainless, carbon steels, and cast iron\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure promotes coolant penetration and swarf clearance\u003c\/li\u003e\n  \u003cli\u003e60-grit medium grade (Hardness Code I) balances stock removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel geometry with no recess and no taper for straightforward mounting\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 2070 RPM — verify machine spindle speed before mounting\u003c\/li\u003e\n  \u003cli\u003eSeries 32A specification (32A60-IVBE) for consistent abrasive performance across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or chips using a ring test before mounting, and never exceed the stated maximum RPM of 2070. Power down and lock out the grinder before changing wheels. Use properly sized flanges and a compressible blotter between the flange and wheel face as required by applicable safety standards.\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 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 32A60-IVBE\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\u003eMaximum RPM\u003c\/strong\u003e: 2070\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\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\u003eWeight\u003c\/strong\u003e: 7.973 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: 66253262582\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541834760498,"sku":"66253262582","price":287.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7cad998bea06639f51af89755b6f920.jpg?v=1785886312","url":"https:\/\/voomisupply.com\/products\/norton-66253262582-surface-grinding-wheel-60-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
