It measures 12 inches in diameter, 3\/4 inches thick, with a 3-inch arbor hole. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond, rated at a medium grade with a K hardness code. The 60-grit specification targets general-purpose material removal where a balance of cut rate and surface finish is required. Maximum operating speed is 2,070 RPM. This wheel is used by machinists and grinding technicians in production and tool-room environments.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding applications on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its porous vitrified structure promotes coolant flow and chip clearance, making it effective on both wet and dry grinding setups. Compatible machines include CNC cutting tool machines, cylindrical grinders, and surface grinders. The 32A series designation indicates Norton's standard aluminum oxide grain formulation, widely recognized in precision grinding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess and no taper for straightforward mounting\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive grain suited for ferrous metals and cast iron\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure for improved coolant flow and chip clearance\u003c\/li\u003e\n\u003cli\u003e60 grit, K hardness (medium grade) for balanced stock removal and surface quality\u003c\/li\u003e\n\u003cli\u003e2,070 RPM maximum operating speed rated for production grinders\u003c\/li\u003e\n\u003cli\u003e32A60-KVBE specification for direct cross-reference in grinding wheel selection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNC cutting tool machines, cylindrical grinders, and surface grinders.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum RPM stamped on the wheel or listed in the product specifications. Use appropriate flanges and blotters as specified by the machine manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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: K\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\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\u003eMaximum RPM\u003c\/strong\u003e: 2,070\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A60-KVBE\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: 6.78 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: 66253262273\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542125478194,"sku":"66253262273","price":277.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f37ab93a3c168e0ed6afa54634887c18.jpg?v=1785892838","url":"https:\/\/voomisupply.com\/products\/norton-66253262273-surface-grinding-wheel-60-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
