It measures 12 inches in diameter, 1 inch thick, with a 5-inch arbor hole, and runs at a maximum of 2070 RPM. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond, carrying a medium grade designation and J hardness code. At 7.4 pounds, it is built for use on surface grinders, cylindrical grinders, and CNC cutting tool machines where consistent, controlled material removal is required.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a standard fit for surface grinder and cylindrical grinder setups in production machine shops, tool rooms, and maintenance facilities. The porous, vitrified structure promotes coolant flow and chip clearance, making it effective for medium-material-removal passes on a range of workpiece materials without glazing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive construction — suitable for ferrous and non-ferrous workpieces including stainless, carbon steels, and cast iron\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure for improved coolant flow and chip clearance during grinding\u003c\/li\u003e\n\u003cli\u003eJ hardness (medium grade) provides a balance between wheel life and cut rate on a wide range of materials\u003c\/li\u003e\n\u003cli\u003e60 grit size delivers medium stock removal with a consistent surface finish\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — standard Type 1 straight wheel profile for straightforward mounting\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed rated at 2070 RPM — do not exceed this rating\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.

Before mounting, ring-test the wheel for cracks and confirm the machine spindle speed does not exceed the wheel maximum of 2070 RPM. Power down and lock out the grinder before changing wheels. Always use the correct flanges and blotters for the arbor size and never force the wheel onto the spindle.\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: 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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\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: 2070\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\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32A60-JVBE\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: 7.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253262686\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542051356978,"sku":"66253262686","price":329.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f58a49887ead32693d5fbd65d54b9c4.jpg?v=1785890545","url":"https:\/\/voomisupply.com\/products\/norton-66253262686-surface-grinding-wheel-12in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
