It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel is constructed with aluminum oxide abrasive and a vitrified bond, delivering a medium-grade cut rated at J hardness. Maximum operating speed is 3600 RPM. The 32A Series designation indicates a well-established aluminum oxide grain structure suited for consistent material removal on hard and soft metals. Machinists and tool grinders install this wheel on surface grinders and cylindrical grinders.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding applications in production and maintenance shops handling a wide range of metals. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous, vitrified-bond construction allows coolant penetration and chip clearance during prolonged cuts, reducing heat buildup at the workpiece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled stock removal\u003c\/li\u003e\n\u003cli\u003e60 grit, J hardness (medium grade) for general-purpose surface grinding\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes coolant flow and reduces thermal loading\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess, compatible with standard surface grinder flanges\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003e32A Series specification (32A60-JVBE) for traceability and replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks using the ring test per ANSI B7.1 standards, and ensure the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Power down and lock out the grinder before changing wheels. Always use properly sized, clean flanges and blotters; never overtighten the arbor nut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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\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\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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 32A60-JVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.09 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: 66253043727\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542120431922,"sku":"66253043727","price":116.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/224db6d64a624a1520e2d8a8504ccce4.jpg?v=1785892678","url":"https:\/\/voomisupply.com\/products\/norton-66253043727-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
