Built with aluminum oxide abrasive and a vitrified bond, this wheel measures 7 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole. The 120-grit, fine-grade specification and K hardness rating make it well suited for controlled material removal where surface finish is a priority. Rated to 3600 RPM, it carries the 32A120-KVBE specification designation. At under one pound, it fits standard surface grinder spindles without excessive mass. Licensed machinists, tool-and-die makers, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. It performs reliably on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The fine 120-grit aluminum oxide abrasive is particularly effective for finishing passes and tight-tolerance work where aggressive stock removal is not required. It is a porous, non-tapered, no-recess wheel with a gray body color, consistent with the 32A Type 1 series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-grit fine-grade aluminum oxide abrasive for precision surface finishing\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction provides rigidity and consistent cut rate\u003c\/li\u003e\n  \u003cli\u003eK hardness rating with medium wheel hardness — suited for harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum speed rating for surface and cylindrical grinder applications\u003c\/li\u003e\n  \u003cli\u003ePorous, non-tapered, no-recess Type 1 wheel geometry\u003c\/li\u003e\n  \u003cli\u003eCompatible with multiple workpiece materials including stainless steel, tool steel, aluminum, and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Operate only at or below the 3600 RPM maximum speed rating; exceeding this limit is a serious safety hazard.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\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\u003eSpecification\u003c\/strong\u003e: 32A120-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\u003eWeight\u003c\/strong\u003e: 0.79 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: 66252939682\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544539595058,"sku":"66252939682","price":96.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c0749f961642423f81f0a3cc9f6da69.jpg?v=1785929232","url":"https:\/\/voomisupply.com\/products\/norton-66252939682-surface-grinding-wheel-7in-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
