Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and form retention on surface grinders, cylindrical grinders, and CNC cutting tool machines. At 120 grit with a J hardness code (medium hardness rating), it produces a fine finish suitable for finishing passes on tool steels, stainless steel, carbon steels, cast iron, and aluminum. The wheel measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and is rated to 3,600 RPM maximum. Weighing 1.59 pounds, it is a direct, single-unit replacement suitable for shop and field service use.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for both production and maintenance grinding applications in industrial and machine shop environments. It handles 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Licensed machinists, tool and die makers, and grinding technicians install this wheel on surface grinders and cylindrical grinders when a fine-grit, medium-hardness wheel is needed for controlled metal removal and surface finishing. The 32A Type 1 series specification (32A120-JVBE) identifies the exact abrasive, grit, hardness, bond, and structure for precise wheel selection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive provides durable, self-sharpening cutting action on a wide range of metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond delivers rigid, porous structure for free cutting and efficient coolant flow\u003c\/li\u003e\n  \u003cli\u003e120 grit fine grade produces smooth surface finishes on finishing passes\u003c\/li\u003e\n  \u003cli\u003eJ hardness (medium) balances wheel life against cut rate for controlled stock removal\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel geometry fits standard surface grinder and cylindrical grinder spindle configurations\u003c\/li\u003e\n  \u003cli\u003e3,600 RPM maximum operating speed — verify spindle RPM before mounting\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 the ring test before mounting, and ensure the spindle speed does not exceed the 3,600 RPM maximum marked on the wheel. Power down and lock out the machine before changing wheels. Use proper flanges and a blotter on each side of the wheel; never exceed the rated arbor hole size or overtighten the spindle nut.\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: 0.5 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\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: J\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\u003eSeries Specification\u003c\/strong\u003e: 32A120-JVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\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: 1.59 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: 66252941016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538253840690,"sku":"66252941016","price":97.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3088c7e63f76d706a23653a970364e27.jpg?v=1785820934","url":"https:\/\/voomisupply.com\/products\/norton-66252941016-surface-grinding-wheel-120-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
