It measures 14 inches in diameter, 1 inch thick, with a 5 inch arbor bore. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond system, producing a porous, open structure that clears swarf efficiently and reduces heat buildup at the workpiece. Hardness code J and medium grade classification indicate a wheel that releases dulled abrasive grains at a controlled rate, maintaining consistent cut on a range of ferrous alloys and cast metals. Rated at a maximum of 1800 RPM, it is sized for large-capacity surface grinders used in production and tool-room environments.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations in both production shops and tool-room settings. It performs on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The 32A series designation identifies the specific aluminum oxide grain formulation Norton uses for general-purpose ferrous grinding. At 11.75 pounds, the wheel requires proper flange and blotter mounting to distribute clamping load correctly across the hub area.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for versatile ferrous and non-ferrous stock removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure promotes swarf clearance and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eJ hardness code and medium grade for controlled grain release and consistent cut rate\u003c\/li\u003e\n\u003cli\u003e14 inch diameter x 1 inch thick x 5 inch bore — fits large production surface grinders\u003c\/li\u003e\n\u003cli\u003e1800 RPM maximum speed rating\u003c\/li\u003e\n\u003cli\u003eSeries 32A Type 1 straight wheel, no recess, non-tapered profile\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, perform a ring test to check for cracks. Power down and lock out the machine before changing wheels. Always use matched flanges and paper blotters of the correct diameter, and never exceed the maximum RPM marked on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore (Hole Size)\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\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 Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructure\u003c\/strong\u003e: Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\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 Designation\u003c\/strong\u003e: 32A80-JVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.75 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: 66253364038\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544431558962,"sku":"66253364038","price":550.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a2b7a77825a1f7e7421846ff5d5c116.jpg?v=1785926430","url":"https:\/\/voomisupply.com\/products\/norton-66253364038-surface-grinding-wheel-80-grit-14in","provider":"Voomi Supply","version":"1.0","type":"link"}
