At 14 inches in diameter, 1 inch thick, and with a 5-inch arbor hole, it runs at a maximum of 2,320 RPM. The 46-grit, J-hardness (coarse grade) specification delivers aggressive stock removal while the vitrified bond maintains wheel integrity under heavy surface grinding loads. Weighing 11.43 pounds, this wheel is built for production-level use in machine shops and tool rooms. Licensed grinding technicians and machinists are the primary installers and operators.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications in both production and job-shop environments. The aluminum oxide abrasive makes it effective across a broad range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It carries the 32A Type 1 series designation and is non-porous with no recess and no taper, making it a straightforward mount for standard surface grinder spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e46-grit coarse aluminum oxide abrasive for high material removal rates\u003c\/li\u003e\n\u003cli\u003eJ hardness code with medium hardness rating for balanced wheel wear\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and consistent performance under load\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess and no taper for standard spindle mounting\u003c\/li\u003e\n\u003cli\u003eRated to 2,320 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eCompatible with a wide range of ferrous and non-ferrous materials including stainless, carbon steels, tool steels, and cast iron\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.

Always verify the machine spindle speed does not exceed the 2,320 RPM maximum rating marked on the wheel before installation. Inspect the wheel for cracks or chips before mounting and perform a ring test. Never exceed the rated speed and ensure the wheel guard is properly secured before operation.\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\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\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\u003eMaximum RPM\u003c\/strong\u003e: 2,320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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: Blue \/ Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 46J8V32A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.43 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: 66253246915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542103425330,"sku":"66253246915","price":162.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b60777f18b254c4679d9492256c7817.jpg?v=1785892136","url":"https:\/\/voomisupply.com\/products\/norton-66253246915-surface-grinding-wheel-46-grit-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
