Measuring 14 inches in diameter and 2 inches thick with a 5-inch arbor hole, this wheel carries a 46-grit coarse grade with an I hardness code, rated to a maximum of 2320 RPM. The vitrified bond provides rigidity and free-cutting action across a broad range of base materials. At 11.43 pounds, it is built for production surface grinding and is installed by machinists and tool-room technicians on industrial surface grinders and CNC cutting tool machines.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its coarse 46-grit cut makes it most effective in stock-removal passes rather than finish-grinding operations. Typical applications include surface grinders and cylindrical grinders in machine shops, toolrooms, and production grinding environments where consistent cut rate and wheel life are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e46-grit coarse grade aluminum oxide abrasive for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eI hardness code with vitrified bond for rigidity and consistent cut rate\u003c\/li\u003e\n  \u003cli\u003e14-inch diameter x 2-inch thick Type 1 flat wheel configuration with no recess\u003c\/li\u003e\n  \u003cli\u003e5-inch arbor hole fits standard surface grinder spindles\u003c\/li\u003e\n  \u003cli\u003eRated to 2320 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eNon-porous construction; blue and gray wheel color for visual identification\u003c\/li\u003e\n  \u003cli\u003eSeries 32A Type 1 specification: 46I8V32A\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 perform a ring test before mounting to check for cracks, and never exceed the maximum operating RPM of 2320. Confirm the machine spindle speed does not exceed the wheel rating before startup. Stand clear of the wheel plane during the initial startup run-out period.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 2 inches\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: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2320\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 Code\u003c\/strong\u003e: 46I8V32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\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 and Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.43 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: 66253246809\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540618838322,"sku":"66253246809","price":282.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d432a359570cd6993a5327feb6f1afb8.jpg?v=1785860239","url":"https:\/\/voomisupply.com\/products\/norton-66253246809-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
