Built to the 32A series specification, this wheel measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole. The 46-grit coarse grade and J hardness rating make it well-suited for aggressive material removal while maintaining consistent wheel geometry. Rated at a maximum of 2705 RPM, this non-porous, vitrified-bond wheel delivers reliable, repeatable performance across production grinding environments. Installation is handled by qualified grinding machine operators following standard wheel-mounting procedures.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is appropriate for use in industrial and production shops working with a range of metals. Documented material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse grit and medium hardness rating suit high-stock-removal passes rather than fine finishing work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess — direct mounting to standard surface and cylindrical grinders\u003c\/li\u003e\n\u003cli\u003e46-grit coarse aluminum oxide abrasive for aggressive material removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond construction provides rigidity and consistent cut rate\u003c\/li\u003e\n\u003cli\u003eJ hardness code and medium hardness rating balance wheel life against cut aggressiveness\u003c\/li\u003e\n\u003cli\u003eNon-porous structure resists loading when grinding steels and cast irons\u003c\/li\u003e\n\u003cli\u003eSpecification codes 46K8V32A and 46J8V32A confirm full Norton 32A series compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting a 12-inch diameter, 3-inch hole Type 1 wheel.

Always inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI guidelines. Power down and lock out the grinder before installing or changing wheels. Never exceed the marked maximum RPM of 2705 under any operating condition.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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\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\u003eMaximum RPM\u003c\/strong\u003e: 2705\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\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 46K8V32A, 46J8V32A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue, Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253246894\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542755246386,"sku":"66253246894","price":97.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3281b804fdc5fb40b6931ad3a51584c6.jpg?v=1785906365","url":"https:\/\/voomisupply.com\/products\/norton-66253246894-surface-grinding-wheel-12in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
