Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and good form-holding under load. It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The 46-grit, coarse-grade construction removes material aggressively, making it well suited for rough grinding passes where surface finish is secondary to stock removal rate. Rated to a maximum of 3,105 RPM, it is installed and operated by machinists and grinding technicians on surface and cylindrical grinding equipment.\u003c\/p\u003e\u003cp\u003eThis wheel is used in both production and toolroom environments where consistent abrasive performance is required across a range of materials. Typical applications include surface grinding on hard and soft carbon steels, 400-series stainless steel, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is used with surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse grit makes it a go-to choice for initial material removal before finishing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive provides reliable cutting action on ferrous metals and cast iron\u003c\/li\u003e\n\u003cli\u003eVitrified bond offers rigidity and consistent wheel breakdown during grinding\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade suited for aggressive stock removal passes\u003c\/li\u003e\n\u003cli\u003eG hardness code indicates a soft-to-medium wheel hardness rating for controlled wear\u003c\/li\u003e\n\u003cli\u003ePorous structure promotes coolant flow and chip clearance during grinding\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel geometry with no recess — straightforward mounting on standard flanges\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or chips before mounting and perform a ring test on vitrified wheels. Power down and lock out the grinder before changing wheels. Never exceed the maximum operating speed of 3,105 RPM; verify the spindle speed of your machine before mounting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 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: 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: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\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\u003eSpecifications\u003c\/strong\u003e: 32A46-GVBEP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.09 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: 66253043882\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540781957426,"sku":"66253043882","price":116.42,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffa66a7f47a39680b34b26d522aae610.jpg?v=1785863897","url":"https:\/\/voomisupply.com\/products\/norton-66253043882-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
