Constructed with an aluminum oxide abrasive and a vitrified bond, this wheel measures 12 inches in diameter and 1.5 inches thick with a 5-inch arbor hole. It carries a 46-grit coarse grade and an H hardness code, suited for aggressive stock removal on a range of ferrous and non-ferrous metals. The wheel runs at a maximum of 2070 RPM and weighs 10.92 pounds. Licensed HVAC, metalworking, and machine shop professionals install this wheel on compatible grinding equipment as a direct production or maintenance tool.\u003c\/p\u003e\n\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is appropriate for both production grinding and tool-room applications where a coarse, free-cutting action is needed to remove material quickly. The one-side recessed Type 5 geometry accommodates equipment setups that require clearance at the wheel face. The 32A series specification designates this as a standard Norton aluminum oxide formulation suitable for demanding industrial grinding environments.\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\u003eVitrified bond provides rigidity and consistent cut rate throughout wheel life\u003c\/li\u003e\n  \u003cli\u003eType 5 one-side recessed profile with 7.5-inch recess diameter and 0.5-inch recess depth\u003c\/li\u003e\n  \u003cli\u003eRated for a maximum of 2070 RPM\u003c\/li\u003e\n  \u003cli\u003ePorous structure promotes coolant flow and chip clearance during grinding\u003c\/li\u003e\n  \u003cli\u003eCompatible with a broad range of ferrous and non-ferrous metals including stainless, tool steels, and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before installation and perform a ring test; never mount a damaged wheel. Use the correct flanges and blotters for the arbor size and never exceed the maximum RPM marked on the wheel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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: H\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\u003eMaximum RPM\u003c\/strong\u003e: 2070\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A46-HVBEP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.92 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: 66253263180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540706427186,"sku":"66253263180","price":469.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d21cf4001fb3534b38d881b46f875f22.jpg?v=1785862498","url":"https:\/\/voomisupply.com\/products\/norton-66253263180-surface-grinding-wheel-46-grit-type-5","provider":"Voomi Supply","version":"1.0","type":"link"}
