Built with aluminum oxide abrasive and a vitrified bond, it measures 12 inches in diameter and 1.5 inches thick with a 5-inch arbor hole. The H hardness code and 46 coarse grit make it well suited for heavy-duty surface and cylindrical grinding applications where fast cutting action is the priority. Rated at a maximum of 2070 RPM, this wheel carries a full part number specification of 46H8V32A and belongs to the Norton 32A Type 5 series. Licensed grinding professionals and tool-room machinists are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders and cylindrical grinders in industrial and trade shop environments. Material compatibility covers a broad range of metals, including 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The one-side recessed geometry with a 7.5-inch recess diameter and 0.5-inch recess depth provides clearance for flange mounting on standard wheel spindles. Both production grinding and precision tool-room work fall within its intended application range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut and long wheel life\u003c\/li\u003e\n  \u003cli\u003e46 coarse grit, H hardness rating for fast material removal on hard and soft metals\u003c\/li\u003e\n  \u003cli\u003eType 5 one-side recessed profile: 7.5-inch recess diameter, 0.5-inch recess depth\u003c\/li\u003e\n  \u003cli\u003eRated to 2070 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with multiple metal types including stainless, carbon steels, tool steels, and cast irons\u003c\/li\u003e\n  \u003cli\u003eFull specification code 46H8V32A for direct cross-reference and replacement sourcing\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 de-energize the grinder before mounting or removing wheels. Inspect the wheel for cracks or damage using the ring test before installation, and never exceed the maximum RPM rating stamped on the wheel or packaging. Flanges must be clean, flat, and the correct diameter for this wheel size before tightening.\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\u003eArbor Hole Size\u003c\/strong\u003e: 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\u003eRecess Type\u003c\/strong\u003e: One-Side\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 Color\u003c\/strong\u003e: Blue \/ Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 46H8V32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 5\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\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: 66253246856\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538791334194,"sku":"66253246856","price":134.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a63b0ca869df879150f70d2ed2513dd7_da1e3110-62e2-48ec-ae7b-0a0378d721e7.jpg?v=1785826712","url":"https:\/\/voomisupply.com\/products\/norton-66253246856-surface-grinding-wheel-12in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
