Built with an aluminum oxide abrasive grain and a vitrified bond, it delivers consistent cut rates and thermal stability throughout the grinding cycle. The wheel measures 7 inches in diameter by 1 inch thick with a 1-1\/4 inch arbor hole and a one-side recess of 1\/2 inch depth at 3 inches in diameter. Rated at a maximum of 3600 RPM and carrying a coarse 46-grit, G-hardness designation, this wheel suits high-removal-rate applications where surface finish is secondary to throughput. Weighing 2.93 pounds, it is sized for surface grinders and cylindrical grinders in production and maintenance shop environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders and cylindrical grinders in both production and maintenance settings. Material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse grit and soft hardness rating allow the wheel to cut freely on harder alloys while minimizing heat buildup and loading on gummy materials such as aluminum and cast iron. It is appropriate for both manual surface grinders and automatic reciprocating table machines in industrial or toolroom environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 5 recessed profile with a 1\/2 inch deep, 3 inch diameter one-side recess for clearance on recessed-hub grinder flanges\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive grain in the 32A series — suited for ferrous metals and select non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity, porosity, and consistent breakdown for controlled stock removal\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade removes material quickly where surface finish is not the primary requirement\u003c\/li\u003e\n  \u003cli\u003eG hardness (soft) grade allows the wheel to shed dull grains freely, reducing heat and glazing risk\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum speed rating; confirm operating RPM does not exceed this value before mounting\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 mounting or removing a wheel. Inspect the wheel visually and perform a ring test before mounting; never use a wheel that shows cracks, chips, or damage. Use proper flanges, blotters, and a correctly sized arbor bushing to ensure concentric seating — never force a wheel onto a spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 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: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 32A46-GVBEP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.93 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: 66252942825\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540375077170,"sku":"66252942825","price":158.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29001d9ca3b4f17ea7cfab58efa99653.jpg?v=1785853730","url":"https:\/\/voomisupply.com\/products\/norton-66252942825-type-5-surface-grinding-wheel-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
