It is constructed with an aluminum oxide abrasive grain bonded in a vitrified bond matrix, delivering consistent stock removal and long wheel life. At 12 inches in diameter and 2 inches thick with a 5 inch arbor hole, this wheel is built for surface grinders and cylindrical grinders running at a maximum of 2070 RPM. The 46 grit coarse grade and H hardness rating make it well suited for aggressive cutting passes on a wide range of industrial materials. Weight is 13.85 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders and cylindrical grinders in production and maintenance grinding environments. It performs across a broad range of materials including 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The semi-friable aluminum oxide grain self-sharpens under load, making it effective for both roughing and controlled stock removal applications. The two-sided recess configuration allows for secure mounting on compatible wheel flanges.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 7 two-sided recessed wheel with 7.5 inch recess diameter and 0.5 inch recess depth for stable flange mounting\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade aluminum oxide abrasive for aggressive material removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity, porosity, and consistent cutting action throughout wheel life\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure promotes self-sharpening under grinding pressure\u003c\/li\u003e\n\u003cli\u003eRated to 2070 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eSpecification code 32A46-HVBEP identifies grain type, grit, hardness, bond, and structure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Before mounting, inspect the wheel for cracks or chips using the ring test. Always power down and lock out the grinder before changing wheels, and verify that the machine spindle speed does not exceed the 2070 RPM maximum rating stamped on this wheel. Never exceed the rated speed or use with incompatible flange hardware.\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: 2 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 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\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\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\u003eFriable\u003c\/strong\u003e: Semi-Friable\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\u003eSpecification\u003c\/strong\u003e: 32A46-HVBEP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.85 pounds\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: 66253263603\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544545788210,"sku":"66253263603","price":826.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4026ec3d9be0d8ee0701539e3039418.jpg?v=1785929415","url":"https:\/\/voomisupply.com\/products\/norton-66253263603-surface-grinding-wheel-46-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
