Built to the 48A46-HVP2 specification, it features an aluminum oxide abrasive bonded in a vitrified matrix, delivering consistent cut rate and controlled wear. The wheel measures 8 inches in diameter and 1 inch thick, with a 1-1\/4 inch arbor hole and a one-sided recess measuring 3.25 inches in diameter by 0.5 inches deep. Rated at a maximum of 3600 RPM, it carries an H hardness code and coarse 46-grit classification. The ruby-colored, porous wheel structure promotes coolant flow and chip clearance during wet or dry operation.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding operations on hard carbon steels, soft carbon steels, and tool steels. It is a standard choice for tool rooms, maintenance shops, and production grinding cells running pedestal or surface grinders. The vitrified bond provides dimensional stability across varying feed rates and depths of cut, making it appropriate for both roughing passes and light finishing work where coarse stock removal is the primary goal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut rate and long wheel life\u003c\/li\u003e\n\u003cli\u003eType 5 configuration with one-sided recess: 3.25 inches diameter, 0.5 inches deep\u003c\/li\u003e\n\u003cli\u003e46 grit, H hardness (coarse grade) for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM for use on surface grinders and cylindrical grinders\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure supports wet and dry operation\u003c\/li\u003e\n\u003cli\u003eSuitable for hard carbon steels, soft carbon steels, and tool steels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders accepting a Type 5 wheel with an 8 inch diameter, 1 inch face width, 1-1\/4 inch arbor hole, and a maximum spindle speed of 3600 RPM or lower.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation must be performed by a qualified operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Inspect the wheel for cracks or chips before mounting and perform a ring test per manufacturer guidelines. Ensure the machine spindle speed does not exceed the wheel's 3600 RPM maximum rating. Never force the wheel onto the arbor; use properly sized flanges and blotters, and allow the wheel to run at operating speed for at least one minute behind a guard before bringing it into contact with the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 3.25 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\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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\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\u003eSpecification\u003c\/strong\u003e: 48A46-HVP2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 48A Type 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet and Dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hard Carbon Steels, Soft Carbon Steels, Tool Steels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.2 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: 66253019366\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538877710642,"sku":"66253019366","price":160.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fefeb58be4bb02a29f8ad23d20ad95fe.jpg?v=1785828704","url":"https:\/\/voomisupply.com\/products\/norton-66253019366-surface-grinding-wheel-46-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
