Built with aluminum oxide abrasive and a vitrified bond, this wheel operates at a maximum of 3600 RPM and carries a coarse 46-grit rating with an H hardness code. The 8-inch diameter and 1\/2-inch thickness suit standard surface and cylindrical grinder spindle configurations. At 1.8 pounds, the wheel is compatible with wet grinding operations and is color-coded ruby, consistent with the 48A series designation. Licensed grinding machine operators and tool-and-die technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for wet surface grinding operations on hard carbon steels, soft carbon steels, and tool steels. It fits surface grinders, cylindrical grinders, and CNC cutting tool machines equipped for Type 1 straight-wheel mounting. The 1-1\/4-inch arbor hole accommodates standard spindle sizes common in production and toolroom environments. The porous, vitrified bond structure promotes coolant flow and heat dissipation during extended wet grinding passes, making it well-suited for close-tolerance surface finishing work in both job shop and production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent stock removal on ferrous metals\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade rated for aggressive material removal in wet grinding applications\u003c\/li\u003e\n\u003cli\u003eH hardness code with porous wheel structure supports coolant penetration and thermal management\u003c\/li\u003e\n\u003cli\u003eType 1 straight-wheel profile with no recess and no taper for direct arbor mounting\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 3600 RPM — do not exceed this rating\u003c\/li\u003e\n\u003cli\u003eSpecification designation 48A46-HVP2 for cross-reference and replacement verification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Inspect the wheel for cracks or chips before each use — never mount a damaged wheel. Power down and lockout\/tagout the grinding machine completely before changing wheels. Use properly rated flanges and never exceed the 3600 RPM maximum speed rating stamped on the wheel or stated by the manufacturer.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\u003eWheel Type\u003c\/strong\u003e: Type 1\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\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\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 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253019350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538972246322,"sku":"66253019350","price":89.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce5a652589057dd3aea8852c21911e7d.jpg?v=1785831414","url":"https:\/\/voomisupply.com\/products\/norton-66253019350-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
