It measures 7 inches in diameter, 1\/2 inch thick, and carries a 1-1\/4 inch arbor hole for direct mounting on standard surface and cylindrical grinders. The aluminum oxide abrasive is bonded with a vitrified process and rated at a coarse 46 grit with a J hardness code, placing it in the medium-hardness range. This combination delivers aggressive stock removal while maintaining consistent wheel integrity throughout the grind cycle. Rated to 3600 RPM maximum, this wheel is part of the Gemini Precision Vitrified Grinding Wheels series.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding applications in tool rooms, production shops, and maintenance environments. It is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse 46-grit specification makes it a practical choice for initial stock removal passes on soft carbon steels and tool steels where a fine finish is not the priority. Machinists and tool-and-die technicians are the primary installers and operators of this type of wheel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e46 grit aluminum oxide abrasive for coarse, aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond construction provides rigidity and consistent cut performance\u003c\/li\u003e\n\u003cli\u003eJ hardness code, medium-hardness rating, supports controlled wear in steel grinding applications\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess, compatible with standard surface grinder chucks and flanges\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.

Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting and perform a ring test. Never exceed the 3600 RPM maximum speed rating printed 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: 7 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\u003eWheel Type\u003c\/strong\u003e: Type 1\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: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue and Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Gemini Precision Vitrified Grinding Wheels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 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: 66253246802\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542722216242,"sku":"66253246802","price":75.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0176fc7cc87ce0676cc01489762887c7.jpg?v=1785905370","url":"https:\/\/voomisupply.com\/products\/norton-66253246802-surface-grinding-wheel-7in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
