Measuring 7 inches in diameter and 1 inch thick with a 1-1\/4 inch arbor hole, this wheel uses aluminum oxide abrasive bonded in a vitrified matrix. The 46 grit, J hardness (coarse grade, semi-friable) construction delivers aggressive material removal while maintaining consistent wheel breakdown on softer workpiece materials. A single-side recess of 1\/2 inch deep and 3 inches in diameter reduces wheel weight and improves coolant access at the grinding face. Rated to a maximum of 3600 RPM.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for use on cylindrical grinders and surface grinders in tool rooms, maintenance shops, and production environments. The Gemini Precision Vitrified series is designed for applications requiring controlled wheel wear and repeatable surface finish on soft carbon steels and tool steels. The blue and gray wheel color is consistent with NORTON Gemini vitrified bonds. This is a single-piece package appropriate for bench or floor grinding machine setups where a Type 5 recessed wheel geometry is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 5 single-side recessed profile with 3 inch recess diameter and 1\/2 inch recess depth\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive, semi-friable, for use on soft carbon steels and tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigid, precise cutting action with consistent breakdown rate\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade with J hardness for aggressive material removal\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eGemini Precision Vitrified series construction for repeatable grinding performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with cylindrical grinders and surface grinders where a Type 5 recessed wheel with a 1-1\/4 inch arbor hole is required.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the 3600 RPM maximum speed rating marked on the wheel.\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 3 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\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: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\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\u003eWeight\u003c\/strong\u003e: 2.86 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Gemini Precision Vitrified Grinding Wheels\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: 66253246835\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542886351154,"sku":"66253246835","price":85.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40862f1d61c1d3a72f99a35ffbd1896b.jpg?v=1785909967","url":"https:\/\/voomisupply.com\/products\/norton-66253246835-surface-grinding-wheel-7in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
