It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel uses an aluminum oxide abrasive bonded in a vitrified matrix, producing a coarse 46-grit cut at a J-hardness rating. Rated to 3600 RPM, it is sized for surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous structure promotes chip clearance and helps prevent loading when working on soft carbon steels and tool steels.\u003c\/p\u003e\u003cp\u003eThis wheel is part of the Gemini Precision Vitrified Grinding Wheels series and is well suited to production and maintenance grinding operations in machine shops, tool rooms, and industrial facilities. Typical applications include flat surface finishing, tool reconditioning, and precision material removal on soft carbon steels and tool steels. The coarse 46-grit specification makes it appropriate for aggressive stock removal rather than fine finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled cut\u003c\/li\u003e\n\u003cli\u003eCoarse 46-grit, J-hardness (medium) rating for aggressive stock removal on soft metals\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes chip clearance and reduces loading\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM for safe operation on compatible grinding equipment\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess — straightforward mounting and dressing\u003c\/li\u003e\n\u003cli\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines\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 — never install a damaged wheel. Verify the machine spindle speed does not exceed the 3600 RPM rating marked on the wheel before operation.\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\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 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: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\/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\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels\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\u003eWeight\u003c\/strong\u003e: 3.73 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: 66253246845\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540692599090,"sku":"66253246845","price":78.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fec070b0842a37154ad40f722098dc0.jpg?v=1785862113","url":"https:\/\/voomisupply.com\/products\/norton-66253246845-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
