Built around an aluminum oxide abrasive grain bonded with a vitrified bond, this wheel delivers consistent cut rates and free-cutting action across production grinding applications. It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and carries a 46 grit coarse grade with an I hardness rating. Maximum operating speed is rated at 3,105 RPM. At 3.73 pounds, the wheel suits manual and automated surface grinding setups where repeatable flatness is required.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse 46 grit removes material efficiently on softer workpiece materials, including soft carbon steels and tool steels, where aggressive stock removal takes priority over fine finish work. The porous structure promotes chip clearance and reduces heat buildup during extended grinding passes. Licensed trades machinists, toolroom operators, and production grinders are the primary installers and users of this wheel type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain — suited for soft carbon steels and tool steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction for rigidity and consistent form holding\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes chip clearance and cooler grinding\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eI hardness (medium) balances wheel life and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile — no recess, no taper\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

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 rated maximum RPM of 3,105 printed on the wheel blotter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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: I\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\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\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\u003eWheel Color\u003c\/strong\u003e: Blue \/ Gray\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\u003eSpecification\u003c\/strong\u003e: GEMINI 46-I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.73 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66253246843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544569774386,"sku":"66253246843","price":78.54,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25ab19cf5bc2c2c64e124f44c50572d7.jpg?v=1785930233","url":"https:\/\/voomisupply.com\/products\/norton-66253246843-surface-grinding-wheel-46-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
