Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent cut rates and extended wheel life under both wet and dry operating conditions. It measures 8 inches in diameter, 1\/2 inch thick, and accepts a 1-1\/4 inch arbor bore. The coarse 46-grit, G-hardness rating suits aggressive material removal applications. Maximum operating speed is 3600 RPM. Licensed HVAC techs, machinists, and tool-and-die tradespeople handling precision surface grinding work rely on wheels in this specification class.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications in both shop and production environments. Compatible material applications include 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The porous, semi-friable ceramic structure supports free cutting action, making this wheel well suited for hard, heat-sensitive workpiece materials where thermal damage is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain for consistent cut rate and extended service life on hard alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and porosity for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eCoarse 46-grit, G-hardness for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eRated for wet and dry operation up to 3600 RPM\u003c\/li\u003e\n\u003cli\u003ePorous, semi-friable structure reduces heat buildup on sensitive materials\u003c\/li\u003e\n\u003cli\u003eNo-recess, straight Type 1 wheel profile for standard surface and cylindrical grinder spindles\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 inspect the wheel for cracks or chips before mounting and perform a ring test on vitrified wheels. Power down and lock out the grinder before changing wheels, confirm the machine spindle speed does not exceed the 3600 RPM maximum marked on the wheel, and use the correct arbor flanges and blotters for a Type 1 straight wheel. Never exceed the rated maximum RPM under any circumstances.\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: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\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\u003eSeries\u003c\/strong\u003e: 3SG Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 3SGR46-GVP2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet and Dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriable\u003c\/strong\u003e: Semi-Friable\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\u003eWheel Color\u003c\/strong\u003e: Purple\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 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: 66253019345\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544519409970,"sku":"66253019345","price":147.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc8c4f10a18ebe0e1213e37a9e966bf8.jpg?v=1785928699","url":"https:\/\/voomisupply.com\/products\/norton-66253019345-surface-grinding-wheel-46-grit-8in","provider":"Voomi Supply","version":"1.0","type":"link"}
