Built with a ceramic abrasive grain and vitrified bond, it delivers consistent stock removal and maintains wheel form longer than conventional aluminum oxide wheels. At 80 grit with an I hardness code (medium grade), it is suited for aggressive grinding passes where surface finish requirements are moderate. Rated to 3600 RPM, this wheel is designed for use on surface grinders and CNC cutting tool machines. The porous, semi-friable structure promotes cooler cutting and reduces glazing during extended runs.\u003c\/p\u003e\n\u003cp\u003eThis wheel is sized at 7 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole, making it a standard fit for bench-type and reciprocating surface grinders. Its material application range covers 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is typically installed and dressed by machinists or tool grinders in job shops, aerospace facilities, and production grinding environments. The blue ceramic grain construction is identified under the Norton 5SG Type 1 series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain for high-performance grinding on hard and heat-sensitive alloys\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure reduces heat buildup and minimizes glazing\u003c\/li\u003e\n  \u003cli\u003e80 grit, medium grade (hardness code I) for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM for surface grinder and CNC cutting tool machine use\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain continuously self-sharpens during the cut\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess for straightforward mounting\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.

Before mounting, ring-test the wheel for cracks and verify that the machine spindle speed does not exceed the 3600 RPM rating marked on the wheel. Power down and lock out the grinder before removing the existing wheel and installing the new one. Always use proper flange hardware and blotters; never force the wheel onto the spindle arbor.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 5SG80-IVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: 66252940200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543510876466,"sku":"66252940200","price":176.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbc13dedf7dfa5cf17f595a665a9e151.jpg?v=1785919730","url":"https:\/\/voomisupply.com\/products\/norton-66252940200-surface-grinding-wheel-80-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
