Built on a vitrified bond with a silicon carbide abrasive, this wheel delivers consistent cut rates and controlled surface finishes. It measures 7 inches in diameter, 1\/2 inch thick, and carries a 1-1\/4 inch arbor hole. The 80 grit, Medium (I) hardness rating positions it squarely in the finishing-to-medium-stock-removal range. Rated to 3,600 RPM maximum, it is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Machinists, tool-and-die makers, and maintenance grinders are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for grinding 300 series stainless steel, titanium, aluminum, brass, bronze, and copper, as well as gray iron, masonry, and natural stone. It performs best on dedicated surface grinders in both job-shop and production environments. The non-porous, vitrified bond structure resists loading on non-ferrous metals and holds form well during interrupted cuts. Typical applications include flat surface finishing, tool reconditioning, and light face grinding where a consistent, medium grit finish is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide abrasive — effective on non-ferrous metals, cast iron, masonry, and natural stone\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction provides rigid support and consistent material removal rates\u003c\/li\u003e\n  \u003cli\u003eMedium (I) hardness, 80 grit for balanced stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eNon-porous wheel body resists clogging when grinding soft or ductile materials\u003c\/li\u003e\n  \u003cli\u003e3,600 RPM maximum operating speed rated for surface and cylindrical grinder use\u003c\/li\u003e\n  \u003cli\u003eType 1 flat-wheel profile with no recess — direct-mount to standard arbor flanges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with CNC cutting tool machines, cylindrical grinders, and surface grinders accepting a 1-1\/4 inch arbor and operating at or below 3,600 RPM.

Before mounting, perform a ring test to check for cracks, and verify the machine spindle speed does not exceed the 3,600 RPM maximum rating marked on the wheel. Power down and lock out the grinder before changing wheels. Never operate a grinding wheel that has been dropped or shows visible damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Flat, No Recess)\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: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\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\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Green\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 39C80-IVMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.352 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: 66252941617\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542705865010,"sku":"66252941617","price":155.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13a7a3becb66564dd55b2b3f2eab1122.jpg?v=1785904893","url":"https:\/\/voomisupply.com\/products\/norton-66252941617-surface-grinding-wheel-80-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
