Built with a ceramic abrasive grain and vitrified bond, it delivers consistent stock removal and long wheel life in demanding shop environments. The wheel measures 7 inches in diameter, 0.5 inches thick, with a 1-1\/4 inch arbor hole. Rated at a maximum of 3,600 RPM, it carries an I hardness code (medium grade) and 80 grit, making it a practical choice for moderate material removal on hardened work. Licensed machinists and grinding specialists install and dress this wheel type.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Documented material applications include 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The semi-friable ceramic grain continuously self-sharpens under load, maintaining cut rate without excessive heat buildup. The porous, vitrified bond structure allows coolant penetration and chip clearance, which is especially useful in tight-tolerance surface grinding passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain — semi-friable, self-sharpening under load\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure for coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003e80 grit, I hardness (medium grade) for moderate stock removal\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel, no recess, no taper\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed: 3,600 RPM\u003c\/li\u003e\n  \u003cli\u003eBlue wheel color consistent with 5SG series identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting a 7 inch diameter, 1\/2 inch wide Type 1 wheel with a 1-1\/4 inch arbor hole.

Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips using a ring test before mounting — do not install a damaged wheel. Operate within the stated maximum RPM; exceeding the rated speed is a safety hazard. Always dress the wheel before the first grinding pass on a new mount.\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\u003eArbor Hole 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\u003eMaximum RPM\u003c\/strong\u003e: 3,600\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 (Straight, No Recess)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 5SG80-IVSP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.125 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: 66252940527\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540316225842,"sku":"66252940527","price":211.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/396171d7014e52adc964bc9e024da2fd.jpg?v=1785852023","url":"https:\/\/voomisupply.com\/products\/norton-66252940527-surface-grinding-wheel-80-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
