Measuring 7 inches in diameter and 1\/2 inch thick with a 1-1\/4 inch arbor hole, this wheel uses a ceramic abrasive grain in a vitrified bond matrix. Rated to 3600 RPM, the J hardness code and medium grade classification give it the right balance of cut rate and wheel life for surface grinding applications. The semi-friable ceramic grain continuously micro-fractures during use, exposing fresh cutting edges without requiring frequent dressing cycles.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Typical users include tool-and-die shops, machine shops, and industrial maintenance professionals who require consistent stock removal and surface finish control on demanding materials. The porous structure of the wheel promotes coolant flow and chip clearance during wet or dry grinding operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with semi-friable character for continuous self-sharpening action\u003c\/li\u003e\n  \u003cli\u003eVitrified bond for rigidity and dimensional stability under load\u003c\/li\u003e\n  \u003cli\u003eJ hardness (medium grade) balances wheel life with cut aggressiveness\u003c\/li\u003e\n  \u003cli\u003e80 grit for moderate stock removal with acceptable surface finish\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure aids coolant penetration and swarf evacuation\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile fits standard surface and cylindrical grinder flanges\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 thick, Type 1 wheel with a 1-1\/4 inch arbor hole.

Always de-energize and lock out the machine before mounting or removing a grinding wheel. Verify that the machine's rated spindle speed meets or stays below the 3600 RPM maximum marked on the wheel — never exceed the wheel's maximum RPM rating. Inspect the wheel for cracks or chips before mounting and perform a ring test; discard any wheel that does not emit a clear tone.\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\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight, No Recess)\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\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\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: 3600\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\u003eSpecification Code\u003c\/strong\u003e: 5SG80-JVS\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: 66252940201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540147077426,"sku":"66252940201","price":189.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ccc628a34257a261c28a0bdc0afd761.jpg?v=1785847079","url":"https:\/\/voomisupply.com\/products\/norton-66252940201-surface-grinding-wheel-80-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
