It measures 7 inches in diameter and 1 inch thick, with a 1-1\/4 inch arbor hole and a 2-3\/4 inch recess diameter at 1\/2 inch depth on one side. The wheel uses Norton's ceramic abrasive grain in a vitrified bond, rated at J hardness (medium grade) and 60 grit. The ceramic grain is semi-friable, meaning it fractures to expose fresh cutting edges during use, reducing heat buildup and extending wheel life compared to conventional aluminum oxide.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders and cylindrical grinders in production and maintenance shops. Material applications include 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The Type 5 recessed profile provides clearance for certain wheel flanges and workholding setups common in precision surface grinding operations. It is sized for shops running 7-inch capacity machines and suits both toolroom and production grinding environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic semi-friable abrasive grain continuously fractures for consistent cut rate and reduced glazing\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and porosity for free chip clearance during grinding\u003c\/li\u003e\n  \u003cli\u003eType 5 one-side recess (2-3\/4 inch diameter, 1\/2 inch deep) clears flanges and adapters\u003c\/li\u003e\n  \u003cli\u003e60 grit medium grade removes material efficiently while maintaining controllable surface finish\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with a broad range of hard ferrous and exotic alloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders and cylindrical grinders.

Always perform a ring test before mounting and never exceed the 3600 RPM maximum speed marked on the wheel. Power down and lock out the grinder before changing wheels. Use proper flanges and blotters as specified for the machine and wheel diameter.\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\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\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\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 5SG60-JVS\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: 66252942431\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540445004082,"sku":"66252942431","price":249.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8b381f8c50f5c2961fa0ce1926220d0.jpg?v=1785855383","url":"https:\/\/voomisupply.com\/products\/norton-66252942431-surface-grinding-wheel-7in-60-grit-type-5","provider":"Voomi Supply","version":"1.0","type":"link"}
