Built with a ceramic abrasive grain and a vitrified bond, this wheel operates at a maximum of 3600 RPM and delivers consistent cut rate across a wide range of demanding applications. At 7 inches in diameter and 1\/4 inch thick with a 1-1\/4 inch arbor hole, the wheel fits standard surface grinder spindles used in production and tool-room environments. The J hardness code and medium grade classification indicate a moderately hard wheel that holds its form while still releasing dull grain effectively.\u003c\/p\u003e\n\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous, semi-friable ceramic structure suits operations where heat buildup is a concern and where consistent surface finish on difficult alloys is required. The 5SG Type 1 series designation identifies it within the Norton Quantum ceramic line used across precision grinding operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with vitrified bond for high material removal rates and thermal resistance\u003c\/li\u003e\n  \u003cli\u003eJ hardness code and medium grade provide a balance of form retention and self-dressing action\u003c\/li\u003e\n  \u003cli\u003ePorous, semi-friable structure reduces heat transfer to the workpiece during grinding\u003c\/li\u003e\n  \u003cli\u003eRated for stainless steels, tool steels, titanium, super alloys, and various cast irons\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess, suitable for straight surface and cylindrical grinding\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 3600 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B11.9 standards. Never exceed the maximum operating speed of 3600 RPM stamped on the wheel or listed by the machine manufacturer.\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\/4 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\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\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\u003ePorous\u003c\/strong\u003e: Yes\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\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-JVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252939463\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538320654642,"sku":"66252939463","price":129.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad5b058883350bcb2351f71906ec4551.jpg?v=1785822921","url":"https:\/\/voomisupply.com\/products\/norton-66252939463-surface-grinding-wheel-7in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
