Built around a ceramic abrasive grain bonded in a vitrified matrix, this wheel delivers consistent cut rate and long service life on demanding materials including stainless steel, tool steels, titanium, super alloys, and cast iron. The wheel measures 7 inches in diameter and 1 inch thick with a 1-1\/4 inch arbor hole, rated to a maximum of 3600 RPM. At 60 grit with a J hardness code and medium grade classification, it is suited to moderate to heavy material removal where wheel friability and grain exposure are critical to performance.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in production and tool-room environments. Typical applications include surface grinding of 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, and both ductile and gray iron. The semi-friable ceramic grain continuously self-sharpens under load, making it well suited to high-pressure grinding passes where a conventional aluminum oxide wheel would glaze or burn the workpiece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with semi-friable structure for continuous self-sharpening during cut\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid grain retention and open wheel structure for coolant penetration\u003c\/li\u003e\n  \u003cli\u003e60 grit, J hardness, medium grade — balanced stock removal and surface finish for ferrous materials\u003c\/li\u003e\n  \u003cli\u003ePorous wheel construction promotes chip clearance and reduces heat buildup at the workpiece\u003c\/li\u003e\n  \u003cli\u003eBlue wheel color for visual identification of ceramic grain series\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess — compatible with standard surface and cylindrical grinder flanges\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 the wheel. Inspect the wheel for cracks or chips before each use — do not mount a damaged wheel. Verify the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 Straight\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: 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\u003eFriability\u003c\/strong\u003e: Semi-Friable\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\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: 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: 66252942429\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539205882162,"sku":"66252942429","price":229.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a042476e5727afc03dbd0c24f07301d2.jpg?v=1785836552","url":"https:\/\/voomisupply.com\/products\/norton-66252942429-surface-grinding-wheel-60-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
