It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel uses a ceramic abrasive grain with a vitrified bond, delivering a semi-friable cutting action that continually exposes fresh grain for consistent stock removal. At 60 grit with a medium (I) hardness rating, it is suited for aggressive grinding passes where surface finish is secondary to cut rate. Rated to a maximum of 3600 RPM, it is appropriate for toolroom, production, and maintenance grinding applications.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and industrial environments. Typical applications include tool and die work, maintenance of cutting tools, and material conditioning on hard-to-grind workpieces. The 5SG Type 1 series targets demanding materials where conventional aluminum oxide wheels underperform, making it a common specification choice for aerospace, heavy fabrication, and toolroom shops running stainless, titanium, and super alloy components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with vitrified bond for cool, free-cutting action\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure self-sharpens during use to maintain cut rate\u003c\/li\u003e\n  \u003cli\u003e60 grit, medium (I) hardness suited for aggressive stock removal on hard metals\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel geometry with no recess for straightforward mounting\u003c\/li\u003e\n  \u003cli\u003eBlue wheel color aids in visual identification of ceramic grain series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use on surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the machine before mounting or removing any grinding wheel. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum RPM of 3600. Ensure flanges, blotters, and arbor hardware are clean and properly sized for the 1-1\/4 inch bore before tightening.\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: 60\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\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\u003eWheel Type\u003c\/strong\u003e: Type 1\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 5SG60-IVSP\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: 66252940525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542758555954,"sku":"66252940525","price":231.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a72ebdc7d4b6e4ad6227d97eb467bfdc.jpg?v=1785906484","url":"https:\/\/voomisupply.com\/products\/norton-66252940525-surface-grinding-wheel-7in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
