Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent cutting action and long service life in demanding surface and cylindrical grinding applications. It measures 7 inches in diameter and 1 inch thick, with a 1-1\/4 inch arbor hole and a one-side recess of 0.5 inches deep and 2.75 inches in diameter. The 60-grit, K-hardness (medium grade) specification positions this wheel for efficient material removal while maintaining reasonable wheel life on difficult-to-grind alloys.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for surface grinders and cylindrical grinders running at a maximum of 3600 RPM. It is suited for production and maintenance grinding on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The semi-friable ceramic grain continuously fractures to expose fresh cutting edges, making it effective on heat-sensitive and work-hardening materials common in tool rooms and production grinding cells.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain with vitrified bond for consistent cut rate and wheel form retention\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure self-sharpens during use, reducing heat buildup on workpiece\u003c\/li\u003e- \u003cli\u003eType 5 recessed geometry — 0.5 inch recess depth, 2.75 inch recess diameter — clears flange and arbor interference\u003c\/li\u003e\n\u003cli\u003e60 grit, K hardness (medium grade) balances stock removal rate and wheel longevity\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eBlue wheel color consistent with Norton 5SG ceramic series identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders accepting a 7 inch diameter, 1-1\/4 inch arbor hole, Type 5 grinding wheel.

Before mounting, ring-test the wheel for cracks and verify the grinder spindle speed does not exceed the 3600 RPM maximum marked on the wheel. Use matched, relieved flanges of equal diameter and ensure blotter pads are seated properly between flanges and wheel faces. Never force a wheel onto a spindle or alter the arbor hole diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\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: 1.25 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 Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\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: K\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\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-KVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: 400 Series Stainless, Hard Carbon Steels, Tool Steels, Titanium, Super Alloys, Cast Iron, Ductile Iron, Gray Iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66252942432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540695712050,"sku":"66252942432","price":281.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56673dbeac790bfa2f1a840019c9641d.jpg?v=1785862193","url":"https:\/\/voomisupply.com\/products\/norton-66252942432-surface-grinding-wheel-60-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
