Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent stock removal and a fine surface finish at up to 3600 RPM. It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The K hardness rating and semi-friable grain structure make it well suited for controlled grinding where heat and wheel breakdown need to be managed carefully. It is installed and operated by machinists, tool and die makers, and grinding specialists in production and job shop environments.\u003c\/p\u003e\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 designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous, vitrified bond structure promotes coolant flow and chip clearance during wet or dry grinding operations. The blue wheel color is consistent with NORTON 5SG series ceramic grain wheels, which are specified for demanding material applications where conventional abrasives lose form or cut rate too quickly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain with vitrified bond for long wheel life and consistent cut rate\u003c\/li\u003e\n\u003cli\u003e100 grit, fine grade finish suitable for semi-finish and finish grinding passes\u003c\/li\u003e\n\u003cli\u003eK hardness (medium) balances wheel wear and workpiece surface integrity\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain continuously self-sharpens under load, reducing glazing\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure supports coolant penetration and swarf evacuation\u003c\/li\u003e\n\u003cli\u003eRated for 400 series stainless, tool steels, titanium, super alloys, and cast and ductile iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks or chips using a ring test. Confirm the spindle RPM does not exceed the 3600 RPM maximum rated speed of this wheel. Always install proper wheel flanges and guards before returning the machine to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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\u003eGrit\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\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: 5SG100-KVS\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: 66252940205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541042954546,"sku":"66252940205","price":168.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f083d743f9dae37e8581800687fb4290.jpg?v=1785867731","url":"https:\/\/voomisupply.com\/products\/norton-66252940205-surface-grinding-wheel-7in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
