Built with a ceramic abrasive grain and vitrified bond, this wheel carries a 60-grit, medium-grade (J hardness) specification suited for controlled, cool cutting action. It measures 7 inches in diameter, 1\/2 inch thick, and accepts a 1-1\/4 inch arbor. The porous, semi-friable ceramic grain structure continuously self-sharpens during use, maintaining cut rate and surface finish across extended grinding cycles. This wheel is installed and operated by skilled machinists, tool-and-die technicians, and precision grinding professionals.\u003c\/p\u003e\n\u003cp\u003eThe 66252940197 is designed for surface grinding operations on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. Its blue vitrified wheel construction and porous structure make it well matched to applications where heat buildup must be minimized and consistent stock removal is required across production or maintenance grinding tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain for aggressive cutting with reduced heat generation\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure promotes coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003e60 grit, J hardness (medium grade) balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile fits standard surface and cylindrical grinder spindles\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain continuously fractures to expose fresh cutting edges\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks or chips using the ring test as specified by ANSI B11.9 grinding safety standards. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 3600 RPM maximum rated speed of this wheel. Never exceed the rated RPM, overtighten flange hardware, or use damaged blotters or flanges.\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\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\u003eGrade (Hardness Code)\u003c\/strong\u003e: J (Medium)\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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size (Arbor)\u003c\/strong\u003e: 1.25 inches\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\u003eManufacturer Specification\u003c\/strong\u003e: 5SG60-JVS\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: 66252940197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539307495730,"sku":"66252940197","price":188.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d10456ff5420aec4b1d80bb03db69ca.jpg?v=1785838121","url":"https:\/\/voomisupply.com\/products\/norton-66252940197-surface-grinding-wheel-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
