Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent cut rate and long wheel life under high-cycle production conditions. The wheel measures 7 inches in diameter, 1 inch thick, with a 1-1\/4 inch arbor hole. Hardness is rated K (Medium) with a semi-friable grain structure that self-sharpens under load, reducing glazing on difficult-to-grind materials. Rated to 3600 RPM maximum, it is suited for surface grinders, cylindrical grinders, and CNC cutting tool machines.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is well suited to production and toolroom environments where consistent surface finish and dimensional accuracy on hard or abrasion-resistant workpieces are required. The vitrified bond structure provides rigidity and coolant permeability, making it a practical choice for wet or dry precision surface grinding operations across both job shops and high-volume manufacturing settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain for high material removal rates on hard alloys and super alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond for rigidity, dimensional stability, and coolant compatibility\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure self-sharpens to reduce glazing and maintain cut rate\u003c\/li\u003e\n\u003cli\u003eK (Medium) hardness rating balances wheel life with free-cutting action\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes coolant flow and reduces heat buildup at the workpiece\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — standard Type 1 flat wheel geometry for broad machine compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use on surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or chips using the ring test before mounting — never mount a damaged wheel. Power down and lock out the grinder before changing wheels, confirm the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel, and use the correct flanges and blotter paper as required by the machine manufacturer. Stand clear of the wheel plane during the initial run-up period.\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: 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\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\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\u003eTapered\u003c\/strong\u003e: No\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\u003eSpecification\u003c\/strong\u003e: 5SG60-KVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252942430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539518783794,"sku":"66252942430","price":261.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96818f3534519687e78fa4474fa1b345.jpg?v=1785842401","url":"https:\/\/voomisupply.com\/products\/norton-66252942430-surface-grinding-wheel-7in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
