Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent cut rates and extended wheel life compared to conventional aluminum oxide wheels. It measures 8 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole, and is rated to a maximum of 3,600 RPM. The medium-grade (K hardness) construction balances wheel longevity with free-cutting action, making it a reliable choice for production grinding environments. Licensed grinding machine operators and tool-and-die professionals are the primary installers of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding applications 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. The porous, semi-friable ceramic grain structure supports cool cutting on thermally sensitive alloys and hard ferrous materials where heat buildup and glazing are common failure points.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with vitrified bond for consistent stock removal and long wheel life\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile — no recess, non-tapered\u003c\/li\u003e\n  \u003cli\u003eMedium grade (K hardness) for balanced hardness and free-cutting performance\u003c\/li\u003e\n  \u003cli\u003ePorous, semi-friable grain structure reduces heat buildup on hard alloys and stainless\u003c\/li\u003e\n  \u003cli\u003e5SG series specification (5SG60-KVS) for traceability and OEM-spec replacement\u003c\/li\u003e\n  \u003cli\u003eRated to 3,600 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.

Always inspect the wheel for cracks or chips using the ring test before mounting, and ensure the machine spindle speed does not exceed the 3,600 RPM rated maximum. Power down and lock out the grinder before changing wheels. Never exceed the rated speed or use damaged blotters, flanges, or arbor hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\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\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 5SG60-KVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriable\u003c\/strong\u003e: Semi-Friable\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\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: 66253043351\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540601930034,"sku":"66253043351","price":185.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bd18e7ad68b9abee62e09c3a6eece66.jpg?v=1785859719","url":"https:\/\/voomisupply.com\/products\/norton-66253043351-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
