Built with a ceramic abrasive grain and vitrified bond, this wheel delivers consistent cut rates and thermal resistance across extended production runs. At 8 inches in diameter, 1\/2 inch thick, and with a 1-1\/4 inch arbor hole, it installs on standard surface grinder spindles. The 46-grit, J-hardness specification places it in the coarse-cut, medium-hardness category — well suited for stock removal applications where surface finish is secondary to material takedown rate. Rated at 3,600 RPM maximum, it falls within the operating envelope of most production surface grinders.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs on a broad range of demanding materials including 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The semi-friable ceramic grain self-sharpens as it breaks down, reducing the need for frequent dressing in production environments. It is a practical choice for tool rooms, job shops, and production grinding cells working with high-alloy and high-hardness workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with vitrified bond for aggressive stock removal and thermal stability\u003c\/li\u003e\n  \u003cli\u003e46 grit, coarse grade for high material removal rates on hard metals\u003c\/li\u003e\n  \u003cli\u003eJ hardness code, medium hardness rating — resists glazing while maintaining form\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure continuously exposes fresh cutting edges during use\u003c\/li\u003e\n  \u003cli\u003ePorous wheel construction promotes coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003e3,600 RPM maximum speed rating for use on standard production surface grinders\u003c\/li\u003e\n  \u003cli\u003eSeries 5SG Type 1 specification (5SG46-JVS) for straightforward procurement and replacement\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 power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Follow ANSI B7.1 safety requirements for wheel mounting, guarding, and speed verification before returning the machine to service.\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: 0.5 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\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\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\u003eWheel Type\u003c\/strong\u003e: Type 1\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\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 5SG46-JVS\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  \u003cli\u003e\n\u003cstrong\u003eCompatible Equipment\u003c\/strong\u003e: CNC Cutting Tool Machine, Cylindrical Grinder, Surface Grinder\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: 66253044090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538897076530,"sku":"66253044090","price":220.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb01642e96d5139f9a76ba43d3f22e31.jpg?v=1785829002","url":"https:\/\/voomisupply.com\/products\/norton-66253044090-surface-grinding-wheel-46-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
