Built on a ceramic abrasive grain with a vitrified bond, this wheel measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole. The 5SG series ceramic grain is semi-friable, meaning it fractures to expose fresh cutting edges during use, reducing heat buildup and wheel loading. At 46 grit and K hardness (medium), it delivers coarse, fast cutting action suited to production surface grinding. Maximum operating speed is 2,485 RPM. Wheel color is blue. Weight is 6 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job-shop and production environments. It is rated for use on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The porous structure of the wheel promotes coolant flow and chip clearance, making it well suited to deep-cut or high-material-removal-rate operations where thermal damage to the workpiece is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic (5SG) abrasive grain — semi-friable for self-sharpening action and reduced heat generation\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and dimensional stability under load\u003c\/li\u003e\n\u003cli\u003e46 grit, K hardness (coarse, medium) for fast stock removal on hard alloys\u003c\/li\u003e\n\u003cli\u003ePorous structure enhances coolant penetration and swarf evacuation\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel geometry — no recess, no taper — for straightforward surface and cylindrical grinding setups\u003c\/li\u003e\n\u003cli\u003eRated for stainless, tool steels, titanium, super alloys, and iron castings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, ring-test the wheel and inspect for cracks or chips. Ensure the spindle speed of the machine does not exceed 2,485 RPM. Never overtighten flanges — use proper blotters and matched flange sets. Always dress the wheel before the first cut and allow the wheel to run at operating speed for at least one minute with the guard in place before presenting work.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 10 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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (flat, no recess, no taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic (5SG series)\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: 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: K (Medium)\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: 2,485\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 5SG46-KVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6 pounds\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: 66253160402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540152844594,"sku":"66253160402","price":413.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d3099668cc972667bc61607d0392ca8.jpg?v=1785847253","url":"https:\/\/voomisupply.com\/products\/norton-66253160402-surface-grinding-wheel-10in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
