Built on a ceramic abrasive grain with a vitrified bond, this wheel measures 14 inches in diameter, 1 inch thick, and carries a 5-inch arbor hole. The 46-grit coarse grade and J hardness code position it for aggressive material removal while the semi-friable ceramic grain self-sharpens under load, reducing glazing and heat buildup at the contact zone. Rated to 1800 RPM, it is suited for use on surface grinders and CNC cutting tool machines. The wheel weighs 11 pounds.\u003c\/p\u003e\n\u003cp\u003eThis wheel targets industrial and tool-room grinding tasks on materials that demand a tough, free-cutting abrasive. Typical applications include surface grinding of 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is well suited for production shops running surface grinders and cylindrical grinders, as well as CNC cutting tool machines requiring consistent stock removal on difficult-to-grind workpiece materials. The porous structure promotes coolant flow and chip clearance during extended grinding passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain for aggressive, cool-cutting performance on hard and exotic metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and dimensional stability at operating speed\u003c\/li\u003e\n  \u003cli\u003e46-grit coarse grade with J hardness code for high stock removal\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure self-sharpens under load to reduce wheel glazing\u003c\/li\u003e\n  \u003cli\u003ePorous wheel construction improves coolant delivery and swarf clearance\u003c\/li\u003e\n  \u003cli\u003eType 1 flat profile with no recess, compatible with standard surface grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before each installation using a ring test, and never exceed the maximum rated RPM of 1800. A proper wheel blotter and flanges of matching diameter must be used to ensure safe, concentric seating on the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 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\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1800\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\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\u003eSpecification Code\u003c\/strong\u003e: 5SG46-JVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11 pounds\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: 66253363971\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540570308914,"sku":"66253363971","price":831.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d75d5b5585333365a3197b39d2d72bc.jpg?v=1785858712","url":"https:\/\/voomisupply.com\/products\/norton-66253363971-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
