Built with ceramic abrasive grain in a vitrified bond, this wheel delivers consistent cut rates and long service life under high-load grinding conditions. It measures 7 inches in diameter, 3\/4 inches thick, with a 1-1\/4 inch arbor hole. At 46 grit and I hardness (coarse grade, medium hardness rating), it is well matched for aggressive stock removal rather than fine finishing. Maximum operating speed is 3600 RPM. Installation and operation are performed by machining professionals and tool-room technicians on appropriate guarded grinding equipment.\u003c\/p\u003e\n\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Compatible grinding equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The semi-friable ceramic grain self-sharpens during use, reducing glazing and maintaining cut efficiency across extended runs on difficult workpiece materials. It is suitable for both production and toolroom environments where material hardness demands a wheel that holds its edge without frequent dressing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain — semi-friable for consistent self-sharpening and reduced glazing\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and open structure for free cutting action\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade suited for high stock-removal passes\u003c\/li\u003e\n  \u003cli\u003eI hardness code (medium hardness rating) balances wheel life against cut rate\u003c\/li\u003e\n  \u003cli\u003ePorous structure promotes coolant flow and chip clearance during wet or dry grinding\u003c\/li\u003e\n  \u003cli\u003eRated for stainless, tool steels, titanium, super alloys, cast iron, and ductile iron\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 ring-test the wheel for cracks before mounting and confirm the machine spindle speed does not exceed the 3600 RPM rating marked on the wheel. The machine guard must be in place and properly adjusted before powering the grinder. Never force a wheel onto a spindle or use an adapter that alters the specified arbor bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\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: 0.75 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: I\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: 3600\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\u003eSpecifications\u003c\/strong\u003e: 5SG46-IVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.38 pounds\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: 66252942304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543540695346,"sku":"66252942304","price":232.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c84e1aa3bda1f5d70c1d73e78a670b90.jpg?v=1785920140","url":"https:\/\/voomisupply.com\/products\/norton-66252942304-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
