Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent cut rates and long service life under the thermal and mechanical demands of surface and cylindrical grinding operations. It measures 14 inches in diameter, 1.5 inches thick, with a 5-inch center hole and a one-side recess measuring 8 inches in diameter and 0.5 inches deep. The 46-grit coarse grade and H hardness rating make it well suited for rapid stock removal where surface finish is secondary to throughput. Maximum operating speed is 2320 RPM.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders and cylindrical grinders in industrial and tool-room environments. It is rated for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The semi-friable ceramic grain continuously self-sharpens as it fractures, reducing glazing and heat buildup during extended grinding passes. The 3SG Type 5 series designation identifies it within the NORTON structured ceramic line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with semi-friable structure for continuous self-sharpening action\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and open porosity for coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003e46-grit coarse grade optimized for high stock removal on hard and exotic metals\u003c\/li\u003e\n  \u003cli\u003eH hardness code (soft wheel hardness rating) reduces heat and wheel loading on difficult materials\u003c\/li\u003e\n  \u003cli\u003eType 5 one-side recessed profile fits standard surface and cylindrical grinder spindle configurations\u003c\/li\u003e\n  \u003cli\u003ePurple wheel color for quick visual identification of the 3SG ceramic series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation using the ring test, and never exceed the rated maximum speed of 2320 RPM. Use appropriate flanges, blotters, and a properly fitted arbor for the 5-inch center hole before torquing to the grinder 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: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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\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: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2320\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3SG Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 3SGR46-HVP2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.5 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: 66253319954\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538731204914,"sku":"66253319954","price":687.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/836c9569cd17f26603fd54772f2d8159.jpg?v=1785825855","url":"https:\/\/voomisupply.com\/products\/norton-66253319954-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
