Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent cut rates and cooler grinding temperatures compared to conventional aluminum oxide wheels. It measures 7 inches in diameter and 1 inch thick, with a 1-1\/4 inch arbor hole and a single-side recess of 1\/2 inch deep by 2-3\/4 inches in diameter. Rated at 3600 RPM maximum, it carries an H hardness code and a coarse 46 grit designation, making it well-suited for high-material-removal applications where surface finish is secondary to throughput. Wheel weight is 2.75 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders and cylindrical grinders in professional shop environments. It is rated for wet grinding operation, which supports heat management when working through hard or heat-sensitive materials. Documented material applications include 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The 3SG Type 5 series designation identifies it as part of Norton's ceramic grain line, intended for production grinding where wheel life and cut consistency matter. It is packaged and sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain (semi-friable) for self-sharpening action and extended wheel life\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and porosity for efficient coolant flow during wet grinding\u003c\/li\u003e\n\u003cli\u003eType 5 single-side recessed profile reduces wheel weight and improves clearance on recessed-spindle machines\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade optimized for rapid stock removal on ferrous and high-temperature alloys\u003c\/li\u003e\n\u003cli\u003eH hardness code (soft grade) allows the wheel to release dull grains readily, reducing heat buildup\u003c\/li\u003e\n\u003cli\u003eWet operation rated for compatibility with water-soluble and oil-based grinding fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders and cylindrical grinders.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test on vitrified wheels. Never exceed the rated maximum RPM of 3600; verify spindle speed against the wheel rating before startup. Use appropriate flanges and blotters as specified by the machine manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 5 (Single-Side Recessed)\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 (Soft)\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Wet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\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\u003eSpecifications\u003c\/strong\u003e: 3SGR46-HVP2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.75 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: 66252916228\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541320728882,"sku":"66252916228","price":188.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f5b8eadea1f019af02c207460dd19df.jpg?v=1785872369","url":"https:\/\/voomisupply.com\/products\/norton-66252916228-type-5-surface-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
