It measures 7 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole. The wheel uses a ceramic abrasive grain bonded with a vitrified bond, which resists heat buildup and maintains a consistent cut rate throughout the wheel's life. Rated at 3600 RPM maximum, it is suited for both wet and dry operation. The coarse 46 grit and H hardness code make it effective for aggressive material removal on surface grinders and cylindrical grinders.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on CNC cutting tool machines, cylindrical grinders, and surface grinders in industrial and job-shop environments. It performs on a wide range of difficult materials including 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The 3SG Type 1 series is a standard choice for machine shops and tool rooms requiring reliable, repeatable cuts on high-hardness workpieces. It supports both wet coolant and dry grinding setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain with vitrified bond for consistent cut rate and heat resistance\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade for aggressive material removal\u003c\/li\u003e\n\u003cli\u003eH hardness code, soft hardness rating for efficient self-dressing action\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum speed rating\u003c\/li\u003e\n\u003cli\u003eWet and dry operation compatible\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure for balanced sharpness and durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting a Type 1 wheel with a 1.25-inch arbor hole.

Before mounting, inspect the wheel for cracks or chips using the ring test. Power down and lock out the grinder before changing wheels. Never exceed the maximum rated RPM of 3600; always confirm the machine spindle speed before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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\u003eSeries\u003c\/strong\u003e: 3SG Type 1 (3SGR46-HVP2)\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: 0.5 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: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet and Dry\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: Purple\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\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252916211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543537287474,"sku":"66252916211","price":122.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90e10acb7ae1cc4c587e91b6993fc929.jpg?v=1785920067","url":"https:\/\/voomisupply.com\/products\/norton-66252916211-surface-grinding-wheel-46-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
