Built with a ceramic abrasive grain and a vitrified bond, it operates at a maximum of 3600 RPM and delivers consistent cut rates across wet and dry grinding applications. At 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, this wheel fits standard surface grinder spindles without modification. The G hardness code places it on the softer end of the vitrified bond scale, which promotes self-dressing action and helps prevent workpiece burning on harder materials.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding operations in production and tool-room environments. It 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 machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse 46-grit designation makes it a practical choice for roughing passes and high-stock-removal applications where surface finish is secondary to material removal rate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain for aggressive, consistent cutting on hard and abrasion-resistant materials\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and porosity for efficient chip clearance during grinding\u003c\/li\u003e\n\u003cli\u003e46 grit, G hardness (Coarse grade) promotes rapid stock removal with self-dressing behavior\u003c\/li\u003e\n\u003cli\u003eRated for wet and dry operation at up to 3600 RPM\u003c\/li\u003e\n\u003cli\u003eNo-recess, no-taper Type 1 flat wheel profile for straight surface and cylindrical grinding\u003c\/li\u003e\n\u003cli\u003ePurple wheel color for visual identification of the 3SG ceramic series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines requiring a 7 inch diameter, 1\/2 inch thick, Type 1 flat wheel with a 1-1\/4 inch arbor hole.

Always inspect the wheel for cracks or chips before mounting and perform a ring test to confirm structural integrity. Power down and lock out the machine before changing wheels. Never exceed the rated maximum RPM marked on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\/2 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\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: G\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\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\u003eSeries\u003c\/strong\u003e: 3SG Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 3SGR46-GVP2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: 66252916210\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542499098930,"sku":"66252916210","price":141.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f258130479444298c7c5b8bf24b29e9.jpg?v=1785902082","url":"https:\/\/voomisupply.com\/products\/norton-66252916210-surface-grinding-wheel-7in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
