Built on a vitrified bond with a ceramic abrasive grain, this wheel delivers consistent cut rate and form-holding under both wet and dry operating conditions. At 14 inches in diameter and 2 inches thick, it is sized for production surface grinders and cylindrical grinders where aggressive material removal is required. The 46 grit, G hardness (coarse grade, soft hardness rating) combination keeps the wheel free-cutting on hard, heat-sensitive workpiece materials. Maximum operating speed is 2320 RPM. Weight is 20.5 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for professional grinding operations in job shops, tool rooms, and manufacturing environments. The 3SG ceramic grain series is engineered for demanding material applications where conventional aluminum oxide wheels wear too quickly or generate excessive heat. It is appropriate for surface grinder and cylindrical grinder setups requiring a recessed Type 5 configuration. Wet or dry coolant operation is supported, giving operators flexibility based on machine setup and workpiece requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain (3SG series) for high cut rate on hard and difficult-to-grind materials\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigid structure and consistent form retention throughout wheel life\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade removes stock quickly while maintaining wheel integrity\u003c\/li\u003e\n\u003cli\u003eG hardness code (soft hardness rating) promotes self-dressing action to resist glazing\u003c\/li\u003e\n\u003cli\u003eOne-side recessed Type 5 profile with 8-inch recess diameter and 0.5-inch recess depth for clearance on recessed-hub flange setups\u003c\/li\u003e\n\u003cli\u003eRated for wet and dry operation at up to 2320 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on surface grinders and cylindrical grinders accepting a Type 5 wheel with a 5-inch arbor hole, 14-inch diameter, and 2-inch thickness.

Always perform a ring test before mounting and inspect the wheel for cracks or damage. Power down and lock out the grinder before changing wheels. Never exceed the 2320 RPM maximum operating speed stamped on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 2 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: G\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\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet and Dry\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-GVP2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 20.5 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: 66253319936\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540531577138,"sku":"66253319936","price":870.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a8798093ad99c6ced22885643fbe603.jpg?v=1785857633","url":"https:\/\/voomisupply.com\/products\/norton-66253319936-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
