Built on a vitrified bond with a ceramic abrasive grain, this wheel operates in the 3SG series, delivering consistent cutting action across wet and dry applications. At 8 inches in diameter, 1 inch thick, with a 1-1\/4 inch arbor hole and a one-side recess measuring 3-1\/4 inches in diameter by 1\/2 inch deep, it mounts directly to surface grinders and cylindrical grinders. The 46-grit, G-hardness (coarse, soft-rated) specification makes it well suited for aggressive stock removal while the semi-friable ceramic grain self-sharpens under load. Rated to 3600 RPM maximum, the wheel weighs 3.2 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders and cylindrical grinders in production and toolroom environments. Typical applications include grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The porous, vitrified structure promotes chip clearance and coolant penetration, making it effective for both wet and dry grinding cycles. It is commonly used by machinists, tool and die makers, and precision grinding technicians in industrial and job-shop settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain (3SG series) with semi-friable, self-sharpening properties for consistent cut rate\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure promotes chip clearance and coolant flow\u003c\/li\u003e\n\u003cli\u003e46 grit, G hardness (coarse, soft rating) optimized for aggressive stock removal on hard metals\u003c\/li\u003e\n\u003cli\u003eType 5 one-side recessed profile with 3-1\/4 inch recess diameter and 1\/2 inch recess depth\u003c\/li\u003e\n\u003cli\u003eRated for both wet and dry grinding operations up to 3600 RPM\u003c\/li\u003e\n\u003cli\u003ePurple wheel color for easy grade and series identification in the shop\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with surface grinders and cylindrical grinders accepting an 8 inch diameter, 1-1\/4 inch arbor hole Type 5 wheel.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and de-energize the grinder completely before changing wheels. Never exceed the 3600 RPM maximum operating speed 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: 8 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 Diameter\u003c\/strong\u003e: 3-1\/4 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\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\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 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3SG Type 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications Code\u003c\/strong\u003e: 3SGR46-GVP2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriable\u003c\/strong\u003e: Semi-Friable\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\u003eWeight\u003c\/strong\u003e: 3.2 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: 66253019361\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540160315698,"sku":"66253019361","price":254.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c2eebcf808b4a8b44289a0124c04fbe.jpg?v=1785847510","url":"https:\/\/voomisupply.com\/products\/norton-66253019361-type-5-surface-grinding-wheel-8in-46g","provider":"Voomi Supply","version":"1.0","type":"link"}
