Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent cutting action and thermal resistance across extended grinding cycles. At 14 inches in diameter and 1.5 inches thick, with a 5-inch arbor hole, it mounts to standard surface and cylindrical grinders. The 46 grit, coarse grade removes stock aggressively, while the I hardness (medium) rating and semi-friable grain structure allow the wheel to self-dress under load, maintaining sharp cutting edges. Maximum operating speed is 1800 RPM. Weight is 15.89 pounds.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for precision surface grinding and cylindrical grinding applications in production and toolroom environments. It performs on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The one-side recessed profile (Type 5) provides clearance for the grinding spindle hub, making it a common choice for surface grinder setups where flange clearance is a factor. It is appropriate for both industrial production shops and maintenance operations where aggressive stock removal on hard-to-grind materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with semi-friable structure for self-dressing behavior and consistent cut rate\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity, porosity, and heat resistance during heavy surface grinding\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade for aggressive stock removal on hard ferrous and exotic alloy workpieces\u003c\/li\u003e\n  \u003cli\u003eType 5 one-side recessed profile (8-inch recess diameter, 0.5-inch recess depth) for spindle hub clearance\u003c\/li\u003e\n  \u003cli\u003eI hardness medium rating balances wheel wear against material hardness across a broad workpiece range\u003c\/li\u003e\n  \u003cli\u003eRated to 1800 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Before mounting, inspect the wheel for cracks or damage using the ring test per ANSI B7.1 standards, and ensure the machine is fully de-energized and locked out. Never exceed the marked maximum RPM of 1800. Use proper flanges and a blotter on each side of the wheel, and allow the wheel to run at operating speed in a guarded area for at least one minute before presenting work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1.5 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\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: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1800\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\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: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 5SG46-IVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15.89 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66253364102\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540519452978,"sku":"66253364102","price":952.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b681d53ad8d81040fa28fe11be15afe.jpg?v=1785857289","url":"https:\/\/voomisupply.com\/products\/norton-66253364102-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
