Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent, controlled cutting action across a range of hard and soft materials. The wheel measures 14 inches in diameter and 2 inches thick with a 5-inch arbor hole, and carries a 60-grit, K-hardness (medium) rating. It is rated to a maximum of 1800 RPM. The vitrified bond structure provides rigidity and porosity, making it well suited for precision surface grinding where form retention and heat dissipation matter. Machinists and tool-and-die professionals are the primary users of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders and cylindrical grinders in both job shop and production environments. Verified material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The one-side recess measures 8 inches in diameter and 1 inch deep, reducing wheel weight and clearance interference on compatible flanged spindle setups. It suits applications that demand a stable, open-structure wheel capable of handling aggressive cuts without glazing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for rigidity and controlled stock removal\u003c\/li\u003e\n  \u003cli\u003e60 grit, K hardness (medium grade) suited for general-purpose and semi-finish grinding\u003c\/li\u003e\n  \u003cli\u003eType 5 recessed profile with 8-inch recess diameter and 1-inch recess depth for flange clearance\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes coolant flow and heat dissipation during extended grinding passes\u003c\/li\u003e\n  \u003cli\u003eCompatible with 400 Series stainless, carbon steels, tool steels, aluminum, and multiple cast iron grades\u003c\/li\u003e\n  \u003cli\u003e32A specification series — a recognized Norton aluminum oxide formulation for industrial grinding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always power down and lock out the grinder before mounting or removing the wheel. Perform a ring test before installation to check for cracks, and never exceed the 1800 RPM maximum speed rating marked on the wheel. Use matched, clean flanges of the correct diameter and install blotter gaskets as required by the machine manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\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: 1 inch\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: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\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\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 32A60-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 18.05 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: 66253364390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539400622386,"sku":"66253364390","price":904.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cd026c10eb091521d2fd630f3481581.jpg?v=1785839238","url":"https:\/\/voomisupply.com\/products\/norton-66253364390-surface-grinding-wheel-60-grit-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
