It measures 7 inches in diameter, 1-1\/2 inches thick, and carries a 1-1\/4 inch arbor hole with a single-side recess of 3\/4 inch depth and 2-3\/4 inch recess diameter. The abrasive material is aluminum oxide — designated 32A — bonded with a vitrified matrix, which delivers consistent cut rate and thermal stability under grinding loads. Hardness code I places it in the medium grade range, appropriate for broad-contact surface work. The wheel is rated to a maximum of 3600 RPM and weighs 4.47 pounds. Licensed machinists, tool-and-die workers, and industrial maintenance mechanics are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on surface grinders and cylindrical grinders in both shop and industrial maintenance settings. The aluminum oxide abrasive and vitrified bond combination make it effective across a range of materials. Rated material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a practical choice for production grinding environments where consistent wheel life and predictable breakdown are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 5 recessed wheel profile with a 3\/4 inch recess depth and 2-3\/4 inch recess diameter for clearance in surface grinder applications\u003c\/li\u003e\n  \u003cli\u003e32A aluminum oxide abrasive grain — friable-resistant construction for sustained cut rate\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides thermal stability and open structure for efficient swarf evacuation\u003c\/li\u003e\n  \u003cli\u003eMedium hardness (Grade I) balances wheel life with consistent material removal\u003c\/li\u003e\n  \u003cli\u003ePorous structure aids coolant penetration and reduces heat buildup at the workpiece\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 3600 RPM — compatible with standard surface and cylindrical grinder spindle speeds\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 ring-test the wheel for cracks before mounting and use the correct flanges and blotters for the arbor size. Never exceed the maximum operating speed of 3600 RPM. Guard the wheel properly and allow it to run at operating speed for at least one minute before engaging the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2-3\/4 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: Aluminum Oxide (32A)\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: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStructure\u003c\/strong\u003e: Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A60-IVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.47 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: 66252942844\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539416940850,"sku":"66252942844","price":217.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8a89ad9b62da597a2a1f499a19a6473.jpg?v=1785839750","url":"https:\/\/voomisupply.com\/products\/norton-66252942844-surface-grinding-wheel-60-grit-type-5","provider":"Voomi Supply","version":"1.0","type":"link"}
