It measures 8 inches in diameter and 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The abrasive matrix is aluminum oxide bonded with a vitrified bond, rated at 100 grit in a Fine grade with a Medium hardness rating (Hardness Code I). Specification designation is 32A100-IVBE. Rated to a maximum of 3600 RPM, this wheel is designed for use on surface grinders and cylindrical grinders in professional shop environments. Machinists, toolroom technicians, and grinding machine operators are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for both production and toolroom applications where a fine surface finish is required on a variety of workpiece materials. Typical use cases include surface grinding on CNC cutting tool machines, cylindrical grinders, and dedicated surface grinders. The aluminum oxide abrasive and vitrified bond make it effective on a broad range of metallic materials including stainless steel, carbon steel, tool steel, aluminum, and cast iron variants. It is non-tapered and features no recess, making it a straightforward straight-wheel configuration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for consistent cut on ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eVitrified bond for rigidity, porosity, and cool cutting action\u003c\/li\u003e\n\u003cli\u003e100 grit Fine grade delivers smooth surface finishes\u003c\/li\u003e\n\u003cli\u003eMedium hardness (Code I) balances wheel life and stock removal\u003c\/li\u003e\n\u003cli\u003ePorous structure supports chip clearance and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003eType 1 straight-wheel profile with no taper and no recess for straightforward mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with CNC cutting tool machines, cylindrical grinders, and surface grinders.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or damage before mounting, and perform a ring test per ANSI guidelines. Never exceed the 3600 RPM maximum speed rating marked on the wheel or packaging.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32A100-IVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.09 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: 66253043740\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541589459250,"sku":"66253043740","price":119.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30228ac549bf66b41bc6873b06a9edba.jpg?v=1785880063","url":"https:\/\/voomisupply.com\/products\/norton-66253043740-surface-grinding-wheel-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
