It measures 8 inches in diameter by 0.5 inches thick with a 1.25-inch arbor hole. The wheel uses aluminum oxide abrasive bonded in a vitrified matrix, delivering consistent cut rate and free cutting action across a range of steel workpiece materials. Rated at a maximum of 3600 RPM, it carries a medium grade with an I hardness code, making it well suited for controlled surface finishing and flat grinding applications where wheel wear and workpiece geometry need to be balanced.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in production and toolroom environments. Its aluminum oxide abrasive is effective on hard carbon steels, soft carbon steels, and tool steels. The 32A Series Type 1 flat-profile design fits standard horizontal-spindle surface grinding setups common in machine shops and tool and die operations. The porous, vitrified bond structure promotes coolant flow and chip clearance during wet or dry grinding operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 flat wheel profile — no recess, no taper — fits standard arbor mounting\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut rate and easy dressing\u003c\/li\u003e\n  \u003cli\u003e60 grit, medium grade, I hardness code — suited for stock removal on steel workpieces\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003e32A Series specification (32AA60-IVTR) for material application on carbon and tool steels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or chips using the ring test before mounting, and verify that the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Power down and lock out the grinder before mounting or removing the wheel. Use proper flanges and a blotter on each side of the wheel as required by ANSI standards, and run the wheel at operating speed under guard 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: 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\u003eArbor Hole 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\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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 32AA60-IVTR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hard Carbon Steels, Soft Carbon Steels, Tool Steels\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: 66253038894\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542225223986,"sku":"66253038894","price":141.11,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/917a5a320e1643145bfde37d4edb0994.jpg?v=1785895630","url":"https:\/\/voomisupply.com\/products\/norton-66253038894-surface-grinding-wheel-8-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
