Built with aluminum oxide abrasive grain in a vitrified bond matrix, this wheel delivers consistent cutting action and thermal stability under both wet and dry grinding conditions. It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and is rated to a maximum of 3600 RPM. The 60 grit, medium grade, H hardness specification positions it for general-purpose surface grinding where controlled material removal and a moderate surface finish are required.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. The 38A series aluminum oxide grain is semi-friable, meaning it fractures to expose fresh cutting edges during use, making it well-matched to soft carbon steels and super alloys where heat buildup must be managed. It supports both wet coolant and dry grinding setups, giving technicians flexibility across different machine configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60 grit, medium grade aluminum oxide abrasive for general-purpose surface grinding\u003c\/li\u003e\n  \u003cli\u003eH hardness (soft hardness rating) vitrified bond for consistent wheel breakdown and fresh grain exposure\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure minimizes heat buildup on workpiece surface\u003c\/li\u003e\n  \u003cli\u003eCompatible with wet and dry grinding operations\u003c\/li\u003e\n  \u003cli\u003eNo recess, no taper — standard Type 1 flat wheel profile\u003c\/li\u003e\n  \u003cli\u003eWhite wheel color for easy visual identification of aluminum oxide composition\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 perform a ring test before mounting and verify the machine spindle speed does not exceed the 3600 RPM maximum wheel rating. Mount with appropriate flanges and blotters; never exceed rated speed or force the wheel onto the arbor. Dress the wheel with a suitable dressing tool before first use to true the face and open the abrasive surface.\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: 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\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: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Soft\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\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet and Dry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: 66252916225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544553914674,"sku":"66252916225","price":78.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2d635f1903a0acf10efdb5f45368b65.jpg?v=1785929718","url":"https:\/\/voomisupply.com\/products\/norton-66252916225-surface-grinding-wheel-60-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
