Built from aluminum oxide abrasive with a vitrified bond, this wheel measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. It carries a 60-grit, medium-grade designation and a hardness code of I, making it well-suited for moderate material removal on soft carbon steels, tool steels, and super alloys. The semi-friable grain structure allows controlled breakdown during use, helping maintain a consistent cut and surface finish. Rated at 3600 RPM maximum, it is a standard choice for surface and cylindrical grinding setups.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used in both shop and production environments where flat-surface grinding accuracy is required. Typical applications include surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs best on soft carbon steels, tool steels, and super alloys where a medium-grade wheel provides the right balance of cut rate and finish quality. The white aluminum oxide construction and non-porous, vitrified bond deliver consistent performance across repeated dressing cycles, making it a reliable option for tool rooms and production grinding operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with semi-friable grain for controlled wear and consistent cut\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction for rigidity and reliable performance through repeated dress cycles\u003c\/li\u003e\n  \u003cli\u003e60 grit, medium grade, hardness code I for balanced stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eNon-porous, Type 1 flat wheel profile with no recess and no taper\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines\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.

Before mounting, inspect the wheel for cracks or chips using the ring test per ANSI B11.9 guidelines. Power down and lock out the grinder before changing wheels. Never exceed the 3600 RPM maximum speed rating marked on the wheel.\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\u003eHole 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: I\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 Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 38A60-IVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriable\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\u003eWeight\u003c\/strong\u003e: 2.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253043757\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544536219954,"sku":"66253043757","price":99.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e70df4b4fbb9266fd9bca20f131464e.jpg?v=1785929105","url":"https:\/\/voomisupply.com\/products\/norton-66253043757-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
