Built with white aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, controlled cutting action across soft carbon steels, tool steels, and super alloys. It measures 8 inches in diameter, 1\/4 inches thick, and carries a 1-1\/4 inch arbor hole. The 80 grit, medium-grade specification and semi-friable abrasive structure make it well-suited for work that requires a balance between material removal rate and surface finish quality. Rated to a maximum of 3600 RPM, it is installed and operated by machinists and tool-and-die professionals on production grinding equipment.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. Typical applications include finish grinding of tool steel components, super alloy workpieces, and soft carbon steel parts where controlled surface finish is required. The 38A series designation identifies this as a standard aluminum oxide formulation within the NORTON 38A Type 1 line, recognized across machine shops for general-purpose ferrous grinding work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive for consistent, cool cutting on ferrous metals\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigid wheel structure and predictable wear characteristics\u003c\/li\u003e\n\u003cli\u003e80 grit, medium grade balances stock removal with surface finish quality\u003c\/li\u003e\n\u003cli\u003eSemi-friable abrasive continuously self-sharpens to reduce loading on softer steels and super alloys\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess and no taper for straightforward mounting\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or chips before mounting and perform a ring test to confirm structural integrity. Power down and lock out the grinder before mounting or removing any wheel. Never exceed the 3600 RPM maximum speed rating stamped on the wheel or stated on the blotter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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: 80\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\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\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: 0.25 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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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\u003ePorous\u003c\/strong\u003e: Non-Porous\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\u003eSpecifications\u003c\/strong\u003e: 38A80-IVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.04 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: 66253043437\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539557777714,"sku":"66253043437","price":68.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c639d5e36beee233599e186845a4c177.jpg?v=1785843036","url":"https:\/\/voomisupply.com\/products\/norton-66253043437-surface-grinding-wheel-80-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
