Built on an aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent cut rates and long service life across a range of metalworking applications. The wheel measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. Running at a maximum rated speed of 3600 RPM, it carries a K hardness code and a medium grade classification. Licensed machinists and tool room technicians are the primary installers and users of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for grinding soft carbon steels, tool steels, and super alloys in both production and toolroom environments. It performs on surface grinders where flat, accurate finishes are required, as well as on cylindrical grinders for OD grinding operations. The 80 grit designation makes it appropriate for moderate material removal where surface finish quality still matters. The vitrified bond structure self-dresses consistently, which helps maintain cut efficiency throughout the wheel life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive rated for soft carbon steels, tool steels, and super alloys\u003c\/li\u003e\n  \u003cli\u003eVitrified bond for consistent self-dressing and stable cutting action\u003c\/li\u003e\n  \u003cli\u003e80 grit, medium grade for balanced stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eK hardness code provides firm wheel structure suited to moderate grinding pressures\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-tapered, no-recess Type 1 straight wheel profile\u003c\/li\u003e\n  \u003cli\u003eSemi-friable abrasive grain for controlled breakdown under load\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 power down and lock out the machine before changing wheels. Inspect the wheel for cracks or chips before mounting, and never exceed the rated maximum speed of 3600 RPM. Flanges, blotters, and arbor hardware must be clean, correctly sized, and free of damage prior to installation.\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: 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: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\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\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\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 38A80-KVBE\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: 66253043869\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541546762546,"sku":"66253043869","price":99.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3f0d40891290d626165f9ca9d9e8c10.jpg?v=1785879041","url":"https:\/\/voomisupply.com\/products\/norton-66253043869-surface-grinding-wheel-80-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
