Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and shape retention across extended use. The wheel measures 6 inches in diameter and 1\/2 inch thick with a 1\/2 inch arbor hole, and is rated to a maximum of 4140 RPM. At 80 grit with a K hardness (medium grade), it suits controlled material removal on soft carbon steels, tool steels, and super alloys where surface finish and dimensional accuracy both matter.\u003c\/p\u003e\n\u003cp\u003eThis wheel fits standard surface grinders, cylindrical grinders, and CNC cutting tool machines. The 38A series aluminum oxide formulation is a common choice in tool rooms and production grinding applications where the workpiece material is sensitive to heat buildup. Semi-friable grain structure allows the wheel to self-sharpen during use, helping maintain cut rate on harder tool steels and super alloys without excessive glazing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive, semi-friable — self-sharpens during grinding to maintain cut rate\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid wheel structure and precise form holding\u003c\/li\u003e\n  \u003cli\u003e80 grit, K hardness (medium) — suited for controlled stock removal with acceptable surface finish\u003c\/li\u003e\n  \u003cli\u003eRated to 4140 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eNon-porous, no recess, no taper — standard Type 1 straight wheel geometry\u003c\/li\u003e\n  \u003cli\u003e38A series specification: 38A80-KVBE\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 before mounting and perform a ring test per ANSI B7.1 guidelines. Power down and lock out the machine before changing wheels. Do not exceed the maximum RPM stamped on the wheel or listed in the manufacturer documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\u003c\/li\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A80-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\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: 6 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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 4140\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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: 1.2 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: 66252836548\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543773806898,"sku":"66252836548","price":76.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a56e2a09af1578bfeadbc3e2f90d31e.jpg?v=1785921763","url":"https:\/\/voomisupply.com\/products\/norton-66252836548-surface-grinding-wheel-80-grit-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
