Built around an aluminum oxide abrasive grain in a vitrified bond matrix, it delivers consistent cut rate and form retention across extended use cycles. The wheel measures 7 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole and is rated to a maximum of 3,600 RPM. At 80 grit and K hardness, it sits in the medium-grade range, making it well suited for applications where a balance between stock removal and surface finish is required. Licensed machinists and grinding specialists typically specify this wheel for flat and surface grinding operations.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Its semi-friable aluminum oxide grain continuously fractures under load to expose fresh cutting edges, which helps maintain a consistent finish on workpieces throughout the wheel life. The 38A series designation places it within a well-established family of general-purpose precision grinding wheels used in both job shop and production environments. It is a non-porous, non-tapered, no-recess Type 1 straight wheel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with semi-friable grain for self-sharpening action during use\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and consistent form retention under grinding pressure\u003c\/li\u003e\n  \u003cli\u003e80 grit, K hardness (medium grade) balances stock removal with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eRated to 3,600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess and no taper — direct drop-in for standard arbor setups\u003c\/li\u003e\n  \u003cli\u003eSuitable for soft carbon steels, tool steels, and super alloys\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 requiring a Type 1 straight wheel with a 1.25-inch arbor hole and 7-inch diameter.

Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each installation — never mount a damaged wheel. Conduct a ring test and run the wheel at operating speed with the guard in place for at least one minute before bringing it into contact with the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 (Straight)\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\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\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\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\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\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\u003eSpecification Code\u003c\/strong\u003e: 38A80-KVBE\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: 1.59 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: 66252941054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538850251058,"sku":"66252941054","price":85.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1b2570db9dd7ff0f7ea4efd7d449775.jpg?v=1785828322","url":"https:\/\/voomisupply.com\/products\/norton-66252941054-surface-grinding-wheel-80-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
