Built around a white aluminum oxide abrasive grain in a vitrified bond matrix, this wheel delivers consistent cutting action and free-cutting performance across a range of ferrous materials. The wheel measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. Grit is 80 with an H hardness code, classified as a medium-grade, semi-friable wheel rated to a maximum of 3600 RPM. Weight is approximately 1.59 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. Typical material applications include soft carbon steels, tool steels, and super alloys. The vitrified bond construction provides rigidity and porosity control, making it a dependable choice for production shops and toolrooms requiring repeatable surface finishes on hardened or unhardened steel workpieces. The 38A Type 1 series designation identifies its grade specification as 38A80-HVBE.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive grain for free-cutting action on ferrous materials\u003c\/li\u003e\n\u003cli\u003eVitrified bond construction for rigidity and dimensional stability during grinding\u003c\/li\u003e\n\u003cli\u003e80 grit, H hardness (medium grade) balances stock removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure promotes self-sharpening behavior under load\u003c\/li\u003e\n\u003cli\u003eNon-porous, non-tapered Type 1 flat wheel profile for standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003eGrade specification 38A80-HVBE for traceability in production environments\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 check for fractures. Power down and lock out the machine before changing wheels, and ensure the arbor hole fits the spindle properly using correct blotters and flanges. Never exceed the maximum operating speed of 3600 RPM.\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\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\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\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrain Friability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Porous\u003c\/strong\u003e: Yes\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\u003eGrade Specification\u003c\/strong\u003e: 38A80-HVBE\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\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: 66252941047\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540044906802,"sku":"66252941047","price":89.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5be1f7f821f0b83049028996bc6bd79c.jpg?v=1785845898","url":"https:\/\/voomisupply.com\/products\/norton-66252941047-surface-grinding-wheel-80-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
