Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and shape retention under demanding shop conditions. It measures 7 inches in diameter, 1\/2 inch thick, and carries a 1-1\/4 inch arbor hole. The 80 grit, medium-grade construction with an H hardness code keeps the wheel from loading on harder workpieces while still providing an efficient cut. Rated to 3,600 RPM, it is suited for production and maintenance grinding operations performed by machinists and tool-and-die tradespeople.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines in both job-shop and production environments. The porous, vitrified structure promotes coolant retention and chip clearance, making it a practical choice for wet or dry surface grinding applications where finish consistency matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut rate and wheel shape retention\u003c\/li\u003e\n\u003cli\u003e80 grit medium grade with H hardness code — balances stock removal with workpiece surface integrity\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes chip clearance and coolant flow during grinding\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel geometry with no recess for broad surface grinder compatibility\u003c\/li\u003e\n\u003cli\u003eRated to 3,600 RPM for standard surface and cylindrical grinding machines\u003c\/li\u003e\n\u003cli\u003eSeries designation 32A80-HVBE for specification-driven replacement and procurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Always power down and lock out the machine before changing wheels. Inspect the wheel for cracks or chips before mounting — never use a damaged wheel. Confirm the machine spindle speed does not exceed the 3,600 RPM rating marked on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 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: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\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: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\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: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A80-HVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 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: 66252940894\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540927807794,"sku":"66252940894","price":89.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/216160a15889418b462ae8e98c9e9e81.jpg?v=1785866014","url":"https:\/\/voomisupply.com\/products\/norton-66252940894-surface-grinding-wheel-80-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
