It measures 7 inches in diameter by 1\/2 inch thick with a 1-1\/4 inch arbor hole. The wheel uses an aluminum oxide abrasive grain bonded with a vitrified bond and carries a medium grade with an L hardness code. The 32A80-LVBE specification indicates an 80-grit cut suited for moderate material removal with a controlled surface finish. Rated at 3600 RPM maximum, it is used by machinists and tool-and-die tradespeople on dedicated surface grinders and cylindrical grinders.\u003c\/p\u003e\u003cp\u003eThis wheel is well suited for surface grinding applications in job shops, tool rooms, and maintenance environments. Compatible material applications include 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified structure promotes coolant flow and chip clearance, making it effective for both wet and dry grinding cycles. It is intended for use on CNC cutting tool machines, cylindrical grinders, and surface grinders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess, compatible with standard surface and cylindrical grinding spindles\u003c\/li\u003e\n\u003cli\u003e80-grit aluminum oxide abrasive delivers medium stock removal and a moderate surface finish\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and open structure for effective chip clearance\u003c\/li\u003e\n\u003cli\u003eL hardness code and medium grade offer a balance between wheel life and cut rate on a broad range of metals\u003c\/li\u003e\n\u003cli\u003ePorous construction supports coolant penetration during wet grinding operations\u003c\/li\u003e\n\u003cli\u003e32A80-LVBE specification for consistent lot-to-lot performance\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. Power down and lock out the grinder before changing wheels. Never exceed the 3600 RPM maximum speed rating stamped 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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole 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: L\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\u003eSpecification\u003c\/strong\u003e: 32A80-LVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: 66252940900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541702508850,"sku":"66252940900","price":102.72,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0b1bde41daac7752d53231fe67ae83b.jpg?v=1785882611","url":"https:\/\/voomisupply.com\/products\/norton-66252940900-surface-grinding-wheel-80-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
