Built from aluminum oxide abrasive with a vitrified bond, it delivers consistent cut rates and good form holding across a range of grinding applications. The wheel measures 6 inches in diameter, 1\/4 inches thick, with a 1-1\/4 inches arbor hole. At 80 grit with a K hardness code (medium grade), it is suited for moderate material removal where surface finish and wheel life need to be balanced. Rated at 4,140 RPM maximum, it is appropriate for standard-speed surface grinders and cylindrical grinding setups.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on hard carbon steels, soft carbon steels, and tool steels. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The 32A series vitrified aluminum oxide construction is a standard choice for tool rooms and production grinding cells where consistent performance on steel alloys is required. The porous structure aids coolant flow and chip clearance, reducing heat buildup during extended grinding passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for use on carbon steels and tool steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and consistent form holding\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eK hardness code suits a wide range of ferrous workpiece hardness levels\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure supports coolant delivery and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess for straightforward mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks using the ring test and confirm the spindle RPM does not exceed the 4,140 RPM maximum marked on the wheel. Power down and lock out the grinder before changing wheels. Never force the wheel onto the arbor or overtighten flanges, as this can cause fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole 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: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 4,140\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 (Straight, No Recess)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32AA80-KVTR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hard Carbon Steels, Soft Carbon Steels, Tool Steels\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: 66252835092\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543047799090,"sku":"66252835092","price":81.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50931af06560993e573a8da05271932d.jpg?v=1785914493","url":"https:\/\/voomisupply.com\/products\/norton-66252835092-surface-grinding-wheel-80-grit-6in","provider":"Voomi Supply","version":"1.0","type":"link"}
