Built with aluminum oxide abrasive bonded in a vitrified matrix, this wheel delivers consistent cutting action and thermal stability across extended grinding cycles. At 12 inches in diameter, 1 inch thick, and with a 5-inch arbor hole, it mounts to full-size surface and cylindrical grinders. The 80-grit, K-hardness (medium grade) specification suits applications requiring a balance between material removal rate and surface finish quality. Rated to 2070 RPM, this wheel carries the 32A80-KVBE specification designation and weighs 7.97 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for production and maintenance grinding on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. It is a practical choice for tool and die shops, machine shops, and industrial maintenance operations requiring a reliable large-diameter wheel for flat or peripheral grinding work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut rate and thermal resistance\u003c\/li\u003e\n\u003cli\u003e80 grit, K hardness (medium grade) balances stock removal with achievable surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess and standard 5-inch arbor hole\u003c\/li\u003e\n\u003cli\u003eRated to 2070 RPM for use on standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance during wet or dry grinding\u003c\/li\u003e\n\u003cli\u003e32A series designation confirms Norton premium aluminum oxide grain formulation\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 perform a ring test before mounting and confirm the spindle RPM does not exceed the 2070 RPM wheel rating. Power down and lock out the grinder before mounting or removing the wheel. Never exceed the rated speed, and ensure flanges and blotters are clean and properly sized for a 12-inch wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Flat, No Recess)\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\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\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2070\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32A80-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.97 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: 66253262697\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539801538866,"sku":"66253262697","price":287.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c70b3b654f295b3f6a2afa5a495955b.jpg?v=1785844367","url":"https:\/\/voomisupply.com\/products\/norton-66253262697-surface-grinding-wheel-80-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
