Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rate and wheel integrity across extended grinding cycles. The wheel measures 12 inches in diameter, 0.5 inches thick, with a 5-inch arbor hole, and carries an 80-grit, medium-grade specification with a K hardness code. Maximum rated speed is 2,070 RPM. This wheel is suited for use by machinists and grinding professionals working in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 66253262111 is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs on a broad spectrum of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified bond structure promotes coolant penetration and chip clearance, making it effective for both wet and dry grinding applications in shop environments where material finish and dimensional accuracy matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for consistent performance on steel, stainless, and cast iron\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure for improved coolant flow and chip clearance\u003c\/li\u003e\n\u003cli\u003e80 grit, K hardness (medium grade) for balanced stock removal and surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel with no recess and no taper for straightforward mounting\u003c\/li\u003e\n\u003cli\u003eRated to 2,070 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eSeries 32A specification: 32A80-KVBE\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or damage before mounting and perform a ring test. Ensure the machine spindle speed does not exceed the wheel maximum RPM rating. Power down and lock out the grinder before changing wheels, and run the newly mounted wheel at operating speed for at least one minute with the guard in place before bringing it into contact with workpiece material.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 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: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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\u003eMaximum RPM\u003c\/strong\u003e: 2,070\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\u003eSpecification\u003c\/strong\u003e: 32A80-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.99 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: 66253262111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541362606386,"sku":"66253262111","price":272.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/98f4b3d9b1bc5bd82539117ce4825c44.jpg?v=1785873559","url":"https:\/\/voomisupply.com\/products\/norton-66253262111-surface-grinding-wheel-80-grit-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
