It measures 12 inches in diameter, 1 inch thick, with a 5-inch arbor hole, and is dressed with 60-grit aluminum oxide abrasive at a K hardness (medium grade). The vitrified bond provides a rigid, precise cutting action well suited to high-material-removal grinding operations. At 8.4 pounds and a maximum operating speed of 2,705 RPM, this wheel is built for production-level surface grinding work performed by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 32A series aluminum oxide abrasive cuts efficiently across this wide range of ferrous and non-ferrous materials, making it a practical choice for job shops and production floor environments where multiple material types are encountered. Its non-porous, non-tapered, non-recessed Type 1 flat wheel profile suits straight surface and cylindrical grinding setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60-grit aluminum oxide abrasive with K hardness (medium grade) for balanced stock removal and finish\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction for rigid, consistent performance on surface and cylindrical grinders\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess and no taper — straightforward mounting and dressing\u003c\/li\u003e\n  \u003cli\u003eRated to 2,705 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with a broad range of ferrous and non-ferrous materials including stainless, tool steels, cast iron, and aluminum\u003c\/li\u003e\n  \u003cli\u003e32A series specification (60K8V32A) for traceability and consistent reorder\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\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. Never exceed the marked maximum operating speed of 2,705 RPM. Ensure the machine spindle, flanges, and arbor are clean and properly sized for the 5-inch hole before securing the wheel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eGrit\u003c\/strong\u003e: 60\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\u003eSeries Specification\u003c\/strong\u003e: 60K8V32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,705\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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: Blue\/Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.4 pounds\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: 66253246910\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538807259442,"sku":"66253246910","price":97.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5e5c61abbc15d05ba96acd7fff9ea5c.jpg?v=1785827050","url":"https:\/\/voomisupply.com\/products\/norton-66253246910-surface-grinding-wheel-12in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
