Measuring 6 inches in diameter by 3\/4 inches thick with a 1-1\/4 inch arbor hole, this wheel carries a 60-grit aluminum oxide abrasive at K hardness (medium grade). The vitrified bond provides rigidity and consistent cut rate, making it well-suited for wet or dry surface grinding where geometry and finish tolerance matter. Maximum operating speed is 4,140 RPM. Machinists, tool-and-die makers, and maintenance technicians are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It mounts on surface grinders, cylindrical grinders, and CNC cutting tool machines. The 32A series designation reflects an aluminum oxide grain formulation that balances cut aggressiveness with wheel life across a broad range of ferrous and non-ferrous materials. It is appropriate for both production grinding and maintenance shop applications where a standard Type 1 straight wheel is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60-grit aluminum oxide abrasive for aggressive stock removal with moderate finish\u003c\/li\u003e\n  \u003cli\u003eK hardness (medium grade) vitrified bond for consistent cut rate and wheel integrity\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess, compatible with standard surface grinder spindle flanges\u003c\/li\u003e\n  \u003cli\u003e4,140 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003eRated for 400 series stainless, carbon steels, tool steels, aluminum, and iron alloys\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.

Power down and lock out the grinder before installing or removing the wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test; do not use a wheel that sounds dull or cracked. Always use the correct flanges and blotters, and allow the wheel to run at operating speed for at least one minute in a protected area before bringing it into contact with the workpiece.\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\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\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: 4,140\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A60-KVBE\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\u003eWeight\u003c\/strong\u003e: 0.26 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: 66252837421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538878923058,"sku":"66252837421","price":109.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3398ff1cf7d907d787c42c93d18a9eca.jpg?v=1785828729","url":"https:\/\/voomisupply.com\/products\/norton-66252837421-surface-grinding-wheel-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
