Measuring 12 inches in diameter, 1-1\/2 inches thick, with a 5-inch arbor hole, this wheel carries a 60-grit medium-grade abrasive structure rated to 2070 RPM maximum. The vitrified bond provides rigidity and free-cutting action, making it well suited for precision surface grinding applications where consistent material removal and flatness are priorities. Machinists, tool-and-die makers, and grinding machine operators typically install and dress this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Its aluminum oxide abrasive and medium hardness rating (Hardness Code K) make it appropriate for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, non-tapered, no-recess Type 1 configuration fits standard surface grinder spindle setups commonly found in job shops and production grinding environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess and no taper for flat surface grinding applications\u003c\/li\u003e\n\u003cli\u003e60-grit aluminum oxide abrasive for aggressive stock removal on a wide range of metals\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity, dimensional stability, and free-cutting performance\u003c\/li\u003e\n\u003cli\u003eMedium grade (Hardness Code K) balances wheel life and cutting rate across varied workpiece materials\u003c\/li\u003e\n\u003cli\u003ePorous structure supports coolant flow and chip clearance during wet or dry grinding\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed rated at 2070 RPM — verify spindle speed before mounting\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.

Power down and lock out the machine before mounting; inspect the wheel for cracks or chips prior to installation and perform a ring test. Never exceed the 2070 RPM maximum operating speed stamped or labeled on the wheel. After mounting, allow the wheel to run at operating speed for at least one minute from behind a guard before bringing it into contact with the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\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: 1.5 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: 60\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: 2070\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\u003eSeries Specification\u003c\/strong\u003e: 32A60-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.96 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: 66253263034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538791399730,"sku":"66253263034","price":518.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89599d51bb164db2a94aed5c8c194976.jpg?v=1785826714","url":"https:\/\/voomisupply.com\/products\/norton-66253263034-surface-grinding-wheel-60-grit-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
