Constructed with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and thermal stability throughout the grinding cycle. The wheel measures 12 inches in diameter, 1\/2 inch thick, and carries a 5-inch arbor hole, making it sized for industrial surface grinders and cylindrical grinders. At 60 grit with K hardness (medium grade), it balances aggressive material removal with acceptable surface finish on production workpieces. Maximum operating speed is 2070 RPM. Rated weight is 3.99 pounds.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding operations in job shops, tool rooms, and production grinding cells. It is appropriate for use 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 and CNC cutting tool machines. The porous structure of the vitrified bond allows coolant penetration and chip clearance, reducing heat buildup during aggressive passes on hardened steels and cast materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain for broad metal compatibility including stainless and carbon steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure supports coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003e60 grit, K hardness (medium grade) balances stock removal rate and surface quality\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel with no recess — straightforward mounting on standard arbors\u003c\/li\u003e\n  \u003cli\u003e5-inch arbor hole fits common industrial surface and cylindrical grinder spindles\u003c\/li\u003e\n  \u003cli\u003eSeries designation 32A60-KVBE provides positive identification for reorder and compliance documentation\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.

Always inspect the wheel for cracks or chips before mounting — perform a ring test per ANSI standards. Power down and lock out the grinder before changing wheels. Never exceed the 2070 RPM maximum operating speed marked on this wheel; confirm the machine spindle speed before starting the grinder.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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\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\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\u003eMaximum RPM\u003c\/strong\u003e: 2070\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\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: 3.99 pounds\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: 66253262107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541950169394,"sku":"66253262107","price":313.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a26047dbbe6d787b18541b93b0d3930.jpg?v=1785888318","url":"https:\/\/voomisupply.com\/products\/norton-66253262107-surface-grinding-wheel-60-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
