Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal on ferrous metals and hard alloys. The wheel measures 3 inches in diameter by 1\/2 inch hole by 1\/2 inch thick and is rated to a maximum of 10,825 RPM. Medium grade with K hardness provides a balanced cut that holds form well under moderate to heavy grinding pressure. Grinding professionals and tool-and-die shops rely on this wheel for tight-tolerance internal work.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for internal cylindrical grinding applications in industrial and job shop environments. It is commonly used in jig grinders, internal grinding machines, and ID grinding fixtures to finish bores, bushings, and cylinder bores to specified tolerances. The vitrified bond allows for coolant use and maintains wheel integrity at operating speeds. Its compact 3-inch diameter makes it well-matched for small-bore finishing passes where wheel clearance is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for reliable performance on hardened steels and cast iron\u003c\/li\u003e\n  \u003cli\u003eVitrified bond supports coolant use and resists heat distortion during grinding\u003c\/li\u003e\n  \u003cli\u003eMedium grade, K hardness rating provides consistent cut rate with good wheel life\u003c\/li\u003e\n  \u003cli\u003e60 grit delivers a medium surface finish suitable for semi-finish and finish grinding passes\u003c\/li\u003e\n  \u003cli\u003eRated to 10,825 RPM for use on standard internal grinding spindles\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel geometry for straightforward mounting and dressing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fitment grinding wheel for internal grinding machines accepting a Type 1 straight wheel with a 1\/2-inch arbor hole and 3-inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified grinding machine operator or machinist. Always power down and lock out the grinding machine before mounting or removing the wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B7.1 standards. Never exceed the maximum rated RPM of 10,825; verify spindle speed before operation.\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\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 Rating\u003c\/strong\u003e: K (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\u003eWheel Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 10,825\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.09 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: 66243528828\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542544810290,"sku":"66243528828","price":24.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4840e9281559924d6d6e08a373385cb.jpg?v=1785903335","url":"https:\/\/voomisupply.com\/products\/norton-66243528828-internal-grinding-wheel-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
