Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal and surface finish on ferrous and non-ferrous workpieces. The wheel measures 16 inches in diameter, 1 inch wide, with a 5-inch hole size, and carries a 60-grit medium-grade specification (57A60L-V18). It is rated to a maximum of 2030 RPM. Machinists, tool grinders, and production grinding technicians install this wheel on centerless grinding machines for high-volume cylindrical part finishing.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for centerless grinding applications in production and job-shop environments. The 60-grit medium grade balances material removal rate with surface finish quality, making it appropriate for intermediate grinding passes on shafts, pins, rollers, and similar cylindrical components. The vitrified bond provides rigidity and thermal resistance under continuous grinding conditions. It is intended for use on standard centerless grinding machines accepting a 5-inch arbor bore and accommodating a 16-inch wheel diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for rigid, thermally stable grinding\u003c\/li\u003e\n  \u003cli\u003e60-grit medium grade (57A60L-V18) balances cut rate and finish quality\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess — straightforward mounting on standard flanges\u003c\/li\u003e\n  \u003cli\u003eNon-porous structure for consistent grinding action across the wheel face\u003c\/li\u003e\n  \u003cli\u003eRated to 2030 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eMedium hardness (Grade L) for controlled wheel wear on a range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement grinding wheel for centerless grinding machines that accept a 16-inch diameter, 1-inch wide Type 1 wheel with a 5-inch arbor bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel installation and dressing must be performed by qualified personnel following ANSI B7.1 safety standards. Power down and lock out the machine before mounting or removing any wheel. Inspect the wheel for cracks or chips before mounting — never install a damaged wheel. Always verify the machine spindle speed does not exceed the wheel maximum RPM rating of 2030 before operating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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\u003eSpecification\u003c\/strong\u003e: 57A60L-V18\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 (L)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Width\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\u003eMaximum RPM\u003c\/strong\u003e: 2030\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14.93 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: 66253246945\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544574656818,"sku":"66253246945","price":401.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc93f7be9dce3549fad36b0a1c86129f_10425101-983b-454b-baa1-891fea1659eb.jpg?v=1785930414","url":"https:\/\/voomisupply.com\/products\/norton-66253246945-centerless-grinding-wheel-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
