Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal and a controlled surface finish on a wide range of ferrous workpiece materials. The wheel measures 20 inches in diameter, 1 inch wide, with a 12-inch hole size, and carries a 60 grit, medium-grade (L hardness) specification. Rated at a maximum of 1,625 RPM, it is suited for high-volume throughfeed and infeed centerless grinding setups where dimensional repeatability is critical.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on centerless grinding machines configured for cylindrical OD work. It fits production environments such as job shops, precision parts manufacturers, and tool rooms where aluminum oxide abrasive is the standard choice for carbon steel, alloy steel, and similar hard ferrous materials. The vitrified bond provides a rigid, free-cutting structure appropriate for wet or controlled-fluid grinding applications at sustained production rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable performance on ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and consistent cut rate throughout wheel life\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade (L hardness) balances stock removal with surface finish quality\u003c\/li\u003e\n\u003cli\u003eType 1 straight-wheel form fits standard centerless grinding arbors and flanges\u003c\/li\u003e\n\u003cli\u003eNon-porous structure supports controlled coolant application and dimensional stability\u003c\/li\u003e\n\u003cli\u003eMaximum rated speed of 1,625 RPM with specification designation 57A60L-V18\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production consumable for centerless cylindrical grinding machines accepting a 20-inch diameter, 1-inch wide, Type 1 straight wheel with a 12-inch hole bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel mounting and dressing should be performed by a qualified machine operator or toolroom technician following ANSI B11.24 and ANSI B7.1 safety standards. Always power down and lock out the grinder before changing wheels, and inspect the wheel for cracks or chips using a ring test prior to mounting. Use properly rated flanges and blotters; never exceed the maximum RPM stamped or rated for the wheel. Eye protection and a wheel guard conforming to machine specifications are required during operation.\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\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 Hardness)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 57A60L-V18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 20 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: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1,625\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Brown\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\u003eWeight\u003c\/strong\u003e: 23.33 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: 66253246974\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543488889138,"sku":"66253246974","price":1858.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc93f7be9dce3549fad36b0a1c86129f_16d0a6bf-8ce9-4a8a-abbc-2a3bc97cd57d.jpg?v=1785919419","url":"https:\/\/voomisupply.com\/products\/norton-66253246974-centerless-grinding-wheel-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
