Built with aluminum oxide abrasive bonded in a vitrified matrix, this wheel carries a medium-grade, 60-grit specification rated at 2030 RPM maximum. At 16 inches in diameter, 1.5 inches wide, and with a 5-inch arbor hole, it suits production grinding applications where consistent stock removal and surface finish are required. The vitrified bond offers rigidity and porosity control, making it well-suited for ferrous metals and tool steels. Licensed machinists and grinding machine operators are the typical installers and operators of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used in centerless grinding setups found in manufacturing and machine shop environments, both in production and job-shop settings. It is configured as a grinding wheel for regulating or work-rest blade setups on centerless grinders handling round stock, shafts, pins, and similar cylindrical workpieces. The 57A60L-V18 specification indicates an aluminum oxide abrasive composition, L-hardness rating, and vitrified bond type, making it appropriate for medium-pressure precision grinding on steel and similar ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for effective stock removal on ferrous metals and alloy steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides wheel rigidity and dimensional stability under grinding loads\u003c\/li\u003e\n  \u003cli\u003e60 grit, medium grade (L hardness) for balanced material removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess, compatible with standard centerless grinder flanges\u003c\/li\u003e\n  \u003cli\u003eRated to 2030 RPM maximum for safe operation on appropriate centerless grinding machines\u003c\/li\u003e\n  \u003cli\u003eNon-porous construction for consistent grinding performance across the wheel face\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit grinding wheel for centerless cylindrical grinding machines accepting a Type 1 wheel with a 16-inch diameter, 1.5-inch width, and 5-inch arbor hole.
