Good to know

Always inspect the wheel for cracks or damage before mounting and perform a ring test. Use blotters and flanges of equal diameter, and never exceed the marked speed. A wheel dresser is recommended to maintain flatness and expose fresh abrasive. Store wheels in a dry, frost-free environment away from solvents and moisture.
