Wheels (especially vitrified or glass-based wheels) are easily damaged if they are bumped or dropped.That is why it is so important to carefully store and handle them.

1.Check all wheels when they are received and before using them.
2.Follow the manufacturers instructions for storage. Figure shows how and where to store  different types of wheels. Proper sorting and storage of grinding wheels will help to ensure easy access, less handling, and less chance of error.
3.Store grinding wheels in an area that is dry and protected against damage from impact, solvents,high humidity, and extreme heat or cold.
4. Store portable grinders on hooks or in V-shaped racks. Protect racks against damage.
5.Arrange grinding wheels so that older ones will be chosen before newer ones.
6.Never roll a wheel on its edge; it may absorb oil or dirt from the floor, and get damaged.
