How to Trim a Grinder

Metal is capable of being cut using a variety of tools. To trim a small section from a piece of metal you can use an angle grinder. An angle grinder is a hand-held tool that uses an abrasive cutting disc to cut metal. To do this, you first need to determine the amount of metal that you need to trim. You can find an angle grinder at your local home improvement store.
