A Collet Chuck on The Lathe

A Collet Chuck is a clamp that holds the stock you are working with in the lathe. The Collet Chuck should be used for stock that is that is smaller and either cylinder shaped, hexagon cylinder shaped, or squared shaped. It is important to turn on the lathe ""IF SAFE TO DO SO"" after clamping your part to check that your part is in square and didn't get clamped down crooked. If there is a size of collet for the part the collet should be used for the part because they will hold the part more securely, this is because the Collet Chuck will be contacting on almost 100% of the part giving a more stationary part. It will also help make the finish look much better instead of the jaws making a mark on it.
