How to Use a Lathe Drill Chuck
One of the most important aspects of using a lathe is the drill process. Lathes are specifically designed to use drill chucks for cutting holes in the center of fast moving pieces of metal, wood or plastic. By cleaning the chuck and inserting it into its place properly, you can cut large or small holes with ease and accuracy.

Clean the shaft of the drill chuck. It is important that the shaft be cleaned and all metal chips and debris removed before placing in the tail stock of the lathe. The tail stock is the block located on the right-hand side facing the lathe. It is on center with the spindle and will drill on center with any piece within .002 inches if aligned properly.

Push the drill chuck into the hole in the front of the tail stock. This area is specifically there for holding drill chucks. It has a tapered collet area specifically designed to hold tapered shanks. If your drill has a straight shank, you must use a specially designed tapered holder or change the shank to a tapered version.

Lightly tap the drill chuck with a rubber mallet to seat it into the tail stock properly. Too much force will make it difficult for you to remove the chuck when you are finished, but you do not want the drill chuck to come loose during drilling as it may cause damage or injury.

Loosen the jaws of the drill chuck to allow the insertion of a drill with a chuck key or by hand with a key-less drill chuck. If a chuck key is needed, insert it into the hole on the side of the chuck, and turn counterclockwise to loosen the jaws. Drill chucks come in a few sizes and can hold drills as small as 1/64 inch all the way up to 1 inch.

Insert the drill in the chuck as far as possible, but make sure that all of the flutes, which are the cutting areas, are exposed. Hand tighten the drill chuck, and use the key to further tighten the drill. Make sure that it is not twisted in the chuck. Look at the chuck from the front of the drill as it is often difficult to determine if the drill is right from the side view.
