Drilling and Clamping – Woodworker Lodge

A drill press chuck should be removed to clean off sawdust or grease every once and a while. It should also be removed if it becomes damaged in any way. The easiest way to remove a drill press chuck is to insert your drill chuck removal tool into the slot on the spindle above the drill chuck. Then take a hammer and tap it in until the drill chuck falls. Make sure to have padding beneath the chuck to prevent it from breaking. It's very important to properly maintain your tools, and drill press chucks need to be regularly cleaned so they can perform well. Recognizing when a chuck needs to be cleaned and safely removing it are two critical skills that woodworkers need to know. What is a Drill Press Chuck? A drill press is a machine that helps you cut cleaner holes into wood. It is used to make perfectly lined holes, holes that have specific depths, and it can cut wheels or bigger circles. The drill press chuck is what holds the drill bit. In some cases, you may need different chucks if the drill bit is bigger or smaller. When cutting out wheels or circles that are a lot bigger, you will still need a chuck that fits the drill bit in the middle of the cutter. To get the right drill bit in the chuck, you will need a chuck key. This key opens the jaws of the chuck so you can insert your drill bit. Once the drill bit is in place, make sure to use the chuck key to close the jaws around it to keep it secure. Make sure you have the right chuck key when ordering or using a chuck. When you look at the image of the drill press chuck below, you can see it has 3 levels. Starting at the bottom and thickest level, we have the shell or sleeve which is what you see on the outside. On the inside of the sleeve is a cylinder opening for it to attach to the drill press. That hole on the side is the drive pin and where you put the chuck key in to loosen or tighten the jaws. Underneath that are the gear teeth. At the tip of the chuck is the jaws, which hold the drill bits in place when they are tightened or loosened. Why You Remove a Chuck One of the main reasons you would need to remove a chuck is to replace it with a bigger or smaller one to fit your bigger or smaller drill bit. Another good reason to remove a chuck is that it needs to be cleaned. The sleeve of the chuck and the spindle can get coated in grease and/or sawdust, which will make it stiff and sticky when you need to add or remove bits. After each use, make sure to wipe off the sawdust and use a degreaser or acetone to clean the grease off. Clean both the spindle and down the sleeve of the chuck. If you mistreat the chuck and don't keep it well maintained, it will get damaged and you need to remove it to replace it.

This is a metal wedge that can change sizes depending on your drill press and the chuck your using. I suggest getting a couple of different sizes to always make sure you have one that works with your chuck and drill press. You will take the drill chuck removal tool and wedge it in a slot above the chuck. Then you will get a hammer and lightly tap the check removal tool. It will then fall out and it is ready for cleaning or replacing. Make sure to have padding underneath your chuck for it to fall on to so you don't damage it. The second way you can remove your chuck is by obtaining a piece of hardwood or metal piping. You will then angle it at the top of the chuck. Then you will take a wooden mallet or rubber hammer and hit the piece of hardwood or metal piping until the chuck falls out. Once again, make sure to have padding underneath so you don't damage your chuck. https://www.youtube.com/watch?v=KbI_7IHAsyw How to Attach a Chuck to the Drill Press To reattach your drill press chuck, you need to make sure it is clean first. Get rid of any and all grease, dirt, sawdust, etc. If it is clean, it is easier to attach it into place. You are then going to slide it back into place up the spindle. You can push it into place and it will be able to stay in place. However, to make sure it is secure, get your wooden mallet or rubber hammer and strike the bottom of it quickly. This will keep it secure while you work and make it less likely to fall out while you work. Listen for it to pop into place. You can also use a piece of hardwood to secure it in place. You'll first put the chuck on and bring the jaws of it up into the chuck to keep it from snagging on anything. Then you will lower the chuck onto the piece of hardwood until it pops into place.
