Hi! I'm Dave Trull with The Trull Galleria, custom furniture shop in St. Petersburg, Florida, and today I'm going to show you how to remove a drill chuck. Drill chucks can be kind of tough to remove, there's a lot of torque on them. So you're going to have a little patience with them, and sometimes it doesn't hurt to call your manufacturer, and find out exactly what's what. Most of the chucks on the market today will have some kind of fastener in the center. In this case, there is an Allen screw down in the center, and we need to pull that out. So go ahead a remove that. Actually we need to do is just to go ahead and unthread the chuck from the body which is easier said than done. In most cases, you're going to need a large Allen wrench, and lock that down in your chuck the best you can, and I went ahead and call the manufacturer of my drill to find out. Is this a standard thread or reverse thread? And they told that this was in fact a standard thread so I want to go counterclockwise to remove it. And if you just turn it, it's not going to do anything because the chuck is on the thread, it's nice and tight, going into the body. So what you need to do is get a really nice, quick, sharp strike to get that just right. Don't be upset if, you know, you find out that it is. You're going to correct direction but it's not budging, you may have to take two or three whacks. It took about three whacks to get this off yesterday. Then you go ahead and loosen that, pull this out, and replace your chuck (and replacing it is just the opposite), thread it back on, return that screw to the center, and you're good to go. Real quick and simple, that's how to remove a drill chuck. I'm Dave Trull with The Trull Gallery to find out the furniture making.
