Drill chuck keys are used to tighten the bit to the chuck, and each key is designed to match up with the post, the angle and the tooth count. Understand the importance of a chuck key with help from a custom furniture maker in this free video on woodworking tools.
Hi I am Dave Trull with the Trull Gallery a custom furniture shop in St. Petersburg, Florida, and I am going to talk to you today about how to use a drill chuck key. Real simple you are going to find that on most of your drill presses. It is getting harder and harder to find one on a hand drill. Those are mostly going with keyless chucks. We going to go ahead and talk about a key chuck today. First thing we want to do is open our chuck up enough to get our drill bit in, and then we can go ahead and manually close it until we are just snug. That is where our chuck key comes in, and one thing you want to make sure is that your chuck key matches your chuck. There are different sizes of keys you need to match both the post, and the angle and tooth count. It is really best to go with your manufacturers key. If you do get an after market key say you lost yours make sure that you do the best you can to match it up or you are going to strip out either your key or your chuck. And to use it simply set it into one of the three holes, and turn, and it is tightness clockwise. And for most drills you can just use one hole. If it is an older drill with the individual teeth move separately you may want to just go back and hit all three just to make sure you get an even tightness. And it is as simple as that. Real quickly that is how to operate a drill chuck key. I am Dave Trull with the Trull Gallery, the fine art of furniture making.
