If you don’t already have one of these for your “big” drill, get thee out to pick one up. You probably already have at least one “quick change” drill with an associated bit set, but if not, you will soon. The market’s full of ’em, and they’re extremely handy. But why not allow yourself the option of using them with the standard-chucked tools you already own?
Quick chuck systems like this one from Snappy get convert your standard 3/8” or 1/2″ hex drill or driver to quick release in a few seconds so you can use bits designed for either type. Like the ones you see on small drills, quick change chucks consist of a spring-loaded outer sleeve that when compressed rolls a ball bearing down and out of the way to lock into the bit’s groove. When you release the collar, the spring’s compression pushes the ball up the groove in the shaft and locks the bit into place. Good stuff if you need to switch bits a great deal or have a set of quick releases that work perfectly for the project at hand.
