Thanks for the post Bob,

What's the make and model number of the tool?

Yes, removing a drill chuck can be a royal pain, sometimes. I know it seems obvious, but make sure you have the correct driver bit and size. Older drills used a Phillips head chuck screw so it seems like that's what you have.

It's most likely a Left Hand screw as well, which means you'll need to turn it clockwise to remove it. Most chuck screws are Left Handed, especially if it's an import drill or a brand like Makita, Bosch or the like. If you're not sure if it's a LH thread or not you can usually look at the parts list and the description will denote this; if not, you can call the manufacturer to be sure.

It also helps to drop some Liquid Wrench or a similar thread loosening product inside the chuck, and leave it there for an hour or two; there's a good chance the threads or rusted.

Once you do this and get ready to remove the screw, you can use a hammer and "punch" the Phillips head bit into the screw head a couple times, as this could help dislodge it. Put as much vertical pressure on the screw head as you turn.

It's easy to strip the head, especially if it's a Phillips head screw; if you do end up stripping the head then you'll be in real trouble, as you'll need to completely destroy the chuck (grind it off) to remove the chuck screw from the female thread in the drill.

I'd say to apply some heat to it with a small propane torch, but you'll end up melting the rubber and plastic (if your drill has a plastic case).

So here's what you're going to need to do since the Screw is removed, but the Chuck is still stuck...

1. Take an L-shaped metal bar that's a good thickness or a larger L-shaped hex wrench that will fit inside the Chuck.

2. Tighten the chuck around the bar/wrench, as tight as you can (like you would a drill bit).

3. Set the Drill on its side, on a very sturdy workbench or (better yet) in a vice.

3. Take a hammer and beat the "L" portion of the breaker bar with a lot of force, Counter Clockwise.

What you're trying to accomplish is this: you're using a "breaker" bar and hammer to smack the chuck off of the threads, which requires quite a lot of force. This is a tried and true method, but it can take quite a few whacks to remove it.

You can see a video of this below, hope this helps!
