Ways:
WD40 and a long soak.
Impact-driver or whacking the screwdriver with a hammer.
Blow-lamp
Combinations of the above.
But do you need to take it apart to clean it?

You might be able to force oil/grease in, but if it's not going to come apart you'd have to live with that. L

If you whack the screw you may jar-loose some of the corrosion, or you may not. It's an option, but look at the thing and decide whether hitting it might loosen it up. L

They're springy rather than brittle. Does it have holes for expanders/compressors? You can usually wangle them with a screwdriver though...

Oh good. Might not be entirely appropriate for a Yorkshireman, but hammers are sometimes known as "Manchester screwdrivers"... L

Drill the head of the screw out. then you should be able to get the case apart. Now if you're lucky you can get pliers on the screw. If not then grind the screw level and drill that out and retap or use a self tapping screw to replace it.

There is a good reason to read all of the answers before you try the first one. I naturally jumped to a conclusion and assumed that the screw was in fact seized. And interpreted that you had probably also stripped out the slot or cross and the screw driver could not grip anymore. Now, if that is in fact not the case, then you should by all means try all of the other well thought out plans. My plan is the next to last one to the other one is to not fix the drill at all or chuck it and get a new one. Is the drill case aluminum? If so and the bolt is steel it might really be seized since steel is easy to seize in aluminum with out anti-seize grease. As a last resort to try fixing it if it comes down to it, my method can be very useful and easy to do. My first attempt was successful after I had twisted of a valve cover bolt on my first car at 14. I dad told me how to do it, gave me the tools, and and told me "you broke it you fix it". Maybe you'll have better luck with your project and if you don't then you might learn something.

Before you go all medieval on the screw, do one thing, try loosening the screw by turning it to the right. Seriously. You may be dealing with a left-hand threaded screw. Most Jacobs chucks are secured with one.

Yeah, I got that, I was just using the chuck as an example. If the gear's normal rotation is counter-clockwise, its feasible that it would have a securing screw with left-hand threads. Just thought I would mention it.

Try dropping a bit of WD-40 in there and let it sit for a while. Repeat. An hour or so later try turning the screw.
