I've seen this done with an impact gun. Put the drill in a
vise. Clamp a 1/2" or 3/8" drive hex bit/key in the chuck,
and use the impact gun to loosen it. Works like a charm!!
If you don't have a hex bit set, any 1/2" or 3/8" drive
screw driver bit usually has a hex shaft that you can clamp
the chuck onto. Good Luck!
