There have been a lot of posts describing what guys have tried.  I don't know what else to say, except use a big - long allen wrench, and either hit it for all you're worth or use a big cheater bar.  Use some clamps or a cushioned vice to hold on the the drill.

my buddy helped me out and put  3/8 inches Socket Hex Bit inside the chuck and put Socket Wrench  and hammer it finally loose  well done
