how to get screw out of chuck

It should be an allen head screw with machine threads. Place a NEW high quality allen wrench into the head of the screw....not a well worn or rounded off tool....OR a cheap Chinese made soft metal throw away allen wrench.

It should have right handed threads, so hold it securely in one hand then with a quick sharp rap with a hammer hit the allen wrench in a counterclockwise direction. The process may take 4, 5 or 6 tries to succeed.

A second option if you have the tools is to use a 3/8" drive butterfly air tool with the appropriate 3/8" drive long stem allen wrench. Again, hold the drill tightly in one hand and in the CCW direction, energize the butterfly air tool to drive the machine screw out.

I use both methods and haven't lost the battle yet...of course there's always the first....
