Broken drill bit is stuck in DeWalt drill

Question

I know this may be a common issue.

I have searched the internet and  so far i am not able to get this broken drill bit freed from my DeWalt drill .

My idea is trying to hammer this bit down but it is very tight I'm not sure I'll be able to.

Any ideas?

edit:
here's a video of what happens when I try to loosen it with a wrench:

Remove chuck with strap wrench (preferable -less chance of damage) or some large pliers (more likely to have on hand)?
