jacobs come out with this all metal keyless chuck(i think thats what you have) and if thats the case, there is no solution for this youll have to replace the hole chuck, being its new, it may be under warrenty

SOURCE: keyless chuck is stuck with bit inside

Try two channel lock pliers.
Hold the bit close the the base with one.
Take the other (cloth comes in handy here to prevent marring) and turn the chuck counter clockwise to release.

Alternative (little WD40 on the chuck)
One channel lock plier hold the chuck and put the drill in reverse.
The WD40 should allow the chuck to release easier.

Good luck!
