To remove the chuck on your drill follow the instructions for the type of drill chuck you have:
Instructions for removing a keyed chuck
Most reversing drills have a left hand threaded screw located inside the bottom of the chuck.
1.) If the unit has this screw place the chuck key, with the chuck facing toward you, into one of the holes on the right side of the chuck. Strike the key in a clockwise direction with a wooden mallet or similar object. This will loosen the screw inside the chuck.
2.) Open chuck jaws fully. Insert screwdriver into the bottom of the chuck to engage screw head. Remove screw by turning clockwise this is a left-hand screw.
3.) With the chuck facing toward you place the key into one of the holes on the left side of the chuck. Using a wooden mallet or similar object, strike the key sharply in a counter-clockwise direction. This will loosen the chuck so that it may be unscrewed by hand.
There is no way to stop the motor from turning.
It may require several attempts to loosen the chuck
Instructions for removing a keyless chuck
Most reversing drills have a left hand threaded screw located inside the bottom of the chuck.
1.) If the unit has this screw open chuck jaws fully. Insert screwdriver into the bottom of the chuck to engage screw head. Remove screw by turning clockwise this is a left-hand screw.
2.) Insert the short end of a 1/4" or larger hex Allen wrench into the chuck and tighten. Facing the tool strike the long end of the hex wrench sharply counter clockwise as it is a standard right hand thread. This will loosen the chuck so that it may be unscrewed by hand.
There is no way to stop the motor from turning.

It should have a retaining screw as far as I know. It may be a torx head in this machine though. Normally left hand thread screw, then normal thread for the actual chuck. It's always worth tightening the chuck a bit before removing the inner screw as it can put pressure on it and make it harder to loosen.

Hold the chuck by its sleeve, put the drill in reverse (make sure it's set at high torque if you used it in a drill/driver) and go full speed. That should release the bit.

Use a pipe wrench on it to give yourself a little more leverage. It is simply jammed all the way open and it will release when you apply enough force.

first remove the chuck retaining screw LH thread, next shift the tool to the drill only position and the low side. Find a bent handle allen wrench and insert the short piece into the chuck and clamp down, place the chuck with the long portion at about a 30 degree so you can strike it counter clockwise, usually a block of wood or work bench will do and then get a hammer and safety glasses and hit it, it might take a couple times but it will come off
