drill it out with a drill bit so that you are removing the head of the screw. this will work i have done it many times.

If debris enters the chuck it may no longer turn for adjustment. Spray plenty of wd40 into chuck and allow plenty of time for oil to do its magic. Hold chuck/drill pointing down and turn drill in both directions to clean out debris. If chuck is too far gone, remove the center screw (backwards thread) and remove the chuck(threaded on). Replace the chuck with new generic part from Lowes (about $25.).

If the drill is not too old, I would take it to your nearest factory dewalt repair shop. they have a good warranty on their items. If it is older you probably need to replace the chuck itself. You need to remove the plastic to get the chuck open and then there is a screw down inside the chuck that needs removed. The chuck should come right off and just reverse the process to install the new one.

Open chuck all the way (like for a large drill bit). There should be a set screw at the bottom (where you would put a drill bit). Don't turn too hard - it may be a left handed screw (I don't remember if it is a lefty for sure but try gently each way then with a bit more force each way until it moves).

Good luck.

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.

Hi,

the Chuck should be 2 Part.

Use 2 pair of stillsons Or pipe wrenches, Tight On the 2 Chuck Parts, Crack in opposite Directions.

Alternative, Use Wrench On Chuck Jaw, Short sharp Blow With Hammer.

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.
