Yes sir there is a screw down in the chuck, that holds the chuck to the motor shaft. It's a Torx head screw,

SOURCE: removing the dewalt DC925 'rohm' chuck
I have a DC927 and a DC926 that I removed 1/2" Rohm Supra SK key-less chucks on. This process is pretty simple. Put the drill motor in 1st gear. Put the clutch ring in drill mode and not in driver or hammer. Reverse or open the chuck all the way. Hold the chuck firmly in a vise and give the drill a good POP counter clockwise. The last step can also be done with a pipe wrench by placing the drill on a work bench and turning the chuck counter clockwise. Continue to un-thread until the chuck is removed. The replacement chuck must have the same mounting process and mechanism. Put a few drops of locktite on the threads and thread the replacement chuck back on. Tighten the chuck using the vise or pipe wrench. Place the short end of an allen wrench in the chuck and tighten down on it. Placing the drill on a work bench, strike the allen wrench with a mallet to finish tightening and locking down the chuck. Congratulations, you have just changed out your chuck.
