Question about Drills
Open the chuck fully and remove the set screw inside it. The screw has left handed threads and is most likely lock-tited in so get a firm grip on it and turn it clockwise to remove it. The chuck is right threaded but put on very tight. The best way to losen it is to lock the short leg of a 1/2-inch allen wrench firmly in the chuck so you can hit the long leg with a hammer. If the spindle below the chuck has flat spots for a wrench, lock the wrench in a vice and put the spindle in it so you can hit the allen wrench hard enough to break the chuck free. When you put a chuck back on use a drop of lock-tite on the spindle and screw threads and turn them on as tight as you can.

I am commenting so this will go out of the active section. When you put the chuck back on just reverse the procedure and hit it a couple times to seat the chuck and reinstall the screw.

I think you will find that if you open the chuck fully you will see a cross head screw inside the chuck which you need to undo before removing the chuck. this secure the chuck from unscrewing while being used in reverse to undo screws. Once this screw is out a spanner is used at the base of the chuck to unscrew it from the shaft. this may need a short sharpe shock to get it to move.
