Chuck Key

how to remove a drill bit from a dewalt dc740ka DRILL?
sorry i’m having a blonde moment and i really don’t want to call my dad and ask him how to undo the collar… i don’t have a chuck key either and i don’t think you need one for this drill because at college i could undo the drill collar by hand… i didn’t realise they were different!! silly me. can anyone give me some advice if you could it would be great! thanks!
Assuming the drill was made in the last decade, it uses a keyless chuck. Put the drill in reverse and hold the chuck tightly. Press the trigger and the chuck should release. If this doesn’t work, the chuck is over tightened, In that case, you many have to find something to grip both sides of the chuck and turn them in opposite directions. Another option is to find the biggest jock around and let them show off.
