If a drill bit is stuck in your DeWalt impact drill, there are a few steps you can try to remove it safely and avoid damaging the drill.
First, try using a pair of pliers to grip the stuck drill bit and gently twist it back and forth. This may help to loosen it from the chuck of the drill. If the drill bit is still stuck, try tapping the end of the drill bit with a hammer or other tool to loosen it further.
If the drill bit is still stuck, you may need to disassemble the chuck of the drill to remove the drill bit. To do this, use a wrench or pliers to loosen the chuck collar and remove it from the chuck. Then, use a screwdriver or other tool to remove the chuck jaws and any other components that may be blocking access to the stuck drill bit. Once these components are removed, you should be able to access the drill bit and remove it from the chuck.
