Break out the inside of the electric hammer drill? The part that might be broken is out of shape and cannot be taken away
You do not know what brand, what type of hammer, if you can put down the drill bit grip is taking place, and then use the other electric hammer (with a drill must be small) from the drill sleeve behind the impact drill sleeve inside the drill, quickly down,
In this case, the front reduction head should be removed and there is a 5mm through hole in the drill chuck. The locking sleeve will be pressed down and then the other end will be washed out with a steel screwdriver
