How to change the drill bit of impact electric drill?
Haha, just hit the aircraft as first line down, put bricks inserted in the line..
Install the drill bit: or the handstand impact drill, the left hand down to the plastic ring, the right hand with the drill, rotating around the insertion
Remove the drill: the impact drill upside down on the ground (bit upward), left hand holding down the drill root plastic ring, right hand holding the drill bit upward, provided when rotating around a bit can be taken out.
