When you want to remove a screw.
Most power drills have a reverse switch near the trigger.
If you have the drill in your hand with the chuck away from you, if the rotation goes clockwise it is going forward and if it is counterclockwise it is going in reverse. When you use the drill you usually go forward. To remove the drill bit look for the reverse lever and once it is going counterclockwise place your hand on the front part of the chuck and the drill bit should be released.
