Whenever I'm on a job, I'm always looking for an outlet or an extension cord. So I decided to replace the 6 foot cord that came with my drill, and put in a 25 foot cord.
I want to give a special thanks to Instructables Hall of Famer Phil B. Phil provided me with the advice I needed to do this properly. Be sure to check out his Instructables page.
Open your drill case and take note of the wiring so you can rewire the drill properly. Its best to take a picture so you cant forget it. Be careful to put your screws away as you take them out so you dont lose them.
