How tough is a Porter Cable drill driver?
Tough. Dropped my 20 volt brushless about 7 feet off the ladder today. Climbed down, figuring I'd have to go get the corded drill. Picked it up, squeezed the trigger, and sounded like a jack hammer, but it still ran. OK, so, nothing to lose - use it. I was driving steel roofing screws, and the racket it made was horrible, but it ran. Since it was 2 or 3 years old, didn't owe me much. so kept on, figuring I'd see if they were still available, as they have wicked long battery life.
Lo and behold, after about 10 or 12 screws, the noise quit, and it kept on going like nothing had happened. Finished the roof, still going.
Alexis de Tocqueville was a very smart man.
