All this talk about corded drills...
Back in the day before cordless drills were widely available, I used to make rustic furniture. Everything was held together by lag screws and other large screws. I was wasteing a lot of time changeing bits.
So I went to the Back and Decker service center. This was the days when it was a good brand. They had a line of industrial tools. I bought three half inch rebuilt corded drills. I think they were $40 each. For a few bucks more, they gave me a really long cord for each. The cords were interchangable and could be used as an extension cord in a pinch.
I needed three drills. One was to countersink the lag screw. One to drill the pilot hole. And one to drill out the hole for the shank of the lag screw. I taped the chuck key onto the cord close to the drill. When I was working, I was very efficient with the three drills.
I beat the hell out of those drills for years. They never faltered. I eventually lost one and gave one to a friend. I still have one, 35 years old! And it was a rebuilt one too. It is still strong as a horse, though not quite as strong and quick as it was many years ago. (I think we all suffer from that problem.)
About 15 years ago, I bought a 9.6 volt makita. I liked the clutch in it for driving screws. It has done just fine for me. I will be using it in my office in the next couple of days for some minor repairs. Just charge up the battery and it is good to go.
I am not sure what I would use if I was ever to get back into any kind of production. But those old, orange, rebuilt Black and Decker corded drills built well over a hundred, big rustic furniture pieces.
