I just drilled some boards last night. I did some experimenting with the position of the lamp and found that if I placed it behind the drill stand shining down on the board from the opposite side I was sitting, it was much easier to perceive the depth and the process went a lot quicker. I've finally actually managed to wear out a carbide bit, prior to building a specialized drill I always broke them before they ever dulled.
