I looked at those, but I realized that they really only apply to tapered
brass screws and you need to set the depth precisely to match the length
of the screw.

For assembly work I normally use rolled-thread screws where the shank is
almost the same as the root diameter. The tapered drills don't match
these screws well at all.
