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.

For that kind of assembly work, I use an 1/8" brad point in an air
drill and #8 low root screws... usually 2".
You don't need a tapered screw to use the tapered bits. In fact, the
further in a regular screw goes into a tapered pilot hole, the better
grab you get. You don't go all the way to the bottom of the hole.
