Drills are one of the most commonly used tools and a good drill index is essential to most scratchbuilding, kitbashing, and layout construction work. Notice the baby drill index in the upper right. These drills are really too small to be used in a power drill, so a pin vice (laying across the drill index) is used to hold and turn them.
If you are going to tap threads in drilled holes or cut threads on rod stock, they you'll need some taps, dies and the appropriate handles. The secret to successful tapping is to go slow, go back a quarter turn for every half turn forward and use plenty of cutting oil. There are special oils formulated for cutting (usually containing a lot of lard) but for most work on soft metals, you can get away with ordinary light oil such as 3-in-1 oil or even motor oil.
