What is this?

Yes! A chain drill. They are very beautiful and effective tools. You put the chain around the back of the pipe and slide it into the slot on the other side of the drill. Then when you use a brace to twist this thing, the threading in that central shaft pulls the bit slowly and steadily into the metal. It really makes drilling very easy and effective. With a chain drill like this, you can drill holes in metal by hand about as fast as with a modern electric drill.
