Archimedean Drill

The archimedcan drill, also called the fret drill, is the perfect drill for boring small holes in thin wood. In fact it is, as the name suggests, designed to be used in conjunction with a fret saw, making '16-inch-diameter holes through which the fretsaw blades are threaded. The top handle of the drill is held and supported in one hand, while the lower handle is pumped up and down with the other. If you have in mind to make musical instruments, fine fretwork, very small toys or the like, then this the tool for the job.
