Because of the First World War, Wegener's book went unnoticed outside Germany. In 1922, however, a third (revised) edition was translated into English, French, Russian, Spanish, and Swedish, pushing Wegener's theory of continental drift to the forefront of debate in the Earth sciences.
A drilling machine, called a drill press, is used to cut holes into or through metal, wood, or other materials (Figure 4-1). Drilling machines use a drilling tool that has cutting edges at its point.
You can drill by hand, but the drill press saves you so much stress because it keeps the drill perfectly in place as you're boring through the glass or stone. The last component that you would need to get is a diamond drill bit. I use 1.2 to 1.5 mm bits, and I buy at least three at a time because they are breakable.
