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.
And so I offer to you what I know about drilling holes in metal with a drill press. (When you're planning a project, resist the urge to say, ... and then just drill a hole in it! Good practices will guard the life of your tools. Also, you'll learn a LOT about the qualities and feel of your materials.)
