: Machinists make metal parts using lathes, drill presses, and milling machines. They often make specialized parts or one-of-a-kind items for companies that produce everything from cars to computers. Most work in machine shops and wear safety glasses and earplugs. Because of the machinery they use and the coolants and lubricants for the machine, this can be a dangerous job.
