Women in industry. Tool production. Pioneers of the production line, these two young workers are among the first women ever to operate a centerless grinder, a machine requiring both the knowledge of precision measuring instruments, and considerable experience and skill in setting up. In this Midwest drill and tool plant, manned almost exclusively by women, centerless grinders have been efficiently operated by women for more than a year, and company production figures have continued to soar.
