Women in industry. Tool production. Two to a machine, these young employees of a Midwest drill and tool company are operating cylindrical grinders. This work is delicate and difficult, for the drills must be tapered accurately to size. The drills will be used in manufacture of guns, ships, tanks and in all war production where metal must be worked. Republic Drill and Tool Company, Chicago, Illinois.
