King Tool Co. manufactured the Hercules line of electric drills, ca. 1960, as seen in a 2019 eBay listing. We have found a few ads from 1955 to 1965 for Hercules circular saws and drills, but they are not identifiable as by this company. Another eBay listing in 2020 was for a Hurricane electric drill by Leeds-Fox, Geneva, IL. Any connection between the companies is unknown, other than location.
