Dr E. Douglas Hougen, "The Man Who Invented an Industry", revolutionized the holemaking industry world-wide when he invented the Spotweld Cutter in the late 1950's.

Doug established Hougen Manufacturing, Inc., on February 17, 1959, and began working on a new concept to further revolutionize the hole cutting business. He wanted to go after the steel erection and other industrial markets with his newest inventions. Doug's thinking process eventually resulted in the evolution of the first Rotabroach Annular Cutter
