In 1918, Henry Ford, the great car manufacturer, placed an order with a young manufacturer, A.H. Petersen, who was one of the company's tool suppliers. His brief was to develop an electric drill that would be lighter than those already in existence. Petersen took up the challenge and created the Hole-Shooter, capable of the same performance but requiring less effort from the workers. In 1922, he founded the A.H. Petersen Company with his partner, Siebert, who bought the company when it went bankrupt in a fire. He began by repairing tools: this enabled him to train his employees well and to understand the needs of users by being in contact with them. He developed all kinds of power tools that were powerful, durable and lightweight. Soon, the US Navy was adopting Milwaukee power tools. The company also launched new ranges of chipping hammers, belt sanders and jig saws, including the famous SAWZALL... In 2005, the company joined the international Techtronic Industry group, which owns major brands such as AEG, Hoover and Ryobi.
