In the mid-to-late 1920s, electricians and workers in other trades were using Black + Decker tools, and other manufacturers began to develop similar tools for professionals. In 2010, Black + Decker merged with Stanley Works, bringing both companies’ tools under the current Stanley Black + Decker umbrella. Over the years, Black + Decker acquired a variety of companies, including General Electric’s small appliance division as well as toolmakers DeWalt and Porter-Cable. Black + Decker later designed a cordless rotary hammer drill for the Apollo space program, which was used to extract rock samples and could operate at extreme temperatures and in zero-atmosphere conditions. Meanwhile, Black + Decker contracted with Martin Marietta to design tools for NASA, including a zero-impact wrench that turned bolts without spinning the astronaut.

In 1961, it introduced the first cordless electric drill, powered by a nickel-cadmium battery. In 1946, the company introduced the first line of home power tools, including ¼-inch and ½-inch drills, drill stands and accessories. However, World War II brought government contracts for making war material for America and its allies. Like most companies, Black + Decker struggled through the Depression.

Company history cites 1923 as the year it began offering a low-priced, portable electric drill to nonprofessionals. Distribution spreads, company changesīy 1921, Black + Decker was advertising locally, and the company even had a full-page ad in the Saturday Evening Post, targeting a national consumer market. When plant supervisors noticed employees taking drills home to use on projects, they recognized the do-it-yourself market potential. The new product filled a need, and sales increased, but it remained an in-plant tool because there was no home-improvement market and the cost was too high for general consumers. The first drills were intended for industrial use. In 1917, Black and Decker opened a 12,000-square-foot manufacturing plant in Towson, Md., where they made portable electric air compressors, the new drill and other products. Its pistol grip and trigger inspired the new drill.

According to a 1992 Baltimore Sun article, Black and Decker were considering the design of the electric drill they were developing and figuring out how the user could best hold the tool and control the drilling function. Gun manufacturer Colt was among the shop’s clients. Duncan Black and Alonzo Decker established a machine shop in a Baltimore warehouse. Black + Decker’s drill was the first time an electric drill came as a lightweight, portable tool. Electric drills were in operation long before 1916, but they were large, stationary machines used in industrial and manufacturing facilities. The original portable drill, assembled in 1916, is at the National Museum of American History in Washington, D.C.

Both features have been on electric drills ever since. It had a universal electric motor, which could run on alternating current (AC) or direct current (DC) and the pistol-grip handle with a trigger control. (now Stanley Black + Decker) developed and filed a patent application for a ½-inch portable drill that one person could operate. A century ago, the Black + Decker Manufacturing Co. This year marks the 100th anniversary of the portable electric drill’s invention.
