The first power tool is believed to be the bow-powered lathe, invented by the ancient Egyptians which required two people to operate. In the 1890s the first electricity powered tools were invented. Learn more at Trade Service Pro

In 1910, a tool and die worker by the name of Duncan Black sold his car for $600 and used the money to start a small machine shop in Baltimore, Maryland with his friend Alonzo Decker. In 1914, the two arrived at the same idea to improve the C&E Fein power drill by adapting the design of the Colt .45 automatic pistol. By 1916, Black & Decker had begun making their famous pistol-grip, trigger-switch electric drill, from which all modern handheld electric drills are descended.

The Black & Decker drill was not only lighter, but it used a more powerful motor and could be easily operated by one person, two critical features missing from C&E Fein’s original electric drill. After that, the power tool industry was off and running and Black & Decker was soon followed by new companies with new kinds of power tools. A new era of human productivity was born.

NASA – Tools in Space
NASA is often incorrectly cited as the inventor of power tools. As we’ve already discussed, both Fein and Black & Decker should be credited with this.

However, in the mid-1960s, Martin Marietta Corporation contracted with Black & Decker to design tools for NASA. The tool company developed a zero-impact wrench for the Gemini project that spun bolts in zero gravity without spinning the astronaut.
