Shortly after the invention of the electric motor in the 19th century, the electric drill was invented. This creation was patented in 1889 by Arthur James Arnot, an employee of the Union Electric Company in Melbourne. In 1895, German engineer Wilhelm Fein invented the first portable electric drill, and 22 years later, Black and Decker patented a trigger-like switch on a pistol-grip handle. The drills manufactured today have continued to evolve from this original design.

Today, drills are carefully engineered to suit the wants and needs of consumers, and with every manufacturer having a different interpretation of the market, there are many different types available.

The following outlines the four main types of drilling power tools, the accessories to suit, and many frequently asked questions.
