The portable electric drill has been around for over a century, with its history deeply intertwined with milestones in manufacturing and tool design. While electric drills existed before 1916, they were large, stationary machines used in industrial settings. The first portable electric drill was introduced in 1894, and the era of electric drills began to blossom. However, it was Black and Decker's 1917 drill that truly revolutionized the market with its pistol grip and trigger switch design. This spurred the growth of the modern power tool industry and established Black and Decker as a world leader. The company continued to innovate, including creating the first line of power tools for home users, and developing the first cordless drill in 1961, although it was not widely available. Makita also lays claim to the first cordless drill, with their 1978 design that was accessible to the general public.

Black & Decker's pistol-grip design
Black & Decker is an American manufacturer of power tools, hardware, and home improvement products, founded in Baltimore, Maryland in 1910. S. Duncan Black and Alonzo G. Decker, the company's co-founders, first met in 1906 as 23-year-old employees of the Rowland Telegraph Company. With limited funds, they started a small machine shop in Baltimore, where they focused on improving and manufacturing the inventions of others.
In 1917, Black and Decker designed and patented the first portable handheld electric drill with a pistol grip and trigger switch. The design was inspired by a Colt handgun, which was among the shop's clients. The handgun's pistol grip and trigger were adapted to fit the electric drill, creating an ergonomic and innovative design. This new pistol-grip design revolutionised the power drill, offering more precise control, greater comfort, and improved safety. The drill was also smaller and weighed half as much as its predecessor, making it easier to manoeuvre in tight spaces.
The Black & Decker pistol-grip drill was a significant advancement, becoming the standard tool for drilling holes. It allowed for complex tasks to be completed faster and more efficiently. The introduction of chuck keys further reduced downtime by locking bits into place and preventing slippage or breakage. This drill was first advertised locally in 1921, and by 1923, the company began offering a low-priced, portable electric drill to non-professionals, making it accessible to a wider range of users.
Black & Decker continued to innovate, and in 1961, they introduced the first cordless electric drill, powered by a nickel-cadmium battery. This cordless design provided even greater mobility and convenience, eliminating the need to worry about electrical outlets and reducing user fatigue associated with managing cords. The company's contributions to power tool technology were recognised by the Space Foundation, and they were inducted into the Space Technology Hall of Fame for their achievements in cordless power tools, which were instrumental in NASA's Gemini and Apollo programs.

The original portable drill
The history of the electric drill is a long and fascinating one, with the earliest drill bits believed to date back to prehistoric times. Experts suggest that Homo sapiens were using drill-like tools as early as 35,000 BC, with the first mechanical drill, the bore drill, invented by the Egyptians around 3000 BC. The auger drill, which is still in use today, was invented during the Roman ages.
The first electric drill was invented in 1889 by two Australians, Arthur Arnot and William Bryan (or William Blanch Brain), who paired an electric motor with a traditional drill design. However, this was not a portable drill. The first portable electric drill was invented in 1894 or 1895, with the next revolutionary design appearing in 1917.
In 1917, S. Duncan Black and Alonzo Decker, who had founded their machine shop in Baltimore in 1910, patented a portable hand-held drill with a pistol grip and trigger switch. This design, inspired by the pistol grip and trigger of a Colt handgun, was the first of its kind and quickly gained popularity with contractors and construction workers. Black and Decker's invention spurred the growth of the modern power tool industry, and the company went on to become a world leader in the field.
The Hole-Shooter, a lightweight, one-handed drill developed by A.H. Peterson in 1924, was another significant innovation in the history of portable drills. After a fire destroyed Peterson's facility, the design was acquired by Milwaukee Electric Tool Co., which made it more durable and developed a range of powerful drills for professional users.

The first cordless drill
The history of the electric drill dates back to the late 19th century, with the first electric drill invented in 1889 by Australians Arthur Arnot and William Bryan. However, this was a stationary drill that was too heavy to move. The first portable electric drill was introduced in 1894, and the era of electric drills began to blossom.
In 1917, S. Duncan Black and Alonzo Decker, who co-founded Black & Decker, released a revolutionary electric drill with a trigger switch and pistol handle, marking a significant milestone in the evolution of electric drills. This design quickly gained popularity, and Black & Decker became a world leader in the power tool industry.
The introduction of the first cordless drill to the electric drill market represented a significant advancement, allowing contractors to bring their tools to job sites without the limitation of cords. The inventor of the first cordless drill is a subject of controversy. Many sources recognise Black & Decker as the creator of the first cordless drill in 1961, powered by a nickel-cadmium battery. However, others credit Makita with the first cordless drill design in 1978, as the Black & Decker drill was not widely available or marketed to the general public.
Over time, advancements in cordless drill technology have continued, with companies like Bosch, Milwaukee, and DeWalt introducing innovative features and improvements. The introduction of lithium-ion batteries in 2005 by Milwaukee marked a significant breakthrough, offering extended runtime and enhanced portability.

The Hole-Shooter
The history of the electric drill can be traced back to the invention of the first electric drill by two Australians, Arthur Arnot and William Bryan (or Blanch Brain), in 1889. This early electric drill was created by pairing an electric motor with a traditional drill design. It was not until 1894 or 1895 that the first portable electric drill was invented by the Fein brothers in Germany. This invention marked the beginning of the era of electric drills, with contractors quickly recognising the potential of this new and revolutionary tool.
Over time, various companies released their versions of the portable electric drill, incorporating new design features and improvements. One of the most significant advancements in drilling technology came in 1917 when Black & Decker invented and patented the first trigger-switch, pistol-grip portable drill. This design, inspired by the pistol grip and trigger of a Colt handgun, quickly gained popularity among contractors and construction workers, becoming a staple in the world of power tools.

The bore drill
The invention of the bore drill set the stage for further advancements in drilling technology. Over time, drill bits evolved from being made of wood, bone, or shells to more durable metal constructions, resembling the modern drill bits we use today. This evolution in materials and designs continued, eventually leading to the development of electric drills in the late 19th century.
The introduction of electric drills revolutionised the construction industry, with contractors quickly adopting these powerful new tools. The first portable electric drill was introduced in 1894, and by 1917, Black and Decker unveiled a groundbreaking design featuring a trigger switch and pistol grip, marking the beginning of the modern drill era. This innovative design inspired the creation of various drill attachments, enhancing the versatility of these tools for numerous applications.
