The History of the Drill

2016 marks Black & Decker's 100th anniversary. In honor of this momentous occasion, this article is dedicated to the history of drills. Drills are an ancient tool used worldwide to advance human innovation.


Egyptian bow drill.


Bow drills were the first machine drills. Their original purpose was for creating fire, but as time progressed drills began to be used for holding objects together and other tasks. While the official patent of the portable electric drill came about in 1916, the rotary tool itself has existed since 35000 BCE. The bow drill functioned as following: "The bow drill was used for making holes in beads. It had two parts. The first part was a straight piece of reed or stick of wood with a sharp flint tip on the end. The second part was a bow-shaped reed or piece of wood... The sharp tip of the stick was placed in the middle of a bead, and the bow was moved back and forth around the stick to make it turn. The turning action made the tip of the stick drill a hole into the bead." 

Electricity came into the equation in 1889, just ten years after Thomas Edison invented the lamp, when Arthur James Arnot and William Blanch Brain of Australia patented the electric drill. In 1895, C&E Fein  of Germany used an electric motor to power a corded handheld drill.


"In 1916 the company files its first patent for a ½” portable electric drill with pistol grip and trigger switch. This innovation transformed a stationary tool into a portable one and set the cornerstone for today's power tool industry." - Black & Decker


Twenty years later, the electric drill was improved upon by Black & Decker. What started as a tiny machine shop started by Duncan Black and Alonzo Decker turned revolutionary when they combined the design of a Colt .45 automatic pistol with the mechanics of a C&E Fein drill. Thus began the upward climb of the trigger switch, pistol grip, handheld drill.

Storage Is the Key to Solar's Future

"In the drama of renewable energy, no power source has performed better in recent years than solar. Despite improvements in efficiency and lower costs, the future of solar power is still uncertain, and as one researcher suggests, its growth could be its own worst enemy.

Shayle Kahn is a senior vice president for GTM Research. In a paper published in November, he identifies the challenges ahead for solar power.

Entitled 'The Future of U.S. Solar: Getting to the Next Order of Magnitude,' the report notes that solar has been on an impressive growth streak, having gone from 2 gigawatts of cumulative capacity in the United States at the end of 2010 to a likely 26 gigawatts at the end of 2015. He said that solar has addressed one of its biggest pitfalls, high installation costs, which has ensured the industry will be a significant part of the nation's energy mix going into the future,

Kahn said that a number of factors will contribute to the continued growth of solar in the coming years, including rising electricity prices, falling solar prices, the Clean Power Plan, and electricity market innovation.

On the other hand, a number of factors could stand in its way. Perhaps the biggest, and most ironic, challenge will be posed by its own growth.

Referring to an economic scenario known as the value deflation effect, Kahn describes how, as more solar becomes available, its value goes down. This is partly due to basic principles of supply and demand, but it is also caused by solar's inability to flip a switch on or off and trigger generation when it is most needed. Solar can only be generated during the day, when demand is not at its greatest, and as solar begins to occupy a larger space in the market during these times, it has the negative effect of driving its own price downward, providing a disincentive to developers and generators.

The future is still bright despite this scenario. Kahn notes that storage can 'serve the needs of a growing solar market.' He adds that other ambitious efforts could help solar achieve 'the next order of magnitude,' growing from 1 percent of all electricity in the United States to 10-15 percent, 'by 2030, if not sooner.'"

The Effect of Collaborative Robots on the Manufacturing Industry

Conventional thinking would have one believe that the integration of robots into the manufacturing industry led to major losses in human jobs and subsequent blows to the economy. In response to this, robotics technicians have created so called "co-bots," or collaborative robots, that are programmed to work with humans on the manufacturing floor. These innovations have led to positive increases in production and job openings in robot maintenance.

At companies where collaborative robots are used, production rates are higher because of the robot's ability to work without pause. Most collaborative robots also can function without a guarding cage, which takes up space and leeches expenses.   

Humans that work near or with collaborative robots are safe from harm due to the four safety standards that globally identify collaborative robot operation: safety-rated monitored stops, hand guiding, speed and separation monitoring, and power and force limiting. The collaborative robot's awareness of human presence allows them to alert operators of any malfunction or accident instead of simply shutting down.

Although collaborative robots have not yet found their place in the majority of the manufacturing industry, their impact will most definitely expand in the future.
