As technology continues to advance, more and more power tools are emerging to improve efficiency and replace heavy physical work, it is no exaggeration to say that the emergence of power tools has changed the face of the world. Tools are instruments that give humans mechanical advantages. In the animal world there are many birds and primates that also use tools, but there is one thing that sets us apart from them and that is power. Unlike the rest of the animal kingdom, we humans rely on more than just our physical strength and can power our tools through other sources of energy.

We may not have superpowers, but we do have power tools. Power tools are used in every aspect of our lives in medicine, manufacturing, construction, rescue, etc. In the 19th century, the Industrial Revolution, factories utilized gas steam and electricity to give more power to their tools, and since the 1960s, power tools have been reinvented to be used in the average home. Power tools have a market share of $23.4 billion. About 40% of this comes from North America, 22% from Asia, and 27% from Europe, with power tools accounting for about 75% of all power tools sold.

The power of a power tool depends on how much voltage it can withstand; think of voltage as water pressure; the more pressure the water manages, the stronger the jet will be. The same goes for voltage, the more volts in the tool, the more power the tool can produce. To get enough voltage also meant being plugged in, however the discovery of batteries changed all that. Battery-powered tools were first used on the moon, in the 1960s. Apollo astronauts needed a small handheld power drill to drill into the lunar surface to collect soil samples, first applied to a handheld cordless vacuum cleaner introduced in 1979. It then sparked a revolution in home power tools.

The power tools we know and use run on human energy, electricity, gasoline and compressed air, but the tools used by professionals are much more powerful. It's not uncommon to see race car pit crews using pneumatic wrenches to remove tires at auto racing events, where there are time constraints and they're scrambling to save time. A pit crew can remove the nuts on four tires in as little as 12 seconds because the Thundergun wrench can spin at 25,000 rpm in one minute. It's powered by compressed air, compared to a standard pneumatic wrench with 2,000 revolutions per minute. The speed of the Ray Gun is 12.5 times faster than that of the standard pneumatic wrench, and this speed can remove a tire nut in less than 0.2 seconds. If a standard pneumatic wrench is used. Instead of a Ray Gun then the 12 seconds to change a tire becomes three minutes.

In the 19th century there is a legendary story, in which the main character called John Henry is a construction of the railroad workers, this worker is the strongest workers at that time, his job is to drive nails into the railroad tracks, then no one can match him, and then a kind of power tool was born, the emergence of the air hammer so that people no longer need to use brute force to hit the nails. The worker fearlessly challenged the hammer, and the man-machine war began. Who could hammer faster? In the end, the human Henry won. But he died not long afterward because he had overdrawn his strength. Of course, this is just a legend. In this day and age, even the commonly used hammers and nails are not immune to the elimination of human progress.

The advent of a new power tool, the nail gun, which is at least ten times faster than a hammer and can shoot 100 nails per minute, far exceeding the efficiency of human labor. Then there's our most common chainsaw with a two-stroke starter engine, which is small but has a powerful engine that can drive equipment like lawnmowers and motorcycles. When using a chainsaw the operator only needs to pull the cord to start the starter engine, which drives the steel teeth on the saw chain to cut through the wood, these power tools have revolutionized the construction industry.

Of course, in addition to being used for manufacturing work, power tools can also be used to save lives. Power tools can also achieve surgical precision, and in the past surgeons have shifted from performing major resections to minimally invasive surgery, and in order to achieve this surgeons need technological support. And technology often means the need for power tools, we all know that surgeons do surgery and make incisions with scalpel blades, the problem is that incisions like that bleed, and now there is a power tool for surgery. It cuts and coagulates wounds using high temperatures just like a scalpel. Coagulation means stopping the bleeding, which is very important for surgeons. It's the human drive to turn materials into never-ending high-tech equipment that puts real power into power tools.
