Interesting and unusual facts about a conventional drill The history of the drill + unusual facts about the tool

At the moment, almost no master can do without such a useful tool as an electric drill.

You can even say with confidence that this is the most popular and widespread electrical tool, which is very often used for solving everyday problems, as well as for carrying out construction and professional work.

What is the appearance of an ordinary drill and what it is required for - any person knows. But how exactly she appeared, how she looked before - few know. We invite you to consider when humanity received such a gift of fate as an electric drill, as well as what modernizations and transformations it has experienced.

The history of the emergence of the drill

The creation of an electric motor and its wide distribution has become an incredible impetus for most mechanics, engineers, inventors to create, as well as create electrical tools that were used in industry and medicine.

Interesting and unusual facts about a conventional drill So, for the first time, the mention of an electric drill was back in 1868, thanks to this a mechanic like George Green, a dentist who practiced the design of an electric motor, handpiece, and flexible shaft in a dentist's office.

An American entrepreneur named Samuel White learned about such an unusual development. Since 1872, the company of Samuel White has started mass production of such dental machines. This is how electric drills were first produced for medical purposes, and at the moment such a tool in medical terminology is known to everyone as a "drill".

Until 1894, a prototype electric drill in the form of a drill served in the offices of doctors who treat teeth. This was until the world-renowned electric tool manufacturer and entrepreneur Wilhelm Fein got into the dental chair. His attention was attracted by a machine for drilling teeth, and so he decided to think about changes - for this he connected an electric motor and a drill, without a flexible shaft.

At the same time, the company "Fine" was known on two continents, and its main activities were the development, installation and production of fire alarm systems, telephony, energy, measuring equipment, lighting devices and many others of things.

A year later, in 1895, Fine debugged the serial production of drills with an electric motor.

True, at that moment there was only a two-handed tool with a fairly large size. An interesting episode took place at the same time, because the popular German company Siemens. Halske (she was responsible for telegraph networks around the world, created the world's first electric road, the first tram, trolleybus, meters to Europe, and more) created her own variation of the drill.

But, it is worth noting that such a tool was created and developed for their production needs - an electric motor was connected to a mechanical drill through a belt drive. But Werner Siemens was not interested in producing such a tool.

It is also interesting what Siemens learned over time about the creation of a hand drill at one of its own factories.

Fine's two-handed electric drills have become incredibly popular. Until 1916, the electric drill officially had exactly the design that Fine's company had developed, and then two friends from the United States (Baltimore) decided to get down to business. Alonzo Decker and Duncan Black took inspiration from Fine's drill and the Colt pistol, which was also very popular at the time, so they were able to introduce the world to the first electric drill with a handle like a pistol, a switch (trigger) and a universal electric motor.

This is why Black & Decker became the first manufacturer of electric drills with an improved design and the device has been adapted to maximize ease of use.

in already in 1946 there was another breakthrough in terms of creating an electric tool. For the first time, Black & Decker introduced the world to a portable electric drill that was designed for hobbyists, specifically for home use.

Tooling today

After a while…

… conventional drill with electric motor was modernized and additional "gadgets" appeared: the ability to drill with a blow, reverse, the presence of an electric speed controller, LED backlight, torque control, and more.

There are also models of cordless drills that have ways to work autonomously and not depend on the source of electric current; angle drills have also appeared, which will become an indispensable assistant for work in a hard-to-reach place or where space is limited.

Interesting facts

Let's look at some facts about drills, and you will find out what they were like before the advent of the electric motor:

  • Interesting and unusual facts about a conventional drill Mechanical hand drills can be single-speed and two-speed, and the latter are additionally equipped with a pair of cylindrical gears that give the ability to choose a high or low speed of rotation of the chuck and drill, and the single-speed is much smaller in size.

  • The oldest, primitive drill was found by archaeologists in Turkey, in the province of Bursa, and its age is about 7.5 thousand years.
  • In the USSR, almost everyone used manual meat grinders, but there were those gifted bright minds who combined an electric drill and a meat grinder, which helped to make an electric meat grinder.
  • By the way, there is a chewing dental drill that the Chinese designer Chen Gu was able to develop.

  • For drills, there is a special magnetic drill, which is needed to tighten bolts inside workpieces.

  • The first cordless drill had a 4.8 volts.
  • It was for the drill that a special nozzle was created, which helps to drill walls completely dust-free. There is a ring with blades inside it, which rotates with the drill chuck and the effect of a vacuum cleaner is obtained.

If you also have a drill, do not forget to store the tool in a special box or case.
