Bulgarian scientific name. "Bulgarian" - the history of the name and the secrets of choosing the right instrument. What is Bulgarian video
We sometimes get so used to the unusual names of the surrounding things that we are not curious about the origin and history of the name. And yet it is interesting to know why the grinder is called the grinder. Curious details about the instrument itself and its name look further!
Why is Bulgarian called Bulgarian?
The explanation here is simple. Much in Russian speech gets its name depending on the country, region, area from where it came to our open spaces. As an example, let's take a polka dance, a finca - a Finnish knife, a Dutch stove (built on a Dutch model).
It is now approximately clear to the reader why the grinder is called so. In Russia, this handy tool was first supplied from Bulgaria.
An interesting fact: except for the Russian Federation and a number of post-Soviet countries, nowhere in the world this device not called Bulgarian. Its official name is used - angle grinder.
Name history
Knowing why the saw is called a grinder, let's delve a little into the history of the common name. For the first time this tool began to be delivered in Soviet Union back in the 70s. The importer was the friendly USSR socialist republic Bulgaria.
Soviet users of the tool, seeing the name of the country of manufacture on the nameplate, soon dubbed the saw itself a grinder. The direct manufacturer of the device was Sparky Eltos. I must say that it continues its work even now. You can easily find Sparky products on the market for similar products.
I must say, today this brand is not particularly relevant. On the market, his products are classified as semi-professional. However, in terms of cost, they are not inferior to professional tools produced by such famous brands like Bosch, Hitachi, Makita. However, "Sparky" has ardent adherents who prefer devices only from this manufacturer.
Another explanation for why the grinder is called the grinder. In the seventies in the USSR there was a shortage of goods in its heyday. Therefore, on the shelves of the stores there were only tools from the Bulgarian supplier "Sparky". Since there were no other importers or manufacturers, the device was destined to receive the capacious name "Bulgarian".
If we turn to the history of those years, we will see another fact that contributed to the establishment of this name of the instrument. Why is Bulgarian so called? Many Bulgarians came to Soviet construction sites then. Many of the workers had their own tools with them.
Today, similar instruments in everyday speech out of habit are called the same way. Bulgarians will be devices of both domestic and any other foreign production.
What is the correct name?
Let's now get acquainted with the official name of the instrument. This is an angle grinder. Agree, "Bulgarian" sounds simpler, much faster to remember.
But the tool has another, less well-known, but also a curious name. angle grinder sometimes in colloquial speech called "monkey".

Almost any man uses an electric tool as needed - to cut something, grind, drill. One of the most popular electrical mechanisms for performing various works is angle grinder (angle grinder).
Why is an angle grinder called a grinder?
An angle grinder in the common people is also called a grinder. To understand where this name came from, you need to dig a little into history.
In the Soviet Union, the word "Bulgarian" appeared in everyday life in the late sixties of the last century. At that time, far from us, the Bulgarians bought a license from Bosch for the production of angle grinders. Since the goods of the capitalist countries were not available in the USSR, this instrument of Bulgarian production appeared in the fatherland. At that time Bulgaria was a country of the socialist community, and we had well-established trade relations with this state. Therefore, in the USSR, first of all, angle grinders of this country appeared, hence the name. An instrument from Bulgaria began to be called a "grinder".
Types of angle grinders and their purpose
Angle grinder is a tool necessary for construction or repair work. It is convenient to use such a tool when the material needs to be cut, cleaned, polished. Of course, all this work can be done with the help of hand tools, but then you have to spend a lot of time.
"Bulgarian" is considered enough universal tool, with which you can perform various tasks:
- clean up welding seams;
- Cutting metal (for example, drainpipe);
- Grind various surfaces;
- Cutting concrete or stone (using a special abrasive wheel);
- Work with ceramic tiles.
Scope of application grinding machines wide, it will be difficult to list all the work done with its help at once.
Angle grinders are divided into two types according to their purpose: professional and household. Unlike household "grinders", professional machines can work in a more difficult mode, withstanding prolonged loads. True, such a tool is more expensive - more than quality materials. The electric motor of a professional angle grinder is able to operate almost continuously for several hours without overheating.
Differ angle grinders and in size. Large "grinders" allow you to use cutting wheels with a larger diameter, only a small disc can be installed on a small angle grinder. Each size of angle grinder has its own advantages when conducting certain works, and it will not always be convenient to use a large grinder. A large tool is convenient to use when you need:
- Make a deep cut (for example, cut a large diameter pipe);
- Cut through a thick layer of material;
- Handle solid material(concrete, stone).
Small "grinders" are convenient to perform various grinding and polishing work. First of all, the angle grinder was intended for this - it’s not for nothing that the name of the tool contains the word “grinding”.
Characteristics of the angle grinder
The main characteristics determine in what capacity it is best to use an angle grinder. Can be distinguished:
- Disc rotation speed (number of revolutions);
- Power;
- Functionality;
- Weight and size.
Rotational speed important in professional activity. With a low number of revolutions, it is impossible to carry out some work, or the processing will progress slowly. Some types of work need to be performed only at low disc speeds. Many inexpensive "grinders" have only one speed. As a rule, it is quite high (about 10-11 thousand rpm).

Power modern angle grinders range from 500 to 2800 watts. Headroom doesn't hurt, and usually more powerful is professional tool.
Weight and size are also of great importance for carrying out various works. It is not always convenient to use a large angle grinder, despite the high power of the tool. For example, when cleaning car body parts, it will be difficult to hold a bulky angle grinder for a long time, and in general it is inconvenient to use a large tool. And a small machine will not be able to make a deep cut, since it is impossible to install a cutting disc in it big size.
Functionality important for complex work requiring special conditions. TO additional features USM can be attributed to:
- The presence of speed control;
- Possibility of soft start;
- The presence of an additional handle;
- Extra vibration protection.
Cutting disc options
(circles) are defined by two main parameters:
- size,
- Purpose by type of material.
In total there are five main diameters of cutting wheels: 230, 180, 150, 125 and 115 mm, but professional discs may have a size of 300 mm or more. Accordingly, circles of a larger diameter are suitable for large angle grinders. More cutting discs have different thickness, and it can be from 1 to 4 mm.
Circles differ in their purpose - according to the type of material with which you will have to deal with when working. There are discs for metal, stone, wood, reinforced concrete. The circles themselves can be made from different material and have different shape.
Choosing an angle grinder for home use
For work at home, there is no need to buy a large angle grinder - just purchase a tool designed for installation cutting disc from 115 to 150 mm. Since, USM small size do not have very large power, then you should choose the most optimal model by this setting. best solution will purchase a machine with a consumption of 1000-1200 watts.
It is better to choose a tool model with a speed controller and a “soft” start - the angle grinder will start smoothly, and at different speeds it will be possible to process materials more efficiently. You should pay attention to the convenience of the handle. Not bad if the handle will have anti-vibration properties.
And another important factor is the choice of tool manufacturer. You should not buy an angle grinder of unknown origin - everyone knows that the miser pays twice. There are many popular brands that have proven themselves only with positive side. It is unlikely that it will be a disappointment to buy an angle grinder from Metabo, Bosch, Makita. And, of course, you should not buy a hand-held and used tool.
It may not cope with its task, for example, if it is necessary to make a curved cut. In this situation, an angle grinder (angle grinder) is used, as the grinder is correctly called. Let's consider in this article why the angle grinder got such a strange name, as well as its device and main areas of application.
Why Bulgarian got such a name
So, let's consider why the grinder is called the grinder. In general, calling it that way is incorrect. The term angle grinder is more suitable, which reveals the main essence of the design and use of this tool. The term "Bulgarian" is more familiar to our ear, because some self-taught masters do not always know correct name. This term came into use in our everyday life in the 70s of the last century. This is due to the fact that it was during this period that this instrument appeared in the Soviet Union, and it was released in Bulgaria. The name "Bulgarian" is shorter and more understandable to almost everyone, so it is unofficially more common.
Consideration of what can be done by a grinder
Firstly, the grinder is used where you need to cut something at an angle, for example, a pipe coming out of the wall. Also, with the help of it, you can saw through a strip in a sheet of material, where it can be quite difficult to wield with a conventional hacksaw.
Secondly, the grinder is used when grinding various surfaces. For this, special nozzles are used, which can be bought at any hardware store. It should be understood that the grinder is used for rough grinding of surfaces, since semicircular marks from the nozzle remain on it. Finer grinding is done using professional grinders.
Also on the grinder you can sharpen. Thus, it is possible to prepare the ends of the pipes before threading, or to correct them after cutting, so that the coupling or nut can be screwed on more easily.
Also, with the help of a grinder, it is made before laying it. At the same time, work must be done in a mask and goggles to protect against dust. Trimming is done using a special cutting wheel with diamond coating. It should be remembered that with the help of a grinder, you can make not only a straight cut, but also a curved one.
The main components of the grinder
At various manufacturers the device of the angle grinder may vary, so we will consider only its main components. This will allow you to understand what you should pay attention to when choosing this tool, as well as identify a malfunction in the event of a breakdown.
Main components:
- Bulgarian body. It is made of impact-resistant plastic and is designed to hold all the elements arranged in it in place. Also, with the help of the body, the operator's effort is transmitted to the equipment;
- reducer. It consists of gears, with the help of which the axis of rotation rotates 90 degrees. Also, gears allow you to reduce up to optimal amount revolutions;
- electric motor. It is located in the tool body and is designed to drive the drive gear of the gearbox, from which the torque is transmitted to the driven one. There is a disk on the axis of the large driven gear;
- electronics, which can be attributed various systems soft start, start buttons, maintain speed, etc.
Thus, we learned how the grinder is correctly called, and also for what purposes it is used and what main nodes it consists of.
What is the correct name for Bulgarian? Arriving at the store, you are unlikely to see such a name.
Name and brief description
Among the many terms that describe the tool, the most correct would be an angle grinder, or angle grinder. Most people consider metal cutting to be the primary function of an angle grinder. In fact, the grinder is also suitable for other abrasive work with metal, tile, stone, ceramics, wood. Huge selection nozzles allows you to perform a huge range of work with just one "grinder". What is worth one opportunity to sharpen tools and remove rust from metal products.
The invention of the "Bulgarian"
The construction of the world's first angle grinder began in Germany. In 1954, a tool appeared at one of the German factories, which we are so accustomed to calling "grinder". Grinding machines have come a long way to come to modern angle grinders. First there was a machine that operated with a foot pedal. He did not look a bit like a modern "Bulgarian" appearance but the functions were similar. By the twentieth century, a portable grinder appeared, vaguely resembling a huge ancestor. Next - the first manual grinding machine. Now its size was not so large, it became more convenient to work. And so, in the middle of the twentieth century, the first angular type machine appeared, familiar to almost all of us.
Modern models of angle grinders are significantly different from the first inventions. Angle grinders have enormous potential for innovation domestic manufacturer InterSkol. Every year, new features are invented that greatly facilitate the work with the tool and increase safety. There are brushes with self-shutdown, and speed controllers.
Name history
The name of the angle grinder "grinder" appeared not so long ago, in the 1970s. Then, in the USSR there were a lot of imported things from neighboring countries, since it was much cheaper to buy them than to produce them. Angle grinders, for the most part, were imported from Bulgaria. In addition, Bulgarian workers, coming to the USSR to work, brought this tool with them. In the common people, the term "angle grinder" switched to a simpler "grinder". So the instrument continues to be called today.
Lesser Known Titles
In addition to the "grinder", the instrument had several more interesting nicknames:
- "Fortune"
One of the first models of angle grinders that appeared on the territory of the USSR was called "Fortuna". She immediately gained immense fame because of her convenience and versatility. At the hearing of migrants who brought such grinders to the country, it was referred to only as "Fortuna". This is how the name stuck.
- "Monkey"
This nickname is little used in everyday life, it appeared thanks to a joke. There was a legend among the workers that hands were lengthened from working with such a tool. As a result, they become similar to the limbs of monkeys. The joke spread among people, and the angle grinder became a "monkey". So this humorous naming was fixed among the people.
- "Turbine"
Another humorous name. The fact is that angle grinders in the process of their work made a sound similar to the sound of an aircraft turbine. Walking past the factories where they worked as grinders, one might have thought that the workers were preparing the plane for takeoff. In the workshops of the Soviet space, the angle grinder became a "turbine". This name is not very popular, but you can still hear it.
- "Flexy"
This name is rarely heard in Russian-speaking countries, but in Europe, almost everyone will understand what kind of instrument you are talking about. This name appeared a very long time ago, around the 1930s. The first grinding tools began to be produced in Germany. Approximately in the 30s of the twentieth century, the MS-6-flexen model, a manual grinder, appeared there. The nickname "flexi" was assigned to this model of the instrument. With the advent of the first angle grinders in the 50s, the term was also applied to them. The model is gone, but the “nickname” remains.
It is surprising that the same instrument has many nicknames and names. The angle grinder owes its abundance of nicknames to the people. People from different cities can talk about the same instrument, but call it differently. Thanks to this article, you can avoid misunderstandings.
