What is the correct name for the nippers. Pliers and pliers - differences, characteristics and recommendations for choosing. General concept of a pliers tool

Two different names. But are they different instruments? I understood the nuances of terms and concepts website.

Word "pliers" is borrowed from French (such words are called gallicisms). And comes from a two-root word pince-a-tige.

Phonetic transcription - . That rare case when a French word entered the Russian language almost without distortion (only the “s” was doubled, apparently for elegance).

In its turn pince-a-tige consists of words:

• pince- clamp,
• tiger- rod.

It turns out that the literal translation from the French word "pliers" is a clamp for the rod.

By the way, some dictionaries indicate that pliers come from French words passe(pass) and tiger(kernel). But then the literal translation turns out to be illogical - "passage for the rod." Incredible theory.

If we turn to the Big Encyclopedic Polytechnic Dictionary, then the following meaning of the word is given there pliers:

manual metalwork and assembly and electrical installation tools, in which pliers and wire cutters are combined (in a hinge); two recesses with teeth are used for wrapping small pipes, connect. couplings, nipples, nuts, etc. (see fig.). One of the P. handles can end with a screwdriver blade, and the other with a square hole punch.

Origin of the word pliers

It's easy with pliers. The word is Russian, and it directly follows from it that this is an instrument with flat lips.

The Big Encyclopedic Polytechnic Dictionary provides the following definition of the word pliers:

manual metalwork and assembly tool with pyramid-shaped sponges and rectangular cross-section with notched vnutr. flat surfaces. They are used for gripping and bending small metal objects. details.

Pliers: design and purpose

Pliers have their own separate state standard - . According to this GOST, pliers are a tool designed to grip and clamp pipes and parts of various shapes.

To capture such cylindrical objects, the pliers have one or two recesses with serrated notches on the inner surface.

Below, in the photo, there are old Soviet pliers, they have such notches perfectly visible.

Pliers: design and purpose

Pliers are a simple and highly specialized tool. In accordance with the standard -, pliers are designed to grip and manipulate objects.

In strict accordance with GOST, corrugations must be applied to the inner surface of the sponges to at least half.

But formally, a tool with a completely smooth inner surface is also considered a full-fledged pliers.

Universal pliers

Over time, universal tools began to appear that combined much more functions than just gripping cylindrical objects. And here, manufacturers, without too tiring themselves with the accuracy of terminology, call such tools both pliers and pliers.

Here is an example where side cutters are added to the pliers for cutting wire and wires.

The most popular tool in the household are pliers. Although professional craftsmen also cannot do without this universal tool. Mechanics, locksmiths, electricians and other workers cannot do without them. With a large assortment of tools in the distribution network, there is probably no more necessary and universal thing.

Consider the existing types of pliers, their design features and differences from other similar tools, how to use them correctly, and how to make the right choice when purchasing.

Design features

Pliers refer to a pliers tool used for various electrical installation, plumbing and other work. Pliers can capture parts of various shapes, as well as thin pipes.

This product combines the design of two tools: wire cutters and pliers. This versatile device is very convenient when doing small household work by a home master. Pliers usually cut wires only from soft metal, since the cutting edges are deformed from hard material and quickly become unusable.

A special notch is applied to the jaws of the tool, the shape and size of which determines the reliability of holding the captured part. The notch also happens on the other side of the hinge axis, which is closer to the handles. This makes it possible to capture the part with any side of the pliers to choose from. The geometric shape of such a tool in different versions is almost the same, except for the dimensions. The longer the product, the greater the force on the jaws can be created. All other parameters and dimensions have minor differences.

Sharpening of the cutting parts plays a big role. When improving tools, manufacturers create various new qualities: they sharpen sharp edges at special angles, harden them in a special way, etc.

The assembly of a product largely determines its quality. Ideally, there should be no gaps and backlashes in the swivel joint, and the handles of the pliers should be moved apart with the fingers of one hand without much effort. A slight gap is allowed between the jaws in their compressed state (a few tenths of a millimeter).

Good quality pledge

In order to indirectly evaluate this tool for quality, it is enough to look at the end of the compressed jaws. If you see two equal rectangles of the correct shape, then most likely you are dealing with a quality tool. In the manufacture of this feature, almost no attention is paid, and the correctness of the forms of the sponges indicates the accuracy of the assembly. Well-known manufacturers of high-quality tools create an original hinge design that allows you to extend its life.

Metal

Steel for the manufacture of pliers determines their performance. When manufacturing at the factory, the composition of the material must be maintained, and a special heat treatment technology must be used to impart the necessary hardness and strength to the tool elements. In order for the swivel to serve for a long time, the hardness of the axis and the outer part must be equal. Cutting edges and sponges of expensive products, in addition to heat treatment, are usually additionally hardened with high-frequency currents.

Coating

Another important factor is the application of a special composition to the surface of the tool to prevent corrosion. Otherwise, after moisture gets on the instrument, they will quickly rust and become unusable. A simple coating is surface burnishing, which consists in placing the part in hot oil vapor, followed by coating with a protective varnish.

This treatment is also called oxidation. This is not enough quality protection when working with high humidity, so this tool is only used for indoor work. In order to be able to work without problems outdoors, a better finish, such as chrome plating, is needed. It imparts a beautiful steely sheen, especially if the finish is carefully polished.

Zinc coated pliers are quite rare. This coating is practically not inferior to the previous type, and in terms of resistance to mechanical shocks, it even surpasses it. However, in appearance, the zinc coating is clearly inferior.

handles

To ensure the convenience of working with pliers, the handles of the tool are enclosed in plastic. There are several types of handle insulation:

• Ordinary. They are made only of plastic that does not contain substances harmful to humans. They have a low cost.
• Ergonomic equipped with rubber pads. Rubber elements increase the convenience of work, however, with poor-quality rubber during contact with the palm, a person may experience an allergy.
• Electrical insulating, made of more rigid plastic for high-quality electrical insulation, ensuring the safety of the worker when working up to 1000 V.

An important factor is the reliable fixation of the overlays. On low-quality Chinese pliers, plastic handles can turn and slide off the tool, which greatly complicates their use. A simple way to attach plastic handles is to glue them. A more modern method of fixing is to fit the handles “hot”, that is, they are put on in a hot state, when they cool down, they shrink in temperature, and they are securely fixed on the instrument. In rare cases, handles are fastened with metal pins.

Kinds

There are several types of pliers, each designed to perform certain types of work.

Dielectric pliers

In terms of functionality and appearance, such a tool is similar to conventional combined pliers, but has special insulating handles for performing electrical work on connecting live electrical equipment, replacing metering devices (with permission and certain skills).

Soft handles of a convenient form allow you to safely and comfortably perform all the necessary work. The plastic of the handles can be reinforced with fiberglass for increased strength. The insulation material does not allow electric shock to a person. The surface of the handles is ribbed, which prevents the hands from slipping during operation. The jaws of the tool have special teeth to ensure a secure grip. The weight and overall dimensions of the tool are small, working with it for a long time does not create much fatigue.

grommet

This is a common tool for the home craftsman. In the manufacture of curtains and curtains, a plastic or metal ring with a diameter of up to 7 mm, which is called an eyelet, is often used. Thanks to specially designed pliers for eyelets, their installation is very fast. This procedure is greatly simplified: it is enough to apply a few forces on the handles, and the rings are completely fixed on the material.

Combined pliers

Such pliers can perform several functions of various plumbing fixtures and tools: side cutters, wire cutters, pliers, etc. They, like other models, are made of durable carbon steel, sharp edges are hardened to increase their service life. Metal elements are coated with a special coating and polished.

There are special versions of combined pliers that can even grip pipes, as they have the ability to adjust the size of the opening of the jaws. They are also called pipe or adjustable. They are also used to grip various large parts, thick cables, as a wrench.

Pliers

This is one of the varieties of pliers with flat jaws.

By the name of this tool, the shape of their sponges becomes clear. They are notched, there are handles and a swivel. Pliers are a handy tool for various electrical and plumbing work. Their flat jaws make it easy to hold parts of various shapes. Pliers usually bend the cores of wires, cables, as well as metal and steel wire.

The dimensions of the parts that can be clamped with pliers are determined by the dimensions of the tool itself (usually no more than 200 mm). Quite often, such a tool is used instead of a wrench, since flat jaws repeat the edges of the key. Of course, pliers cannot completely replace a wrench, but in extreme cases, when there is no necessary tool, they are quite justified.

There are some types of pliers that differ in the type of working sponges:

• Narrow long lips for work in hard-to-reach places.

• curved jaws, which also serve for hard-to-reach places, or during the installation of radio-electronic equipment.

• round nose pliers are mainly used for electrical work.

• "Platypuses". In fact, they are an analogue of tweezers, characterized by greater compressive strength.

• With various nozzles for the convenience of working with delicate and fragile materials.

To use pliers for live electrical installation, there are special insulated models. On plastic handles, the highest voltage value for which the insulation is designed is indicated. Most often, this value does not exceed 1000 volts. If this parameter is not specified, then the use of such a tool for working under voltage is strictly prohibited. Most likely, these are ordinary locksmith pliers, not designed to protect a person from electric shock.

Many people are mistaken in believing that pliers and pliers are one and the same. However, these tools have several differences:

• The shape of the surface of the jaws of the pliers is flat and does not have a notch.
• Compression force. By design, pliers are designed for high compressive force. Accordingly, steel for them is used more durable.
• The ability to adjust the amount of opening of the jaws is available only for pliers (by moving the hinge).
• Functionality. Pliers are less functional as they don't have side cutting edges.

• If you have enough money, it is better to purchase a professional tool model, as it is much better and more reliable in operation. If your purchase does not turn out to be a fake, then such a tool will last almost a lifetime.
• The play in the hinge indicates the low quality of the product, as well as biting and jamming when the jaws are moved apart. It is better to refuse such a tool.
• It is not allowed to move the plastic handles on the tool, especially if these are dielectric pliers.
• Gaps in closed jaws, and their uneven fit also indicate poor product quality.

Repair work requires the use of a variety of tools. The most popular are pliers and pliers. Many believe that these are names for one device. This fundamentally erroneous opinion is quite common, but has no substantive justification. Professionals, of course, know how they differ from each other, but not home craftsmen who take out a tool box only in case of emergency.

Both pliers and pliers are practical and versatile. They, unlike many other tools, cannot be replaced by other devices. The confusion between these devices arises from the external similarity, but the difference between them exists. It is quite weighty. Both tools are involved in electrical installation and repair work, but serve different purposes. The only similarity lies in the fact that both devices are pliers.

What are pliers and the scope of this tool?

The device is a metal lips with notches, united by a swivel joint, as well as handles. The latter are made from various materials. They can be plastic or wooden. The handles are designed in such a way that the tool is most comfortable to hold in your hand.

Pliers have a flat surface. Due to the design features, with this tool you can easily hold hardware and parts of various sizes. Pliers are used to deform cable, wiring and products made from sheet material.
The dimensions of fasteners and parts have their limitations. The tool can hold hardware and products with dimensions not exceeding 19.5 cm. This is quite enough to carry out a wide range of work without any problems. In addition, pliers are often used as a wrench to unscrew nuts.

Tool varieties

The difference between pliers and pliers is not only in design and purpose, but also in the fact that the latter are produced with different shapes of working surfaces:

• With long and narrow lips. A similar kind of pliers is used where the usual size tool simply does not fit through.
• With curved lips. It is used when performing electrical work, when it is necessary to "slip" the tool into a hard-to-reach place where simple sponges cannot simply crawl through.
• With removable jaws. This unusual variety is used quite rarely and is designed to perform manipulations with parts made of fragile materials.

Pliers resembling tweezers allow you to work with fragile and small items. Thanks to this shape, the parts are not deformed or damaged.

Insulated pliers

They are a tool that is used to work with conductive devices. On such pliers, the handles are insulated, but this does not mean that you can take any such device. The value of the operating voltage must be indicated on the tool. If there is no such mark, pliers cannot be used. Otherwise, there is a possibility that the insulation simply cannot withstand the applied voltage, and this creates a threat to life.

Features of choice

If you plan to work with hard-to-reach places, you should purchase a tool with narrow and elongated jaws. When the required part is located under any surface, pliers with a curved working surface are required. They allow you to get, for example, a part screwed to the board. Platypuses, that is, a tool similar to tweezers, are used in cases where delicate work is required. Similarly, pliers and silicone tips are used, which are worn over ordinary sponges.

Pliers: description and purpose

The multifunctional tool is a "relative" of pliers. Both devices have a similar appearance, as well as purpose. This is what misleads many home craftsmen that pliers and pliers are the same tool. A closer acquaintance with this device allows dispelling this myth.
On each side of the working surface of the pliers there is a notch on which there are notches. The latter allow you to capture and hold surfaces from a wide variety of materials. Pliers are widely used in plumbing and electrical work.
The combined surface of the tool makes pliers one of the most popular tools. Along with the notch, the working area also has a flat area. In addition, in many varieties of pliers there are two shallow, small indentations. They allow you to work with parts of various sizes.

Features and varieties of the tool

The hinges of the pliers are in special grooves. This allows you to adjust the force with which the lips are squeezed. The ability to reset the diameter does not complicate the work with the tool. Even someone who has never used such a device before will be able to carry out the “tuning”. To rearrange the diameter, it is necessary to spread the handles and reinstall the hinges in the recess.
The design of most varieties of pliers provides for the presence of side cutters. This accessory further expands the possibilities of using the tool. Side cutters can cut cables and wires, as well as quickly get rid of insulating cores. One of the working sides of the pliers has edges. They allow you to cut wire even from hard metals.
Pliers come in two varieties - locksmith and for use in the electrical field. The latter must have a marking that indicates the voltage for which they are designed.

The difference between pliers and pliers

To accurately find out the difference, you need to collect all the differences between pliers and pliers. They boil down to the following points:

1. The form. The working surface of each tool is different. For pliers, it is flat, and for pliers it has notches. Of course, there are also combined models of devices on sale, but they are extremely rare and used, since one workspace is usually only additional, and not fully functional.
2. Material. Pliers, unlike pliers, allow you to squeeze with much more force. To ensure a long service life of the tool, only high-strength steel is used for its manufacture. Pliers can be made from less durable metal without sacrificing functionality.
3. Additional features. Pliers are never with side cutters. Pliers, as a rule, are produced with this cutting device in their design.

Another feature that distinguishes pliers from pliers is that the former allow you to change the gap of the working area, that is, adjust the degree of compression of the part that is being manipulated.

How to choose a quality tool?

Pliers and pliers are two completely different devices, but the recommendations for a successful purchase for them are absolutely identical:

• The swivel type connection should be free of play, and the move should be smooth and soft. If it is impossible to close and open the handles without excessive effort, or, conversely, the sponges move completely freely, it is better to refuse to buy a tool.
• The handles also deserve special attention. They should be made not only of a convenient shape, but also of a material that does not slip. If the tool is planned to be used for electrical work, this part of the fixture necessarily involves insulation.
• When purchasing a tool, be sure to pay attention to how the working surfaces are in contact with each other. If any gaps remain, it will be almost impossible to work with such pliers or pliers.

Not the last role is played by the manufacturer and cost. If you plan to use the tool partly and to perform critical work, it is immediately recommended to purchase a professional model.

Pliers - this is the name of a tool belonging to the pliers type. With its help, various manipulations with objects are performed, and their scope extends from construction to medicine. For example, in dentists, teeth are removed with pliers. In everyday life and during repair work, such types of ticks as pliers and pliers are used.

The difference between them is not obvious to many. However, they differ not only in appearance, but also in their functional purpose. Each type of work requires certain devices.

Pliers

In almost any kind of locksmith work, these tools are used. All of them consist of a head, a handle and a movable axial joint.. Since ancient times, blacksmiths have used large tongs in their work, with the help of which they held the workpiece on the anvil.

Over time, society, craft and tools have changed. Simple ticks have been reborn into a range of multifunctional and useful devices. There were round-nose pliers, wire cutters, pliers and pliers.

Main features and differences

GOST defines pliers as a tool for clamping and gripping pipes, as well as parts of various shapes. In appearance, they are very similar to pliers. In addition to the working area, they have flat jaws, which are a continuation of the area for gripping pipes or bolts. Often this tool is equipped with side cutters for stripping insulation and cutting wire of small diameter.

Main differences:

• Pliers are a multifunctional tool, pliers are designed to perform one action.
• Pliers have flat working elements, with a notch along the entire length.
• The pliers have cutters for cutting thin wire and cavities for clamping tubes, and durable steel is used in their production.

Pliers allow you to solve more problems in the process of various household works. In many ways, they are able to replace end cutters, small household vise or side cutters, and capture almost any small object.

Pliers

Pliers are related to metalwork and assembly tools. With the help of sponges of rectangular section and pyramidal shape, they capture various objects or bend wire, metal parts.

Due to the low functionality for household work, this device is the least popular among tool buyers, who in most cases prefer pliers.

According to GOST, domestic-made pliers are available in two versions:

• with short jaws from 25 to 55 mm and long (from 50 to 63 mm);
• with simple handles and insulating, for work under high voltage.

The total length of the tool is in the range of 12–22 cm. In production, U7A tool steel is used with hardening up to 45 units. The finished product is subjected to anti-corrosion treatment in one of several ways.:

• chemical oxidation;
• chrome plating;
• chemical phosphate.

The color of the product directly depends on the processing method and can be black, matte gray or metallic.

In addition to standard samples, you can see on sale their other varieties, designed for a certain type of work. For example, "platypuses" are pliers with elongated jaws resembling tweezers. However, due to the powerful handles, they have a greater grip force. Or pliers with bent jaws - for working in hard-to-reach places.

pliers

If you take pliers and pliers in one hand, the difference between them will become obvious. The pliers stand out with a solid appearance due to a more powerful design and additional functions. They will more reliably hold almost any part, confidently capture the surface of a cylindrical shape, nuts, bolts or studs.

Some modifications may have grooved hemispherical recesses on the inside of the handles, which can be used as crimps.

For the production of this tool, chrome vanadium and chromium molybdenum steel are used, which makes it more durable than pliers. The handles are made of dielectrics, which allow working under voltage up to 1000 V. However, before starting such work, you must make sure that the pliers are marked accordingly.

The pliers of some models allow adjustment of the clamping force of the jaws. By rearranging a special hinge in the desired groove, you can increase or decrease the width of their disclosure. This is required to grip much larger parts than standard tools are capable of gripping.
