In the home workshop, there are always pliers and pliers, or, in extreme cases, one thing. This is a tool that is difficult to do without when performing virtually any type of work, both plumbing and electrical, mechanical, repair, etc.
Many consider pliers with pliers to be different names for the same tool, but this is absolutely not the case. They have different functions, moreover, in state standards they have different requirements.
Types of pliers
The first pliers tool can be considered blacksmith tongs, or perhaps a similar device, with which something was pulled out of the fire. The names of the authors of such a valuable invention, as well as its date, are hidden in the mists of time.
There are five main types of pliers. This:
- Ticks. They pull out nails, hold metal blanks.
- Wire cutters. This tool is designed, as the name suggests, to cut something, such as wire.
- Round nose pliers. Convenient for working with cable cores.
- Pliers. Clamping of any materials, bending, holding, etc. are used.
- Pliers. They are used for the same as pliers, plus they have many additional functions.
The classification is rather conditional, because, if desired, garden shears, scissors for cutting tin, etc. can be attributed to it. In addition, species necessarily have subspecies, and so on ad infinitum.
Pliers, their features and applications
To understand how pliers differ from pliers, it is enough to familiarize yourself with the structure of both. Pliers are pretty simple. As you might expect, this is a pair of flat lips, notches on them, handles and a hinge as a connection. It is convenient to work with wire, wire, sheet metal with such a tool, hold metal, wooden or plastic parts suitable for exchange, even tighten nuts if there is no wrench at hand.
Pliers come in different sizes, and most importantly, with different shaped lips. They can be elongated, narrow, curved in any direction. It all depends on the area of application. For example, pliers with curved or thin long lips are highly valued by radio engineers and electricians, since it is easy to get into hard-to-reach places with such a tool. Without electrical insulation on the handles, pliers are practically not produced. Usually, the insulating layer indicates how much voltage it can withstand.
Pliers: multitasking and versatility
Between pliers and pliers, the difference is fundamental in terms of functionality. Pliers are pliers plus side cutters, cutters for cutting wire or wires of various diameters, an additional grip placed after the swivel.
Side cutters can cut wires and wire, it is good to hold round objects of various diameters in the recesses, etc. There are modifications of pliers in which it is possible to adjust the compression force by moving the swivel rod into special grooves.
Several conclusions should be drawn from what has been written. If no one confuses wire cutters or pliers, then not everyone sees the difference between pliers and pliers. You just need to remember one thing - if the lips are only notched - these are pliers. If not only - pliers.

Pliers and pliers related to pliers can be found in any home. Each of us at least once used them at home or at work. They are used to work with various materials, in the repair of a variety of electrical equipment and machinery. But, despite their wide distribution and frequent use, rarely anyone calls these tools by their proper names.
pliers
pliers- a multifunctional hand tool used for plumbing and electrical work. With it, it is convenient to grab and clamp a variety of parts, regardless of their shape, including cylindrical ones. To capture and turn the latter on the jaws of the pliers, several recesses of various diameters were made with a notch applied to the entire working area. Pliers designed for electrical work are equipped with special insulated handles designed for use under voltage up to 1 thousand volts.
pliers
Universal pliers are also produced, combining the functions of pliers, side cutters and cutters for cutting wire of various diameters. For the manufacture of the tool, high-quality, which has undergone several treatments, is used. A special anti-corrosion coating is applied to the finished tool by chromium plating or oxidation.
Pliers
Pliers- a hand tool used for various plumbing and electrical work. Sponges have a pyramidal shape with a notch applied to flat inner surfaces. The working part of the tool, passing into the handles, moves with the help of a hinge. Pliers are used to grip, bend, and twist all sorts of small pieces of metal, wire, and wire. There are several types of pliers designed for different jobs. They differ in the length and width of the jaws. The pliers are also equipped with insulating handles for working under voltage.
Pliers Differences
At first glance, pliers and pliers look very similar. Both of them consist of a working area (sponges), handles and a hinge that provides movement. Both tools are designed to grip, hold and bend various parts. Of the differences, you can name the different shape of the sponges.
On the inner side of the pliers there are 1-2 pairs of grooves of different diameters with a notch, designed to hold cylindrical parts. The inner side of the pliers has a smooth flat surface with a notched finish that serves to better grip the parts to be held.
Pliers have the same width along the entire length of the jaws. Pliers, depending on their purpose, can have sponges of various lengths, widths and shapes (round-nose pliers, narrow-nose pliers, etc.). Pliers can be a multi-purpose tool that combines the functions of pliers, side cutter and cutter. Pliers are used for any specific action.
Findings site
- Pliers are a multifunctional carpentry and assembly tool, and pliers are narrow-profile.
- The inner surface of the pliers has several cylindrical grooves of different diameters; the pliers have a flat surface.
- The jaws of the pliers are of standard width, and the jaws of the pliers, depending on the purpose, have a different shape and width.
- The non-fixed hinge of the pliers allows you to change the gap of the jaws, and the gap of the jaws of the pliers does not change.
The difference between pliers and pliers is a fact beyond doubt.
Pliers and pliers have some differences.
Common features of tools and design features of pliers
These are hand tools that belong to the class of pliers. Outwardly similar to each other, pliers and pliers often cause confusion, especially among ignorant people. Their construction is simple. These are two metal sponges that perform the main working functions (clamp, hold, bite, etc.), with handles, connected by a hinged mechanism. They have the same simple principle of operation: it is based on the same actions - closing and opening the jaws. The reduced handles provide compression of the sponges, divorced - their unclenching.
The described tools are rightfully considered the most popular. And this statement applies to both professionals and amateurs. Electricians, locksmiths, mechanics, electronics engineers - this is not a complete list of specialists in need of them. And there is no need to talk about domestic orientation.
Pliers are a multifaceted, multifunctional tool. At the same time, when working, they can act as wire cutters and side cutters, pincers and pliers. Some of them are additionally equipped with a screwdriver and an awl located at the ends of the handles. The working area of sponges is equipped with notches. There can also be up to two recesses of different circles at once, the main purpose of which is to capture and hold parts of a round, cylindrical or other shape. The outer side on the sponges is endowed with sharp edges (edges), with which you can bite nails or wire.
And pliers equipped with dielectric handles marked “1000V” are used for electrical work.
There are pliers, where an additional work area is defined under the swivel joint. This means that you can also grab objects with the handles.
On some models, it is possible to adjust the compression force of the jaws, as well as the distance between their faces by occupying a certain position of the hinge in special grooves.
Pliers are made from high quality steel, the processing of which takes place in several stages. And a special anti-corrosion coating is applied to the surface of the finished tool by oxidation or chromium plating.

The variety of pliers, their narrow specialization, differences between tools
Pliers are deprived of everything that is present in pliers. There are no recesses, pointed edges on the lips. Their hinge is fixed.
But there are many of them, and they are designed for different tasks. Only for each operation you have to individually select a certain type.
The main differences are in the width, length and shape of the working jaws. So, when working in places where access is very limited or even difficult to implement, pliers with elongated (long) narrow or curved jaws are used.
There are "platypuses" that provide great compressive strength, required where precise work is especially needed.
And when performing electrical work, you need a tool, the handles of which must be insulated with an indication of the maximum allowable voltage on them.
There are pliers for plumbing work, there is a tool for which special nozzles are used (especially relevant when working with fragile objects), universal pliers are widely used.
However, with all the similarities, there are significant differences between pliers and pliers. Here are the main ones:
- The size (length, width) of the working jaws. For some, their width is standard, the same along the entire length, for others, due to the specificity of the task, the appearance, length and width are completely different.
- The shape of the working surface of the sponges. The presence on its inner part, in addition to notches, of one or even two notches of different sizes and pointed edges for pliers and a completely flat working surface (notches do not count) for pliers.
- Not fixed, and therefore adjustable hinge (pliers) and its rigid fastening (pliers).
- Compression force. For pliers, it is higher, which is achieved by stronger steel.
- The versatility of some and the narrow focus of others.
- Different GOSTs and technical requirements from manufacturers upon release.
Two different names. But are they different instruments? I understood the nuances of terms and concepts site.
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 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.
