What are pliers for? What is the difference between pliers and pliers?

Pliers and pliers are among the most popular tools. This is true for both professionals and home DIYers. They are irreplaceable for electricians, mechanics and many other specialists. And how to manage without them in everyday life is simply incomprehensible to the mind. With all the diversity of the tool market, it is difficult to imagine a more universal and necessary thing.

But why do we say they? Is there a difference between pliers and pliers? There are also quite a few. It just so happens that no one really differentiates between them. This is not surprising since they are very similar in appearance. But, nevertheless, there are differences that are quite significant. These differences are taken into account not only by users, but also by manufacturers. For each of them their own technical requirements in production and their own GOSTs. What is the difference between pliers and pliers? What types of work are they intended for? How to determine the quality of this tool? This will be discussed in the article.

Articulated pliers tool, its types

The history of the creation of this type of tool, and it belongs to the pliers tools, goes back to at least the era greek gods. Humanity has been familiar with blacksmith's pliers since time immemorial. Time passed, human society changed, and the instrument also changed. No one knows when exactly and in whose head the idea to create a prototype of modern pliers arose. It's a pity. The thing turned out to be very necessary and practical.

There are many varieties of articulated pliers tools. These include:

mites;
pliers;
wire cutters;
round nose pliers;
pliers.

Each category has “subspecies” that have different sizes of the working surface (sponges), purpose and shape. For example, round nose pliers (shown in the photo below) are very convenient for cutting cable cores. The conical shape of the working surface allows you to comfortably bend cable cores under clamps of different diameters. There are models that are additionally equipped with wire cutters. To work with delicate materials, special attachments made of plastic or other material are used. The presence of notches on the pliers allows you to securely fix the part while soldering boards, and the special shape of the jaws allows you to get into the most inaccessible places of the microcircuits (the angle of the jaws can be different).

The same goes for wire cutters. Different shape cutting part, its different size, different purposes. For example, wire cutters for repairing electronic equipment are smaller. They are not suitable for cutting cables, no matter what purpose. Theoretically, this is possible, but both the worker and the tool will suffer. In the worst case scenario, you may be left without wire cutters.

Types of pliers. Features and scope

Already from the name one can see the characteristic appearance of this tool: flat knurled jaws, swivel joint and handles. Pliers are indispensable during any plumbing or electrical installation work Oh. Thanks to the flat surface, they hold parts of any shape well. Using pliers you can bend cable strands, wires, wire and metal. The dimensions of the parts are determined by the dimensions of the pliers themselves (usually do not exceed 200 mm). It is very common to use this tool as a wrench for unscrewing/tightening nuts of various diameters. This is still somewhat unusual work for them, but what can you do when you don’t have a key of the required diameter?

Pliers are divided not only by size. For user convenience, manufacturers produce different types working surface:

elongated narrow jaws - for the ability to work in places with limited access;
angled jaws are designed for working in hard-to-reach places, especially in electronics;
so-called “platypuses”, in fact this is a type of tweezers, but with a greater compression force;
with special attachments for working with fragile and delicate materials.

To work in electrical installations or with live parts of equipment, special pliers with insulated handles are required. On these handles mandatory The maximum voltage that the insulation can withstand must be specified. In the majority household tools this value is up to 1000V. If this characteristic is not indicated on the pliers, it is strictly prohibited to use them in live networks. This means that you are dealing with a metalworking tool and the manufacturer simply does not provide protection for the user from electric current.

There are many types of pliers; their type is selected individually, depending on the tasks at hand.

Pliers - practical multifunctionality

Since pliers are “relatives” of pliers, their purpose is similar. They are widely used for plumbing, electrical installation and other types of work. The working surface of the pliers has a recess with notches. It is designed to grip and securely hold round and smooth surfaces. As a rule, pliers have a combined jaw surface, i.e. In addition to a special recess for round parts, there is a flat part working area. And in some modifications there are two recesses for different diameters of the part.

Some models of pliers allow you to adjust the compression force of the jaws; for this purpose, several options are provided for the location of the hinge in special grooves. The rearrangement process is quite simple: open the handles and rearrange them into the required recess. In addition to the degree of compression, this also allows you to adjust the distance between the edges of the jaws, i.e. expands the range of sizes of captured parts.

In most cases, pliers are equipped with side cutters. They allow you to remove core insulation and cut wire or cable cores. In addition, they may have special edges on front side sponges for cutting wire of hard metals.

Some manufacturers expand the working area of the pliers by making notches on the handles immediately behind the hinge joint. This allows you to grip the part not only with jaws. How necessary and convenient this is, we will leave it to the users to judge...

Pliers are also divided into electrical and metalworking pliers. Firstly, dielectric handles must be marked up to 1000V.

Pliers and pliers - the difference

It's time to sum it up. So what are the differences between pliers and pliers? There are three main ones:

The shape of the working surface of pliers is flat, without a recess. Although they meet combined types tool with notches on pliers. But this is the exception rather than the rule. In addition, the pliers are structurally designed for greater compression force. What does it mean? This means that the manufacturer selects the appropriate grade of steel for the pliers, which has greater strength;

The ability to adjust the gap of the working surface of the jaws and the degree of force of the tool is provided only for pliers (this is achieved by rearranging the hinge);

The versatility inherent in pliers is not typical for pliers, i.e. As a rule, there are no side cutters or special edges for cutting wire (again, these possibilities depend on the grade of steel and hardening).

If your financial capabilities allow, buy professional pliers and pliers. This is not a whim, the difference between amateur instrument and professional, even leading brands, very significant. When choosing a power tool, you can save on professional equipment. It's not critical there. And in manual it is very even. It’s just a shame when, in the midst of work, you suddenly find yourself without pliers, or after 10 pieces of wire have been bitten off, it becomes impossible to use side cutters. The joy from such acquisitions will disappear very soon. The same cannot be said about professional hand tools. If it's not a fake, then if used at home it will last a lifetime.
Pay attention to the hinge, there should be no play there. The ride should be soft and smooth. This is a sign of a quality instrument.
When the jaws of the cutters or pliers are closed, there should be no gaps, the surfaces should touch evenly, this is the key to high-quality production and assembly.
The handles must fit securely on the handles; free sliding, etc., is not allowed. Especially for power tools.

There are simply a huge number of different hand tools that can be used when carrying out work. The most common are pliers. They are used in everyday life and in organizing professional activity. A fairly common question is what is the difference between pliers and pliers. All craftsmen take these differences into account when choosing hand tools. It is worth taking a closer look at pliers and pliers, what is the difference between these designs and other points.

Pliers tool

Humanity has been familiar with blacksmith's pliers for many centuries. It is not yet known exactly when the instrument in question was made. There are different types of pliers:

Ticks.
Classic design.
Round nose plier.
Pliers.
Wire cutters.

Moreover, each group has several of its own subcategories, which have their own form and purpose. For example, core processing can be done correctly by using round nose pliers. The curved conical shape of the working surface allows you to conveniently bend the end of the cable.

Types and uses of pliers

The most common type of such tools are pliers. The right tool has the following design features:

The jaws are flat and have serrations. However, the sizes of the sponges may vary significantly.
The cutters are connected using a hinged design.
To transmit pressure, the design has special handles that can be made when used various materials.

A good tool is produced various companies, which specialize in the production of such products. For convenience various works The design is available in several versions. There may be significant differences between them. The following versions of pliers are widely used:

It is worth considering that to work with various electrical equipment or conductive products, special pliers with handles made during the application are required insulating material. The manufacturer is required to write on the handles the maximum voltage that can be worked with. Information can be written when using the most various technologies, many will eliminate the possibility of rubbing during long-term use. If maximum voltage is not indicated, then using the tool is strictly prohibited.

There are two main groups of pliers:

Classification is also carried out according to the size of the product. A master who often uses the tool in question may have several options for pliers in his kit: the larger the size, the greater the force that can be transmitted; smaller models are suitable for working in hard to reach place.

Difference between pliers and pliers

All instruments are intended for use when conducting certain work. The differences between pliers and pliers are as follows:

Considering how pliers differ from pliers, it is worth noting that the first version is multifunctional, the other is suitable for carrying out a small amount of work.

Correctly choosing the most suitable tool should be in order to ensure the most comfortable conditions to carry out work. The fact that a structure can consist of several elements determines the difficulties that arise when choosing. The best option can be selected taking into account the following information:

It is recommended to pay attention exclusively to the offer famous manufacturers. This is due to the fact that they value their reputation and use only the most quality materials, and also checks all manufactured products.

Adjustment of transmitted force

On sale you can find products that allow you to adjust the compression forces. Such models can be used in cases where the workpiece being processed should not be subjected to mechanical stress.

In any repair work popular tools are both pliers and pliers. For some, such a statement may be confusing, because some are sure that the tools listed above are one and have no difference and the difference is that it has two names. This opinion, for unknown reasons, is quite widespread, but this myth needs to be dispelled, which is what we will do in this article.

The tools in question are used by both masters of their craft and ordinary home craftsmen who take out a box of tools only when absolutely necessary. Mechanics, electricians, and plumbers cannot imagine their workday without the use of pliers and pliers.

As a result, we can conclude that the tools in question are universal and very practical, and if necessary, replacing them with another tool will not work. Today we will have to understand the topic - what is the difference between pliers and pliers.

There are quite significant differences between these instruments, and they are confused because they are very similar in appearance to each other. Not only users can feel these differences, but also manufacturers who are engaged in the assembly line production of such parts.

Their main common similarity is that pliers and pliers belong to the articulated pliers type of tools.

Types of pliers. Features and scope

The name of this tool, like pliers, immediately gives an idea of its appearance: metal lips that have notches on their surface, a hinge-type connection and a handle (can be made of various materials, including plastic and wood).

The flat surface of the tool makes it possible to easily and without problems hold parts of any size. The multifunctional tool can be used for a variety of purposes: deforming wiring, cables, metal parts. The parameters of the parts that can be worked with pliers must correspond to the capabilities of the tool itself and its size (usually no more than 195 mm).

Among other things, pliers can also be used instead wrench, because it is very simple to unscrew various types of nuts with a tool, despite the fact that this is not their main purpose.

Pliers and pliers can differ not only in parameters (width, length, etc.), but also in their working surface:

Pliers with fairly narrow and long jaws. This tool is very convenient to use where other tools cannot fit.
Tools with curved jaws are used in the electronics industry. It is with this tool that you can get into places where analog tools cannot “go.”
Pliers, unlike pliers, look like tweezers, and are perfect for working with small and very fragile parts. A properly designed form makes it possible to firmly hold such parts without causing deformation to them.
There are also tools with removable jaws for making various actions with parts made of fragile material.

It is also necessary to remember that when working with conductive devices, it is imperative to use pliers with insulated handles. If the tool does not indicate the voltage value with which it can work, it is prohibited to use them in the electrical industry. It is necessary to choose the type of pliers taking into account immediate task which is presented to them.

What are pliers, features of the tool

Without exaggeration, this tool can be called practical and, moreover, multifunctional. They are a close relative of pliers, not only in appearance, but also in purpose, so you need to find out the difference between pliers and pliers.

The tool in question has become widespread in the electrical installation industry and plumbing. On the working surface of the pliers there is a notch with notches, the main purpose of which is the ability to capture and hold various types of surfaces.

The surface of the jaws of the pliers in question is combined and that is why the range of its use is so wide. Apart from the notch, part of the working area of the pliers is a flat surface. Some types of tools also have a couple of small and shallow recesses so that you can simultaneously work with different sizes details.

Among other things, to important features pliers also include the ability to regulate the force of lip compression (for such purposes, the hinges are located in special grooves). Switching from one diameter to another is very simple, and anyone, even a beginner, can handle this action - the handles are moved apart and the hinges are moved into the selected recess).

Most types of this tool have side cutters in their design, which make it possible to quickly and safely remove insulation from the cores and cut cable cores, and wire can also be cut. On one side of the tool there are edges for cutting wire from solid type metal

There are several types of pliers - for plumbing and for the electrical industry. The latter must be provided with an inscription indicating what voltage they are designed for.

What is the difference between pliers and pliers?

Despite detailed description features of the analyzed tools, which are similar to each other, not everyone may have understood what is their difference and what to use. To answer this question. Here are a few specific distinctive characteristics instruments considered:

First of all, they differ in the shape of the working surface; if in pliers these are recesses, then in pliers - flat surface. Despite the fact that today you can find various types of instruments, including combined models, such examples are extremely rare.
Pliers have the ability to compress with great force, therefore the steel used for their manufacture is more durable.
The following feature applies exclusively to pliers - it is possible to regulate the surface gap itself, as well as the degree of compression of the part.
There are no side cutters on the surface of the pliers, unlike pliers.

Now knowing the differences in these tools, you can purchase exactly the tool that you will use. Don't spare money, don't skimp, and the best option will be the acquisition of high-quality professional products.

The difference between pliers and pliers is a fact that is beyond doubt.

Pliers and pliers have some differences.

General features of tools and design features of pliers

This hand tools, which belong to the class of articulated pliers. Externally similar to each other, pliers and pliers often cause confusion, especially among ignorant people. Their design is simple. These are two metal jaws that perform basic operating functions (clamping, holding, biting, etc.), with handles connected by a hinge mechanism. Their operating principle is just as simple: it is based on the same actions - closing and opening the jaws. The closed handles ensure the compression of the jaws, and the separated handles ensure their unclenching.

The described tools are rightfully considered the most popular. Moreover, this statement applies to both professionals and amateurs. Electricians, mechanics, mechanics, electronics engineers - this is not a complete list of specialists in need. And there’s no need to talk about the household focus.

Pliers are multifaceted, multifunctional tool. At the same time, when working, they can act as nippers and side cutters, pliers 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 the 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. External side The jaws are equipped with sharp edges, which can be used to cut through nails or wire.

And pliers equipped with dielectric handles marked “1000V” are used for electrical installation work.

There are pliers where an additional working area is defined under the hinge joint. This means that you can also grab objects using the handles.

Some models provide for adjusting the compression force of the jaws, as well as the distance between their edges by occupying a certain position of the hinge in special grooves.

The 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 using oxidation or chrome plating.

The variety of pliers, their narrow specialization, differences between tools

Pliers are devoid of everything that is present in pliers. There are no grooves or sharp edges on the jaws. 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 the width, length and shape of the working jaws. Thus, when working in places where access is severely limited or completely difficult, pliers with elongated (long) narrow or curved nose pliers are used. different angles sponges.

There are “duckbills” that provide greater compression force, required where precise work is especially needed.

And when performing electrical installation work, you need a tool whose handles must be insulated with the maximum permissible voltage indicated on them.

Pliers are included to perform plumbing work, there is a tool for which special attachments are used (especially relevant when working with fragile objects), universal pliers are widely used.

However, despite all the similarities, there are differences between pliers and pliers, and significant ones. Here are the main ones:

Size (length, width) of 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 jaws. The presence on its inner part, in addition to notches, of one or even two recesses of different sizes and pointed edges of pliers and completely smooth working surface(notches do not count) on 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.
Multifunctionality of some and narrow focus of others.
Manufacturers have different GOSTs and technical requirements for release.

Pliers and pliers are common and sought-after tools both at home and among professional craftsmen.

Meanwhile, many people confuse pliers with pliers, not seeing much difference in them. Below we explain the difference between pliers and pliers and which of these tools is the most popular and versatile.

Pliers by type

Pliers vary in their purposes:

with short jaws for a strong and firm grip
with extended jaws
with narrow (or thin) lips
with curved ones - when working in hard-to-reach places
with internal plastic linings to avoid damaging parts
specialized, for working with wire

The working (inner) surface of the jaws is smooth or with small shallow notches - for better grip of the object. “Jaws” is the part of the tool that grips parts.

Differences between pliers and pliers

Pliers are locksmith tool, similar in appearance to pliers. Some versions - which can no longer be confused with pliers - use an adjustable hinge mechanism. The jaws of standard pliers are usually shorter than the jaws of pliers.

The name “pliers” is French, literally meaning “to clamp the rod.” And in order to clamp it tightly, on the inside of the edges, which are always corrugated - with notches, there is an oval or round depression, often two.

Pliers are a more serious tool

Pliers, unlike pliers, are intended for more serious work. Therefore, in terms of strength, the requirements for them are high. If the hardening level of the pliers does not exceed 45 units, then the pliers are hardened to the level of 53 units. And the cutting parts - side cutters and cutters - are hardened to a level of 60 units.

Their metal is good too

More High Quality and the metal from which the pliers are made. If used for the production of pliers carbon steel of a certain brand, then chromium is used in combination with molybdenum or vanadium to produce pliers.

Dimensions according to GOST

The sizes of pliers vary. There are “miniature” categories – for thin and precision work, for example, bench modeling or beadwork - 10 centimeters.

The dimensions of tools for installation, plumbing, automotive and other work are specified in GOST 17 438-72. For pliers of the first group, he defines the length as 160, 180 and 200 mm.

The second group, intended for industrial work, fits into three types of lengths - 200, 250 and 300 mm.

Imported products, made in the EU, USA and China, come in sizes 10; 11.5 and 14 cm.

What types of pliers are there?

Different types of pliers are used in production and everyday life:

Universal
Dielectric
Combined
Extended
*Adjustable, sometimes called tubular
For eyelets

If you compare photos of pliers of all the listed types, the differences are immediately obvious. Their main functions and purposes are listed below.

Pliers for all occasions

Universal pliers, or as they are also called - metalworking pliers, are often incorrectly called pliers. After the finely corrugated jaws, they always have a serrated notch. It is followed by side cutters - for cutting the wire, and next to the hinge there are cutters for cutting through stronger wire, nails and even chain-link mesh.

For work under voltage

Dielectric pliers are intended for electrical work. They are available with insulated handles, usually rubber or a combination of rubber and various types dielectric plastic.

The mains voltage is divided into two types - in everyday life 220 V. In production, the same 220 V and an additional 380 V. To avoid trouble, the insulating handles of the pliers can protect against shock voltages of 1000 V.

Please note: this parameter must be indicated on the pliers themselves, and not on its packaging. Since we are talking about human life, it is better to buy dielectric pliers from trusted manufacturers.

Pliers for eyelets

Eyelets, plastic or metal, are intended for strengthening holes in shoe, leather goods and other industries and workshops.

In view of this, “eyelet” pliers are a highly specialized and highly professional tool. They differ from other pliers in their specific appearance and are easily recognizable.

The longest pliers

Extended pliers feature long jaws. In some versions, the length of the sponges reaches 20 centimeters. Outwardly, they resemble tweezers with pliers handles attached to them. They are designed to work in narrow cracks or openings.

Based on the principle of a penknife

This type is directly opposite to the highly specialized “eyelet” ones. It is called “combined pliers”. This tool is intended for various household jobs. But professionals also use them as universal ones - for all occasions. But in this case the tool must be from quality manufacturer, otherwise it quickly fails.

Combination pliers are made on the principle of a penknife or Swiss knife and are equipped with a lot of functions and capabilities.

Typically, combination pliers are only part of a multifunctional set, which includes a number of necessary tools, for example, screwdrivers with bits.

Pliers for plumbers

Plumbing pliers are the largest among pliers. They are used exclusively for plumbing work. To capture gas or water pipes large diameter The design of these tools uses an adjustable hinge mechanism. Thanks to this, you can change - increase or decrease the diameter of the gear recess.
