What does the pliers tool look like? What is the difference between pliers and pliers

One of the most common tools are pliers and pliers, but not everyone knows what their difference is, so let's try to figure it out. These tools are used by both professionals and home craftsmen. Locksmiths, electricians, mechanics and other specialists cannot do without them. AT household often there is a need for different kind work, during which it is almost impossible to do without these devices.

Many people believe that these are the names of the same tool, but they are wrong, since pliers and pliers are different from each other. Although outwardly they have similarities, but in the production of each of them, their own technical requirements and they have different GOSTs.

Types of pliers

This type appeared a very long time ago and is constantly being improved, new types of it appear.

Round-nose pliers are used when soldering microcircuits.

Varieties of pliers:

• pliers;
• round nose pliers;
• ticks;
• pliers;
• wire cutters.

In addition, each species also has its own subspecies, which differ in the size and shape of the sponges. Each model has its own purpose. For example, to bend a cable of different diameters, a device with cone-shaped jaws is used. For convenience, wire cutters can be additionally installed on such models.

If it is necessary to work with plastic or other fragile parts, special nozzles are used. Special notches are made on the round-nose pliers, which helps to more reliably fix parts with their help, and the fact that they have such a sponge shape allows you to work in hard-to-reach places, for example, when soldering microcircuits or carrying out other work.

Nippers can have different sizes and shapes of the cutting part. For work with a thick cable, more powerful wire cutters are used, they are not suitable for working with radio components, small wire cutters are needed here.

Plier Features

The name itself indicates the shape of this device; pliers have flat jaws, on which notches are made. The tool is used when performing various plumbing, electrical and other types of work. With it, you can simply and securely hold parts, bend cables, metal, the tool is often used instead of a wrench to unscrew or tighten nuts.

In addition to the difference in size, the pliers differ in the type of working surface:

• elongated jaws are used to work in confined spaces;
• in electrical engineering, elongated jaws are often used, curved at a certain angle;
• there are tools in the form of tweezers with flat lips, the so-called "platypuses";
• for work with fragile materials use special nozzles.

When performing electrical work, there is a great danger of electric shock, therefore, devices used when working with electrical tools and wires must have specially insulated handles on which the manufacturer indicates the maximum voltage that they can withstand.

Most often, for domestic use, a device with protection up to 1000V is used. If the pliers have rubber handles, but the voltage value is not indicated, then they are not intended for electrical work - they can only perform plumbing work.

Features of pliers

They are direct relatives of pliers, so their scope will be similar.

On the working surface of the pliers there must be a recess with notches.

Its presence allows you to securely hold the parts.

Sponges usually have a combined shape, and their edge is made in the form of pliers.

Some models of recesses can have two different sizes, which allows you to hold parts of different shapes and sizes.

There are models in which the hinge can move in the grooves, so it is possible to adjust the compression force and the amount of opening of the jaws, which allows you to work with pliers with parts of different sizes.

Most of these devices have side cutters with which you can remove the insulation from the cable, there can also be special edges that allow you to cut hard wire. Pliers are available for plumbing and electrical work, so the voltage at which to work must be indicated on the handles of the latter them safe.

The main differences between pliers and pliers

Having considered the device and the purpose of these devices, we can highlight their main differences:

1. The shape of the working surface of the pliers is flat and does not have a special recess.
2. With the help of pliers, you can create much greater forces, so they are made from higher quality steel.
3. Pliers have the ability to adjust the degree of compression and gap of the jaws, while pliers do not.
4. Pliers are more versatile, they have side cutters, a device for cutting wire, which pliers do not have.

How to buy a quality tool?

Joinery and carpentry tools: a, b - wire cutters, c - tongs, d, e - pliers.

It is best to purchase a professional tool, but keep in mind that its cost will be more expensive than that which is intended for everyday use. The professional tool has best quality, it is more reliable, if you bought not a fake, it will last you a lifetime, it will serve reliably and always do its job with high quality.

One of the main features of a quality model is a hinge, which should not have any play, its movement should be easy and smooth. Another sign of quality professional tool is the absence of a gap with closed jaws of pliers or pliers. The surface must be flat and they must be adjacent to each other throughout the plane.

When choosing a power tool, pay attention to the quality of the insulation on the handle. It should sit tightly, in no case should it move, it must necessarily indicate the value of the maximum voltage at which you can work with such pliers or pliers.

As you can see, there is no big difference between pliers and pliers, both are used to perform similar work, but there are still some differences. In the household it is necessary to have both, then you can independently, without outside help do all housework.

Pliers, pliers, pliers, wire cutters are representatives of a very diverse group of tools called pliers. Their main difference is in the shape of the working surface, determined by their purpose. These tools are actively used in various fields, they are used by dentists, blacksmiths, and railway workers. In particular, pincers are one of the most ancient tools; they are an integral attribute (along with the hammer) of the Greek god of fire - Hephaestus. Let's start with ticks.

Ticks

Railroad workers have tongs for carrying railway sleepers, as well as for carrying rails.

Tongs for carrying sleepers and rail (ROBEL)

Carpentry (carpentry) tongs pull out nails.

Joiner's (carpenter's) tongs (GEDORE)

Plumbing tongs (pipe) usually have a serrated recess for gripping pipes, inclined jaws and an adjustable hinge mechanism for clamping pipes of different diameters.

Sanitary pliers (STAYER)

The pliers also include a number of electrical installation tools: these are crimp pliers for terminals, pliers for stripping wires, pliers for connectors, pliers for cable glands, current pliers, insulating pliers for replacing fuses, etc.

In general, almost any pliers can be called pincers, for example, pliers, in a simplified way, these are pincers with flat jaws.

Combination pliers, sometimes referred to as pliers, are a tool that includes pliers, has cutting edges for cutting wire and nails, a notch with teeth for gripping pipes, nuts and various cylindrical parts. This is a multifunctional tool, on the one hand, able to help in various situations, on the other hand, special tools cope with specific tasks better. Therefore, combination pliers are a tool for a household tool kit, and not for a professional one.

Antique pliers with two notched notches,
for large and small diameters

Modern pliers, instead of several notches, have an adjustable hinge for pipes of different sizes.

Adjustable joint pliers (Task Force)

Apparently, pliers differ from plumbing pliers in a smaller size, or you can safely put an equal sign between them.

What many are accustomed to calling pliers, according to GOST 5547-93, are combined pliers. And it turns out that on the one hand, this tool can be defined as pliers with pliers, and on the other hand, pliers with pliers.

wire cutters

When buying wire cutters, pay attention to what kind of material they are intended for cutting, as copper wire cutters may not be able to cope with nails, and the cutting edges will be damaged.

Wire cutters for cutting cables, ropes, fittings, bolts have a special solid construction, increased hardness of the cutting edges, often several hinges to provide increased compressive strength.

The most common tool in the household are pliers. They are universal and help in almost all types of work during construction and repair. Often, pliers are used not quite for their intended purpose, for example, unscrewing threaded connections with them. But a set of wrenches is not always at hand, and everyone probably has pliers. They are sometimes called pliers, although they are different pliers. Pliers are more specialized under installation work. Let's look at them in more detail.

Tool pliers

Despite the fact that pliers are widespread, pliers were the first to be invented. It is a tool for gripping and holding small parts so that work can be done with them, such as bending, biting, stripping, and the like.

If we consider pliers and pliers, the difference is obvious. The word "flat" itself implies the presence of sponges on the tool, the working part of which has a flat surface. In some models, they are stuffed with a special fine notch for better fixation of parts during their processing.

There are several modifications of pliers, the difference between which lies in the shape of the sponges. To perform various functions, the following have been developed:

• pliers with elongated jaws;
• with bent at an angle, for work in inconvenient places;
• with their subtle form;
• pliers with short jaws for a firm grip;
• with plastic overlays for accurate clamping of the part;
• edge-modified to cut wire.

The material from which the pliers are made is U7A carbon steel. In addition, the metal is subjected to a volume hardening of forty-five units and coated protective layer with help:

• oxidation;
• phosphating;
• chrome plating.

Pliers are available with or without handle insulators. In the first case, the tool is allowed to work with electrical elements, under voltage, which must correspond to the inscription on the insulators.

pliers

The word "pliers" came from French and translates as "clamp the rod." Therefore, the pliers tool has special oval or round recesses on the clamping edges for easy gripping of tubular elements or cylindrical parts. They are usually several different diameters. And the recesses must have a serrated notch.

Sometimes pliers can be confused with combination pliers. But the latter, along with an oval recess, have a cutting edge, and sometimes in the area of ​​​​swivel on different planes of the tool there is also a sample for cutting hard metal wire.

In modern models, not a set of recesses is used to capture parts of various diameters, but complex structure hinge joints, where the latter can move apart, thereby increasing the distance between the jaws. These are more functional pliers (the photo demonstrates this perfectly).

Structurally, pliers are a more powerful tool than pliers. They are made from high-strength chrome-vanadium and chromium-molybdenum steel. The degree of hardening reaches fifty-three, according to HRC.

Pliers equipped with plastic handles can be used in electrical work. To do this, they must be affixed with an inscription on how many volts they are designed for.

Pliers and pliers - the difference

There are several signs by which it is easy to distinguish pliers from pliers:

1. Form of working sponges. For pliers, it is even, with small notches, and for pliers - with oval selections.
2. The size. Pliers (their photo is presented in the article) are usually larger in appearance, have massive clamping jaws, often short.
3. The presence of a rotary hinge of an adjustable type indicates that we have pliers in front of us.
4. Multifunctionality is inherent in pliers, and the narrow focus of application is inherent in pliers.
5. The steel grade, if it is indicated on the product, can also tell the type of tool.

Holding pliers and pliers in front of you, everyone can see the difference.

Wiring pliers

Especially for electrical installation operations, universal insulated pliers have been developed. With them, you can do:

• Fixing round and flat parts.
• Bending wires and twisting copper wire.
• Cutting copper cable, the thickness of which does not exceed 15 mm.
• Removal of electrical insulation.
• Crimping cable lugs.
• Stripping the wire from oxides.

The permissible voltage with which you can work with such pliers should not exceed 1000 V, which is indicated on the handles of the tool.

Multifunctional pliers

This type of product is more of a survival tool than a normal construction and repair tool. This is evidenced by the presence of many functional elements included in the kit. This is a set of knives, a screwdriver, a corkscrew and, of course, pliers. All this is folded into the handles of the latter, according to the principle of a penknife.

Multifunctional pliers are not designed to work with electrical circuits, since it is technically impossible to equip them with insulating handles. The grade of steel from which this tool is made does not differ high quality, therefore, such pliers belong to a purely household class of products. The design of the tool sometimes involves hiding the sponges themselves inside the body, and the kit can come with a case for carrying in a bag or pocket.

Pliers 200 mm (multifunctional) have a jaw length of 2 centimeters, cutting edges for wire and a selection for cylindrical parts, like pliers. Their handles are equipped with rubber or two-component insulators.

How to work with pliers

In order for the pliers to serve for a long time, it is necessary to adhere to certain rules for working with them:

• The tool must be lubricated.
• Pliers are not designed to hold large items, so they will grip medium to small items.
• The grip involves holding the product, for example, to guide the part, to prevent it from slipping from the selected position. This is especially true if it is inconvenient to manipulate with the hands and the strength of the fingers is not enough to hold.
• Capture does not involve violent actions with the subject. This can damage the instrument and also damage the surface of the product.
• Pliers produce a grip on the flat parts of the part.
• When working with live parts, the tool is held only by insulated handles. If possible, turn off the power supply before work.
• Pliers are not designed to cut through hard metals such as steel.
• The most successful use of pliers in radio work.

How to work with pliers

Pliers can be used in a more diverse way at work, but certain rules must be observed:

• It is not recommended to use a rusty, unlubricated tool.
• The distance between the handles should be sufficient so as not to pinch your fingers.
• You can hold flat and cylindrical parts with pliers. You can hold the nuts, but it is not recommended to unscrew tightened nuts with pliers.
• When working, the pliers do not push, but pull.
• When biting the wire, it is held perpendicular to the cutting edges.
• When biting off the edge of the wire, it is necessary to ensure that it does not fly off and injure others.
• Work with electricity is allowed only with pliers with insulated handles.

Conclusion

Despite the apparent simplicity of the tool, when working with pliers and pliers, it is necessary to adhere to all safety rules for the operation of a metalwork tool. If you choose the wrong pliers and pliers, the difference in the convenience of working with them will be amazing.

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

But why do we say they? Is there a difference between pliers and pliers? There is also a lot. It so happened that no one really makes a difference between them. This is not surprising since they are very similar in appearance. But, nevertheless, there are differences and very significant. These differences are taken into account not only by users, but also by manufacturers. Each of them has its own technical requirements for production and its own GOSTs. What is the difference between pliers and pliers? What kind of work are they for? How to determine the quality of this tool? This will be discussed in the article.

Hinged - pliers tool, its types

The history of the creation of this type of instrument, and it belongs to the pliers, goes back to the era of at least the Greek gods. Mankind has known blacksmith's tongs since time immemorial. Time passed, human society changed, and the instrument changed. When exactly and in whose head the idea to create a prototype of modern pliers arose, no one knows. It's a pity. The thing turned out to be very necessary and practical.

There are many varieties of pliers and pliers. These include:

• ticks;
• 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 are very convenient for cutting cable cores (shown in the photo below). The conical shape of the working surface allows you to comfortably bend the cable core under the clamp of different diameters. There are models that are additionally equipped with wire cutters. To work with delicate materials, special nozzles made of plastic or other material are used. The presence of notches on the round-nose pliers allows you to securely fix the part during board soldering, and the special shape of the jaws allows you to get into the most inaccessible places of the microcircuits (the angle of inclination of the jaws can be different).

The same applies to nippers. Different shape of the cutting part, its different size, different purpose. For example, wire cutters for repairing electronic equipment are smaller. For cutting cables, no matter what purpose, they are not suitable. Theoretically, this is possible, but both the worker and the tool are tormented. In the worst case, you can be left without wire cutters.

Types of pliers. Features and scope

Already from the name "visible" characteristic appearance This tool includes knurled flat jaws, swivel and handles. Pliers are indispensable during any plumbing or electrical work. Due to the flat surface, they hold a part of any shape well. With the help of pliers, you can bend cable cores, wiring, 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 wrench, for loosening/tightening nuts of various diameters. This is still somewhat unusual work for them, but what to do when there is no key of the required diameter?

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

• elongated narrow jaws - for the ability to work in places with limited access;
• jaws curved at an angle are designed to work in hard-to-reach places, especially in electronics;
• the so-called "platypus", in fact it is a kind of tweezers, but with a large compression force;
• with special nozzles, for work with fragile and delicate materials.

For work in electrical installations or with conductive parts of equipment, special pliers with insulated handles are required. On these handles without fail the maximum voltage that the insulation can withstand must be specified. In most household tools, this value is up to 1000V. If this characteristic is not indicated on the pliers, it is strictly forbidden to work with them in energized networks. This means that you are dealing with a bench tool and the manufacturer simply does not provide protection for the user from electric current.

There are many varieties of pliers, their type is selected individually, depending on the tasks.

Pliers - practical versatility

Since pliers are "relatives" of pliers, their purpose is similar. They are widely used for plumbing, electrical 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 surface of the jaws, i.e. in addition to a special recess for round parts, there is a part of a flat working area. And in some modifications there are two recesses under different diameter details.

Some models of pliers allow you to adjust the compression force of the jaws, for this there are several options for the location of the hinge in special grooves. The rearrangement process is quite simple, spread the handles and rearrange into the desired recess. In addition to the degree of compression, this also allows you to adjust the distance between the faces of the jaws, i.e. expands the size range of gripped parts.

In most cases, pliers are equipped with side cutters. They allow you to strip the insulation of the cores and cut the wire or cable cores. In addition, they can have special edges on the front side of the jaws for cutting hard metal wire.

Some manufacturers are expanding working area pliers, making notches on the handles immediately behind the swivel. This allows you to capture the part not only with sponges. How necessary and convenient we will leave it to the users' judgment ...

Pliers are also divided into electrical and locksmith. In the first, dielectric handles must be marked up to 1000V.

Pliers and pliers - the difference

It's time to sum it up. So what's the difference between pliers and pliers? Main three:

The shape of the working surface, for pliers it is flat, without a notch. Although there are combined types of tools with notches on the pliers. But this is more the exception than the rule. In addition, pliers are structurally designed for greater compression force. What does it mean? This means that the manufacturer selects the appropriate steel grade for 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);

For pliers, the multifunctionality inherent in pliers is not typical, i.e. the presence of side cutters, special edges for cutting wire, as a rule, is not (again, these possibilities depend on the steel grade and hardening).

1. If financial opportunities allow, buy professional pliers and pliers. This is not a whim, the difference between an amateur instrument and a professional one, even the leading trademarks, very significant. When choosing a power tool, you can save on professional equipment. It's not critical. And in manual very even. It's just a shame when, in the midst of work, you are suddenly left without pliers or after 10 bitten pieces of wire, it will be impossible to use side cutters. The joy of such acquisitions will soon disappear. What can not be said about a professional hand tool. If not a fake, then when used in everyday life, it will last a lifetime.
2. Pay attention to the hinge, there should not be any backlash. The move should be soft and smooth. This is a sign of a quality tool.
3. With closed jaws of nippers or pliers, there should be no gaps, the surfaces should touch evenly, this is a guarantee of high-quality production and assembly.
4. The handles on the handles must sit securely, free sliding, etc. is not allowed. Especially for power tools.

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

it hand tools, which 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.

Back to index

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:

1. 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.
2. 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.
3. Not fixed, and therefore adjustable hinge (pliers) and its rigid fastening (pliers).
4. Compression force. For pliers, it is higher, which is achieved by stronger steel.
5. The versatility of some and the narrow focus of others.
6. Different GOSTs and technical requirements from manufacturers upon release.
