Large pliers. What is the difference between pliers and pliers? There are some varieties of pliers that differ in the type of working sponges

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, the characteristic appearance of this tool is “visible”: flat jaws with notches, 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 a 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 of work 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, the maximum voltage that the insulation can withstand must be indicated without fail. 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 for different diameters of the part.

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 expand the working area of the pliers by making notches on the handles just 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).

If financial opportunities allow, buy professional pliers and pliers. This is not a whim, the difference between an amateur instrument and a professional instrument, even from leading brands, is 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.
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 instrument.
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.
The handles on the handles must sit securely, free sliding, etc. is not allowed. Especially for power tools.

Content:

There are many varieties of pliers. These include the familiar wire cutters, pliers, round nose pliers, as well as pliers and pliers. Each listed tool is designed for specific purposes, has its own size and shape of the working surface. The design includes three main parts: a head in the form of sponges or incisors, an axial movable hinge and handles. However, they all differ in their own individual qualities. In the article, we will look at the difference between pliers and pliers.

Pliers: purpose and design features

Pliers belong to the category of hand tools used in electrical work and operations with metal products. The working surface has a pyramidal shape, notches are applied on the inside of the flat sponges.

The design consists of two parts that are connected by the letter X and are fixed on a hinge that ensures their mobility. Each detail consists of a working part, passing into the handle and making up a single whole with it. Thanks to the flat surface of the jaws, it becomes possible to securely grip, bend, confidently hold and twist wiring, as well as various parts made of wire and soft metals. In addition to their main purpose, pliers can be used as a wrench, the dimensions of which are limited by retractable jaws.

Types of pliers:

A tool whose narrow jaws are elongated has less compressive force and is used in working with small parts.
In other designs of pliers, the jaws are bent at a certain angle. This makes it possible to work with details when access to them is significantly limited. This type of pliers is especially relevant for electronic devices, where parts are hidden under the boards.
To work with live parts, there are special dielectric pliers. The isolated handles allow to work freely in the presence of electric current. Their handles are marked with an indication of the permissible maximum voltage at which you can work.

Pliers - a universal tool

The basis of pliers are pliers, which appeared much earlier and were intended to perform the simplest functions. As a result of upgrades, pliers have turned into pliers and have become a sought-after multifunctional tool. Pliers are equipped with small side cutters, two small cutters located on the sides. In the middle there is a round corrugated hole through which small bolts and nuts can be screwed.

Assembly and locksmith work is not complete without pliers. They perform the functions of pliers and can perform many additional operations. Thanks to numerous devices, pliers successfully work with various parts, regardless of their configuration. Thus, pliers acquired the universal qualities of many tools at once. They became simultaneously pliers, side cutters and cutters capable of cutting the wire of the widest range of sizes and diameters. For some samples, the ends of the insulated handles with an awl and a screwdriver.

For installation and plumbing work, mainly dielectric and combined pliers are used. The first option refers to, the handles of which are insulated with a special dielectric plastic. The second design is considered more versatile, combining various tools. This allows you to perform a lot of plumbing work of the widest range and focus.

What is the difference between pliers and pliers

Based on the previous description of each tool, we can conclude that the main difference between pliers and pliers is their versatility. This is due to the fact that pliers have only one function - gripping, and only some models can cut metal wire.

Initially, only pliers were used for all work, to which there was no alternative. Gradually, they were modernized and improved to the technological level of pliers, which stood out as a separate tool. Pliers can bite through almost any wire, while pliers have a significantly limited ability to do so. Pliers reliably capture any part, thanks to the recesses, and this cannot be done with pliers. Before choosing one or another tool, it is necessary to determine in advance the list of those works that will have to be performed.

Which tool to choose

The quality of the work performed with its participation depends on how correctly the tool is chosen. Therefore, despite the fact that pliers have significant differences from pliers, the choice of each of them must be approached responsibly.

Pliers require more attention when choosing due to the large number of different functions. Currently, a large range of these products is offered, so the probability of error becomes quite high. It is advisable to collect all the necessary information about the desired tool in advance and only after that go shopping.

First of all, you need to pay attention to the material from which the pliers or pliers are made. It is best to purchase a product from reputable manufacturers, rather than cheap Chinese products. The surface of the material must be uniform in all places, and all parts must be equally strong. Pliers are usually covered with anti-corrosion materials. It is recommended to hold them in your hand in advance, trying on how comfortable they will be when doing work.

Pliers and pliers are multifunctional working tools belonging to the group of pliers. Pliers and pliers are used in plumbing, electrical work, and in repairing mechanisms and devices.

Often, pliers and pliers are considered the same type of tool, but this is wrong, since although these useful devices belong to the same group of tools, they differ in design, characteristics, and functional purpose. What is the difference between pliers and pliers, how to choose a quality tool - topics that will be discussed in detail in the article.

What is a pliers tool?

To fully understand the difference between pliers and pliers, you should understand what a pliers tool is in general. This group of tools includes a wide variety of useful devices that facilitate the work of the wizard. Pliers can be called:

Ticks;
wire cutters;
round nose pliers;
pliers;
Pliers.

These are the main categories and in each of them there are separate types of devices that will differ from each other in the size of the working surfaces - “sponges”, shape and functionality. For example, round-nose pliers are most convenient to use when working with wires and cables, and wire cutters are indispensable in repairing and setting up electrical equipment.

Round-nose pliers are most convenient to use when working with wires and cables

It should be understood that the listed tools can be interchangeable, but this is inconvenient and moreover - using the device for other purposes, it can be damaged or completely broken. Therefore, it is so important to understand the difference between pliers and pliers, and to know what kind of work uses a certain type of tool.

Description and characteristics of pliers

Pliers have a special shape, as the name of the tool itself speaks quite eloquently: the device is equipped with flat notched jaws. The design of the pliers is simple: they consist of two elements connected in the form of the letter X. The working part goes into the handles and moves due to the hinge. A tool is used to perform plumbing, electrical work, and is involved in the repair of some mechanisms. Using pliers, you can achieve a strong fixation of parts, bend the cable or metal as needed, less often the tool can be used to tighten or loosen nuts.

A versatile tool for almost any task

There are different types and sizes of pliers, and the scope of the tool will depend on these parameters.

Types of pliers

The classification of the tool is carried out according to the type of working surface:

Devices with elongated jaws are used to perform work in a narrow and cramped space.
For electrical work, models with an elongated and curved jaw shape at a certain angle are more often used.
Pliers-"platypuses" are used as tweezers: its sponges have a maximum length and are strongly extended forward. Another key advantage of the model is the increased compression force.
In work with fragile materials, pliers are used, the working surface of which either does not have notches or is additionally equipped with a softening coating. For this type of tool, you can additionally buy soft silicone tips.
There are also combined models that have a special recess on the working surface that allows you to securely hold round parts. Pliers are also available with a cutting edge.
Sliding models will help you firmly capture hexagonal, round or square parts. The jaws of such pliers have a strong bend, and the tool itself is larger in size than models of other types.
Side pliers are easy to distinguish from other types by the cutter on one side of the jaws. A tool is used for cutting elements from different materials: wire, plastic, sheet metal, cardboard.

When purchasing side-type pliers, specify to work with what materials the model is intended, since using a tool for copper and cardboard on materials that are more rigid and durable is easy to ruin the tool.

Pliers with a semicircular shape of the jaws are used when working with wires. The working surface of the tool may or may not have cutting edges. If edges are present, pliers can be used to cut the wire material. The shape of the jaws of the tool allows you to capture uneven surfaces, and therefore this type of pliers is in demand in plumbing and repair work.

A separate type of tool are dielectric models with insulating handles, which allows the use of pliers in work under voltage. The permissible operating voltage must be indicated on the tool handle. Usually its value is 1000 volts.

What is the difference between pliers?

Having dealt with the design, purpose and types of pliers, it is worth finding out - what are pliers and what is the difference between these very similar tools?

The key difference between pliers and pliers is that the latter type of tool has a notched notch on its working surface, which allows you to hold the parts as firmly as possible during work. The jaws of the pliers are most often of a combined shape, and their extreme part is made in the form of pliers. Some models of the tool have not one, but two recesses with different sizes, which is convenient, since it becomes possible to fix and hold elements of various shapes and sizes.

The key difference is the shape of the sponges

On sale you can find pliers with a movable hinge element in the grooves. By moving the hinge, you can adjust the compression force as needed, as well as the size of the opening of the jaws. The considered variety of pliers is considered universal: it is applicable in working with parts of different sizes.

Most models of devices are equipped with side cutters, which are used to strip the insulation from the cable, some pliers have special edges for cutting hard wire. The tool is used in plumbing, electrical work, therefore, on their handle, the voltage value at which it is safe to use pliers is mandatory.

Having studied the design and types of pliers, we can conclude that the tool will differ from pliers in the following properties and characteristics:

Pliers have a flat working surface, without notches;
The design of the pliers gives the maximum possible compression force, so the tool is produced from higher quality steel alloys;
Using pliers, you can adjust both the compression force and the size of the gap between the jaws.

Pliers are more functional, since the tool has side cutters, and in some cases edges, these elements allow you to use the tools in different types of work.

In order to choose high-quality and reliable pliers, when buying a tool, it is recommended to pay attention to the following parameters:

The size of the gap between the jaws. It should be no more than one 1 millimeter, and the handles of the tool should be interconnected as tightly as possible;
The handles of a good tool should move easily and smoothly;
It is worth evaluating the cutting edges of the device - their gap should not be more than 0.1 mm;
To perform electrical work, electrically insulated models should be purchased;
The handle of the tool should be comfortable, close to the anatomical shape of the hands.

You can ignore the material of the decorative coating of the tool, as it does not affect the functionality and quality of the pliers.

If the budget is not limited, then it is better not to save money, but to purchase a professional tool made from better materials and using modern technologies. Professional pliers will not break and will serve you as long as possible.

We hope this detailed article helped you understand the difference between pliers and pliers, learn useful details about the existing types of pliers, and find out the parameters for choosing high-quality pliers.

Pliers and pliers belong to pliers, another name for which is pincers. All of them are designed to manipulate objects, as well as to perform various operations, up to the extraction of teeth. Moreover, even dental pliers are diverse. The situation is similar with such household tools as pliers and pliers, the difference between which exists, although not obvious to everyone. About what these items are, for what purposes they are used - will be discussed in this article.

Pliers

This instrument comes from our childhood. A large encyclopedic dictionary of technical terms defines pliers as a hand-held metalwork and assembly tool equipped with rectangular-section pyramidal sponges used to grip and bend small metal parts. From the definition it can be seen that with pliers you can:

hold an object (metal strip, washer, nail, electric wire);
bend a metal strip, wire.

That is, their main purpose is capture and manipulation. The tool can only hold and bend. It is not for nothing that among its many relatives - pliers - it is now extremely rare in the windows of tool stores. Domestic pliers must comply with GOST 7336-93, according to which they are:

With short (25–55 mm) or long (50–63 mm) jaws. By the way, the criterion for belonging to a particular type is not the length of the jaws, but the ratio of their linear dimensions to the dimensions of the clamping handles.
With plain or insulating handles. The latter are manufactured in accordance with GOST 11563-94, which regulates the requirements for hand tools for performing work under high voltage.

Available instrument sizes: 125–220 mm (total length).

Domestic tools are made from U7A carbon tool steel with volumetric hardening up to 45 HRC units. A decorative coating for corrosion protection is applied in one of 3 ways:

chemical oxidation. Color of a covering - dark gray with black outflow.
chemical phosphating. The surface of the instrument is matte gray, of various tones (from light to dark gray).
Chrome plating. This coating is the most durable and corrosion resistant.

Pliers. Everything is captured

If you put pliers and pliers next to each other, the difference will become noticeable. Next to their modest relative, pliers look more solid, and they are capable of more in work. If the pliers can only lightly grab the object being held, then the pliers will clamp it much more securely. This is especially good when gripping cylindrical parts (bars, studs, bolts), thanks to the jaws, which are equipped with special grooves with a large notch. Some models have two pairs of grooved grooves of different depths, and sometimes they make an additional semicircular groove located on the side of the handles (it can perform the crimping function). At the end, the sponges are made flat, equipped with the same notches as those of the pliers. Sometimes pliers are supplied with additional corrugated elements made on the inside of the handles, next to the hinge, a lever of the second kind is obtained.

As standard, all pliers have cutting blades (side cutters) located next to the hinge, which can be used to cut thin metal strips, electrical wires. Wire and thin nails can be cut with two cutouts on one side of the tool, which work on the principle of a guillotine. At the same time, the cutting force pinches the part in the grooves, so that you can squeeze the handles with both hands. The force increases even more due to the increased ratio of the lever arms - the cutting grooves are located close to the axis of rotation. Due to the additional working functions, pliers are often called combination pliers. Usually they have one (fixed) axis of rotation of the handles. There are designs with an adjustable joint - two- or multi-position, which expands the clamping range of the tool.

Pliers are made of stronger steel than pliers. Usually chrome molybdenum or chrome vanadium steel is used. The gripping jaws are hardened up to 53 HRC, and the edges of the side cutters are hardened up to 60 HRC. A little about handles. The amount of force applied depends on their shape and material. For this purpose, ergonomic pads are used to increase the comfort of the grip. The material is rubber or a two-component coating (eg thermoplastic rubber with santoprene linings). Dielectric handles (made of plastic) must have a confirmation inscription: work under voltage up to 1000 V.

Find 6 differences

So, pliers and pliers. The difference between them is in purpose and functionality. Consider the main distinguishing features of the two tools. The presence of at least one sign means belonging to a particular class.

Pliers - highly specialized, pliers - a multifunctional bench tool;
The jaws of the pliers are flat, with a fine notch along the entire length;
For pliers, the flat part of the jaws is shorter, and to capture cylindrical parts, they are equipped with figured (radius or triangular) notches with a large notch;
Pliers have cutting edges (nippers or side cutters), as well as transverse cutters for cutting wire or nails;
Can be equipped with a reversible swivel joint;
Pliers are made of stronger and highly hardened steel.

Summing up, we can say that pliers are a single tool, and pliers are multifunctional, replacing a small hand vise, side cutter and end cutters. Buying pliers today is more appropriate. And pliers, most likely, will be found in everyone in their father's or grandfather's tool.

Multifunctional tools can be found in any home. Pliers and pliers are indispensable in plumbing, when repairing triples and mechanisms, during electrical work. Some mistakenly believe that these tools are no different from each other. In fact, they belong to the same group, but differ in purpose and cannot be interchanged.

Plier Features

If you need to repair an object with metal parts or carry out construction work, then use pliers. The working part resembles a pyramid in shape, the sponges are flat, hence the name. On the inside there are special notches. Two metal parts of the pliers are connected crosswise. Under the working part there are handles that are set in motion thanks to the hinge. The smooth surface allows bending, clamping and fixing products made of soft metal alloy, wires, metal sheets. Sometimes pliers are used to loosen nuts, but this does not apply to the main functions.

The tool may have a different appearance. Pliers are divided into 6 types, each of which is designed for specific manipulations.

With an elongated and narrow working surface. The tool has a low compression force. Used for small parts made of soft metal alloy.
With curved ends. Helps to work with hard-to-reach parts. Excellent electronics pliers, allow you to get to the elements under the boards.
With thin and elongated ends. Most often used for fixing small nails. The handles help increase grip strength when needed.
For work with details from delicate materials. The working part is distinguished by a softened or smooth coating. May have silicone overlays. They are used when working with materials that can break or scratch with inaccurate exposure.
Combined can be made in two versions. The first subspecies is distinguished by the presence of a notch on the working surface. The second subspecies has a sharp edge. Combination pliers will help when you need to grab a rounded tube or bite off a piece of thin wire.
Dielectric pliers. They differ in the presence of insulation on the handles. Used when working with electricity. Please note that the handles indicate at what maximum voltage it can be used.

Remember that pliers are used to capture medium and small parts, large ones will not work. Remember to periodically lubricate moving parts. Certain rules of work will help to increase the life of the tool.

The grip helps hold the part in position so it doesn't slip. You can guide the product with pliers. The function is in demand in cases where it is not physically possible to perform the task with the hands, or the strength of the fingers is simply not enough.
It is not necessary to perform violent actions while capturing an object. Rough handling can damage the tool itself or damage the surface of the part.
Classic pliers allow you to grip only flat parts. For rounded ones, use a combined look.
When working with electricity, hold the tool by the handles only. If possible, turn off the voltage before starting manipulations.
Pliers can only cut through soft metals. Do not use for biting off parts of steel parts: this will damage the tool.
The functionality of pliers is most in demand in radio installation work.

What are pliers?

Prevent corrosion on the metal, always lubricate the work surface. This will help increase the life of the pliers. In addition, there are some rules of use.

Pay attention to the distance between the handles so as not to pinch your fingers.
Pliers make it possible to capture flat and cylindrical parts.
Can be used to hold nuts. It is better not to unscrew the tightened nuts with the help of pliers.
It is important not to push, but to pull the tool when working.
If you need to bite the wire, then install it perpendicular to the cutting part.
When working with electricity, hold the tool by the handles made of insulating material.

What is the difference?

According to GOST, pliers and pliers are hand-held bench and assembly tools. Visually, they are quite easy to distinguish by essential features.

The size. Pliers have short and massive sponges, large handles. The instrument is smaller.
The difference in the shape of the working area. Pliers are distinguished by oval notches, while pliers have smooth jaws.
Only pliers are equipped with a swivel joint.
Pliers are more versatile, and pliers are narrow-profile.
Work with flat parts with pliers. If you need to grab a round or cylindrical one - with pliers.
Pliers have a more curly surface, so the grip will be more reliable.
