What is another name for pliers? Photo of the difference between pliers and pliers

The most common tool on the farm is pliers. They are universal and help in almost all types of construction and repair work. Often, pliers are used for purposes other than their intended purpose, for example, when unscrewing threaded connections. But a set of wrenches is not always at hand, but everyone probably has pliers. They are sometimes called pliers, although they are different pliers. Pliers are more specialized for installation work. Let's take a closer look at them.

Tool pliers

Although pliers are widely used, pliers were the first to be invented. This is a tool for grasping and holding small parts so that they can be used for work, for example, bending, biting, cleaning, etc.

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

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

pliers with elongated jaws;
with curved angles, for working in awkward places;
with their thin form;
pliers with short jaws for a strong grip;
with plastic linings for accurate clamping of the part;
modified edges to cut wire.

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

oxidation;
phosphating;
chrome plating

Pliers are produced both with and without handle insulators. In the first case, the tool is allowed to work with live electrical elements, which must be indicated on the insulators.

Pliers

The word "pliers" comes from the French language and is translated as "to clamp a rod." Therefore, the pliers tool has special oval or round recesses on the clamping edges for convenient gripping of tubular elements or cylindrical parts. They are usually of slightly different diameters. And the recesses must have a serrated notch.

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

In modern models, to grip parts of different diameters, not a set of recesses are used, but a complex design of the hinge connection, 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 chrome molybdenum steel. The degree of hardening reaches fifty-three, according to HRC.

Pliers equipped with plastic handles can be used in electrical installation work. To do this, they must be labeled with the number of volts they are designed for.

Pliers and pliers - the difference

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

Shape of working sponges. For pliers it is smooth, with small notches, and for pliers it has oval notches.
Size. Pliers (photos of them are presented in the article) are usually larger in appearance, have massive clamping jaws, and are often short.
The presence of an adjustable type swivel joint indicates that we are looking at pliers.
Multifunctionality is inherent in pliers, and narrow-nose application is inherent in pliers.
The steel grade, if indicated on the product, can also indicate the type of tool.

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

Electrical installation pliers

Universal insulated pliers have been developed specifically for electrical installation operations. With them you can do:

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

The permissible voltage with which such pliers can be used 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 typical 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 intended for working with electrical circuits, since it is technically impossible to equip them with insulating handles. The grade of steel from which this tool is made is not of high quality, so these pliers belong to a purely household class of products. The design of the instrument sometimes involves hiding the jaws themselves inside the body, and the kit may include a case for carrying in a bag or pocket.

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

How to use pliers

In order for pliers to serve for a long time, you must adhere to certain rules for working with them:

The tool must be lubricated.
Pliers are not designed to hold large objects, so they grab medium and small parts.
Gripping involves holding a product, for example, to guide a part and prevent it from slipping from a selected position. This is especially true if it is inconvenient to manipulate with your hands and your fingers are not strong enough to hold.
Capturing does not imply violent actions with the object. This may damage the tool and also damage the surface of the product.
Use pliers to grab the flat parts of the part.
When working with live parts, hold the tool only by the insulated handles. If possible, turn off the supply voltage before work.
Pliers are not designed for cutting through hard metals such as steel.
The most successful use of pliers is in radio installation work.

How to use pliers

Pliers can be used in more variety of ways, but certain rules must be followed:

It is not recommended to use rusty, unlubricated tools.
The distance between the handles should be sufficient to avoid pinching your fingers.
You can use pliers to hold flat and cylindrical parts. 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 cutting the wire, keep it perpendicular to the cutting edges.
When biting off the edge of the wire, you must ensure that it does not fly off and injure others.
Working with electricity is only allowed 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 using metalwork tools. If you choose the wrong pliers and pliers, the difference in the ease of working with them will be amazing.

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

These are hand tools that belong to the class of 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.

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 very limited or completely difficult, pliers with elongated (long) narrow jaws or jaws curved at different angles are used.

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.

There are pliers for performing plumbing work, there is a tool for which special attachments are used (especially relevant when working with fragile objects), and 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 the notches, of one or even two recesses of different sizes and sharpened 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.
Multifunctionality of some and narrow focus of others.
Manufacturers have different GOSTs and technical requirements for release.

Pliers and pliers belong to the pliers tools, another name for which is pliers. All of them are designed to manipulate objects, as well as to perform various operations, including tooth extraction. 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. What these items are and 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 metalworking and assembly tool equipped with pyramidal jaws of rectangular cross-section, used for gripping and bending small metal parts. From the definition it is clear that with pliers you can:

hold an object (metal strip, washer, nail, electrical wire);
bend a metal strip or 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 - the tool is now extremely rare in shop windows. 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 one type or another is not the length of the jaws, but the ratio of their linear dimensions to the dimensions of the clamping handles.
With plain or insulated handles. The latter are manufactured in accordance with GOST 11563-94, which regulates the requirements for hand tools for performing work under high voltage.

Dimensions of manufactured instruments: 125–220 mm (total length).

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

Chemical oxidation. The color of the coating is dark gray with a black tint.
Chemical phosphating. The surface of the instrument is matte gray, in 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 its humble relative, the pliers look more solid and are capable of more in their work. If you can only lightly grab the object being held with pliers, then pliers will clamp it much more securely. This works especially well when gripping cylindrical parts (rods, studs, bolts), thanks to the jaws, which are equipped with special recesses 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 (can serve as a crimp). The ends of the jaws are flat and equipped with the same notches as those of pliers. Sometimes pliers are equipped with additional corrugated elements made on the inside of the handles, next to the hinge, resulting in a second-class lever.

In the standard version, all pliers have cutting blades (side cutters) located next to the hinge, which can be used to cut thin metal strips and electrical wires. Wire and thin nails can be cut through two cutouts on one side of the tool, which work on the principle of a guillotine. In this case, the cutting force pinches the part in the grooves, making it possible to 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 their additional working functions, pliers are often called combination pliers. They usually have one (fixed) axis of rotation of the handles. There are designs with an adjustable hinge - two- or multi-position, which expands the clamping range of the tool.

Pliers are made from stronger steel than pliers. Typically chrome-molybdenum or chrome-vanadium steel is used. The gripping jaws are hardened to 53 HRC, and the edges of side cutters are hardened to 60 units.

A little about the handles. The amount of force applied depends on their shape and material. For this purpose, ergonomic pads are used to improve grip comfort. The material is rubber or a two-component coating (for example, thermoplastic rubber with santoprene linings). Dielectric handles (made of plastic) must have a confirmation inscription: work under voltage up to 1000 V.

So, pliers and pliers. The difference between them is in purpose and functionality. Let's look at the main distinguishing features of the two tools. The presence of at least one characteristic means belonging to one class or another.

Pliers are highly specialized, pliers are multifunctional metalworking tools;
The jaws of the pliers are flat, with a fine notch along the entire length;
Pliers have a shorter flat part of the jaws, and to grip cylindrical parts they are equipped with shaped (radial 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 an adjustable swivel joint;
Pliers are made from stronger and highly hardenable steel.

To summarize, pliers are a single tool, while pliers are multi-functional, replacing small hand vices, side cutters and end cutters. Buying pliers today is more appropriate. And most likely, everyone has pliers in their father's or grandfather's toolbox.

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 activities. 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’s worth taking a closer look at pliers and pliers, what the difference is 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 cone 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 required 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 transfer pressure, the structure has special handles, which can be made using various materials.

A good tool is produced by various companies that specialize in producing similar products. For the convenience of carrying out various works, the design is made 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 using insulating material are required. The manufacturer is required to write on the handles the maximum voltage that can be worked with. Information can be written using a variety of technologies; many will eliminate the possibility of overwriting during long-term use. If the maximum voltage is not specified, 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 craftsman 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 places.

Difference between pliers and pliers

All tools are designed to be used for a specific job. 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 provide the most comfortable conditions for performing 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 to the offers of only well-known manufacturers. This is due to the fact that they value their reputation and use only the highest quality materials, and also check all their 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.

Content:

There are many types of pliers. These include the familiar cutters, pliers, round nose pliers, as well as pliers and pliers. Each listed tool is designed for specific purposes and has its own dimensions and shape of the working surface. The design includes three main parts: a head in the form of jaws or cutters, an axial movable hinge and handles. However, they all have their own individual qualities. In this 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 installation work and operations with metal products. The working surface has a pyramidal shape, with notches applied on the inside of the flat jaws.

The design consists of two parts that are connected by the letter X and secured on a hinge that ensures their mobility. Each part consists of a working part that turns into a handle and forms a single whole with it. Thanks to the flat surface of the jaws, reliable gripping, bending, confident holding and twisting of wiring, as well as various parts made of wire and soft metals, becomes possible. In addition to its main purpose, pliers can be used as a wrench, the dimensions of which are limited by the expanding jaws.

Types of pliers:

A tool with narrow, elongated jaws has less compression force and is used when working with small parts.
Other plier designs have the jaws bent at a specific angle. This makes it possible to work with parts when access to them is significantly limited. This type of pliers is especially relevant for electronic devices where parts are hidden under circuit boards.
To work with live parts, there are special dielectric pliers. Insulated handles allow you to work freely in the presence of electric current. Their handles are marked indicating the permissible maximum voltage at which they 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 modernization, pliers turned into pliers and became a popular multifunctional tool. The pliers are equipped with small side cutters, two small cutters located on the sides. In the middle there is a round grooved hole through which small bolts and nuts can be tightened.

Installation and plumbing work cannot be done without pliers. They perform the functions of pliers and can perform many additional operations. Thanks to numerous accessories, 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 wire in a wide range of sizes and diameters. Some samples have the ends of the insulated handles with an awl and a screwdriver.

To perform installation and plumbing work, mainly dielectric and combined pliers are used. The first option refers to the one whose handles are insulated with special dielectric plastic. The second design is considered more universal, combining various tools. This allows you to perform many locksmith works 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 through metal wire.

Initially, only pliers were used for all work, for which there was no alternative. Gradually, they were modernized and improved to the technological level of pliers, which became a separate tool. Pliers can cut through almost any wire, while this ability of pliers is significantly limited. Pliers securely grip any part thanks to the existing recesses, but this is impossible to do with pliers. Before choosing one or another tool, you need to decide in advance on the list of work that will have to be performed.

Which tool to choose

The quality of 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 assortment of these products is offered, so the likelihood of error becomes quite high. It is advisable to collect all the necessary information about the desired tool in advance and only then 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 well-known manufacturers, rather than cheap Chinese goods. The surface of the material must be uniform in all places, and all parts must be equally strong. Pliers are usually coated with anti-corrosion materials. It is recommended to hold them in your hand in advance, trying on how comfortable they will be when doing the job.
