What pliers are the best. Pliers. Types and device. Work and features. How to choose. Additional features of pliers

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 covered with a protective layer using:

  • 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 parts. cylindrical shape. There are usually several different diameter. And the recesses must have a serrated notch.

Sometimes pliers can be confused with pliers. combined type. 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.

AT modern models to capture parts of different diameters, not a set of recesses is used, 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 steel increased strength chrome vanadium and chromoly. The degree of hardening reaches fifty-three, according to HRC.

Pliers equipped with plastic handles, can be used in electrical work Oh. 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 sampling 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 work 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 for biting solid 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.

Some types of tools simply must be in any house or apartment, even where it would seem that they are not needed. One such tool is a pair of pliers. It is a versatile household helper that can be used to hold, pull, bite and crimp, flatten, hammer and so on. In this article, you will learn about how to choose and how to buy pliers, what you need to know and do for this.

Description of pliers

The tool belongs to the family of pliers and devices, and is one of the first types hand tools. Pliers came from pincers, because their device is almost exactly the same - for example, two connected halves (the working part and the handle) are connected by a special hinge, so this method of fastening and arranging pliers classified the tool as pliers-hinged tools. In order to choose a tool, the first thing to do is to decide on the type of pliers, since over the long time of their existence, several varieties have appeared.



Types and differences of pliers

The most popular today, on the tool market, are electrician's pliers (or combined pliers). This type made of electric tool steel, and the working part of such pliers is hardened in oil. Of the additional distinguishing features, it is worth noting the additional hardening of the working edges, which are hardened not under the influence of high temperature, but under the influence of high-frequency currents. Thanks to this, they reveal very useful qualities and tool properties. So, it is ideal for working in electrical networks– during the laying of cable channels, for laying wiring, for gripping and cutting wires, for bending wire or crimping sleeves.



Adjustable pliers are also a fairly common type of tool that is made from durable, hardened steel. The surface of these pliers has electroplating, and the tool itself is perfect for both assembly production, and at home use, or use it at a service station.


Folding pliers are a fairly popular tool, both among professional craftsmen and among tourists, for example. Such pliers are made of heavy-duty steel, and their feature is versatility and compactness. So, this tool combines several tools at once (a saw, scissors, a ruler, a corkscrew, etc.). Therefore, such a tool will be extremely convenient for the repair or installation of objects.

How to choose pliers?

To choose and buy pliers correctly, before you need to decide on the type of tool. If you know exactly which of the above types you need, follow the further selection criteria. To do this, you need to know such characteristics as:

- m material for making pliers;

- Rdimensions and parameters of pliers;

- dadditional possibilities.

Plier material. Absolutely, all types of pliers must be made of quality material - tool steel, chrome vanadium or chromium molybdenum steel can be used for this, and also, the design of the pliers can be combined. The jaws of the tool can be made of titanium alloy, or hardened steel (if it is an electrician's pliers, hardened under high-frequency current). As the material of the handles, polyvinyl chloride or dielectric plastic, rubber, and so on are most often used. Among other things, pliers can be additionally coated with an anti-corrosion varnish layer.



Plier sizes. Enough important characteristic are the dimensions of the tool. So, the standard for the manufacture of pliers involves the manufacture of tools with dimensions of 130, 160, 180 and 200 mm. There are exceptions, during which pliers are made larger or smaller. The most widely used are pliers, with sizes of 160, 180 and 200 mm. An important feature also is the hardness of the material from which the pliers are made. According to the Rockwell scale, it should be at least 43-50 HRC.

Pliers are one of those tools that is always in the kit of any master. And quite rightly, since with their help you can perform many useful manipulations, which will be discussed in the article. I will also pay attention to the intricacies of choosing such an indispensable device and introduce you to specific offers from manufacturers.

Device

First of all, we stop confusing pliers and pliers with each other, which home craftsmen love to do, but the pros do not allow themselves. Both of these tools are pliers and are even a little similar in appearance, but at the same time they are strikingly different in structural elements.

Considering these two devices, it is fair to note that it was pliers that appeared earlier, the working part of which are elongated metal clamps equipped with inside fine serrations for improved grip. And only then someone had the idea to modernize them.

The difference was formed by the following fragments:

  1. notched notch, allowing to carry out a strong grip even round and spherical products. Also, thanks to this seemingly nondescript change in the design of the “lips”, it became convenient to use a tool for tightening bolts and nuts in cases where there are no suitable keys nearby;

  1. Side cutters. Closer to the hinge mechanism, the pliers have sharp blades, making it possible to remove insulation from wires and bite thin wire;

  1. cutters located on outside hinge. With their help, you can cut already thicker wire fragments or even a chain-link mesh.

Thus, the difference between pliers and pliers lies precisely in three described additions. Similar in them are only the jagged tips of the "spouts".

Varieties

The device in question, despite the fact that they are practically universal tool and a faithful companion of any master, is still divided into separate types, which should also be understood:

Combined or locksmith

In fact, this is exactly the type of pliers that we have already considered.

They can:

  • snack wire;
  • take out nails;

By the way, if you hold the nail when you hammer it with pliers, and not with your hands, then exclude the possibility of hitting your fingers with a hammer.

  • hold on elements of the assembled structure and much more.

Dielectric

It's the same tool, but with insulating coating on the handles. The instruction obliges this type of pliers to be able to withstand a voltage of at least 1000 V, which, as a rule, is indicated on the handle itself. That is, this device can work with electrical wires and devices connected to the power supply.

For eyelets

Eyelets are metal rings that are used to install banners, streamers and even curtains. The tool that helps to install them is already quite different from the classic pliers and is more unusual hole punch than just advanced pliers. With its help, holes are made in the material, into which the mentioned iron rims are then mounted.

Adjustable or tubular

As can be seen from the figure, this type of instrument under consideration can change the diameter of its serrated notch, which makes it indispensable in the first place when replacing or installing a pipeline. After all, it can be adjusted to rounded products of various diameters.

Assortment of building stores

What are pliers and how they differ from pliers, you already understood.

Now I will help you navigate among specialized stores, familiarizing you with the most popular positions and giving a couple of tips on choosing:

I do not recommend saving on this type of tool. The fact is that a cheap sample Bad quality will not be able to perform its functions at all, but a quality representative famous brand will serve you for decades and will be inherited by children and grandchildren.

  • Fifteen-centimeter model from the Swiss company "OREOL":

When buying, first of all, pay attention to the hinge mechanism: it should have a smooth, backlash-free ride. Only in this case, the instrument can be considered of high quality.

  • Eighteen cm model from the Swiss company "ZCL":

In the closed state, there should not be even the slightest gap between the “sponges”. This indicates a high-quality assembly of the sample.

  • Model "DEXELL 180 mm, CR-V":

Make sure that the handle shells fit securely and do not slip off. This is a mandatory quality for compliance with safety regulations, especially when it comes to a dielectric tool.

  • The multifunctional model "Dexell - 15 functions" is useful not only in locksmith work, but even on a hike, as it contains, in addition to the main working part, knives, nail files, openers and many other useful built-in tools:

  • Model of miniature pliers from the Swiss company "OREOL":

Weight also plays big role. On the one hand, it is more convenient to work with a light fixture, on the other hand, a shortage in mass can mean the use of a low-quality alloy in the manufacture of a tool.

  • Dielectric model from the Polish company "TOPEX":

  • Fifteen-centimeter model of the firm "Brigadier":

It does not hurt to take a piece of wire with you to the store. good pliers should be easy to cut through. If it doesn't, choose a different instance.

  • Adjustable "DynaGrip" model:

  • Adjustable model "MaxSteel VDE 1000V":

Conclusion

You learned what pliers are and how they differ from pliers. The video in this article contains additional data regarding the material discussed. And in the comments you can ask any questions on the topic.

For many builders and craftsmen, pliers and pliers are one and the same tool. However real professional knows that these are somewhat different adaptations, albeit very similar to each other. In this material, we will consider such a tool as pliers, you will find out what they are intended for and how they differ from pliers. In addition, you will learn how to choose and buy the most successful and suitable pliers for you.

What is the difference between pliers and pliers?

The main difference, according to which these two twin tools are distinguished, is that the pliers, in their design, have one or two pairs of notches made in a serrated shape. These notches allow you to grip and rotate classic or cylindrical parts. Among other things, on the surface of the flat part of the sponges, and on the recesses of the pliers, there are notches, which pliers do not have.



Tool design

Note that according to the type of work performed, the design of this tool may be different. Therefore, pliers come in at least two different designs:

- P accessories with elongated jaws;

- Paccessories with short lips.

Speaking of pliers, in which the shape of the jaws is somewhat elongated, it is worth noting that these jaws can be up to 200 mm in size, and they are a bench tool with which it is convenient to manipulate, hold, twist or pull out elements, parts and other objects. Such a length of the jaws, among other things, will make it very convenient to cope with overall details. As for the pliers with short jaws, their hallmark is, a small opening and dilution of the jaws, which is of the order of 35 mm or less.



Also, pliers should be distinguished according to their purpose, thus, they distinguish:

- dand electric pliers;

- andeyelet tool;

- and, combined pliers.

To distinguish one or another type of the instrument we are considering, it is enough to look only at the appearance. However, if you do not know how to distinguish pliers by their appearance Let's take a closer look at the details of each of them.



Dielectric pliers have an insulating handle, which ensures safety when working in electrical networks. Such pliers can work at voltages up to 1000 V at alternating current, or at a voltage of 1500 V at direct current. This tool has molded streamlined handles that allow you to quickly and safely carry out all electrical work with comfort. Dielectric pliers are widely used when installing electrical wiring or equipment in an apartment - when installing sockets and meters, switches, chandeliers, installing and laying wires, and so on.

Pliers for eyelets are also a fairly common tool from the arsenal. professional master. Actually, it is not difficult to guess that such pliers are designed for mounting eyelets, as a rule, with a diameter of up to 7 mm. Eyelets, in turn, are designed for arranging curtains and curtains, so using this tool, the installation of these parts will be quick and comfortable. To do this, you just need to fix the eyelet in the area of ​​\u200b\u200bthe jaws of the pliers, and fix the ring along the edge of the material with a few vigorous compressions.



Combined models of pliers are a universal tool, since they combine several functions at once, assembled from various plumbing tools - pliers, cutters for fine wire, side cutters and so on. As a rule, combination pliers are made of high-strength carbon steel and also, the cutting edges of the jaws are hardened, which increases the service life several times.



Among other things, the surface of the pliers is covered with a special anti-corrosion coating or varnish, which will prevent the formation of rust or corrosion on the metal surface.

The right choice of pliers

In order to select and buy pliers good quality, it is enough to refer only to some details during the selection. First of all, you should pay attention to the materials from which the pliers are made - good, high-quality tool steel should be used as the basis, and dielectric plastic or rubber (and more modern options these materials). Do not forget about the manufacturer of the tool - well-known manufacturer his name alone inspires confidence in the tool, so refer to such pliers and pliers.

We will not hide that in any household it is very useful to have pliers. The versatility of pliers is confirmed by the practice of conducting household: twist, then fix or install again. Among the variety of tools among the variety of home craftsmen, it is pliers and pliers that noticeably distinguish and give deserved attention.

Pliers for the home master

Pliers are multifunctional hand tools. Successful combination functions of pliers and comfortable handles allow you to work on clamping, grasping and holding various parts and elements in a given mode.

According to regulated regulatory requirements, pliers and pliers are made industrial way from steel grades that ensure the fulfillment of specifications and loads when testing bench tools. At the same time, the hardness of the cutting elements of the hinge, the edges of the jaws and the clamping surfaces should not be lower than the recommended HRC values ​​on the Rockwell scale. Before starting the selection, it does not hurt to know the difference between pliers and pliers.

How to distinguish pliers from pliers

Pliers and pliers are considered to be pliers designed for carpentry, carpentry and electrical work on the wiring of low-voltage electrical networks. In the arsenal of a home master, the presence of these tools is a must. With the use of pliers, it is possible to clamp or capture not only parts of various configurations, but also pipes of small diameter.

What is the difference between pliers and pliers? The difference from pliers is obvious, because pliers have one, less often two pairs of notches of a serrated shape. Serrated recesses are designed to capture and rotate parts of a classic cylindrical shape. In addition, the pliers are decorated with a notch, which is located on the recesses and the flat part of the jaws.

Pliers design

According to the type of work performed, the design of the pliers may vary. I make pliers in the following versions:
with elongated jaws
with short lips.
Pliers with elongated jaws up to 200 mm are a bench tool designed for manipulating, holding, twisting and pulling elements and parts.

The advantageous length of the jaws allows the use of the two-way leverage rule on gripping jaws and cutting edges. Pliers are equipped with ergonomic handles with overlays.

Pliers with short jaws are small in size, opening the inner jaw and breeding up to 33 mm.

Types of pliers

There are the following types of pliers:
dielectric pliers
pliers for eyelets
combined pliers.
To find out what type of pliers belong to, just look at their photo.

dielectric pliers

Dielectric pliers are distinguished by handles with electrical insulation according to IEC (IEC) 60900, in which it is allowed to work with tools and equipment with an operating voltage of up to 1000 V alternating current, as well as up to 1500 V DC.
Soft cast handles of pliers, streamlined shape with insulation allow you to comfortably and safely perform electrical work.

So, for example, plastic knipex pliers are successfully used when installing electricity meters in an apartment. The safety of work is ensured by the body of the handles, made of plastic reinforced with fiberglass. Reliable electrical insulation completely eliminates the possibility of impact electric shock. The handles of the pliers have a ribbed surface, which excludes any slip during installation. Flat jaws tools are equipped with teeth that provide a good grip. With a small weight of pliers of about 130 g and a length of handles of 180 mm, work with pliers long time not burdensome.

pliers for eyelets

The most popular tool for a home craftsman can be confidently called pliers for eyelets. Moreover, a metal or plastic ring - a grommet with a diameter of up to 7 mm is often used in the arrangement of curtains and curtains for apartment windows. Thanks to the presence of pliers for installing eyelets, installation is quick and comfortable. With the help of pliers, the installation of the eyelet is simplified to a minimum: a few vigorous squeezes with the handles and the metal rings are completely fixed along the edge of the material.

combined pliers

Models combined pliers combine several functions of a metalwork tool: these are pliers, cutters for thin wire and side cutters. Models of combined pliers are made of carbon steel, and the cutting edges of the jaws are hardened for a long service life.

The metal parts of the pliers are processed and polished, and also coated with anti-corrosion varnish. The handles of combined pliers are made of two materials of the same type, the handles are comfortable in the hand due to the ergonomic design.

How to choose pliers

If the home master does not intend to carry out complex electrical or plumbing work, and the work carried out will be episodic, then acquire an expensive professional tool not necessary. It will be enough to purchase household pliers. Which quality parameters should pay attention when choosing?

Certainly this quality material tool making. The best pliers are made from high quality steel. The fact that this is really steel and the brand mark can be seen with your own eyes on the body of the pliers in the form of an engraving. It is also necessary to pay attention to anti-corrosion coating tool. The best coatings are chromium and vanadium. By the way, the shiny lips of the pliers are not an indicator excellent quality. Get in direct contact with the pliers. If your palm feels confidently protected from slipping, and there are no external reinforcements of the handles with pins, then the handshake can be considered friendly.

Such a "friendly interface" will serve in good stead home master. And, of course, test drive the pliers. Well, here without "divorce" is simply not enough. Spread the handles of the tool and follow the smoothness of the move. Repeat the procedure several times. If, with the eightfold “divorce” of the pliers, not a single muscle flinched on the face of the saleswoman of the building supermarket watching your manipulations, this means that it is time to pay for a new convenient tool.
