Photo of the difference between pliers and pliers. The difference between pliers and pliers Pliers what they are for

05.11.2019

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

These are hand tools that 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 - that's far from complete list professionals who need 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.

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:

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.
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.
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.
The versatility of some and the narrow focus of others.
Various GOSTs and technical requirements manufacturers upon release.

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" comes 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. 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 the oval recess, have a cutting edge, and sometimes in the area of swivel on different planes of the tool there is also a selection for cutting hard metal wire.

AT modern models to capture parts of various diameters, it is not a set of recesses that is 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 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:

Form of working sponges. For pliers, it is even, with small notches, and for pliers - with oval selections.
The size. Pliers (their photo is presented in the article) are usually larger in appearance, have massive clamping jaws, often short.
The presence of a rotary hinge of an adjustable type indicates that we have pliers in front of us.
Multifunctionality is inherent in pliers, and the narrow focus of application is inherent in pliers.
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, as it is technically impossible to equip them with insulating handles. The steel grade from which this tool is made is not of high quality, so these pliers belong to a purely domestic 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.

In this article we will look at what types of pliers exist and what is important - how to choose them correctly.

But judging by the number of questions, many people do not know the differences between pliers and pliers. And we need to understand this, because the tools were created for different things! Their thoughtless use does not improve the result of labor.

There will always be craftsmen hammering nails with adjustable wrenches. But I believe that our audience is inquisitive and skillful people. Therefore, let's figure it out.

Are these pliers or pliers?

Mounting pliers and pliers have two movable parts, fastened together by a hinge. Therefore, both classes of tools belong to the category of pliers.

Scope of SGI:

mounting
plumbing work
electric installation work

With these tools, you can remove the nail from the plank, tighten the nut, and replace the faucet box in the bathroom. But only dielectric shgi are suitable for working with electricity, which can withstand a certain voltage without risk to the health of the worker.

Housing materials

Pliers and pliers are made of tool steel grades CS45, CS55, chrome-vanadium. The latter material is used less frequently and is more expensive, but the best in hardness and wear resistance. CS55 follows immediately after chrome vanadium, and CS45 is used for budget hand tool.

An important quality parameter of a material is its hardness, measured on the Rockwell scale. Designated by number and signature "HRC".

Then the metal is processed by volumetric hardening and covered with a protective layer using:

oxidation
chrome tinting
phosphating

Both classes of tools have two types of handles:

One-component - entirely plastic or rubber-coated. Suitable for use in aggressive environments. Plastic handles are attached with glue, in some cases the handles can turn or fly off - if they are poorly glued. Plastic is also not without drawbacks - it slips out of the palm when working with gloves. Rubberized handles are held tenaciously, pleasantly felt in the hand, but are easier to scratch and cut in the process.

Two-component handles - basic plastic or impact-resistant plastic plus rubber cover. Plastic gives strength, including when falling from a height, and the rubber coating eliminates slipping of the handles in the palm of your hand.

So, with the general details it is clear. What is the difference between pliers and pliers?

Let's talk about this in more detail.

Pliers are a tool with flat jaw surfaces, hence its name. It is necessary for uniform gripping of workpieces.

The clamping surfaces of the pliers have only teeth and sometimes cutting edges, but no notches. Ideal for holding small parts, wires and fasteners.

You assemble and repair electronics, mechanisms, up to watches - you need pliers.

Another option in this group is the bending of wires and metal plates. Smooth surfaces without recesses allow you to capture the workpiece over the entire area without additional damage to the materials.

Later we will take a closer look at the types of special pliers for precision work, but first we will deal with pliers.

Pliers are a multifunctional tool and have a clear focus for power work. The word itself is French, it can be translated as "rod clamp".

You can’t name assembly and jewelry work strengths pliers.

The fact is that the tool is made with combined jaws: there are recesses for gripping cylindrical parts: rods, thick wire, nails, screws.

There are also flat clamping surfaces, they are always made with a serrated notch, which increases the clamping force of the jaws. Therefore, pliers can capture parts, but you risk damaging the workpiece. It is more logical to use pliers for roughing.

Be careful, pliers are often confused with combined-type pliers: the latter can also have an oval notch, but are additionally equipped with a cutting edge for separating wire and fasteners. Also, in the hinge area, there may be an additional recess for cutting the same wire.

A number of models of pliers are produced with a sliding hinge - in order to spread the jaws wider and capture workpieces of a larger diameter.

Since pliers are more powerful in their purpose than pliers, they use a material of greater strength and hardening. If the hardness rate for pliers fluctuates around 47 HRC, then for pliers it reaches 53 HRC.

Pliers combine the functions of several tools, so they are more often bought. However, pliers are indispensable for precision work and work in confined spaces. It is convenient to keep both at home.

How to use pliers:

The pliers must be lubricated, otherwise they will not move, or the lips will come together sharply, jerkily - this way you can hurt your hand.
Choose pliers so that when closing, they do not pinch your fingers.
Clamp both flat and cylindrical parts with pliers.
When working, do not push, but pull the handles of the pliers.

Types of pliers

The VIRA tool range includes a range of assembly pliers household appliances, electronics, and in some cases, these products are simply convenient to use in small niches in the walls, when working in recesses and holes in the ceiling, floor.

We openly indicate the parameters of our tools on the site, and what materials we use for them.

Long nose pliers. They perform similar functions to pliers, but due to the elongated and narrower gripping parts with a serrated notch (already 10 mm), they make it easy to grip screws and small parts of the assembly. The cutting edges are designed to work with wires and wire. Steel material CS55.

A variant of the modified tool with curved jaws - platypus pliers. The good thing about this tool is that it allows you to get to wires and fasteners in curved or angled spaces. Both serrated clamping surfaces and cutting edges are available here. Again, they are more suitable for wire and wire, not nails. Steel material CS55.

Why do we need round-nose pliers: for curly bending of wire. Cone-shaped jaws allow you to bend workpieces with a radius of up to 0.6 mm. Mainly used by manufacturers jewelry. The working part is made of high carbon steel CS55.

All precision pliers are produced with two-component handles. We use impact-resistant ABS plastic as a basis for them, and additional comfort is achieved through TPR rubber inserts.

This is a rough and elastic material that lies softly in the hand, while the tool does not slip in the palm of your hand even when working in the rain.

Another representative of the SHGI VIRA group is side cutters. The tool is specially designed for cutting wires, as it has only a cutting edge, without clamping surfaces. The key property of a tool is its cutting properties. A great option for an electrician, installer and repairman.

Many people are interested in the difference between wire cutters and side cutters. One could write a separate note about this, but in short, side cutters are a kind of ticks.

Metal processing

To protect VIRA pliers, we use metal oxidation or burnishing. This helps protect the instrument from moisture and rust. With this treatment, pliers can last 5 years longer.

quality standard

All VIRA SGIs comply with the requirements of the German Geprüfte Sicherheit (GS) standard. This sign denotes products that meet the safety and quality of production.

How to use pliers:

Check tool lubrication. It gets to the store already well lubricated, but it is better to make sure of this. Without lubrication, the clamping surfaces will not move and the pliers will rust.
Pliers are not designed for clamping large parts. Use the tool for medium and small workpieces.
Tools do not involve aggressive work. Excessive pressure on the handles spoils the condition of the cutting edges, teeth of the clamping surfaces over time. In addition, the appearance of the machined parts suffers.
Grab the flat parts of the workpieces with pliers.
When working on live parts, hold only the handles of the pliers (only dielectric pliers are suitable for this)
Pliers are not suitable for cutting hard materials such as steel.

How to choose pliers

Check hinge.

Pliers should not “walk” too much at the place where the moving parts are fastened. Take the tool in your hands horizontally, with the sponges away from you and try to shake the pliers by the handles up and down. A joint in a hinge without much play indicates the quality of the assembly of the tool. Strong backlash - the moving parts fit poorly.

Check the convergence of the jaws

The clamping surfaces of the tool must be sufficiently pressed against each other during mixing. This is important for tools used in precision work, because if the jaws do not come together well, small parts and fasteners will fall out and not be held.

Handle comfort

Make sure that they are securely held and do not fly off, pleasant to your hand, do not slip in the palm of your hand. If the handles scratch your fingers and hand at least a little, then with constant work, calluses and scratches await you.

I hope that now you know the difference between pliers and pliers and can make your own choice in favor of a tool that suits your own purposes. In addition, now you know what types of pliers exist and what they are for.

Pliers - this is the name of a tool belonging to the pliers type. With its help, various manipulations with objects are performed, and their scope extends from construction to medicine. For example, in dentists, teeth are removed with pliers. At home and repair work use such varieties of ticks as pliers and pliers.

The difference between them is not obvious to many. However, they differ not only in appearance, but also in their functional purpose. Each type of work requires certain devices.

Pliers

In almost any kind of locksmith work, these tools are used. All of them consist of a head, a handle and a movable axial joint.. Since ancient times, blacksmiths have used large tongs in their work, with the help of which they held the workpiece on the anvil.

Over time, society, craft and tools have changed. Simple pliers have been reborn into a range of multifunctional and useful gadgets. There were round-nose pliers, wire cutters, pliers and pliers.

Main features and differences

GOST defines pliers as a tool for clamping and gripping pipes, as well as parts of various shapes. In appearance, they are very similar to pliers. In addition to the working area, they have flat jaws, which are a continuation of the area for gripping pipes or bolts. Often this tool is equipped with side cutters for stripping insulation and cutting wire of small diameter.

Main differences:

Pliers are a multifunctional tool, pliers are designed to perform one action.
Pliers have flat working elements, with a notch along the entire length.
The pliers have cutters for cutting thin wire and cavities for clamping tubes, and durable steel is used in their production.

Pliers allow you to solve more problems in the process of various household works. In many ways, they are able to replace end cutters, small household vise or side cutters, and capture almost any small object.

Pliers

Pliers are related to metalwork and assembly tools. With the help of sponges of rectangular section and pyramidal shape, they capture various objects or bend wire, metal parts.

Due to the low functionality for household work, this device is the least popular among tool buyers, who in most cases prefer pliers.

According to GOST, domestic-made pliers are available in two versions:

with short jaws from 25 to 55 mm and long (from 50 to 63 mm);
with simple handles and insulating, for work under high voltage.

The total length of the tool is in the range of 12–22 cm. In production, U7A tool steel is used with hardening up to 45 units. Ready product subjected to anti-corrosion treatment in one of several ways:

chemical oxidation;
chrome plating;
chemical phosphate.

The color of the product directly depends on the processing method and can be black, matte gray or metallic.

In addition to standard samples, you can see on sale their other varieties, designed for a certain type of work. For example, "platypuses" are pliers with elongated jaws resembling tweezers. However, due to the powerful handles, they have a greater grip force. Or pliers with bent jaws - for working in hard-to-reach places.

pliers

If you take pliers and pliers in one hand, the difference between them will become obvious. Pliers stand out brightly solid appearance thanks to a more powerful design and additional functions. They will more reliably hold almost any part, confidently capture the surface of a cylindrical shape, nuts, bolts or studs.

Some modifications may have grooved hemispherical recesses on the inside of the handles, which can be used as crimps.

For the production of this tool, chrome vanadium and chromium molybdenum steel are used, which makes it more durable than pliers. The handles are made of dielectrics that allow you to work under voltage up to 1000 V. However, before starting such work, you must make sure that the pliers are marked accordingly.

The pliers of some models allow adjustment of the clamping force of the jaws. By rearranging a special hinge in the desired groove, you can increase or decrease the width of their disclosure. This is required to grip much larger parts than standard tools are capable of gripping.

There is just a huge number of different hand tools that can be used in the work. The most common can be called pliers. They are used in everyday life and in the organization of professional activities. A fairly common question is what is the difference between pliers and pliers. These differences are taken into account by all masters when choosing a hand tool. It is worth considering in more detail pliers and pliers, what is the difference between these designs and other points.

Pliers

Mankind has been familiar with blacksmith's tongs for many centuries. It is not yet known exactly when the instrument in question was made. Exist different kinds pliers:

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

Moreover, each group has several of its subcategories, which have their own form and purpose. For example, it is possible to properly process the cores when using round-nose pliers. The curved conical shape of the working surface allows for convenient bending of the cable end.

Varieties and uses of pliers

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

Sponges are flat, have applied notches. In this case, the sizes of the sponges can vary significantly.
The cutters are connected using a hinged design.
To transfer pressure, the design has special handles that can be made using various materials.

A good tool is made by various companies that specialize in the production of similar products. For the convenience of carrying out various works, the design is performed in several versions. There may be significant differences between them. The following pliers are widely used:

It should be borne in mind that in order to work with various electrical equipment or conductive products, special pliers with handles made using insulating material are required. The manufacturer is obliged to write on the handles the maximum voltage with which you can work. Information can be written using a variety of technologies, many will exclude the possibility of overwriting during long-term operation. If the maximum voltage is not indicated, then the use of the tool is strictly prohibited.

There are two main groups of pliers:

Classification is also carried out according to the size of the product. The master, who often uses the tool in question, may have several options for the execution of pliers in the kit: larger size, the more force can be transferred, smaller models are suitable for working in hard-to-reach places.

The difference between pliers and pliers

All tools are designed for use in carrying out a specific job. The differences between pliers and pliers are in the following points:

Considering how pliers differ from pliers, it should be noted that the first version is multifunctional, the other is suitable for a small amount of work.

It is necessary to choose the most suitable tool correctly in order to provide the most comfortable conditions for performing work. The fact that the design can consist of several elements determines the difficulties that arise when choosing. The best way performance can be selected taking into account the following information:

It is recommended to pay attention to the offer of exclusively well-known manufacturers. This is due to the fact that they value their reputation and apply only the most quality materials and also checks all manufactured products.

Transfer force adjustment

On sale you can find products that allow you to adjust the compression force. Similar models can be used when the workpiece to be processed should not be subjected to mechanical stress.
