Combination pliers types. Pliers and pliers: types and differences of pliers. What are pliers and the scope of this tool

Pliers and pliers are common and demanded tools, both in everyday life and among professional craftsmen.

Meanwhile, many people confuse pliers with pliers, not seeing much of a difference in them. The following explains the difference between pliers and pliers and which of these tools is the most popular and versatile.

Pliers by type

Pliers are different for their purposes:

• with short jaws for a firm and firm grip
• with extended jaws
• with narrow (or thin) lips
• curved - when working in hard-to-reach places
• with internal plastic covers to avoid damage to parts
• specialized, for working with wire

The working (inner) surface of the jaws is smooth or with small shallow notches - for a better grip of the object. The “jaws” are the part of the tool that grips the parts.

Differences between pliers and pliers

Pliers are a pliers' tool that looks like pliers. Some versions - no longer confused with pliers - use a reversible hinge mechanism. The jaws of standard pliers are usually shorter than the jaws of pliers.

The name “pliers” is French, literally “to clamp the rod”. And in order to clamp it tightly, on the inner part of the edges, always grooved - with notches, there is an oval or round depression, often two.

Pliers are a more serious tool

Pliers, unlike pliers, are designed for more serious work. Therefore, in terms of strength, the requirements for them are high. If the hardening level of the pliers does not exceed 45 units, then the pliers are hardened to 53 units. And the cutting parts - side cutters and cutters - are hardened to the level of 60 units.

Their metal is also good

Higher quality and metal from which the pliers are made. If carbon steel of a certain grade is used for the production of pliers, then chromium in combination with molybdenum or vanadium is used for the production of pliers.

Dimensions according to GOST

Pliers come in different sizes. There are “miniature” categories for delicate and precise work, for example, bench modeling or beading - 10 centimeters.

The dimensions of tools for installation, plumbing, automotive and other works are specified in GOST 17 438-72. For the first group of pliers, it determines the lengths of 160, 180 and 200 mm.

The second group, intended for industrial work, fits into three types of lengths - 200, 250 and 300 mm.

Imported products, made in the EU, USA and China, come in sizes 10; 11.5 and 14 cm.

What are the pliers

Different types of pliers are used in production and everyday life:

• Universal
• Dielectric
• Combined
• Elongated
• * Adjustable, sometimes called pipe
• For eyelets

If you compare photos of all the listed types of pliers, the differences are immediately striking. Their main functions and purposes are listed below.

Pliers for all occasions

Universal pliers, or as they are also called - locksmiths, are often incorrectly called pliers. They have a serrated notch after finely ribbed jaws. It is followed by side cutters - for cutting the wire, and next to the hinge, cutters for cutting more durable wire, nails and even the Rabitz mesh.

For live work

Dielectric pliers are designed for electrical work. They come with insulating handles, usually rubber or a combination of rubber with various types of dielectric plastics.

The mains voltage is divided into two types - in everyday life, 220 V. In production, the same 220 V and an additional 380 V. To avoid trouble, the insulating handles of the pliers are capable of protecting against 1000 volt shock.

Please note: this parameter is necessarily indicated on the pliers themselves, and not on its packaging. Since we are talking about human life, it is better to buy dielectric pliers from trusted manufacturers.

Eyelet pliers

Plastic or metal eyelets are designed to reinforce holes in footwear, leather goods and other industries and workshops.

In view of this, "eyelet" pliers are a highly specialized and highly professional tool. They differ from other pliers in a specific look and are easily recognizable.

The longest of the pliers

Long jaws are distinguished by elongated pliers. In some variants, the length of the sponges reaches 20 centimeters. Outwardly, they resemble tweezers to which the handles of the pliers are attached. They are designed to work in narrow slots or holes.

Like a penknife

This type is directly opposite to the narrowly specialized “eyelet”. It is called “combined pliers”. Such a tool is intended for various household chores. But they are also used by professionals as universal - for all occasions. But in this case, the tool must be from a quality manufacturer, otherwise it quickly fails.

The combination pliers are made according to the principle of a penknife or a Swiss knife and are equipped with a lot of functions and possibilities.

Usually, combination pliers are only part of a multi-functional kit that includes a number of necessary tools, such as screwdrivers with bits.

Plumber's pliers

Plumbing are the largest among the pliers. They are used exclusively for plumbing work. To grip large-diameter gas or water pipes, these tools use a movable hinge mechanism. Thanks to this, you can change - increase or decrease the diameter of the toothed recess.

Photo of the difference between pliers and pliers

Pliers and pliers are among the most requested tools. This is true for both professionals and DIYers. They are irreplaceable 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 diversity of the instrument market, it is difficult to imagine a more universal and necessary thing.

But why do we say they? Is there a difference between pliers and pliers? There is also a considerable one. It so happened that no one really makes any distinction between them. This is not surprising since they are very similar in appearance. But, nevertheless, there are very significant differences. 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 types of work are they intended 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. Humanity has been familiar with the blacksmith's tongs since time immemorial. As time went on, human society changed, and the instrument also 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 useful and practical.

There are many varieties of hinged pliers. These include:

• ticks;
• pliers;
• nippers;
• round-nose pliers;
• pliers.

Each category has "subspecies" with different sizes of the working surface (sponges), purpose and shape. For example, round-nose pliers are very convenient for cutting cable cores (shown below in the photo). 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 cutting pliers. 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 reliably fix the part while soldering the boards, and the special shape of the jaws allows you to get into the most inaccessible places of microcircuits (the angle of inclination of the jaws can be different).

The same goes for wire cutters. Different shape of the cutting part, its different size, different purpose. For example, wire cutters for repairing electronic equipment are smaller. For stripping cables, no matter what the purpose, they are not suitable. In theory, this is possible, but both the worker and the tool will be tortured. 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 instrument is "visible": flat jaws with applied notches, articulated joint and handles. Pliers are indispensable during any locksmith or electrical work. Due to the flat surface, they hold well any part of the shape. Pliers can bend cable strands, wires, wires and metal. The dimensions of the parts are due to the dimensions of the pliers themselves (usually not exceeding 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 not only divided by size. For the convenience of the user, manufacturers produce different types of work surfaces:

• elongated narrow jaws - for the ability to work in places with limited access;
• angled jaws are designed for hard-to-reach places, especially in electronics;
• the so-called "platypuses" are actually a kind of tweezers, but with great compression force;
• with special attachments for working 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 value that the insulation can withstand must be indicated. 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 locksmith's tool and the manufacturer simply does not provide for the protection of the user from electric current.

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

Combination pliers - practical versatility

Since the pliers are "relatives" of the 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 groove with notches. It is designed to grip and securely hold round and smooth surfaces. Typically, pliers have a combined jaw surface, 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 grooves 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 them into the required recess. In addition to the compression ratio, this also allows you to adjust the distance between the edges of the jaws, i.e. expands the range of sizes of gripped parts.

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

Some manufacturers extend the working area of \u200b\u200bthe pliers by notching the handles just behind the swivel joint. This allows you to grip the part not only with jaws. As far as is necessary and convenient, we will leave it to the users' judgment ...

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

Pliers and pliers - the difference

It's time to summarize. So what are the differences between pliers and pliers? There are three main ones:

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

The ability to adjust the clearance of the working surface of the jaws and the degree of tool force is provided only for pliers (this is achieved by rearranging the hinge);

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

1. If financial opportunities permit, buy professional pliers and pliers. This is not a whim, the difference between an amateur instrument and a professional one, even of the leading brands, is very significant. When choosing a power tool, you can save on professional equipment. It is not critical there. And in the manual very much. It's just a shame when, in the midst of work, you suddenly find yourself without pliers, or after 10 pieces of wire that have been bitten off, the side cutters cannot be used. The joy of such acquisitions will soon disappear. The same cannot be said about professional hand tools. If not a fake, then when used in everyday life, it will be enough for a lifetime.
2. Pay attention to the hinge, there should be no backlash. The stroke should be soft and smooth. This is a sign of a quality tool.
3. When the jaws of the nippers or pliers are closed, there should be no gaps, the surfaces should touch evenly, this is the key to high-quality production and assembly.
4. The handles on the handles must sit securely, free slipping and so on are not allowed. Especially for power tools.

Pliers and pliers are found in every home. Each of us at least once used them in everyday life or at work. They are used to work with various materials, in the repair of various electrical equipment and machinery. But, despite their wide distribution and frequent use, rarely anyone calls these tools by their proper names.

Pliers

Pliers - multifunctional hand tools used for locksmith and electrical work. With its help, it is convenient to grip and clamp a variety of parts regardless of their shape, including cylindrical ones. To grip and turn the latter on the jaws of the pliers, several recesses of various diameters were made with a notch applied to the entire working area. The pliers designed for electrical work are equipped with special insulated handles designed for use under voltages up to 1,000 volts.

Pliers

Universal pliers are also available that combine the functions of pliers, side cutters and cutters for cutting wires of various diameters. For the manufacture of tools, high quality is used, which has undergone several treatments. A special anti-corrosion coating is applied to the finished tool by chrome plating or oxidation.

Pliers

Pliers - hand tools used for various locksmith and electrical work. The jaws have a pyramidal shape with a notch applied to the flat inner surfaces. The working part of the tool, passing into the handles, moves with a hinge. Pliers are used to grip, bend and twist all kinds of small pieces of metal, wires and wires. There are several types of pliers for different jobs. They differ in the length and width of the jaws. Also, the pliers are equipped with insulating handles for live work.

Pliers

Differences

At first glance, pliers and pliers look very similar in appearance. Both of them consist of a working area (jaws), handles and a hinge that provides movement. Both tools are designed to grip, hold and bend various parts. The differences include the different shapes of the sponges.

On the inner side of the pliers, 1-2 pairs of grooves of different diameters with a cut are made, designed to hold cylindrical parts. The inner side of the pliers has a flat, flat surface with a notch applied, which serves for better adhesion to the parts being held.

The pliers have the same width along the entire length of the jaws. Pliers, depending on their purpose, can have jaws of various lengths, widths and shapes (round nose pliers, narrow nose pliers, etc.). Pliers can be a versatile tool that combines the functions of pliers, side cutters and cutters. Pliers are used for a specific action.

Conclusions site

1. The pliers are a multifunctional joinery and assembly tool, and the pliers are narrow-profile.
2. The inner surface of the pliers has several cylindrical grooves of different diameters, the pliers have a flat surface.
3. The jaws of the pliers are of standard width, and the jaws of the pliers, depending on the purpose, have a different shape and width.
4. The non-fixed joint of the pliers allows you to change the solution of the jaws, and the solution of the jaws of the pliers does not change.

There are many types of pliers. These include the familiar pliers, pliers, round-nose pliers, and pliers and pliers. Each listed tool is designed for specific purposes, has its own dimensions and shape of the working surface. The design consists of three main parts: a head in the form of jaws or cutters, an axial movable joint and handles. However, they all differ in their own individual qualities. In this article we will look at how pliers differ from 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 made on the inside of the flat jaws.

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

Types of pliers:

• A tool with elongated narrow jaws has less compression force and is used when working with small parts.
• In other pliers designs, the jaws bend 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 useful for electronic devices, where parts are hidden under the boards.
• For work with live parts, there are special dielectric pliers. Insulated handles allow free operation in the presence of electric current. Their handles are marked with the maximum allowable voltage at which they can work.

Pliers - a versatile tool

Pliers are the basis of pliers, which appeared much earlier and were intended to perform the most simple functions. As a result of modernization, pliers have turned into pliers and have become a popular multifunctional tool. The pliers are equipped with small side cutters, two small cutters on the sides. In the middle there is a round grooved hole through which small bolts and nuts can be tightened.

Installation and locksmith works are not complete without pliers. They function as pliers and can perform many additional operations. Thanks to their numerous attachments, the pliers work successfully on a variety of parts, regardless of their configuration. Thus, the pliers acquired the universal qualities of many tools at once. They became pliers, side cutters and cutters at the same time, capable of cutting a wide range of wire sizes and diameters. Some samples have the ends of the insulated handles with an awl and a screwdriver.

For installation and locksmith work, dielectric and combined pliers are mainly used. The first option refers to, the handles of which are insulated with special dielectric plastic. The second design is considered more versatile, combining various tools. This allows you to perform many plumbing 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 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 with pliers, which became a separate tool. Pliers can cut through almost any wire, while pliers have limited ability. The pliers securely grip any part, thanks to the existing grooves, and this cannot be done with pliers. Before choosing one or another tool, you need to decide in advance on 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. A large assortment of these products is currently offered, so the probability of error is becoming quite high. It is advisable to collect all the necessary information about the required instrument 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 reputable manufacturers rather than cheap Chinese products. The surface of the material should be uniform in all places, and all parts should be equally strong. The 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 work.

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

Often, pliers and pliers are considered the same type of tool, but this is wrong, because although these useful devices are for the same group of tools, they differ in design, characteristics, and functional purpose. How pliers differ from 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 need to understand what constitutes a pliers tool as a whole. This group of tools includes a variety of useful devices that facilitate the work of the wizard. The pliers can be called:

1. Ticks;
2. Nippers;
3. Round nose pliers;
4. Pliers;
5. 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 for repairing and adjusting electrical equipment.

Round nose pliers are best used 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 even broken. Therefore, it is so important to understand the difference between pliers and pliers, and to know in which work a particular type of tool is used.

Description and characteristics of pliers

The pliers have a special shape, as the name of the tool speaks for itself quite eloquently: the device is equipped with flat jaws with notches. 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 locksmithing, electrical work, and is involved in the repair of some mechanisms. Using pliers, you can achieve a firm fixation of parts, bend the cable or metal as needed, less often the tool can be used to tighten or unscrew the nuts.

A versatile tool for almost any task

Pliers come in different types and sizes, and the scope of the tool will depend on these parameters.

Types of pliers

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

1. Devices with extended jaws are used to perform work in narrow and confined spaces.
2. For electrical work, models with an elongated and curved shape of the jaws are more often used.
3. Pliers - "platypuses" are used as tweezers: its lips have a maximum length and are strongly extended forward. Another key benefit of the model is the increased compression force.
4. When working with fragile materials, pliers are used, the working surface of which either has no notches or is additionally equipped with a softening coating. For this type of instrument, you can additionally buy soft silicone tips.
5. There are also combined models that have a special groove on the working surface, which allows you to securely hold round parts. Pliers are also available with a cutting edge.
6. Sliding models will help you firmly grip hex, round or square parts. The jaws of such pliers have a strong bend, and the tool itself is larger in size than other types of models.
7. Side pliers are easily distinguished from other types by the cutter on one side of the jaws. A tool is used to cut elements from different materials: wire, plastic, sheet metal, cardboard.

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

Pliers with a semicircular jaw 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 tool jaws allows you to grip uneven surfaces, and therefore this type of pliers is in demand in plumbing and repair types of work.

Dielectric models with insulating handles are a separate type of tool, which allows the use of pliers in work under voltage. The permissible operating voltage is always 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 the 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 notch with notches on its working surface, which allows it to hold the parts as firmly as possible during work. Pliers jaws are most often combined in shape, and their extreme part is made in the form of pliers. Some models of the tool have not one, but two notches 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 hinge element movable in the grooves. By moving the hinge, you can adjust the compression force as needed, as well as the amount of opening of the jaws. The type of pliers under consideration is considered universal: it is applicable in working with parts of different sizes.

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

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

• Pliers have a flat working surface, without grooves;
• The design of the pliers gives the maximum possible compression force, therefore 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 tools in different types of work.

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

The size of the gap between the jaws. It should be no more than one 1 millimeter, and the tool handles should be connected 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 - the gap should not be more than 0.1 millimeter;
To perform electrical work, you should purchase electrically insulated models;
The handle of the instrument 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 that a detailed instructional article helped you understand what is the difference between pliers and pliers, find out useful details about existing types of pliers, find out the parameters for choosing high-quality pliers.
