Where is the joint on pliers? Pliers. Types and device. Work and features. How to choose. Main features and differences

The most common and universal tool At home or at work, pliers are considered. Tighten a nut, cut a piece of wire, remove a part from a hard-to-reach place - we are used to doing all this with the help of such devices, so as not to waste time searching for individual special devices. Many hobbyists call them pliers, which is incorrect. They belong to the same class of hand tools, but their purposes differ.

Types of pliers equipment

The detailed composition of such devices consists of cutting, or clamping, jaws, handles and an axial shaft. Such instruments came to us many centuries ago. Since then, their scope has expanded and their appearance has changed. Each of these devices has its own design of the sponge part, dimensions and methods of application.

A tool in the form of tongs with long handles and short flat, less often pointed, jaws is called pliers. They come in metalworking, blacksmithing, and electrical installation (crimping devices).

A special type of ticks - wire cutters, wires. Their incisors are located in different planes.

Design specifics

This type of tool also includes pliers. They are used for their needs by electricians, mechanics, installers and all home craftsmen. In French dictionary there are terms from which the name of the most universal of pliers tools comes. They mean “rod and hinge” and literally describe the design of the device.

This tool combines wire cutters and pliers in one mechanism. Do not use them on hard or large materials: this will lead to breakage or deformation of the jaws or handles. Cutting on the working part allows the canvas to clearly fix the object.

The middle area of the jaws has cutting surfaces. Their location makes it possible to snack on only one side. The existence of cutters is the main difference between pliers and pliers. Appearance working part different options about the same.

From overall size The tool depends on the transmission of applied force, and other capabilities and characteristics are almost identical.

Different manufacturers introduce various new features, special sharpening and hardening into the design of the cutting device to improve the consumer qualities of the product. It is impossible to unambiguously choose a leader in this category.

Characteristics of pliers

Still, the difference between pliers and pliers is small. Many people classify devices with a flat working part as a separate class of tools. They are identical in design, and in use the difference between pliers and pliers is not too noticeable. For thin, straight parts, the first fixture is more suitable. Their main action is bending wires, wire and sheet metal.

There are several special types pliers:

with curved working parts for operations with microelectronics;
round with points - for removing retaining rings. Narrow ones replace tweezers in tight spaces;
A variety of softening attachments allows you to work with fragile parts.

Very often the same operation is performed with different devices. However, the difference allows some of them to be used more effectively. Small differences between pliers and pliers:

pliers have a wider range of work performed;
the shaped surface of the pliers allows you to hold the part more tightly;
thinner jaws allow the pliers to get into hard-to-reach spaces;
the working part of the pliers is spread as wide as possible; for pliers, this range is limited by the hinge lock;
pliers, due to their design, compress the object more strongly.

Quality requirements

You need to carefully examine how the instrument is assembled. You can visually evaluate the design by looking at the closed position of the jaws: equal rectangles indicate decent quality of the tool. The permissible gap is a few tenths of a millimeter. This ensures full use of the device. Many manufacturers are experimenting with moving joint designs to make work easier and extend service life.

Metal Features

The service life and performance of work operations depends on the raw materials from which the pliers are made. Any stage of production, both hardening and quality of steel must correspond to the technology. The hardness of the metal must be selected to avoid breakage, deformation and chipping. These are usually high-carbon steels. Regulatory document for pliers, GOST 17438–72 “Pliers. Specifications", gives answers to any question about these devices.

To prolong the life of the joint, the accuracy of its fit and physical properties of wear resistance are critical.

Surface treatment

Working with various tools occurs in any weather and in a variety of rooms. Under unfavorable conditions, metal objects have a habit of rusting. For this Anti-corrosion coatings are applied to the metal surface in various ways:

Very often, manufacturers resort to bluing. That's an example simple way avoid exposure to moisture. The hot workpiece is dipped into machine oil and painted with a special varnish, however, after such an operation the product becomes fragile.
Chromium treatment gives required properties, and besides, it looks beautiful: chrome plating enhances the steel shine.
In terms of its ability to withstand mechanical stress, a galvanized product is superior to all previous ones, but has a noticeably less presentable appearance.

Handle qualities

The quality of work results depends to a large extent on comfortable conditions when executing it. Convenient operation using pliers depends as much as possible on the shape and material of their coating. The handles of such devices come in the following categories:

Simple plastic attachments for the unpretentious user at a low price. The plastic must be fairly flexible to allow free compression.
Special ergonomic rubber inserts provide tools for frequent and long-term use. They lie comfortably in your hand and do not slip out even from sweaty palms. The only requirement is that the material for the pads must be hypoallergenic.
Dielectric handles allow you to use pliers under a voltage of 220 volts.

Plastic elements must adhere firmly to the metal base. The most reliable and least expensive product is considered to be a hot fit, when plastic insulation is put on the heated ends.

It is important to comply temperature regime to avoid plastic spreading. Sometimes iron rivets are inserted as fasteners. Such a tool loses its dielectric properties.

Types of pliers

Of the entire family of pincer-like devices, they have the most numerous variations. This is due to the variety of applications for such equipment. Their areas of application may overlap.

Dielectric tool

These are ordinary pliers with pronounced electrical insulating properties. With their help, work is performed without relieving stress. Proven tools are one of the means of protection: in installations up to a thousand volts they will be basic, above - additional.

Plastic and comfortable handles allow you to perform all operations as comfortably as possible and do not slip out of your hands. To increase the dielectric properties, a layer of fiberglass is often added under the plastic.

The structure of the sponges guarantees effective adhesion to the object of influence. Such devices are extremely light and compact, preventing contact with live elements in cramped environments.

Device for installing eyelets

This name is given to iron or plastic bushings or rings less than seven millimeters in diameter. They strengthen the edging around holes in shoes, workwear made of leather or rubber, thereby preventing the material from tearing. Installing such accessories requires skill. Nowadays this operation is performed using eyelet pliers.

In everyday life, they are used when installing curtain systems and make this process much less labor-intensive.

Combination devices

This modification combines the capabilities of numerous plumbing equipment. These instruments must meet all quality requirements for any type of sponge-joint instrument.

The most common because of their versatility are sliding or adjustable devices with a variable gap between the jaws. They are popularly known as Goebbels pliers, or parrots. This is a kind of mix of pliers and an adjustable wrench. Of course, you can’t dismantle a rusty connection with it, but for plastic pipes this is the most suitable tool. They are also good for unscrewing fasteners with a lost head or broken edges: even a stripped screw will give in.

When deciding to purchase a good tool, you need to determine its main purpose. Requirements that will help you choose a quality tool do not depend on its price and are quite universal:

Which tool is better should be determined not by description, but by holding several models in your hands.

Precautions during operation

An installation tool, like any other, can cause injury if not handled carefully. Therefore, some rules for using pliers and similar devices must be observed:

do not unscrew rusted or tightly clamped fasteners;
bite the wire carefully so that the flying piece does not damage anything;
plastic insulation is tightly fitted to prevent slipping;
dielectric handles must not be damaged.

Remember that a quality tool is never cheap. Well-known manufacturers treat product quality more responsibly than fly-by-night manufacturers who can replace good raw materials with worse ones.

Best models

Among the many manufacturers of products in this segment, several stand out, offering reliable, original designs.

Thanks to the quality of its products and original developments, Bahco stands apart in the market of plumbing tools. The Bahco 2628 model is distinguished by an original hinge: one of the halves is made of an asterisk, and the material in this place is less hard. This provides moderate play, which is initially absent at all. Another know-how is the return spring on one of the handles. If you don't need it, you can turn it off.

Gedore 8245−180 pliers were produced by a company that has a bias towards professional, power tools. This device also has an original hinge part with a round-shaped gear pressed into the handle.

Chrome-plated metal withstands loads well, the material of the handles is resistant to dirt.

NWS - famous manufacturer of tools for professionals. The quality of the products is indicated by the markings on the products of Solingen, a world-class manufacturer of special steels, whose products have been known since knightly times. Some models have original design- transparent insulation with small polka dots for better grip on the palm.

Of course, you don’t have to buy equipment that costs tens or hundreds of dollars for everyday use. Cheaper and better quality tools are available for sale everywhere. The main thing is not to make a mistake in your choice, and working with pliers will only be a pleasure.

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. Big encyclopedic Dictionary technical terms defines pliers as a hand-held metalworking and assembly tool equipped with pyramidal-shaped jaws rectangular 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 To protect against corrosion, apply 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.

Find 6 differences

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.

One of the most common tools are pliers and pliers, but not everyone knows what their difference is, so let's try to figure it out. These tools are used by both professionals and home craftsmen. Locksmiths, electricians, mechanics and other specialists cannot do without them. IN household Often there is a need to carry out various types of work, the performance of which is almost impossible to do without these devices.

Many people believe that these are the names of the same tool, but they are mistaken, since pliers and pliers are different from each other. Although they are similar in appearance, each of them meets its own technical requirements during production and has different GOSTs.

Types of pliers tools

This type appeared a long time ago and is constantly being improved, new types appear.

Round nose pliers are used when soldering microcircuits.

Types of pliers tools:

pliers;
round nose pliers;
mites;
pliers;
wire cutters

In addition, each species also has its own subspecies, differing in the size and shape of the sponges. Each model has its own purpose. For example, to bend cables of different diameters, use a device with cone-shaped jaws. For convenience, such models can additionally be equipped with wire cutters.

If you need to work with plastic or other fragile parts, use special attachments. The round pliers have special notches, which helps to fix parts more reliably, and the fact that they have such a jaw shape allows you to work in hard to reach places, for example, when soldering microcircuits or carrying out other work.

Nippers can have different sizes and shapes of the cutting part. To work with thick cables, more powerful wire cutters are used; they are not suitable for working with radio components; here you need small wire cutters.

Features of pliers

The name itself indicates the shape of this device; pliers have flat jaws on which notches are made. The tool is used when performing various plumbing, electrical installation and other types of work. With its help, you can simply and reliably hold parts, bend cables, metal, the tool is often used instead wrench for loosening or tightening nuts.

In addition to the difference in size, the pliers differ in the type of working surface:

for work in confined spaces, elongated jaws are used;
in electrical engineering, elongated jaws curved at a certain angle are often used;
there are tools in the form of tweezers with flat lips, the so-called “platypuses”;
To work with fragile materials, special attachments are used.

When performing electrical work, there is a great danger of electric shock, so devices used when working with electrical tools and wires must have specially insulated handles, on which the manufacturer indicates the maximum voltage value that they can withstand.

Most often, a device with protection up to 1000V is used for domestic use. If the pliers have rubber handles, but the voltage value is not indicated, then they are not intended for electrical work - they can only be used for plumbing work.

Features of pliers

They are direct relatives of pliers, so their scope of application will be similar.

The working surface of the pliers must have a notch with notches.

Its presence allows you to securely hold the parts.

Sponges usually have a combined shape, and their edge is made in the form of pliers.

Some models may have two different sizes of recesses, which allows you to hold parts of different shapes and sizes.

There are models in which the hinge can move in the grooves, thus, it is possible to regulate the compression force and the amount of opening of the jaws, which allows you to work with parts of different sizes using pliers.

Most of these devices have side cutters with which you can remove insulation from the cable; they may also have special edges that allow you to cut hard wire. Pliers are available for metalworking and electrical work, therefore, the handles of the latter must indicate the voltage value at which it is safe to work with them.

The main differences between pliers and pliers

Having examined the design and purpose of these devices, we can highlight their main differences:

The shape of the working surface of the pliers is flat and does not have a special recess.
Using pliers, you can create significantly greater forces, so they are made from higher quality steel.
Pliers have the ability to adjust the degree of compression and jaw gap, but pliers do not have this ability.
Pliers are more universal; they have side cutters and a device for cutting wire, which pliers do not have.

How to buy a quality instrument?

Carpentry and carpentry tools: a, b – wire cutters, c – pliers, d, e – pliers.

It is best to purchase a professional tool, but keep in mind that its cost will be more expensive than one intended for everyday use. A professional tool is of better quality, it is more reliable, if you didn’t buy a fake, it will last you a lifetime, it will serve reliably and always do its job efficiently.

One of the main features of a high-quality model is the hinge, which should not have any play, its movement should be easy and smooth. Another sign of quality professional tool is the absence of clearance when the jaws of pliers or pliers are closed. The surface must be flat and they must be adjacent to each other over the entire plane.

When choosing a power tool, pay attention to the quality of the insulation on the handle. It must sit tightly, not move under any circumstances, and it must indicate the maximum voltage at which such pliers or pliers can be used.

As you can see, there is no big difference between pliers and pliers, both are used to perform similar work, but there are still some differences. In a household you need to have both, then you can independently, without outside help do all the housework.

To help modern masters Many different tools are produced, both electric and mechanical, manual. The undoubted leader in the latest classification is the hammer, which everyone knows, and everyone has held in their hands at least once in their life. This impact tool is slightly inferior to the pliers, that is, its popular representatives are pliers and pliers. These assistant masters have also been in the hands of many. They are used in repair work for gripping, supporting, twisting parts and consumables.

Pliers or pliers – what to choose for the job

Almost every home has a tool cabinet, even if the owner rarely repairs anything himself. There will still be mandatory set, consisting of:

hammer;
screwdrivers;
pliers or pliers.

And if the first two tools are familiar to everyone and the scope of their application is clear, then with the latter everything is not so simple, since it is rare where both tools are available at once. At first glance, it will seem to the average person that pliers and pliers are no different. For a professional this is not the case. A craftsman will immediately name the main differences between pliers and pliers.

Taking a closer look at one and the second tools external difference obviously. Only the structure of the handles is the same, but the working part of the pliers and pliers, which is called the lips, is completely different and depends on the purpose.

When do you need pliers?

By the name you can guess that the working part of the pliers is flat, there are only a few notches. The tool consists of lips, handles and a hinge joint. For ease of use, some manufacturers produce pliers with a collapsible joint. If necessary, it can be disassembled for lubrication or troubleshooting. The notches applied to the lips perform the main working functions: holding and gripping. This helps craftsmen cope with:

with twisting of wires and sheets of metal;
with loosening screws, bolts and nuts;
with bending wire and other consumables.

Using pliers, various plumbing and installation work with parts is performed different sizes. For ease of use of the tool, the industry makes several modifications:

With elongated narrow lips, making it possible to work in places with limited access.
With angled jaws to help you reach the desired part in electronics or other hard-to-reach mechanisms.
With elongated long jaws designed for a strong grip on components and material.
With a set of attachments that allow you to perform repair operations on delicate and fragile parts. Pliers are also divided by size (maximum diameter of parts is 200 mm) and by the presence of special insulation on the handles. When purchasing, you should pay special attention to the last factor. If there is special insulation and the corresponding markings are applied to the handles (1000 V), then these pliers can perform various electrical installation and electrical repair work. In the absence of an insulating layer and markings, the tool is only suitable for plumbing, and approaching electricity with it is already life-threatening.

The difference between pliers and pliers is obvious when listing job functions. The range of applications of the second tool is much wider than that of the first. Pliers are often called the older or younger brother of pliers, or humorously modified pliers. The notched lip design and adjustable swivel joint enhance the tool's capabilities.

Using pliers you can:

capture and hold parts of different volumes by adjusting the hinge;
strip and cut insulated wires;
work with round parts.

Depending on the presence or absence of special recesses, cutters and notches, several tool models are produced:

Combined, perfect for everyday use for installation and plumbing work.
Combined adjustable ones expand the range of applications with the ability to work with pipes and round objects of different diameters.
Dielectric ones have special insulation on the handles and markings. They are used for working with electrical equipment and wires.
Eyelet pliers are convenient for installing rivets, rings and various holders.

The choice of pliers model depends on what the tool will be used for. The first two are perfect for the home.

What to buy: pliers or pliers?

Pliers and pliers are a bit similar both in appearance and in use. The choice of one of these two tools depends on the future use. After all, the difference between pliers and pliers is:

different forms of working surfaces;
multifunctional use of pliers due to additional notches, notches and cutting edges;
the presence of an adjustable swivel joint for pliers and a fixed joint for pliers.

As experts suggest, perfect option- this is the purchase of both instruments, and even in a professional version, if finances allow. If money is tight, then for infrequent home use you can opt for pliers. Just don’t forget when purchasing them, as in the case of purchasing pliers, some rules:

The tool should be comfortable for the hand.
There should be no play in the articulated joint.
Gaps between parts when closed are not allowed.
The handles must fit securely - without slipping or twisting.
The tool should be light so that when using it your hands do not get tired from the heaviness, but not due to the unsuitable quality of the material.
You shouldn’t chase cheapness; a high-quality instrument doesn’t cost three pennies, and it very rarely falls into the category of promotional goods.

Pliers and pliers, related to pliers, can be found in any home. Each of us has used them at least once at home or at work. They are used to work with various materials, when repairing various electrical equipment and machinery. But despite them widespread and frequent use, rarely does anyone call these instruments by their proper names.

Pliers– a multifunctional hand tool used for plumbing and electrical work installation work. With its help, it is convenient to grab and clamp a variety of parts, regardless of their shape, including cylindrical ones. To grab and turn the latter, several grooves of different diameters were made on the jaws of the pliers with a notch applied to the entire working area. Intended for electrical installation work The pliers are equipped with special insulated handles designed for use under voltage of up to 1 thousand volts.

Also produced universal pliers, combining the functions of pliers, side cutters and cutters for cutting wire of various diameters. For the manufacture of the tool, high-quality steel is used, which has undergone several treatments. A special coating is applied to the finished tool anti-corrosion coating by chrome plating or oxidation.

Pliers

Pliers– hand tools used for various plumbing and electrical work. The jaws have a pyramidal shape with a notch applied to the flat internal surfaces. The working part of the tool, which turns into handles, moves using a hinge. Pliers are used to grab, bend and twist all kinds of small metal parts, wires and wires. There are several types of pliers designed to perform various works. They differ in the length and width of the jaws. The pliers are also equipped with insulating handles for working under voltage.

Differences

At first glance, pliers and pliers look very similar. Both of them consist of a working area (jaws), handles and a hinge that allows movement. Both tools are designed to grip, hold and bend various parts. Among the differences we can name different shapes sponge

On the inside of the pliers there are 1-2 pairs of grooves of different diameters with a notch applied, designed to hold cylindrical parts. Inner side pliers have a smooth 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. Depending on their purpose, pliers can have jaws of different lengths, widths and shapes (round-nose pliers, narrow-nose pliers, etc.). Pliers can be a multi-purpose tool that combines the functions of pliers, a side cutter and a cutter. Pliers are used for a specific action.

Conclusions TheDifference.ru

Pliers are multifunctional carpentry and assembly tools, and pliers are narrow-profile.
The inner surface of the pliers has several cylindrical grooves of different diameters; pliers have a flat surface.
The jaws of pliers are of standard width, and the jaws of pliers, depending on their purpose, have different shapes and widths.
The non-fixed hinge of the pliers allows you to change the opening of the jaws, but the opening of the jaws of the pliers does not change.

Take it, bite it, pull it! Combination pliers: device, main types and fine choices

Pliers are one type cutting tools, used in Everyday life with various renovations. With their help you can trim Various types materials without disturbing the structure of the element and achieving good cutting quality. There are different types of blades made that differ in their function. Let's look at their characteristics and applications.

Purpose of a wired mop

Cutters, according to their design, are universal tools for cutting metal and plastic products that work on the principle of a lever.

They are capable of cutting wire, electrical wire, power cable with a thickness of 5-7 mm.

Pliers are used when assembling and dismantling equipment, which is often required for electrical work.

What criteria should be considered when selecting this type of cutting tool based on the volume of use?

Design features

Since this tool is used to cut material, it should be selected according to the requirements to perform this function.

There are two main elements when designing wire cutting tools:

Handle for easy handling of the tool;
Cutting the cap, also called the jaws.

The type of knives is determined by such design parameters as the shape of the cutting edges, the characteristics of their location, and geometric dimensions.

The following types of blades correspond to the location of the cutting edges and function:

The end jaws are perpendicular to the surface of the handles.
For side knives, otherwise known as side knives, the position of the jaw is at an angle to the handle or on the same plane as it.
Cutting knives (screw screws) - used for cutting metal rods.

As a rule, to ensure electrical safety, the handles of this tool are made of insulating material.

Electric tongs are made of high quality insulation, which allows you to protect your hands from injury electric shock. The handle design is distinguished by two types of cabinets: insulated and insulated.

The difference between these types of handles is that the cover of the insulated wire blades is made of dielectric, and for insulating materials additionally equipped with cutting plates.

The device has guide handles, their surface does not soften or slip in the hand, it is resistant to moisture, technical oils and substances with high chemical activity.

Blade Types

Depending on the type of tooling tool, there are three types of clamps: ends, side knives and screw blades. All offered types of ticks can be purchased in the GSM online store.

edge

Pliers

It is used for assembly, in construction, and in the construction of electrical networks.

For the manufacture of the working element, reinforced steel with a chrome-plated surface is used. The cutting edges of these blades are highly durable and especially sharp to ensure the quality of work for which they are designed.

Handles made from dielectric tools are resistant to high operating voltages.

Side pliers

The worker is tilted relative to the tool's head. The effectiveness of the strongest knives of this type provides additional reinforcement and hardening using high-frequency currents.

We produce various models products that can cut wire from different metals and different thicknesses, from aluminum to steel.

Diagonal pliers for sawing steel wire with a thickness of 1.2 mm from steel products - no more than 2.0 mm and copper with a diameter of no more than 2.6 mm, heads inclined to the surface of the handle.

Ensuring flexibility of the working parts of the tool is characterized by high resistance to constant work of monotonous axle loads.

To produce professional side blades, we use tool steel, heat treatment and multi-stage hardening. The handles of this type of pliers are comfortable to grip and can withstand impact up to 75 kg.

Special pliers

One such type of cutting tool is the helical blade.

They are designed for bites with a thickness of no more than 12 mm. In its double lever design and equipped with long handles, first apply force to the increased intermediate value and then to the cutting surface.

The second type of specialty cutters are products used for cutting small electronic parts.

They have a mirror surface, evenly distributed, equipped with a device that removes static electricity. When you watch the video you present, you can see information about the cutters that are used to work the valve.

Types of wire cutters after use

In terms of use, one can distinguish following types pliers:

pins and reinforcing knives for wire work and fittings;
Electrical, designed to bite the cable;
Professional used to perform cosmetic procedures.

The first type of wire cutter is used for wires without ropes up to 4mm thick.

T8 steel, whose hardness is 42 HRC, is used for their production. The handles are 210mm long, polyvinyl chloride, and have hardened pads that are powder coated.

Electrical knives are used for cutting insulated aluminum and copper cables with a working diameter of no more than 35 mm.

For heat-treated stainless steel cutting edges. Knives are made using the method of volumetric stamping of steel, which falls from the height of a hammer.

The strength of the cutting edges ensures cutting of cables without significant shear deformation and internal wires.

The products are equipped with fiberglass and rubber handles.

Professional pliers are a tool for performing cosmetic procedures such as manicure and pedicure. They are small and designed to remove the shell. Professional pliers are made from strong stainless steel, which is used to make surgical instruments.

The metal undergoes special heat treatment, which makes its hardness reach 50 HRC.

Cutting food edges is a high-quality enrichment that ensures tool life.

Pliers

Some types of tools simply must be in any house or apartment, even where it would seem they are not needed. One such tool is pliers.

Pliers are different from pliers

It is a versatile household helper that can be used to hold, pull, bite and squeeze, 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 originated from pliers, because their device is almost exactly the same - so, the two connected halves (the working part and the handle) are connected by a special hinge, therefore this method of fastening and arranging the pliers is what classified the tool as plier-jointed tools.

In order to choose a tool, the first thing you need to do is decide on the type of pliers, since for a long time their existence, several varieties have appeared.

Types and differences of pliers

The most popular today on the tool market are electrician's pliers (or combination pliers).

This type is made of electric tool steel, and the working part of such pliers is hardened in oil. From additional distinctive 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 open up very useful qualities and tool properties. So, it is ideal for working in electrical networks– during laying 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 of durable, hardened steel. The surface of such pliers has electroplating, and the tool itself is excellent both in assembly production and for home use, or using it at a service station.

Folding pliers are a fairly popular tool, both among professional craftsmen and among tourists, for example.

These pliers are made of heavy-duty steel, and their feature is versatility and compactness. So, this tool combines several tools at once (file, scissors, ruler, corkscrew, etc.). Therefore, such a tool will be extremely convenient for repairing or installing objects.

How to choose pliers?

To choose and buy the right pliers, you first 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 pliers manufacturing material;

- R dimensions and parameters of pliers;

- d additional features.

Material for making pliers. Absolutely, all types of pliers must be made of high-quality material - for this, tool steel, chrome-vanadium or chrome-molybdenum steel can be used, and also, the design of the pliers can be combined.

The tool's jaws can be made of titanium alloy, or of hardened steel (if these are electrician's pliers, hardened under high-frequency current). The material used for handles is most often polyvinyl chloride or dielectric plastic, rubber, and so on. Among other things, the pliers can be coated with an additional anti-corrosion layer of varnish.

Plier sizes.

Enough important characteristic are the dimensions of the tool. Thus, the standard for the manufacture of pliers involves the manufacture of tools with dimensions of 130, 160, 180 and 200 mm. There are exceptions, in which pliers are made in larger or smaller sizes. The most widely used pliers are with sizes of 160, 180 and 200 mm. Important feature The hardness of the material from which the pliers are made is also important.

According to the Rockwell scale, it should be at least 43-50 HRC.

Among the additional features of pliers, it is worth noting such characteristics as the presence of cutting edges with which you can cut through wire.

Such edges are separately hardened to 62 HRC and higher. Thus, the choice of pliers depends not only on the type of tool, but also on its technical characteristics.

At first glance, pliers and pliers are indeed very similar and far from cooperating with them for a person whom they consider absolutely identical.

However, there are differences between them, which is confirmed, including the fact that their characteristics are regulated by different GOSTs.

What are pliers?

Pliers are some tools with articulated jaws with a flat working surface, as the name suggests. This surface often produces impacts of varying sizes.

Pliers vs. Pliers: What's the Difference and Difference?

Depending on the type of work for which the tool is used, its working part may be straight; curved; especially long and thin at the ends for working with small objects; on the contrary, it is short, which provides greater compressive force at the ends of the pliers. To avoid damaging fragile and fragile objects and parts, they have soft pliers.

What for whom?

Pliers are actually an extended version of pliers.

In addition to the work area, the recesses have:

less frequently, two recesses for capturing nuts and other cylindrical parts;
sharp sharp edges for cutting wire, nails and other thin metal products. When choosing a tool, it is worth considering how much diameter and material it can bite without interruption. For cutting screws, cables and fittings, it is better to buy high-pressure pliers.

Similarities and differences

What connects the clamp and the pliers is why they belong to a tool with articulated jaws.

You can use both tools when working with an electrician.

In this case, they must have insulating handles and the maximum permissible voltage. Without specifying this data, it is strictly prohibited to work with live wires and devices; such tools do not protect the user from current.

Additionally, both tools:

They are made of high quality steel with anti-corrosion coating.
They have courses and work zone- sponges.
Enable capturing of various objects and details.

The main differences between the instruments are the jaw configuration.

In addition, the loops of the pliers are not fixed, which allows you to greatly adjust the size of the jaw. Apparently pliers are much more versatile and can be replaced with multiple tools at once, and clamps have a much narrower reach.

In addition to pliers and pliers on tools using the jaw:

round pliers;
mites;
wire cutters

Everyone has general function, but a few different applications and configurations.

If you decide to lay a roofing covering, you will be able to handle it yourself, because the light weight of Euro slate sheets allows you to transport and install the material without special equipment and construction skills.

It can be used in the construction of roofs of houses, cottages, bathhouses, gazebos and other outbuildings.

Before starting installation work, it is recommended to read the instructions supplied by the manufacturer complete with ondulin and its components. In addition, the instructions have another function - it usually indicates the presence of a factory warranty.

The consumer has the right to make any demands in relation to the manufacturer only if all the conditions listed in the instructions were met when installing the ondulin.

It is also important that the legal guarantee applies to the original ondulin, which was purchased from an official representative or partner of the manufacturer.

In case of installation construction team, the customer must also know about the main stages of work in order to monitor the quality of the roofing installation.

List of rules for installing ondulin roofing

Each stage of work must be performed efficiently, in compliance with the specified rules. Thus, an incorrect calculation of the sheathing pitch will lead to incorrect installation of the entire roof, which will either have to be redone immediately or dismantled in the near future (read also: “Calculation of ondulin for a roof - properties and installation”).

As a rule, the instructions for installing ondulin involve minor deviations or the implementation of actions at the discretion of the developer, however, if there is insufficient experience in such construction, it is better to refuse to do it yourself.

Features of the installation technique of ondulin flooring

Below is suggested detailed instructions for laying ondulin coating.

At the request of the house owner, a window can be installed in the roof of the attic or attic, while the ondulin installation technology changes slightly: the material of the window opening is attached to the lower roofing sheet, and covered with a top sheet, while the overlap is taken into account for each layer of material.

How to properly lay ondulin so that the roof does not leak, details in the video:

When installing ventilation outlets through the roofing, you can use special outlets. The base of the structure passing through the roof is attached to all waves bottom sheet, and the top covering of the roof with ondulin is mounted on it, taking into account the allowance for overlaps.

During the process of laying the covering sheets and installing the ridge elements, a gap may form between these two components, which can be easily eliminated with a special filler. The quantity and method of its application depends on the ventilation system of the roof (read also: “Andulin roofing - types of material”).

Note that in some cases, developers install metal sheathing instead of wooden sheathing, then to attach the ondulin flooring you need to purchase a set of special self-tapping screws, and not nails, as with the classic version.

Thus, installing a roof using Euro slate will not cause any special problems if the rules listed above are observed, and a new roof made of lightweight, but durable and reliable ondulin, if the technology is carried out correctly, will serve for many years.
