Pliers are also called. What they consist of, what they look like and what makes good pliers different. Origin of the word pliers

Pliers are an essential part of any craftsman, be he a professional locksmith, installer, plumber or electrician.

They can grip, hold, bend and twist various objects, including those under voltage (when using dielectric models).

How to choose pliers

• The first thing to consider when choosing a tool is for what purpose it is needed. If the product is required as a working manual tool of the master, then their professional types should be considered.

Varieties intended for domestic purposes are not suitable for constant use and increased loads.

• The second criterion is the manufacturer. A high quality tool, if properly used, can last for many years.
• You need to pay attention to the performance and functionality of the pliers. Electricians should definitely choose electrically insulated models. It is desirable for professionals to have several types of products for different types of operations.
• It is advisable to choose the handles of the instruments that are ergonomic, repeating the anatomical shape of the hands. In the case of prolonged use during a work shift, the hands of the foreman will be less tired.
• When choosing hand tools, color matters, as black pliers, for example, are difficult to find in dark rooms.

Therefore, it is advisable to give preference to models with a bright coating of the handles. Nowadays, you can even buy pliers with fluorescent coated handles that will glow in the dark.

• When choosing a product, you need to check it by squeezing the handles. In this case, the jaws of the tool must close tightly and evenly.
• The desire to save money on hand tools and the purchase of goods not from authorized dealers may entail the purchase of non-original products.

This will be a waste of money as it won't last long. A counterfeit will not meet security requirements.

1. It does not matter what kind of decorative coating the product body has (chrome, nickel, etc.), that is, the external beauty of the instrument. This has absolutely no effect on the functionality and other essential characteristics of the product.
2. The presence of additional functions in highly specialized models (most likely, they will not be useful).

• The best combination pliers are Knipex. Their manufacturer is a German company that produces high quality hand tools according to VDE standards.

Pliers from this company can bite through hard wire. They are the most expensive, yet durable, ergonomic and highly efficient.

• Pliers for professionals under the brand name Bahco (Sweden) are among the best and are produced in factories in western Europe and the USA.

Products comply with ISO standard. All Bahco combination products are electrically insulated.

• Brand tools IRWIN (USA) are also professional and of high quality.

The electrically insulated combination pliers from this manufacturer are VDE compliant, but have a shorter service life than the above models.

The combination product has wire cutters in the middle and on the sides (side slots in the hinge area). In addition, the pliers have a notch with notches for gripping small diameter, rounded objects.

This model is designed primarily for gripping and manipulating wires and cylindrical objects. Modern pliers can be equipped with a return spring or adjustable joint for adjusting to different pipe sizes.

Pros:

• multifunctionality,
• versatility.

Minus: most often household orientation.

• Corresponding company products BeadSmith is a high quality silicone grip that is non-slip and fits well in the hand.

They are ideal for straightening wires and working with brittle material, but they are quite expensive.

• Model HTP-18 with nylon pads Micron is the most popular in Russia due to its excellent combination of price and quality. It has high functionality despite its budgetary cost.
• Tools with nylon tips manufacturing Beadalon(USA) are functional and easy to use, but their quality is no better than that of the cheaper Micron model.

Pliers for jewelry making and other similar work are made with nylon tips (tips).

It is a tool with non-slip grips and soft protection on the jaws to prevent scratching fragile parts. They can also be used for domestic purposes.

Since this model is not designed to work with live electrical installations, its handles are not properly insulated from electric shock.

In addition, such tools are not reinforced and do not have a large margin of safety. They cannot be used for other purposes, since they will quickly become unusable from improper use.

• Wire stripper pliers BAHCO 2223 S-150 made of high quality alloy steel with plastic coated handles, oxidized and anti-corrosion treated; able to clean the wire up to 5 mm.
• Wire stripping pliers KRAFTOOL made of high quality carbon steel with plastic handles and anti-corrosion coating.

These products are of good quality at an average price, but can strip wires only up to 2.5 mm.

• Stripping pliers " ZUBR ELECTRIC», High-voltage high-quality tool steel, have a resistant chromium-nickel coating.

Wire stripping pliers are electrically insulated. They are suitable for electrical equipment with voltages up to 1000 V AC and 1500 V DC.

With these tools, you can strip wires up to a maximum of 5 mm. Their mechanism allows you to remove the insulation without damaging the conductors.

Such products are safe and functional, but they cannot be used for other purposes.

1. BAHCO 2713 A in vanadium steel, chrome-nickel coated and anti-corrosive.
2. Adjustable pliers USAG (Italy) made of chrome vanadium special steel with 7 positions and enamel finish.
3. ProsKit PN-P010N (254 mm) in S45C steel with insulated handles.

Adjustable pliers are a type of pliers that allows you to change the opening width of the jaws depending on the size of the object you want to grip.

Such models have latches for setting a certain opening width. They can grip both flat and round objects.

When squeezing the handles, the jaws of such a hand tool should come together tightly.

The regulation mechanism is performed with the hinge relocation:

• in the holes;
• in half holes;
• with fixing of the projections in the grooves.

The ability to change the position of the jaws is an undoubted advantage of this type, but the disadvantage is a certain bulkiness.

1. Electrically insulated company models Knipex there are combined (ordinary and special power), as well as in the form of elongated pliers.
2. All pliers Bahco are electrically insulated (side cutters, wire cutters, pliers, round-nose pliers, bolt cutters). The quality of these products is practically not inferior to Knipex, but the price is slightly lower.
3. Electrically insulated combination models, platypus, wire strippers, side cutters and needle-nose pliers under the brand IRWIN (USA) are of high quality and safe.

This type allows you to service electrical installations with alternating voltage up to 1000 V or constant voltage up to 1500 V.

The dielectric pliers are equipped with well-insulated handles to ensure the craftsman is safe from electric shock. Good tools have multiple layers of insulation. They are easily recognizable by their thicker handgrips.

Different models of pliers can be dielectric. This increases their functionality and safety. However, some manufacturers' models do not have a limiter.

1. Adjustable pliers - wrench KNIPEX made of chrome vanadium steel, forged, oil-hardened. They are quickly rearranged by pressing one button.
2. Adjustable pliers Bahco with 11-12 positions, switching by 1 button.
3. Adjustable pliers IRWINforged carbon steel with anti-pinch protection.

Sliding models allow you to grip rounded, hexagonal, square and flat objects as tightly as possible. The jaws of such a tool have a bend.

The dimensions of the sliding pliers are larger than those of simple types. The opening width of the jaws is adjustable in some cases by pressing a button and can be adjusted with one hand. The grip width can be up to 45 and 65 mm.

1. Side nippers KNIPEX Made from electric furnace vanadium steel, oil hardened, precision machined for long service life.
2. Side cutters Bahco (high quality alloy steel with anti-corrosion treatment) with progressive cutting edge geometry.
3. Diagonal cutters IRWINmade of chrome-nickel steel with hardened cutting edge.

The side pliers have a cutter on one side of the jaws. In fact, these are wire cutters designed for cutting (biting) objects made of various materials.

The side cutters can be used with wires of different stiffness, plastics, sheet metal, cardboard, etc.

When operating this model, it must be borne in mind that the variety intended for cutting copper will not cope with elements made of harder materials (iron, steel). This will damage the cutters of the tool.

1. Long nose pliers KNIPEX.
2. Products with long lips Bahco.
3. Long nose pliers IRWIN.

Long nose pliers are called long nose pliers, pliers, or needle nose pliers. They are designed to grip and manipulate objects (primarily wires) at a greater distance than conventional models.

These tools can be equipped with wire cutters.

Most often, this model is used to insert wiring into junction boxes, when laying wires, as well as when connecting electrical installations. They are also widely used by jewelers to fix stones in jewelry.

1. Round nose pliers KNIPEX made of forged chrome vanadium steel, oil-hardened, heavy duty.
2. Model with round jaws Bahco made of high quality alloy steel with anti-corrosion treatment.
3. Round nose pliers IRWINmade of chrome-nickel steel.

Tools with semicircular jaws are designed for working with wires. They come without or with cutting edges. With cutters, such products, in addition to gripping and manipulating the wire, can also bite the wire.

The semi-circular jaws are specially designed to grip uneven surfaces. They are made from hardened steel. The tool is in demand for fitting, assembly and repair work.

Advantages of the view: you can work in hard-to-reach places with round holes. At the same time, their weak point can be called a small area of \u200b\u200bthe working surface.

1. Recycling Pliers AIST made of chrome vanadium steel.
2. Impact mechanical tools Matrix made of chrome vanadium steel.
3. Multifunctional Fishing Products Frichy FPN 02 made of polished stainless steel, equipped with a fixation for safe wear.

Multifunctional (impact-mechanical) pliers can be used for the main purpose, as well as a hammer.

This model is equipped with long handles and a metal striker for impacting various objects (nails, etc.). Such products have a fairly large weight and increased dimensions.

There is also a multi-functional (recycling) model. In addition, there is a folding model on the market that is equipped with a knife, an opener and a set of screwdrivers. This product is best suited as part of your camping equipment.

Pliers and pliers can be found in any home. At least once, everyone had to use them in everyday life or at work. They are used when working with different materials, during the repair of various electrical equipment and technology. But despite the fact that they are widespread and often used, few people manage to call the tools by their proper names.

Types of pliers

From the name it is clear what kind of tool the tool should have - these are flat jaws, which have transverse notches of varying degrees of frequency, articulated connection and handles... Monolithic parts, as a rule, are the working part and handles. This tool is indispensable in plumbing or electrical work, since thanks to them it is possible to hold any part of any shape, to bend wire or metal in the right direction.

Pliers can replace a whole set of wrenches. However, it should be noted that these tasks are completely unusual for this tool, but if you do not have the right size wrench, then pliers usually come to the rescue, which cope with screwing and unscrewing all kinds of bolts and nuts perfectly. Pliers are different from each other dimensions and shape of the working part:

• So, if you need to work in a hard-to-reach place, then pliers with elongated narrow jaws will provide invaluable help in this.
• Tools bent at a certain angle can reach the part even from under a covered surface, for example, a screwed-on board in electronics.
• "Platypus" are pliers, which have elongated lips like tweezers.
• To work with especially delicate materials, special tools are used, as well as silicone nozzles that are worn on ordinary models.

The tool differs in addition to the working part and the handles. For example, dielectric pliers are useful in electrical installations. On this type of tool, it is imperative to look for the maximum voltage value that must be indicated. After all, this is an indicator of whether the material from which the handles are made can withstand it. Household models have this indicator up to 1000 V... If you do not find such a number on your instrument, then it is strictly forbidden to use these pliers under stress conditions. There is a high probability that this tool belongs to plumbing and is not intended for work with electrical equipment.

Pliers

This name is borrowed from the French language, so this product must have come to us from abroad, but no one has ever thought to prove it. The main difference between this swivel sponge tool and pliers is in the notched grooves, which are convenient when gripping smooth and rounded surfaces, for example, pipes of small diameter.

Pliers are no longer available in pure form. It is often possible to find a "mix" with the same pliers when the front working surface is flat and side cutters and wire cutters are placed closer to the hinge part. Such "convenience", as a rule, are not inherent in pliers. Some models specifically simplify, creating only not one, but two notches of different diameters for work on gripping rounded surfaces. Other pliers are equipped with an adjustable joint that allows the grip to be extended.

Pliers cousins

Do not forget about round-nose pliers, which, unlike other similar tools, have jaws with a round cross-section, tapering towards the ends. Them convenient to bend the wiremaking bends with different radii. The models of this tool are various: round-nose pliers are produced with different sizes of jaws, curved working surface, with and without notches. But in general, they remain similar to their older “brothers” - pliers with the same dielectric handles and wire cutters.

Some cutting pliers resemble pliers. The exception is cutting edges that cut through metal of different thickness, depending on their capabilities. Nippers, in turn, are subdivided into end and side cutters. In everyday life, side samples have become the most popular. When choosing these products, you should consult about what types of metals they can bite into.

After all, there are tools only for copper wire, but some are capable of overpowering even nails. Today there are reinforced modelsable to bite through rope or reinforcement thanks to increased cutting edge strength and multiple pivot points for greater gripping force.

Difference between pliers and pliers

So, if we summarize all of the above, we can conclude that the differences between these tools are as follows:

When it comes to buying a hand tool, it is better spare no money... In electrical mechanisms, it is possible to save on a minor function, for example, fifth speed, or an additional attachment, but in the manufacture of simple tools, if there is an opportunity to save, it is only on the loss of quality. It follows from this that if your capabilities allow, then it is better to purchase professional tools. The differences between common and expensive products will be felt so much that you quickly come to the conclusion that you should thank yourself for such "extravagance".

Appreciate with a glance working surface clamping strength, only uniform contact is allowed. When squeezing and unclenching, you should feel a smooth and soft ride. The handles should have a very reliable fixation, because low-quality products “suffer” from slipping, which is inappropriate when working with electricity.

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

Pliers tool

Humanity has been familiar with the blacksmith's tongs for centuries. It is not yet known exactly when the instrument in question was manufactured. There are different types of pliers:

1. Ticks.
2. Classic design.
3. Round nose pliers.
4. Pliers.
5. Nippers.

Moreover, each group has several of its subcategories, which have their own form and purpose. For example, it is possible to correctly process the veins using round-nose pliers. The curved conical shape of the working surface allows you to conveniently bend the end of the cable.

Varieties and use of pliers

Pliers are the most common type of these tools. The required tool has the following design features:

1. The jaws are flat and have notches. In this case, the dimensions of the sponges can differ significantly.
2. The pliers are connected using a hinged design.
3. To transmit pressure, the structure has special handles that can be made using different materials.

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

It should be borne in mind that 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 value that can be operated. Information can be written using a variety of technologies, many will exclude the possibility of mashing during prolonged use. 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 by product size. The master, who often uses the tool in question, may have several pliers in the kit: the larger the size, the more force can be transmitted, smaller models are suitable for working in a hard-to-reach place.

The difference between pliers and pliers

All tools are designed to be used in a specific job. The differences between pliers and pliers are in the following points:

Considering the difference between pliers and pliers, it is worth noting that the first version is multifunctional, the other is suitable for a small amount of work.

The most suitable tool should be chosen correctly in order to provide the most comfortable working conditions. The moment that a design can consist of several elements determines the difficulties that arise when choosing. The best execution option can be selected taking into account the following information:

It is recommended to pay attention to the offer of only well-known manufacturers. This is due to the fact that they value their reputation and use only the highest quality materials, and also check all manufactured products.

Adjusting the transmitted force

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

Pliers - this is the name of a tool belonging to the hinge-pliers type. With its help, various manipulations with objects are performed, and their field of application extends from construction to medicine. For example, dentists remove teeth with mites. In everyday life and during repair work, they use such varieties of pliers 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. For each type of work, one or another device is required.

Pliers tools

Similar tools are used in almost any kind of plumbing work. They all consist of a head, a handle and a movable axial joint... Since ancient times, blacksmiths have used large pliers in their work, with which they held the workpiece on the anvil.

Society, craft and instrument have changed over time. Simple pliers have evolved into a range of versatile and useful tools. Round nose pliers, wire cutters, pliers and pliers were introduced.

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 tubes or bolts. Often this tool is equipped with side cutters for stripping and cutting small diameter wires.

The 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 nippers for cutting thin wires and cavities for clamping tubes, and they are manufactured using strong steel.

Pliers allow you to solve a larger number of tasks in the process of various household work. They are largely capable of replacing end cutters, small household vices or side cutters, and grab almost any small object.

Pliers

Pliers belong to fitter's and assembly tools. With the help of sponges of rectangular cross-section and pyramidal shape, they capture various objects or bend wire, metal parts.

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

According to GOST, Russian-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 high voltage work.

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

• chemical oxidation;
• chrome plating;
• chemical phosphating.

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 intended for a certain kind of work. For example, "platypuses" are pliers with elongated lips, resembling tweezers. However, due to the powerful handles, they have a large compression force. Or curved-jaw pliers for hard-to-reach places.

Pliers

If you take pliers and pliers in one hand, the difference between them will become obvious. The pliers stand out for their solid appearance due to their more powerful design and additional functions. They will more reliably hold almost any detail, confidently grip cylindrical surfaces, nuts, bolts or studs.

Some modifications may have grooved hemispherical notches on the inside of the handles that can be used as crimps.

This tool uses chrome vanadium and chrome molybdenum steel, which makes it more durable than pliers. Handles are made of dielectrics that allow work under voltages up to 1000 V. However, before starting such work, you must make sure that there is an appropriate marking on the pliers.

Some models of pliers allow adjustment of the compression force of the jaws. By rearranging the special hinge to the desired groove, you can increase or decrease the width of their opening. This is required to grip much larger parts than standard tools can handle.

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 the 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 their 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 nippers.

Types of pliers. Features and scope

Already from the name the characteristic appearance of this tool 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 locksmith, 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 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, it will be impossible to use side cutters. 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 not be any 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.
