In every house, regardless of its inhabitants, there is a certain set of tools that will always come in handy. One of these tools are pliers or pliers. Despite their superficial similarities, the two instruments have some differences. Both belong to a large group of pliers.
A story of this kind began long before our era: suffice it to recall the ancient Greek blacksmith god Hephaestus, who was depicted with blacksmith tongs and a hammer for forging.
This group includes pliers, pliers, pliers, wire cutters, round nose pliers. Each of the tools has its own production standards and is needed for different jobs.

What are pliers
Also, the tool is often used instead of a screwdriver when it is necessary to unscrew or tighten the nut. Pliers can only be used as a bending tool in some cases, since the width of the lips does not exceed 20 cm.
There are several types of pliers, differing in the types of lips.
The latter are:
- Elongated narrow: they are suitable for working with small objects or in hard-to-reach places. They have low compression force.
- Narrow curved: mainly used in electronics for access to the most "impregnable" places, for example, under the board.
- "Duckbill": These are pliers with strongly elongated jaws. In terms of functionality, they are similar to tweezers, but they allow you to compress the part more strongly.
For work with fragile materials, special nozzles with surface protection or without notches are used. For work with electricity, pliers with insulation on the handles are used: they must indicate the maximum current value. Most often, such tools can withstand up to 1000 V.
Note: using ordinary pliers when working with electricity is prohibited, since the handles are not protected.
What are pliers
Unlike pliers, the jaws of pliers have both a flat part and a small notch, which allows you to grip a workpiece with an excessively smooth surface more firmly. This makes the tool more popular and versatile. Some models have two recesses at once, for working with different sizes.
The tool is used for:
- clamping parts in the process of working with them;
- taking hot metals;
- crimping connectors in the absence of special tools.
Consider: pliers can also be used to tighten nuts, but this should be done only in extreme cases, as you can break the edges.
All varieties have their own characteristics, which are easy to see in the photo:
What are the differences
- The main difference lies in the surface of the jaws: for pliers it is straight, for pliers it has recesses for some details;
- The specialization of pliers is narrower: they are designed only to hold the part, all other functions (biting, tightening bolts) are not their “native” ones, which can lead to problems. Pliers are more functional: they can cut wire and metal, hold parts more firmly;
- For the manufacture of pliers, stronger steel is used, since the tool is designed for a greater compressive force;
- Pliers have a larger gripping range due to the presence of a movable connecting hinge. This helps expand the use of the tool;
- Often pliers are more expensive, as they are more functional.
Note: you should not save on the purchase: it is better to choose high-quality models that will last for several years than to change them regularly.
To make the right choice, you should pay attention to the following:
- the sponges must be intact, fit snugly against each other, not hang out, have no gaps or cracks;
- the handle should lie well in the hand, not slip and be comfortable;
- the connecting hinge should be strong, well tightened, but not tight, with a smooth, pleasant ride.
When choosing a tool, it is desirable to be able to try it out, hold it and adapt.
Many people think that pliers and pliers are one and the same, but they are not, although in some situations they can replace each other. Both tools, although they perform similar functions, have a number of differences that are worth remembering. When choosing a model, it is important to clearly understand their purpose in order not to buy a useless thing; it is also recommended to consider the models in the pictures in advance.

Repair work requires the use of a variety of tools. The most popular are pliers and pliers. Many believe that these are names for one device. This fundamentally erroneous opinion is quite common, but has no substantive justification. Professionals, of course, know how they differ from each other, but not home craftsmen who take out a tool box only in case of emergency.
Both pliers and pliers are practical and versatile. They, unlike many other tools, cannot be replaced by other devices. The confusion between these devices arises from the external similarity, but the difference between them exists. It is quite weighty. Both tools are involved in electrical installation and repair work, but serve different purposes. The only similarity lies in the fact that both devices are pliers.
What are pliers and the scope of this tool?
The device is a metal lips with notches, united by a swivel joint, as well as handles. The latter are made from various materials. They can be plastic or wooden. The handles are designed in such a way that the tool is most comfortable to hold in your hand.
Pliers have a flat surface. Due to the design features, with this tool you can easily hold hardware and parts of various sizes. Pliers are used to deform cable, wiring and products made from sheet material.
The dimensions of fasteners and parts have their limitations. The tool can hold hardware and products with dimensions not exceeding 19.5 cm. This is quite enough to carry out a wide range of work without any problems. In addition, pliers are often used as a wrench to unscrew nuts.
Tool varieties
The difference between pliers and pliers is not only in design and purpose, but also in the fact that the latter are produced with different shapes of working surfaces:
- With long and narrow lips. A similar kind of pliers is used where the usual size tool simply does not fit through.
- With curved lips. It is used when performing electrical work, when it is necessary to "slip" the tool into a hard-to-reach place where simple sponges cannot simply crawl through.
- With removable jaws. This unusual variety is used quite rarely and is designed to perform manipulations with parts made of fragile materials.
Pliers resembling tweezers allow you to work with fragile and small items. Thanks to this shape, the parts are not deformed or damaged.
Insulated pliers
They are a tool that is used to work with conductive devices. On such pliers, the handles are insulated, but this does not mean that you can take any such device. The value of the operating voltage must be indicated on the tool. If there is no such mark, pliers cannot be used. Otherwise, there is a possibility that the insulation simply cannot withstand the applied voltage, and this creates a threat to life.
Features of choice
If you plan to work with hard-to-reach places, you should purchase a tool with narrow and elongated jaws. When the required part is located under any surface, pliers with a curved working surface are required. They allow you to get, for example, a part screwed to the board. Platypuses, that is, a tool similar to tweezers, are used in cases where delicate work is required. Similarly, pliers and silicone tips are used, which are worn over ordinary sponges.
Pliers: description and purpose
The multifunctional tool is a "relative" of pliers. Both devices have a similar appearance, as well as purpose. This is what misleads many home craftsmen that pliers and pliers are the same tool. A closer acquaintance with this device allows dispelling this myth.
On each side of the working surface of the pliers there is a notch on which there are notches. The latter allow you to capture and hold surfaces from a wide variety of materials. Pliers are widely used in plumbing and electrical work.
The combined surface of the tool makes pliers one of the most popular tools. Along with the notch, the working area also has a flat area. In addition, in many varieties of pliers there are two shallow, small indentations. They allow you to work with parts of various sizes.
Features and varieties of the tool
The hinges of the pliers are in special grooves. This allows you to adjust the force with which the lips are squeezed. The ability to reset the diameter does not complicate the work with the tool. Even someone who has never used such a device before will be able to carry out the “tuning”. To rearrange the diameter, it is necessary to spread the handles and reinstall the hinges in the recess.
The design of most varieties of pliers provides for the presence of side cutters. This accessory further expands the possibilities of using the tool. Side cutters can cut cables and wires, as well as quickly get rid of insulating cores. One of the working sides of the pliers has edges. They allow you to cut wire even from hard metals.
Pliers come in two varieties - locksmith and for use in the electrical field. The latter must have a marking that indicates the voltage for which they are designed.
The difference between pliers and pliers
To accurately find out the difference, you need to collect all the differences between pliers and pliers. They boil down to the following points:
- Form. The working surface of each tool is different. For pliers, it is flat, and for pliers it has notches. Of course, there are also combined models of devices on sale, but they are extremely rare and used, since one workspace is usually only additional, and not fully functional.
- Material. Pliers, unlike pliers, allow you to squeeze with much more force. To ensure a long service life of the tool, only high-strength steel is used for its manufacture. Pliers can be made from less durable metal without sacrificing functionality.
- Additional features. Pliers are never with side cutters. Pliers, as a rule, are produced with this cutting device in their design.
Another feature that distinguishes pliers from pliers is that the former allow you to change the gap of the working area, that is, adjust the degree of compression of the part that is being manipulated.
How to choose a quality tool?
Pliers and pliers are two completely different devices, but the recommendations for a successful purchase for them are absolutely identical:
- The swivel type connection should be free of play, and the move should be smooth and soft. If it is impossible to close and open the handles without excessive effort, or, conversely, the sponges move completely freely, it is better to refuse to buy a tool.
- The handles also deserve special attention. They should be made not only of a convenient shape, but also of a material that does not slip. If the tool is planned to be used for electrical work, this part of the fixture necessarily involves insulation.
- When purchasing a tool, be sure to pay attention to how the working surfaces are in contact with each other. If any gaps remain, it will be almost impossible to work with such pliers or pliers.
Not the last role is played by the manufacturer and cost. If you plan to use the tool partly and to perform critical work, it is immediately recommended to purchase a professional model.
Pliers are considered the most common and versatile tool at home or at work. Twisting a nut, cutting off a piece of wire, getting a part out of a hard-to-reach place - we are used to doing all this with the help of such devices, so as not to waste time looking for individual special devices. Many hobbyists call them pliers, which is incorrect. They belong to the same class of hand tools, but their purpose is different.
Varieties of pliers
The detailed composition of such devices consists of cutting or clamping jaws, handles and an axial shaft. Such tools came to us many centuries ago. Since then, their scope has expanded, and the appearance has changed. Each of these devices is characterized by its own design of the sponge part, dimensions and methods of application.
A tool in the form of tongs with long handles, short flat, less often pointed, sponges is called pincers. They are locksmith, blacksmith, electrical (crimping fixtures).
A special type of mites - wire cutters, wire. Their incisors are located in different planes.
Design specifics
Pliers also belong to this type of tool. They are used for their needs by electricians, locksmiths, installers and all home craftsmen. There are terms in the French dictionary from which the name of the most versatile of the pliers comes from. They mean "rod and hinge" and literally describe the design of the device.
This tool combined wire cutters and pliers in one mechanism. Do not use them on hard and large materials: this leads to breakage or deformation of the sponges or handles. Cutting on the working part allows the canvas and 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 incisors is the main thing that distinguishes pliers from pliers. The appearance of the working part for different options is approximately the same.
The transmission of the applied force depends on the overall size of the tool, and other features and characteristics are almost identical.
Different manufacturers introduce various novelties into the structure of the cutting device, special sharpening and hardening to improve the consumer qualities of the product. Definitely choose the leader in this nomination is unrealistic.
Characteristic features of pliers
Still, the difference between pliers and pliers is small. Many distinguish devices with a flat working part into a separate class of tools. By design, they are identical, 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 of 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 nozzles allows you to work with fragile parts.
Very often the same operation is performed by 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 curly surface of the pliers allows you to hold the part more tightly;
- thinner jaws allow pliers to crawl 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, by virtue of their design, compress the object more strongly.
quality requirements
You need to carefully examine how the tool is assembled. You can visually evaluate the design by looking at the closed position of the jaws: equal rectangles indicate a decent quality tool. The allowable gap is a few tenths of a millimeter. This guarantees the full use of the device. Many manufacturers are experimenting with the design of a mobile joint to make it easier to work and extend the operating period.
Metal Features
The service life and performance of work operations depends on the raw materials from which the pliers were made. Any stage of production, both hardening and steel quality, must comply with the technology. The hardness of the metal must be selected to avoid breakage, deformation and chipping. These are usually high carbon steel grades. Regulatory document for pliers, GOST 17438–72 “Pliers. Specifications”, provides answers to any question about these devices.
To prolong the life of the joint, the accuracy of its fit and the physical properties of wear resistance are critical.
Surface treatment
Work with various tools takes place in any weather and in a variety of rooms. Under adverse 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. This is an example of a simple way to avoid exposure to moisture. The hot workpiece is dipped in engine oil and painted with a special varnish, however, after such an operation, the product becomes brittle.
- Chrome treatment gives the desired properties, and in addition, it looks beautiful: chrome plating enhances the steel shine.
- In terms of resistance to mechanical stress, a galvanized product surpasses all previous ones, but has a noticeably less presentable appearance.
Handle qualities
The qualitative result of labor to a large extent depends on comfortable conditions during its implementation. Convenient work with pliers depends as much as possible on the shape and material of their coating. Handles of such devices are of the following categories:
- Simple plastic nozzles for an unpretentious user at a low price. The plastic must be fairly malleable to allow free compression.
- Special ergonomic rubber inserts have tools for frequent and long-term use. They lie comfortably in the hand and do not slip even from sweaty palms. The only requirement is that the material for the overlays 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 cost-effective product is considered to be a hot fit, when plastic insulation is put on the heated ends.
It is important to observe the temperature regime in order to avoid spreading of the plastic. Sometimes iron rivets are inserted as clamps. Such a tool loses its dielectric properties.
Varieties of pliers
Of the entire family of pincer-like devices, they have the most numerous variations. This is due to the variety of areas of application of such equipment. Their areas of application may overlap.
Dielectric Tool
These are ordinary pliers with pronounced electrical insulating properties. With their help, work is carried out without stress relief. 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 target. Such devices are exceptionally light and compact, preventing contact with current-carrying elements in a cramped environment.
Eyelet installer
This name is given to iron or plastic bushings or rings less than seven millimeters in diameter. They reinforce the border around holes in shoes, leather or rubber workwear, thereby preventing the material from tearing. The installation of such fittings requires skill. Now such an operation is performed using grommet pliers.
In everyday life, they are used when installing curtain systems and make this process much less time-consuming.
Combined devices
In this modification, the possibilities of numerous locksmith equipment were mixed. These tools must meet all quality requirements for any kind of sponge-jointed tools.
Due to their versatility, the most common are sliding or adjustable devices with a variable gap between the jaws. In the people they are known as Goebbels pliers, or parrots. This is a kind of mix of pliers and adjustable wrench. Of course, you can’t unmount a rusty connection with it, but for plastic pipes this is the most suitable tool. They are also well suited for unscrewing fasteners with a lost cap or broken edges: even a torn screw will succumb.
When deciding to buy a good tool, it is necessary to determine its main purpose. The requirements that will help you choose a quality tool do not depend on its price and are quite universal:
Which tool is better, you need to determine not by description, but by holding several models in your hands.
Operation Precautions
A mounting tool, like any other, can cause injury during inaccurate work. Therefore, some rules for the use of 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;
- the 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 one-day ones, which can replace good raw materials with worse ones.
Top Models
Among the many manufacturers of products in this segment, there are several that offer reliable, original designs.
Bahco, thanks to the quality of its products and original developments, stands apart in the market for hand tools. The Bahco 2628 model is distinguished by an original hinge: one of the halves is made with an asterisk, and the material in this place is less hard. This provides a moderate backlash, which initially does not exist at all. Another know-how in the return spring on one of the handles. If not needed, it can be turned off.
The Gedore 8245-180 pliers are from a company with a focus on professional power tools. This device also has an original hinged part with a rounded gear pressed into the handle.
Chrome-plated metal withstands loads well, the material of the handles is resistant to dirt.
NWS is a renowned manufacturer of tools for professionals. The quality of the products is evidenced 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 an original design - a transparent insulation with small dots for a better grip on the palm.
Of course, it is not necessary to buy equipment worth tens or hundreds of dollars for everyday use. Cheaper, better quality tools are available everywhere. The main thing is not to make a mistake in choosing, and working with pliers will only bring pleasure.
Pliers, pliers and pliers can be found in any home. At least once everyone had to use them at home or at work. They are used when working with different materials, during the repair of various electrical equipment and machinery. 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 the tool should look like - these are flat sponges that have transverse notches of varying degrees of frequency, swivel joint and handles. Monolithic parts, as a rule, are the working part and handles. This tool is indispensable in plumbing or electrical work, because thanks to them it is possible to hold a part of any shape, 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 well. Pliers are different size 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 be invaluable help in this.
- Tools bent at a certain angle can even get a part from under a covered surface, for example, a screwed circuit board in electronics.
- "Duckbill" are called pliers, which have elongated sponges like tweezers.
- To carry out work with especially delicate materials, special tools are used, as well as silicone nozzles that are worn on conventional models.
The tool differs in addition to the working part and handles. For example, dielectric pliers are applicable in electrical installations. On this type of instrument, 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 tool, then it is strictly forbidden to use these pliers under stress. It is highly likely that this tool belongs to the plumbing business and is not intended for work with electrical equipment.
pliers
This name is borrowed from French, so this product must have come to us from abroad, but so far no one has thought to prove it. The main difference between this spongy tool and pliers is in notched notches, which are convenient when gripping smooth and rounded surfaces, for example, small-diameter pipes.
Pliers in their pure form are no longer available. Often you can find a "mixture" with the same pliers, when the front working surface is flat, and side cutters and wire cutters are placed closer to the hinged part. Such "conveniences", as a rule, are not inherent in pliers. Some models are specially simplified by creating only not one, but two recesses of different diameters for work on capturing rounded surfaces. Other pliers are equipped with an adjustable hinge, which allows you to expand the grip.
Cousins of pliers
Do not forget about the round-nose pliers, which, unlike other similar tools, have sponges with a round section, tapering towards the ends. Imi easy to bend wire, making bends with different radii. The models of this tool are diverse: round-nose pliers are produced with different sizes of jaws, a 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 models of wire cutters resemble pincers. The exception is cutting edges that cut metal of different thicknesses, depending on their capabilities. Nippers, in turn, are divided into end and side. 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.
After all, there are tools only for copper wire, but some can even master nails. Today there is reinforced models, capable of cracking through cable or rebar due to increased cutting edge strength and multiple hinges for greater clamping force.
The difference between pliers and pliers
So, summing up all 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 expense. This in electric mechanisms can be saved on a secondary function, for example, the fifth speed, or an additional nozzle, however, in the manufacture of simple tools, if there is a possibility of saving, then only on the loss of quality. It follows from this that, if your capabilities allow, then it is better to purchase professional tools. The difference between the usual philistine and expensive products will be felt so much that you will quickly come to the conclusion that you should thank yourself for such "waste".
Rate with a glance closure strength of the working surface, only uniform contact is allowed. When compressing and unclenching, a smooth and soft stroke should be felt. Very reliable fixation should be at the handles, because low-quality products “suffer” from slipping, which is inappropriate when working with electricity.
Pliers and pliers are among the most popular tools. This is true for both professionals and home craftsmen. They are indispensable 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 variety of the tool market, it is difficult to imagine a more versatile and necessary thing.
But why do we say they? Is there a difference between pliers and pliers? There is also a lot. It so happened that no one really makes a difference between them. This is not surprising since they are very similar in appearance. But, nevertheless, there are differences and very significant. 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 kind of work are they 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. Mankind has known blacksmith's tongs since time immemorial. Time passed, human society changed, and the instrument 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 necessary and practical.
There are many varieties of pliers and pliers. These include:
- ticks;
- pliers;
- wire cutters;
- round nose pliers;
- pliers.
Each category has "subspecies" that have different sizes of the working surface (sponges), purpose and shape. For example, round-nose pliers are very convenient for cutting cable cores (shown in the photo below). 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 wire cutters. 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 securely fix the part during board soldering, 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 applies to nippers. Different shape of the cutting part, its different size, different purpose. For example, wire cutters for repairing electronic equipment are smaller. For cutting cables, no matter what purpose, they are not suitable. Theoretically, this is possible, but both the worker and the tool are tormented. 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 tool is “visible”: flat jaws with notches, swivel and handles. Pliers are indispensable during any plumbing or electrical work. Due to the flat surface, they hold a part of any shape well. With the help of pliers, you can bend cable cores, wiring, wire and metal. The dimensions of the parts are determined by the dimensions of the pliers themselves (usually do not exceed 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 divided not only by size. For the convenience of the user, manufacturers produce different types of work surface:
- elongated narrow jaws - for the ability to work in places with limited access;
- jaws curved at an angle are designed to work in hard-to-reach places, especially in electronics;
- the so-called "platypus", in fact it is a kind of tweezers, but with a large compression force;
- with special nozzles, for work 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 that the insulation can withstand must be indicated without fail. 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 bench tool and the manufacturer simply does not provide protection for the user from electric current.
There are many varieties of pliers, their type is selected individually, depending on the tasks.
Pliers - practical versatility
Since pliers are "relatives" of 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 recess with notches. It is designed to grip and securely hold round and smooth surfaces. As a rule, pliers have a combined surface of the jaws, 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 recesses 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 into the desired recess. In addition to the degree of compression, this also allows you to adjust the distance between the faces of the jaws, i.e. expands the size range of gripped parts.
In most cases, pliers are equipped with side cutters. They allow you to strip the insulation of the cores and cut the wire or cable cores. In addition, they can have special edges on the front side of the jaws for cutting hard metal wire.
Some manufacturers expand the working area of the pliers by making notches on the handles just behind the swivel. This allows you to capture the part not only with sponges. How necessary and convenient we will leave it to the users' judgment ...
Pliers are also divided into electrical and locksmith. In the first, dielectric handles must be marked up to 1000V.
Pliers and pliers - the difference
It's time to sum it up. So what's the difference between pliers and pliers? Main three:
The shape of the working surface, for pliers it is flat, without a notch. Although there are combined types of tools with notches on the pliers. But this is more the exception than the rule. In addition, pliers are structurally designed for greater compression force. What does it mean? This means that the manufacturer selects the appropriate steel grade for pliers, which has greater strength;
The ability to adjust the gap of the working surface of the jaws and the degree of force of the tool is provided only for pliers (this is achieved by rearranging the hinge);
For pliers, the multifunctionality inherent in pliers is not typical, i.e. the presence of side cutters, special edges for cutting wire, as a rule, is not (again, these possibilities depend on the steel grade and hardening).
- If financial opportunities allow, buy professional pliers and pliers. This is not a whim, the difference between an amateur instrument and a professional instrument, even from leading brands, is very significant. When choosing a power tool, you can save on professional equipment. It's not critical. And in manual very even. It's just a shame when, in the midst of work, you are suddenly left without pliers or after 10 bitten pieces of wire, it will be impossible to use side cutters. The joy of such acquisitions will soon disappear. What can not be said about a professional hand tool. If not a fake, then when used in everyday life, it will last a lifetime.
- Pay attention to the hinge, there should not be any backlash. The move should be soft and smooth. This is a sign of a quality tool.
- With closed jaws of nippers or pliers, there should be no gaps, the surfaces should touch evenly, this is a guarantee of high-quality production and assembly.
- The handles on the handles must sit securely, free sliding, etc. is not allowed. Especially for power tools.
