Combination pliers sale. What they consist of, what they look like and what makes good pliers different. There are several types of pliers that differ in the type of working jaws.

Pliers are the most popular tool in the household. Although professional craftsmen also cannot do without this versatile tool. Mechanics, locksmiths, electricians and other workers cannot do without them. With a large assortment of tools in the trading network, there is probably no more necessary and universal thing.

Consider the existing types of pliers, their design features and differences from other similar tools, how to use them correctly, and how to make the right choice when purchasing.

Design features

Pliers refer to a pliers tool used for various electrical work, plumbing and other work. Pliers can grip parts of different shapes, as well as thin pipes.

This product combines the construction of two tools: nippers and pliers. This versatile device is very convenient when doing small household chores for a home craftsman. Pliers usually perform cutting of wires only from soft metal, since the cutting edges are deformed from the hard material and quickly become unusable.

On the jaws of the tool, a special notch is applied, the shape and size of which determines the reliability of holding the captured part. There is also a notch on the other side of the hinge axis, which is closer to the handles. This makes it possible to grip the part with either side of the pliers of your choice. The geometric shape of such a tool in different versions is practically the same, except for the sizes. The longer the product, the more force you can create on the jaws. All other parameters and sizes are slightly different.

Sharpening of the cutting parts plays an important role. While improving the tool, manufacturers create various new qualities: sharpen sharp edges at special angles, harden them in a special way, etc.

The assembly of a product largely determines its quality. Ideally, there should be no gaps and backlash in the pivot joint, and the pliers handles should be moved apart without much effort with the fingers of one hand. A slight gap between the jaws in their compressed state (a few tenths of a millimeter) is allowed.

Good quality pledge

To indirectly evaluate this tool for quality, it is enough to look at the end of the compressed jaws. If you can see two equal rectangles of the correct shape, then most likely you are dealing with a quality tool. During manufacturing, this feature is practically not paid attention to, and the correctness of the shape of the sponges indicates the accuracy of the assembly. Well-known manufacturers of high-quality tools create an original design of the hinge, which makes it possible to extend its service life.

Metal

Steel for the manufacture of pliers determines their operational capabilities. During manufacture at the plant, the composition of the material must be maintained, and a special heat treatment technology must be used to impart the required hardness and strength to the elements of the tool. In order for the swivel joint to serve for a long time, the hardness of the axle and the outer part must be equal. Cutting edges and jaws of expensive products, in addition to heat treatment, are usually additionally hardened with high-frequency currents.

Coating

Another important factor is the application of a special composition to the surface of the tool to prevent corrosion. Otherwise, after moisture gets on the tool, they will quickly rust and become unusable. A simple coating is burnishing the surface, which consists in placing the part in hot oil steam, followed by coating with a protective varnish.

This treatment is also called oxidation. This is insufficiently high-quality protection when working with high humidity, therefore such a tool is only used for indoor work. In order to be able to work outdoors without problems, a higher quality finish, such as chrome plating, is necessary. It gives a beautiful steel sheen, especially if the finish is thoroughly polished.

Zinc-coated pliers are quite rare. This coating is practically not inferior to the previous type, and even surpasses it in resistance to mechanical shock. However, in appearance, the zinc coating is clearly inferior.

Hand grips

To ensure the convenience of working with pliers, the handles of the tool are enclosed in plastic. There are several types of handle insulation:

Regular... Made only of plastic that does not contain substances harmful to humans. They have a low cost.
Ergonomic equipped with rubber pads. Rubber elements increase the convenience of work, however, in case of poor-quality rubber during contact with the palm, a person may experience allergies.
Electrical insulating, made of tougher plastic for high-quality electrical insulation, ensuring the safety of the worker when working up to 1000 V.

An important factor is the secure fixation of the overlays. On low-quality Chinese pliers, plastic handles can turn and slide off the tool, which greatly complicates their use. A simple way to attach plastic handles is to glue them. A more modern method of fixation is the “hot” fit of the handles, that is, they are put on in a hot state, when they cool down, their temperature shrinkage occurs, and they are securely fixed on the instrument. In rare cases, fastening of handles with metal pins is used.

Views

There are several types of pliers, each of which is designed to perform specific types of work.

Dielectric pliers

In terms of functionality and appearance, such a tool is similar to conventional combined pliers, but it has special insulating handles for performing electrical work on connecting live electrical equipment, replacing metering devices (with permission and certain skills).

Soft handles with a comfortable shape allow you to safely and comfortably carry out all the necessary work. The plastic of the handles can be reinforced with fiberglass for added strength. Insulation material does not allow electric shock to a person. The surface of the handles is ribbed, which prevents the hands from slipping during operation. The jaws of the tool are specially serrated for a secure grip. The weight and overall dimensions of the tool are small, working with it for a long time does not create much fatigue.

Luvers

This is a common DIY tool. In the manufacture of curtains and curtains, a plastic or metal ring with a diameter of up to 7 mm is often used, which is called an eyelet. Thanks to specially developed eyelet pliers, installation is very quick. This procedure has been greatly simplified: it is enough to apply a few forces on the handles, and the rings are fully fixed to the material.

Combined pliers

Such pliers can perform several functions of various plumbing fixtures and tools: side cutters, wire cutters, pliers, etc. They, like other models, are manufactured from durable carbon steel, and the sharp edges are hardened to increase their service life. Metal elements are coated with a special coating and polished.

There are special versions of combined pliers, which can even grip pipes, since they have the ability to adjust the amount of opening of the jaws. They are also called pipe or adjustable. They are also used to grip various large parts, thick cables, as a wrench.

Pliers

This is one of the varieties of pliers that have flat jaws.

By the name of this tool, the shape of their lips becomes clear. They are notched, have handles and a swivel joint. Pliers are a handy tool for a variety of electrical and plumbing work. With their flat jaws, it is convenient to hold parts of various shapes. Pliers are usually used to bend conductors of wires, cables, as well as metal and steel wire.

The dimensions of the parts that can be clamped with pliers are determined by the dimensions of the tool itself (usually no more than 200 mm). Quite often, such a tool is used instead of a wrench, since the flat jaws repeat the edges of the wrench. Of course, pliers cannot completely replace a wrench, but in extreme cases, when the necessary tool is not available, they fully justify themselves.

There are several types of pliers that differ in the type of working jaws:

Long narrow jaws for work in hard-to-reach places.

Curved lips, serving also for hard-to-reach places, or when installing electronic equipment.

Round nose pliers, are used mainly for electrical work.

"Platypuses". In fact, they are analogous to tweezers, with a greater compression force.

With various attachments for the convenience of working with delicate and fragile materials.

To use the pliers for live electrical installations, there are special insulated models. The plastic handles indicate the highest voltage value for which the insulation is designed. Most often, this value does not exceed 1000 volts. If this parameter is not specified, then the use of such a tool for working under voltage is strictly prohibited. Most likely, these are ordinary pliers, not designed to protect a person from electric shock.

Many people are mistaken in the belief that pliers and pliers are one and the same thing. However, these tools have several differences:

The shape of the surface of the jaws of the pliers is flat and does not have a recess.
Compression force. By design, the pliers are designed for high compressive force. Accordingly, more durable steel is used for them.
The ability to adjust the size of the opening of the jaws is available only with pliers (by moving the hinge).
Functionality. Pliers are less functional as they do not have side cutting edges.

If you have enough money, it is better to purchase a professional model of the tool, since it is much better and more reliable in operation. If your purchase does not turn out to be a fake, then such a tool will be enough for almost a lifetime.
A backlash in the hinge indicates a low quality of the product, as well as biting and seizing when moving the lips apart. It is better to refuse such a tool.
Do not move the plastic handles on the tool, especially if they are dielectric pliers.
Gaps in the closed jaws, and their uneven fit, also indicate poor product quality.

Pliers - this is the name of a tool belonging to the hinged-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.
The 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 are related to fitter's 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 other varieties of them, designed for a certain kind of work. For example, "platypuses" are pliers with elongated lips, reminiscent of 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 part, confidently grip cylindrical surfaces, nuts, bolts or studs.

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

This tool uses chrome vanadium and chrome molybdenum steel, making 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.

The pliers of some models 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 parts that are much larger than standard tools are capable of gripping.

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 taken into account 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 many centuries. It is not yet known exactly when the instrument in question was manufactured. There are different types of pliers:

Ticks.
Classic design.
Round nose pliers.
Pliers.
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 when using round-nose pliers. The curved conical shape of the work 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:

The jaws are flat and have notches applied. In this case, the size of the sponges can vary significantly.
The pliers are connected using a hinged design.
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 long-term operation. If the maximum voltage is not indicated, then the use of the tool is strictly prohibited.

There are two main groups of pliers:

The classification is also carried out according to the size of the product. 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.

Difference of 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 how pliers differ from pliers, it is worth noting that the first version of the design is multifunctional, the other is suitable for carrying out 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.

Adjustment of 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. The features of this proposal include the following points:

Many models are also equipped with side cutters. They are used for stripping and cutting cable cores.

There are models with extended working heat with pliers. For this, the notches are made immediately after the swivel joint. Due to this change, the gripping of the part is carried out not only with jaws, the scope of the tool is significantly expanded.

In conclusion, we note that a fairly large number of different sets are on sale. It is not recommended to purchase kits, as in most cases cheap items are included in their kit. Your best bet is to pick up the tools individually and build your own set.

In a home workshop, there are pliers and pliers, or, in extreme cases, one of them. This is a tool that is difficult to do without when performing virtually any type of work, both locksmith and electrical, mechanical, repair, etc.

Many people think of pliers as different names for the same tool, but this is not at all the case. They have different functions, moreover, state standards have different requirements for them.

Types of pliers

The first hinge-pliers tool can be considered a blacksmith's pliers, or, perhaps, a similar device with which something was pulled out of the fire. The names of the authors of such a valuable invention, like its date, are hidden in the mists of time.

There are five main types of pliers. It:

Ticks. They pull out nails, hold metal blanks.
Nippers. This tool is designed, as the name suggests, to cut through something, such as a wire.
Round nose pliers. Convenient for working with cable conductors.
Pliers. Clamping of any materials, bending, holding, etc. are used.
Pliers. They are used for the same as the pliers, plus they have many additional functions.

The classification is rather arbitrary, because, if desired, it can include garden shears, shears for cutting tin, etc. In addition, species necessarily have subspecies, and so on ad infinitum.

Pliers, their features and application

To understand how pliers differ from pliers, it is enough to familiarize yourself with the structure of both. The pliers are pretty simple. As you would expect, this is a pair of flat lips, notches on them, handles and a hinge as a connection. It is convenient to work with such a tool with wire, wire, sheet metal, hold metal, wooden or plastic parts suitable for exchange, even tighten nuts if there is no wrench at hand.

Pliers come in different sizes, and most importantly - with different lip shapes. They can be elongated, narrow, curved in any direction. It all depends on the area of application. For example, pliers with curved or thin long lips are highly valued by radio technicians and electricians, since they can easily reach hard-to-reach places with such a tool. Pliers are practically not available without electrical insulation on the handles. Usually, the insulating layer indicates how much voltage it can withstand.

Pliers: multitasking and versatility

The difference between pliers and pliers is fundamental in terms of functionality. Pliers are pliers plus side cutters, cutters for cutting wire or wires of various diameters, an additional grip placed after the swivel connection.

Side cutters can cut wires and wires, hold round objects of various diameters well in the recesses, etc. There are pliers modifications, in which it is possible to regulate the compression force by moving the pivot joint rod into special grooves.

Several conclusions should be drawn from what has been written. If no one confuses the pliers or pliers, then not everyone can see the difference between the pliers and pliers. You just need to remember one thing - if the lips are only with notches - these are pliers. If not only - pliers.

Pliers

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

Pliers

Universal pliers are also available, combining the functions of pliers, side cutters and cutters for cutting wires of various diameters. For the manufacture of tools, high quality is used, which has undergone several treatments. A special anti-corrosion coating is applied to the finished tool by chromium 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 inner surfaces. The working part of the tool, passing into the handles, moves with a hinge. Pliers are used to grip, bend and twist all kinds of small pieces of metal, wires and wires. There are several types of pliers for different jobs. They differ in the length and width of the jaws. The pliers are also equipped with insulating handles for live work.

Pliers

Differences

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

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

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

Conclusions site

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