Pliers, pliers, pliers, wire cutters are representatives of a very diverse group of tools called pliers. Their main difference is in the shape of the working surface, determined by their purpose. These tools are actively used in various fields, they are used by dentists, blacksmiths, and railway workers. In particular, pincers are one of the most ancient tools; they are an integral attribute (along with the hammer) of the Greek god of fire - Hephaestus. Let's start with ticks.
Ticks
Usually this is a tool with relatively long handles and short jaws, which close over a short distance with flat or pointed surfaces. The pliers are intended primarily for gripping parts. Blacksmith tongs hold red-hot metal, they have long handles and various shapes of sponges.Railroad workers have tongs for carrying railway sleepers, as well as for carrying rails.
Tongs for carrying sleepers and rail (ROBEL)
Carpentry (carpentry) tongs pull out nails.
Joiner's (carpenter's) tongs (GEDORE)
Plumbing tongs (pipe) usually have a serrated recess for gripping pipes, inclined jaws and an adjustable hinge mechanism for clamping pipes of different diameters.
Sanitary pliers (STAYER)
The pliers also include a number of electrical installation tools: these are crimp pliers for terminals, pliers for stripping wires, pliers for connectors, pliers for cable glands, current pliers, insulating pliers for replacing fuses, etc.
In general, almost any pliers can be called pincers, for example, pliers, in a simplified way, these are pincers with flat jaws.
Pliers are pliers that have a flat working surface, often with a fine notch. They are used to capture relatively small parts and perform various manipulations with them (bending, biting), often using two tools at once. For different jobs, the shape of the sponges themselves may be different. There are pliers with elongated jaws (long nose pliers, platypuses) and pliers with curved jaws, used when working with parts that are in hard to reach places; pliers with narrow jaws (narrow-nose pliers) used for fine work; pliers with short jaws, providing a large gripping force at the ends of the jaws. Some pliers have pads on the working surface to prevent damage to parts. Often pliers have cutting edges for cutting wire.
Combination pliers, sometimes called pliers, are a tool that includes pliers, has cutting edges for cutting wire and nails, a notch with teeth for gripping pipes, nuts and various cylindrical parts. This is a multifunctional tool, on the one hand, able to help in various situations, on the other hand, special tools cope with specific tasks better. Therefore, combination pliers are a tool for a household tool kit, and not for a professional one.
pliers
Based on the French origin of the name of this tool - pinces-a-tige, pince - clamp and tige - rod, then pliers are a tool for gripping pipes and other cylindrical parts. That is, the main thing in pliers, which determines their name, is a notch with teeth.
Antique pliers with two notched notches,
for large and small diameters
Modern pliers, instead of several notches, have an adjustable hinge for pipes of different sizes.
Adjustable joint pliers (Task Force)
Apparently, pliers differ from plumbing pliers in a smaller size, or you can safely put an equal sign between them.
What many are accustomed to calling pliers, according to GOST 5547-93, are combined pliers. And it turns out that on the one hand, this tool can be defined as pliers with pliers, and on the other hand, pliers with pliers.
wire cutters
Nippers are pliers with a cutting working surface used for cutting wires, nails, fittings. Depending on the position of the cutting edges on the jaws, five main types of wire cutters are distinguished: side cutters (side cutters, diagonal cutters), end cutters (transverse cutters), cable cutters, stripping cutters (they are stripping pliers, see above) and end cutters. More often use side cutters, or side cutters.
When buying wire cutters, pay attention to what kind of material they are intended for cutting, as copper wire cutters may not be able to cope with nails, and the cutting edges will be damaged.
Wire cutters for cutting cables, ropes, fittings, bolts have a particularly strong design, increased hardness of the cutting edges, often several hinged nodes to provide increased compressive strength.

The difference between pliers and pliers is a fact beyond doubt.
Pliers and pliers have some differences.
Common features of tools and design features of pliers
These are hand tools that belong to the class of pliers. Outwardly similar to each other, pliers and pliers often cause confusion, especially among ignorant people. Their construction is simple. These are two metal sponges that perform the main working functions (clamp, hold, bite, etc.), with handles, connected by a hinged mechanism. They have the same simple principle of operation: it is based on the same actions - closing and opening the jaws. The reduced handles provide compression of the sponges, divorced - their unclenching.
The described tools are rightfully considered the most popular. And this statement applies to both professionals and amateurs. Electricians, locksmiths, mechanics, electronics engineers - this is not a complete list of specialists in need of them. And there is no need to talk about domestic orientation.
Pliers are a multifaceted, multifunctional tool. At the same time, when working, they can act as wire cutters and side cutters, pincers and pliers. Some of them are additionally equipped with a screwdriver and an awl located at the ends of the handles. The working area of sponges is equipped with notches. There can also be up to two recesses of different circles at once, the main purpose of which is to capture and hold parts of a round, cylindrical or other shape. The outer side on the sponges is endowed with sharp edges (edges), with which you can bite nails or wire.
And pliers equipped with dielectric handles marked “1000V” are used for electrical work.
There are pliers, where an additional work area is defined under the swivel joint. This means that you can also grab objects with the handles.
On some models, it is possible to adjust the compression force of the jaws, as well as the distance between their faces by occupying a certain position of the hinge in special grooves.
Pliers are made from high quality steel, the processing of which takes place in several stages. And a special anti-corrosion coating is applied to the surface of the finished tool by oxidation or chromium plating.

The variety of pliers, their narrow specialization, differences between tools
Pliers are deprived of everything that is present in pliers. There are no recesses, pointed edges on the lips. Their hinge is fixed.
But there are many of them, and they are designed for different tasks. Only for each operation you have to individually select a certain type.
The main differences are in the width, length and shape of the working jaws. So, when working in places where access is very limited or even difficult to implement, pliers with elongated (long) narrow or curved jaws are used.
There are "platypuses" that provide great compressive strength, required where precise work is especially needed.
And when performing electrical work, you need a tool, the handles of which must be insulated with an indication of the maximum allowable voltage on them.
There are pliers for plumbing work, there is a tool for which special nozzles are used (especially relevant when working with fragile objects), universal pliers are widely used.
However, with all the similarities, there are significant differences between pliers and pliers. Here are the main ones:
- The size (length, width) of the working jaws. For some, their width is standard, the same along the entire length, for others, due to the specificity of the task, the appearance, length and width are completely different.
- The shape of the working surface of the sponges. The presence on its inner part, in addition to notches, of one or even two notches of different sizes and pointed edges for pliers and a completely flat working surface (notches do not count) for pliers.
- Not fixed, and therefore adjustable hinge (pliers) and its rigid fastening (pliers).
- Compression force. For pliers, it is higher, which is achieved by stronger steel.
- The versatility of some and the narrow focus of others.
- Different GOSTs and technical requirements from manufacturers upon release.
Pliers and pliers related to pliers can be found in any home. Each of us at least once used them at home or at work. They are used to work with various materials, in the repair of a variety of electrical equipment and machinery. But, despite their wide distribution and frequent use, rarely anyone calls these tools by their proper names.
pliers- a multifunctional hand tool used for plumbing and electrical work. With it, it is convenient to grab and clamp a variety of parts, regardless of their shape, including cylindrical ones. To capture and turn the latter on the jaws of the pliers, several recesses of various diameters were made with a notch applied to the entire working area. Pliers designed for electrical work are equipped with special insulated handles designed for use under voltage up to 1 thousand volts.
Universal pliers are also produced, combining the functions of pliers, side cutters and cutters for cutting wire of various diameters. For the manufacture of tools used high-quality steel, which has undergone several treatments. A special anti-corrosion coating is applied to the finished tool by chromium plating or oxidation.
Pliers
Pliers- a hand tool used for various plumbing and electrical work. Sponges have a pyramidal shape with a notch applied to flat inner surfaces. The working part of the tool, passing into the handles, moves with the help of a hinge. Pliers are used to grip, bend, and twist all sorts of small pieces of metal, wire, and wire. There are several types of pliers designed for different jobs. 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 (sponges), 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 there are 1-2 pairs of grooves of different diameters with a notch, designed to hold cylindrical parts. The inner side of the pliers has a smooth flat surface with a notched finish that serves to better grip the parts to be held.
Pliers have the same width along the entire length of the jaws. Pliers, depending on their purpose, can have sponges of various lengths, widths and shapes (round-nose pliers, narrow-nose pliers, etc.). Pliers can be a multi-purpose tool that combines the functions of pliers, side cutter and cutter. Pliers are used for any specific action.
Conclusions TheDifference.ru
- Pliers are a multifunctional carpentry and assembly tool, and 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 hinge of the pliers allows you to change the gap of the jaws, and the gap of the jaws of the pliers does not change.
Take it, bite it, pull it! Combination pliers: device, main types and thin choices
Pliers are one of the types of cutting tools used in everyday life with various repairs. With them, you can cut various types of materials without disturbing the structure of the element and achieving good cut quality. Various types of blades are made, which differ in their function. Let's look at their characteristics and applications.
Purpose of the wire mop
Cutters, according to their design, are a universal tool for cutting metal and plastic products that work on the principle of a lever.
They are able to cut wire, electric 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 choosing this type of cutting tool, considering the amount of use?
Design features
Since this tool is used to cut material, it should be selected according to the requirements for this function.
When designing wire cutting tools, there are two main elements:
- The handle providing convenience of work with the tool;
- Cap cutting, also called sponges.
The type of knives is determined by such design parameters as the shape of the cutting edges, the characteristics of their location, 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 or on the same plane with the handle.
- Cutting knives (screws for screws) - used for processing 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 helps protect your hands from electric shock. The design of the handle is distinguished by two types of cabinets: insulated and insulated.
The difference between these types of handles is that the coating of insulated wire blades is made of dielectric, and for insulating materials, it is additionally equipped with cutting blades.
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 tool, there are three types of clamps: ends, side knives and helical blades. All proposed types of pliers can be purchased in the GSM online store.

edge
Pliers
It is used for assembly, in construction, 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 the job they are designed for.
Dielectric tool handles are resistant to high operating voltages.
Side pliers
The worker is tilted relative to the head of the tool. The efficiency of the strongest knives of this type provides additional reinforcement and hardening with high frequency currents.
We produce various models of 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, the heads are inclined to the surface of the handle.
Ensuring the flexibility of the working parts of the tool is characterized by high resistance to the constant operation of monotonous axle loads.
For the manufacture of 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 are capable of withstanding an impact of up to 75kg.
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 your double lever design 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. By watching the video that you present, you can see the information about the cutters that are used to work with the valve.
Types of cutters after use
In terms of use, the following types of pliers can be distinguished:
- pins and reinforcing knives for wire work and fittings;
- Electrical, designed to bite the cable;
- A professional used to carry out cosmetic procedures.
The first type of wire cutter is used for wires without ropes up to 4 mm thick.
T8 steel with a hardness of 42 HRC is used for their production. The handles are 210 mm long, PVC, and have hardened pads on which powder is applied.
Electrical knives are used for cutting insulated aluminum and copper cables with a working diameter of not more than 35 mm.
For heat treated stainless steel cutting edges. Knives are made by forging steel, which falls from the height of a hammer.
The strength of the cutting edges ensures that the cable is cut without significant shear deformation and internal wires.
Products are equipped with fiberglass and rubber handles.
Professional pliers are a tool for performing beauty treatments such as manicures and pedicures. They are small and designed to remove the shell. For the manufacture of professional pliers, strong stainless steel is used, which is used to make surgical instruments.
The metal is subjected to a special heat treatment, which makes it hardness up to 50 HRC.
Cutting the edges of products is a high-quality enrichment that ensures the durability of the tool.
Pliers
Some types of tools simply must be in any house or apartment, even where it would seem that they are not needed. One such tool is a pair of pliers.
Pliers are different from pliers
It is a versatile household helper that can be used to hold, pull, bite and crimp, 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 of hand tools. Pliers came from pliers, because their device is almost exactly the same - for example, two connected halves (the working part and the handle) are connected by a special hinge, so this method of fastening and arranging pliers classified the tool as pliers-hinged tools.
In order to choose a tool, the first thing to do is to decide on the type of pliers, since for a long time of their existence, several varieties have appeared.
Types and differences of pliers
The most popular today, on the tool market, are electrician's pliers (or combined pliers).
This type is made of electric tool steel, and the working part of such pliers is hardened in oil. Of the additional distinguishing 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, very useful qualities and properties of the tool are revealed. So, it is ideal for working in electrical networks - during the laying of cable channels, for laying wiring, for grabbing and cutting wires, for bending wire or crimping sleeves.
Adjustable pliers are also a fairly common type of tool that is made from durable, hardened steel. The surface of these pliers has a galvanized coating, and the tool itself is perfect for assembly production, as well as 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.
Such pliers are made of heavy-duty steel, and their feature is versatility and compactness. So, this tool combines several tools at once (a saw, scissors, a ruler, a corkscrew, etc.). Therefore, such a tool will be extremely convenient for the repair or installation of objects.
How to choose pliers?
To choose and buy pliers correctly, before you 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 material for making pliers;
- R dimensions and parameters of pliers;
- d additional possibilities.
Plier material. Absolutely, all types of pliers must be made of high quality material - tool steel, chrome vanadium or chromium molybdenum steel can be used for this, and also, the design of the pliers can be combined.
The jaws of the tool can be made of titanium alloy, or hardened steel (if it is an electrician's pliers, hardened under high-frequency current). As the material of the handles, polyvinyl chloride or dielectric plastic, rubber, and so on are most often used. Among other things, pliers can be additionally coated with an anti-corrosion varnish layer.
Plier sizes.
A rather important characteristic is the size of the tool. So, the standard for the manufacture of pliers involves the manufacture of tools with dimensions of 130, 160, 180 and 200 mm. There are exceptions, during which pliers are made larger or smaller. The most widely used are pliers, with sizes of 160, 180 and 200 mm. An important feature is also the hardness of the material from which the pliers are made.
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 bite the wire.
Such edges are hardened separately to 62 HRC and above. 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 collaborating with them for a person they consider to be 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 articulated jaw tools with a flat work surface, as the name suggests. There are often bumps of different sizes on this surface.
Pliers and 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 a large gripping force at the ends of the pliers. In order not to damage 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, recesses have:
- at least two notches for gripping 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 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 allowable voltage. Without specifying these data, it is strictly forbidden to work with wires and live devices; such tools do not provide user protection from the current.
In addition, both tools:
- They are made of high quality steel with anti-corrosion coating.
- They have courses and a working area - sponges.
- Enable capture of various objects and details.
The main differences between the instruments are in the configuration of the jaw.
In addition, the loops of the pliers are not fixed, which allows you to greatly adjust the size of the sponge. Apparently, pliers are much more versatile and can be replaced with multiple tools at once, while clamps have a much narrower reach.
In addition to pliers and pliers on tools with a jaw:
- round pliers;
- ticks;
- wire cutters.
Each has a common function, but several different applications and configurations.
If you decide to lay a roof covering, then you will be able to cope with this on your own, because the light weight of euroslate sheets allows you to transport and assemble the material without special equipment and construction skills.
It can be used in the construction of the roof of houses, cottages, baths, gazebos and other outbuildings.
Before starting installation work, it is recommended to read the instructions supplied by the manufacturer complete with ondulin and its accessories. In addition, the instruction is endowed with 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 observed during the installation of 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 the case of installation by a construction team, the customer must also be aware of the main stages of work in order to control the quality of the roofing installation.
List of rules for the installation of ondulin roofing
Each stage of work must be performed qualitatively, in compliance with the designated rules. So, an incorrect calculation of the lathing step 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 on the roof - properties and installation”).
As a rule, the ondulin installation instructions also involve minor deviations or actions at the discretion of the developer, however, with insufficient experience in such construction, it is better to abandon amateur activities.
Features of the installation technique of ondulin flooring
Below are detailed instructions for laying the ondulin coating.
At the request of the owner of the house, 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 is covered with the top sheet from above, while the overlap is taken into account for each layer of material. See also: "Do-it-yourself ondulin roofing installation scheme - a step-by-step guide."
How to properly lay ondulin so that the roof does not leak, details on 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 the waves of the bottom sheet, and the top roof covering with ondulin is mounted on it, taking into account the allowance for overlaps.
In the process of laying roofing sheets and mounting 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 (see also: "Andulin roof - varieties of material").
It should be noted that in some cases, developers mount a metal one instead of a wooden crate, then to fix the ondulin flooring, you need to purchase a set of special self-tapping screws, and not nails, as in the classic version.
Thus, the installation of a roof using euroslate will not cause any special problems if the rules listed above are observed, and a new roof made of light, but durable and reliable ondulin, with the correct implementation of the technology, will serve for many years.

Perhaps it is impossible to imagine a more popular hand tool in everyday life and professional activities than pliers and pliers. The difference between them is quite significant. And although some people confuse these two types of instruments because of their appearance, however, the quality and even the standards of workmanship in both cases are not the same. The difference between pliers and pliers should be considered by all craftsmen when choosing them. There is a specific type of tool for everyone.
General concept of a pliers tool
To understand the differences between pliers and pliers, you should delve into their device. Both of these varieties belong to the class of pliers. This type of improvised means was used by ancient masters.
This class of tool includes various pliers, round-nose pliers, wire cutters, pliers, pincers. Each of these species has its own purpose. Pliers and pliers, the difference (photo below) between which every master must understand, have their own subspecies.
Basically, they differ in the size of the sponges, which makes it possible to use such improvised tools for work of any complexity. Each type of pliers is designed to perform a certain type of operation.
For electrical work, it is necessary to choose a special type of equipment. Its handles are insulated with a special material, which most often withstands a voltage of 1 kV. Plumbers and locksmiths can choose simple varieties of pliers and pliers.
Characteristics of pliers
The difference between pliers and pliers (the photo is presented to your attention below) is easier to understand by considering the characteristics of each of these improvised tools.
Special attention deserves their appearance and application in the work of masters. The length of the pliers is in the range from 12.5 to 20 cm.
Types of pliers
Considering such varieties of pliers as pliers and pliers, it will not be difficult to understand how they differ. In order not to confuse these two hand tools, their subspecies should be described. Pliers include several types of devices. They differ in working surface.
If the jaws are elongated, this will allow you to work in hard-to-reach places, to reach the necessary wires or parts. If they are not only elongated, but also curved, this is most likely a tool for electricians. Such devices are used in work when it is extremely difficult to reach the object. The bend radius can be 40 or 60 degrees.
Platypuses are similar to tweezers, only they have more compressive strength. Pliers and pliers, the difference between which in some respect affects the work of the master, may have different nozzles. This will allow you to skillfully handle fragile materials.
Characteristics of pliers
Pliers and pliers are the same type of tool and can be small, medium or large. Their scope is similar. They are used in plumbing, assembly, electrical, plumbing work, etc.
The surface of the jaws of the pliers has a notch. This allows you to hold round smooth parts. Most often, the surface in them is combined. There is a flat area, as well as recesses of different diameters.
Pliers and pliers, the difference between which lies not only in the shape of the surface of the jaws, also differ in capabilities. This increases the range of operations performed by the wizard.
Pliers allow you to adjust the compression force, as well as the distance between the surfaces of the jaws. Therefore, such a tool is suitable for parts of various diameters.
Additional features of pliers
Pliers and pliers, the difference between which lies in functionality, should be selected in accordance with the type of activity of the master. The electrician and plumber must select the appropriate type of hand tool.
Based on the needs of a specialist who uses pliers, the latter may have various additional features. Many manufacturers supply their products with side cutters. This device allows you to strip the insulation from the cable, cut the wire.
Sometimes there is a special edge on the front side of the pliers that allows you to cut very strong wire.
In other cases, the working area of the pliers extends beyond the swivel. On the handles of such models there are serifs that allow you to hold the workpiece not only with sponges. Not every master is comfortable with this, but it depends on personal preferences.
Characteristic differences
Pliers and pliers have a lot of similarities. What is the difference between these two similar tools should be considered in more detail.
The very first thing that can be noted when studying these products is the difference in the shape of the sponges. Their inner surface at the pliers has recesses to hold round parts. Pliers also have a flat surface with notches for better grip on the surface of the part.
The pliers have the same width of the jaws along the entire length. Pliers can have different lengths and widths. The choice depends on the purpose of the tool.
Main differences
Pliers and pliers small, medium or large have three main differences.
- Sponge surface shape. For pliers, it is even, and for pliers - with a notch. In the second case, the tool is designed for stronger types of steels during operation.
- Possibility of adjustment. It is possible to select the required gap of the working surface and the compression force only in the case of pliers. Therefore, this feature should be taken into account when choosing improvised means.
- Versatility and additional functions (side cutter, special edges) are inherent only to pliers. However, in the case of simple work, for ease of operation, you must opt for ordinary pliers.
How to choose a tool
Pliers and pliers, the difference between which determines the scope of their application, it is better to choose professional ones. These are the most durable products that will serve their owner for many years. Cheap models sometimes quickly lose their functionality or even fail. Therefore, when choosing a tool, it is better not to save.
A quality product can be identified by looking at the hinge department. There should be no backlashes, and the course of the handles must be smooth. When connecting the jaws, there should be no gaps, distortions. In a quality tool, they close evenly.
It is extremely important, especially for electrical work, that the handles sit tightly on the base and do not fidget. This will allow you to work with improvised means safely, without fear of electric shock.
Having become acquainted with the distinctive features of products such as pliers and pliers, any master will understand their difference from each other. In accordance with the required type of work, hand tools are also selected. It differs in size, shape, additional features and functionality. Each specialist must take into account the features of a hand tool and purchase high-quality copies. This will guarantee a long service life of pliers and pliers of any configuration.
In this article we will look at what types of pliers exist and what is important - how to choose them correctly.
But judging by the number of questions, many people do not know the differences between pliers and pliers. And we need to understand this, because the tools were created for different things! Their thoughtless use does not improve the result of labor.
There will always be craftsmen hammering nails with adjustable wrenches. But I believe that our audience is inquisitive and skillful people. Therefore, let's figure it out.
Are these pliers or pliers?
Mounting pliers and pliers have two movable parts, fastened together by a hinge. Therefore, both classes of tools belong to the category of pliers.
Scope of SGI:
- mounting
- plumbing work
- electric installation work
With these tools, you can remove the nail from the plank, tighten the nut, and replace the faucet box in the bathroom. But for work with electricity, only dielectric shgi are suitable, which can withstand a certain voltage without risk to the health of the worker.
Housing materials
Pliers and pliers are made of tool steel grades CS45, CS55, chrome-vanadium. The latter material is used less frequently and is more expensive, but the best in hardness and wear resistance. CS55 follows right behind chrome vanadium, while CS45 is used for budget hand tools.
An important quality parameter of a material is its hardness, measured on the Rockwell scale. Designated by number and signature "HRC".
Then the metal is processed by volumetric hardening and covered with a protective layer using:
- oxidation
- chrome tinting
- phosphating
Both classes of tools have two types of handles:
- One-component - entirely plastic or rubber-coated. Suitable for use in aggressive environments. Plastic handles are attached with glue, in some cases the handles can turn or fly off - if they are poorly glued. Plastic is also not without drawbacks - it slips out of the palm when working with gloves. Rubberized handles are held tenaciously, pleasantly felt in the hand, but are easier to scratch and cut in the process.
- Two-component handles - a base made of conventional or impact-resistant plastic plus a rubber coating. Plastic gives strength, including when falling from a height, and the rubber coating eliminates slipping of the handles in the palm of your hand.
So, with the general details it is clear. What is the difference between pliers and pliers?
Let's talk about this in more detail.
Pliers are a tool with flat jaw surfaces, hence its name. It is necessary for uniform gripping of workpieces.
The clamping surfaces of the pliers have only teeth and sometimes cutting edges, but no notches. Ideal for holding small parts, wires and fasteners.
You assemble and repair electronics, mechanisms, up to watches - you need pliers.
Another option in this group is the bending of wires and metal plates. Smooth surfaces without recesses allow you to capture the workpiece over the entire area without additional damage to the materials.
Later we will take a closer look at the types of special pliers for precision work, but first we will deal with pliers.
Pliers are a multifunctional tool and have a clear focus for power work. The word itself is French, it can be translated as "rod clamp".
Assembly and jewelry work cannot be called the strengths of pliers.
The fact is that the tool is made with combined jaws: there are recesses for gripping cylindrical parts: rods, thick wire, nails, screws.
There are also flat clamping surfaces, they are always made with a serrated notch, which increases the clamping force of the jaws. Therefore, pliers can capture parts, but you risk damaging the workpiece. It is more logical to use pliers for roughing.
Be careful, pliers are often confused with combined-type pliers: the latter can also have an oval notch, but are additionally equipped with a cutting edge for separating wire and fasteners. Also, in the hinge area, there may be an additional recess for cutting the same wire.
A number of models of pliers are produced with a sliding hinge - in order to spread the jaws wider and capture workpieces of a larger diameter.
Since pliers are more powerful in their purpose than pliers, they use a material of greater strength and hardening. If the hardness rate for pliers fluctuates around 47 HRC, then for pliers it reaches 53 HRC.
Pliers combine the functions of several tools, so they are more often bought. However, pliers are indispensable for precision work and work in confined spaces. It is convenient to keep both at home.
How to use pliers:
- The pliers must be lubricated, otherwise they will not move, or the lips will come together sharply, jerkily - this way you can hurt your hand.
- Choose pliers so that when closing, they do not pinch your fingers.
- Clamp both flat and cylindrical parts with pliers.
- When working, do not push, but pull the handles of the pliers.
Types of pliers
The assortment of VIRA tools includes a number of pliers for assembling household appliances, electronics, and in some cases it is simply convenient to use these products in small niches in walls, when working in recesses and holes in the ceiling, floor.
We openly indicate the parameters of our tools on the site, and what materials we use for them.
Long nose pliers. They perform similar functions to pliers, but due to the elongated and narrower gripping parts with a serrated notch (already 10 mm), they make it easy to grip screws and small parts of the assembly. The cutting edges are designed to work with wires and wire. Steel material CS55.
A variant of the modified tool with curved jaws - platypus pliers. The good thing about this tool is that it allows you to get to wires and fasteners in curved or angled spaces. Both serrated clamping surfaces and cutting edges are available here. Again, they are more suitable for wire and wire, not nails. Steel material CS55.
Why do we need round-nose pliers: for curly bending of wire. Cone-shaped jaws allow you to bend workpieces with a radius of up to 0.6 mm. Used mainly by jewelry manufacturers. The working part is made of high carbon steel CS55.
All precision pliers are produced with two-component handles. We use impact-resistant ABS plastic as a basis for them, and additional comfort is achieved through TPR rubber inserts.
This is a rough and elastic material that lies softly in the hand, while the tool does not slip in the palm of your hand even when working in the rain.
Another representative of the SHGI VIRA group is side cutters. The tool is specially designed for cutting wires, as it has only a cutting edge, without clamping surfaces. The key property of a tool is its cutting properties. A great option for an electrician, installer and repairman.
Many people are interested in the difference between wire cutters and side cutters. One could write a separate note about this, but in short, side cutters are a kind of ticks.
Metal processing
To protect VIRA pliers, we use metal oxidation or burnishing. This helps protect the instrument from moisture and rust. With this treatment, pliers can last 5 years longer.
quality standard
All VIRA SGIs comply with the requirements of the German Geprüfte Sicherheit (GS) standard. This sign denotes products that meet the safety and quality of production.
How to use pliers:
- Check tool lubrication. It gets to the store already well lubricated, but it is better to make sure of this. Without lubrication, the clamping surfaces will not move and the pliers will rust.
- Pliers are not designed for clamping large parts. Use the tool for medium and small workpieces.
- Tools do not involve aggressive work. Excessive pressure on the handles spoils the condition of the cutting edges, teeth of the clamping surfaces over time. In addition, the appearance of the machined parts suffers.
- Grab the flat parts of the workpieces with pliers.
- When working on live parts, hold only the handles of the pliers (only dielectric pliers are suitable for this)
- Pliers are not suitable for cutting hard materials such as steel.
How to choose pliers
- Check hinge.
Pliers should not “walk” too much at the place where the moving parts are fastened. Take the tool in your hands horizontally, with the sponges away from you and try to shake the pliers by the handles up and down. A joint in a hinge without much play indicates the quality of the assembly of the tool. Strong backlash - the moving parts fit poorly.
- Check the convergence of the jaws
The clamping surfaces of the tool must be sufficiently pressed against each other during mixing. This is important for tools used in precision work, because if the jaws do not come together well, small parts and fasteners will fall out and not be held.
- Handle comfort
Make sure that they are securely held and do not fly off, pleasant to your hand, do not slip in the palm of your hand. If the handles scratch your fingers and hand at least a little, then with constant work, calluses and scratches await you.
I hope that now you know the difference between pliers and pliers and can make an independent choice in favor of a tool that suits your own purposes. In addition, now you know what types of pliers exist and what they are for.
