In every house, regardless of its inhabitants, there is a certain set of tools that will always come in handy. One of these tools is a pair of pliers or pliers. Despite their superficial similarities, these two instruments have some differences. Both belong to a large group of pliers.
A story of this kind began long before our era: it is enough to remember the ancient Greek god-blacksmith Hephaestus, who was portrayed 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 be used as a bending tool only in some cases, since the width of the lips does not exceed 20 cm.
There are several types of pliers with different types of lips.
The latter are:
- Elongated, narrow: suitable for small objects or hard-to-reach places. They have little compression force.
- Narrow curved: mainly used in electronics for access to the most "inaccessible" places, for example, under a board.
- "Platypus": These are pliers with strongly elongated lips. In terms of functionality, they are similar to tweezers, but they allow you to squeeze the part more.
For work with fragile materials, use special nozzles with surface protection or without notches. For work with electricity, pliers with insulation on the handles are used: they must indicate the maximum current value. Most often, such instruments can withstand up to 1000 V.
Note: it is forbidden to use ordinary pliers when working with electricity, as the handles are not protected.
What are pliers
Unlike pliers, the jaws of the pliers have both a flat part and a small notch, which allows you to grip a part with an excessively smooth surface more firmly. This makes the tool more popular and versatile. Some models have two grooves 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 the nuts, but this should only be done in extreme cases, as the edges can be ripped off.
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 - with recesses for some parts;
- The specialization of pliers is narrower: they are intended only for holding the part, all other functions (cutting, tightening the bolts) are not their "native", which can lead to problems. The pliers are more functional: they can cut wire and metal, hold the parts more firmly;
- For the manufacture of pliers, more durable steel is used, since the tool is designed for a high compression force;
- The pliers have a wider gripping range due to the presence of a movable connecting joint. This helps expand the use of the tool;
- Pliers are often more expensive because they are more functional.
Note: you should not save on the purchase: it is better to choose high-quality models that will serve for several years than to regularly change them.
To make the right choice, you should pay attention to the following:
- the sponges should be intact, fit snugly to each other, not dangle, not have gaps or crevices;
- 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 an instrument, it is desirable to be able to test it, hold it and adapt.
Many people think that pliers and pliers are one and the same, but this is not the case, although in some situations they can replace each other. Both tools, while performing similar functions, have a number of differences worth keeping in mind. When choosing a model, it is important to clearly understand their purpose so as not to buy a useless thing, it is also recommended to consider the models in the pictures in advance.

Pliers are an essential part of any craftsman, be it a professional locksmith, installer, plumber or electrician.
They can grip, hold, bend and twist various objects, including those under voltage (when using dielectric models).
How to choose pliers
- The first thing to consider when choosing a tool is for what purpose it is needed. If the product is required as a working manual tool of the master, then their professional types should be considered.
Varieties intended for domestic purposes are not suitable for constant use and increased loads.
- The second criterion is the manufacturer. A high quality tool, if properly used, can last for many years.
- It is necessary to pay attention to the performance and functionality of the pliers. Electricians should definitely choose electrically insulated models. It is desirable for professionals to have several types of products for different types of operations.
- It is advisable to choose the handles of the instruments that are ergonomic, following the anatomical shape of the hands. In the case of prolonged use during a work shift, the foreman's hands will get less tired.
- When choosing hand tools, color matters, as black pliers, for example, are difficult to find in dark rooms.
Therefore, it is advisable to give preference to models with a brightly coated handle. Nowadays, you can even buy pliers with fluorescent coated handles that will glow in the dark.
- When choosing a product, you need to check it by squeezing the handles. In this case, the jaws of the tool should close tightly and evenly.
- The desire to save money on hand tools and the purchase of goods not from authorized dealers may entail the purchase of non-original products.
This will be a waste of money as it won't last long. A counterfeit will not meet security requirements.
- It does not matter what kind of decorative coating the product body has (chrome, nickel, etc.), that is, the external beauty of the instrument. This has absolutely no effect on the functionality and other essential characteristics of the product.
- The presence of additional functions in highly specialized models (most likely, they will not be useful).
- The best combination pliers are Knipex. Their manufacturer is a German company that produces high quality hand tools according to VDE standards.
Pliers from this company can bite through hard wire. They are the most expensive, yet durable, ergonomic and highly efficient.
- Pliers for professionals under the brand name Bahco (Sweden) are among the best and are produced in factories in western Europe and the USA.
Products comply with ISO standard. All Bahco combination products are electrically insulated.
- Brand tools IRWIN (USA) are also professional and of high quality.
The electrically insulated combination pliers from this manufacturer are VDE compliant, but have a shorter service life than the above models.
The combination product has wire cutters in the middle and on the sides (side slots in the hinge area). In addition, the pliers have a serrated notch for gripping small diameter rounded objects.
This model is designed primarily for gripping and manipulating wires and cylindrical objects. Modern pliers can be equipped with a return spring or adjustable joint for adjusting to different pipe sizes.
Pros:
- multifunctionality,
- versatility.
Minus: most often household orientation.
- Corresponding company products BeadSmith is a high quality silicone grip that is non-slip and fits well in the hand.
They are ideal for straightening wires and working with brittle material, but they are quite expensive.
- Model HTP-18 with nylon pads from the firm Micron is the most popular in Russia due to its excellent combination of price and quality. It has high functionality despite its budgetary cost.
- Tools with nylon tips manufacturing Beadalon(USA) are functional and easy to use, but their quality is no better than that of the cheaper Micron model.
Pliers for jewelry making and other similar work are made with nylon tips (tips).
It is a tool with non-slip grips and soft protection on the jaws that prevent fragile parts from scratching. They can also be used for domestic purposes.
Since this model is not designed to work with live electrical installations, its handles are not properly insulated from electric shock.
In addition, such tools are not reinforced and do not have a large margin of safety. They cannot be used for other purposes, since they will quickly become unusable from improper use.
- Wire stripper pliers BAHCO 2223 S-150 made of high quality alloy steel with plastic coated handles, oxidized and anti-corrosion treated; able to clean the wire up to 5 mm.
- Stripping pliers KRAFTOOL made of high quality carbon steel with plastic handles and anti-corrosion coating.
These products are of good quality at an average price, but can strip wires only up to 2.5 mm.
- Stripping pliers " ZUBR ELECTRIC», High-voltage high-quality tool steel, have a resistant chromium-nickel coating.
Wire stripping pliers are electrically insulated. They are suitable for electrical equipment with voltages up to 1000 V (AC) and 1500 V (DC).
With these tools, you can strip wires up to a maximum of 5 mm. Their mechanism allows you to remove the insulation without damaging the conductors.
Such products are safe and functional, but they cannot be used for other purposes.
- BAHCO 2713 A in vanadium steel, chrome-nickel coated and anti-corrosive.
- Adjustable pliers USAG (Italy) made of chrome vanadium special steel with 7 positions and enamel finish.
- ProsKit PN-P010N (254 mm) in S45C steel with insulated handles.
Adjustable pliers are a type of pliers that allows you to change the opening width of the jaws depending on the size of the object you want to grip.
Such models have latches for setting a certain opening width. They can grip both flat and round objects.
When squeezing the handles, the jaws of such a hand tool should converge tightly.
The regulation mechanism is performed with the hinge relocation:
- in the holes;
- in half holes;
- with fixing of the projections in the grooves.
The ability to change the position of the jaws is an undoubted advantage of this type, but the disadvantage is a certain bulkiness.
- Electrically insulated company models Knipex there are combined (ordinary and special power), as well as in the form of elongated pliers.
- All pliers Bahco are electrically insulated (side cutters, wire cutters, pliers, round-nose pliers, bolt cutters). The quality of these products is practically not inferior to Knipex, but the price is slightly lower.
- Electrically insulated combination models, platypus, wire strippers, side cutters and needle-nose pliers under the brand IRWIN (USA) are of high quality and safe.
This type allows you to service electrical installations with alternating voltage up to 1000 V or constant voltage up to 1500 V.
The dielectric pliers are equipped with well-insulated handles to ensure the craftsman is safe from electric shock. Good tools have multiple layers of insulation. They are easily recognizable by their thicker grips.
Different models of pliers can be dielectric. This increases their functionality and safety. However, some manufacturers' models do not have a limiter.

- Adjustable pliers Bahco with 11-12 positions, switching by 1 button.
- Adjustable pliers IRWINforged carbon steel with anti-pinch protection.
Sliding models allow you to grip rounded, hexagonal, square and flat objects as tightly as possible. The jaws of such a tool have a bend.
The dimensions of the sliding pliers are larger than those of simple types. The opening width of the jaws is adjustable in some cases by pressing a button and can be adjusted with one hand. The capture width is up to 45 and 65 mm.
- Side nippers KNIPEX Made from electric furnace vanadium steel, oil hardened, precision machined for long service life.
- Side cutters Bahco (high quality alloy steel with anti-corrosion treatment) with progressive cutting edge geometry.
- Diagonal cutters IRWINmade of chrome-nickel steel with hardened cutting edge.
The side pliers have a cutter on one side of the jaws. In fact, these are wire cutters designed for cutting (biting) objects made of various materials.
The side cutters can be used with wires of different stiffness, plastics, sheet metal, cardboard, etc.
When operating this model, it must be borne in mind that the variety intended for biting copper will not cope with elements made of harder materials (iron, steel). This will damage the cutters of the tool.
- Long nose pliers KNIPEX.
- Products with long lips Bahco.
- Long nose pliers IRWIN.
Long nose pliers are called long nose pliers, pliers, or needle nose pliers. They are designed to grip and manipulate objects (primarily wires) at a greater distance than conventional models.
These tools can be equipped with wire cutters.
Most often, this model is used to insert wiring into junction boxes, when laying wires, as well as when connecting electrical installations. They are also widely used by jewelers to fix stones in jewelry.
- Round nose pliers KNIPEX made of forged chrome vanadium steel, oil-hardened, withstand heavy loads.
- Model with round jaws Bahco made of high quality alloy steel with anti-corrosion treatment.
- Round nose pliers IRWINmade of chrome-nickel steel.

There is also a multi-functional (recycling) model. In addition, there is a folding model on the market that is equipped with a knife, an opener and a set of screwdrivers. This product is best suited as part of your camping equipment.
In this article, we will look at what types of pliers exist and what is important - how to choose the right one.
But judging by the number of questions, many people do not know the difference 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 driving nails with adjustable wrenches. But I believe that our audience is curious and skillful people. Therefore, let's figure it out.
These are pliers or pliers
Pliers and assembly pliers have two movable parts, fastened together by a hinge. Therefore, both tool classes are classified as pliers.
Scope of ShGI:
- assembly
- plumbing work
- electric installation work
With these tools, you can remove the nail from the plank, and tighten the nut, and replace the tap-box in the bathroom. But for working with electricity, only dielectric ShGIs are suitable, which withstand a certain voltage without risking the health of the worker.
Body materials
Pliers and pliers are made of tool steel grades CS45, CS55, chrome vanadium. The latter material is used less often and is more expensive, but the best in hardness and wear resistance. CS55 immediately follows chrome vanadium, while CS45 is used for budget hand tools.
An important parameter of the quality of a material is its hardness, measured on the Rockwell scale. It is designated by a number and a signature “HRC”.
Then the metal is processed by volumetric quenching and covered with a protective layer using:
- oxidation
- chroming
- phosphotizing
Both instrument classes have two types of handles:
- One-piece - all plastic or rubber coated. Suitable for aggressive environments. Plastic handles are attached with glue, in some cases the handles can turn or fly off - if poorly glued. Plastic is also not without drawbacks - it slips out of the palm when working with gloves. Rubberized handles hold tenaciously, feel good in the hand, but are easier to scratch and cut in the process.
- Two-piece handles - base made of regular or impact resistant plastic plus rubber cover. The plastic provides durability, even in case of falls from a height, and the rubber coating prevents the handles from sliding in the palm.
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. Needed for uniform gripping of workpieces.
The gripping surfaces of the pliers have only teeth and sometimes cutting edges, but no notches. Ideal for holding small parts, wires and fasteners.
You collect and repair electronics, mechanisms, up to wristwatches - you need pliers.
Another option in this group is bending wires and metal plates. Smooth surfaces without grooves allow you to grip the workpiece over the entire area without additional damage to materials.
Later we will take a closer look at the types of special pliers for precision work, but first we will deal with the pliers.
The combination pliers are multifunctional and have a clear focus on power work. The word itself is French, it can be translated as "rod clamp".
Assembly and jewelry work cannot be called the strengths of the 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 produced with a serrated notch, which increases the gripping force of the jaws. Therefore, you can grip parts with pliers, 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 the wire and fasteners. Also, in the area of \u200b\u200bthe hinge, there can be an additional recess for cutting the same wire.
A number of models of pliers are produced with a sliding hinge - in order to widen the jaws and grip workpieces with a larger diameter.
Since the pliers are more powerful than pliers for their purpose, they use a material of greater strength and hardening. If the standard of hardness 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 the pliers:
- The pliers must be lubricated, otherwise they will not move, or the sponges will come together sharply, with a jerk - so you can injure your hand.
- Choose your pliers so that they don't pinch your fingers when closing.
- 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 these products are simply convenient to use in small niches in walls, when working with recesses and holes in the ceiling and floor.
We openly indicate the parameters of our tools on the site, and what materials we use for them.
Long nose pliers. They perform functions similar 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. Cutting edges are designed to handle wires and wires. Steel material CS55.
A variant of the modified tool with curved jaws is the pliers of platypuses. The tool is great because it allows you to access wires and fasteners in curved or angled spaces. It contains both serrated clamping surfaces and cutting edges. Again, they are more suitable for wire and wires than nails. Steel material CS55.
What are the round nose pliers for: For curly bending of the wire. Tapered jaws allow you to bend workpieces with a radius of up to 0.6 mm. Used primarily by jewelry manufacturers. The working part is made of high carbon steel CS55.
All precision pliers are manufactured with two-piece handles. We use impact-resistant ABS plastic as a base for them, and additional comfort is achieved due to TPR rubber inserts.
It is a rough and resilient 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 wire cutting as it has only a cutting edge, no clamping surfaces. The key property of the tool is its cutting properties. An excellent option for an electrician, installer and repairman.
Many people are interested in the difference between nippers and side cutters. A separate note could be written about this, but in short, side cutters are a kind of ticks.
Metal processing
We use metal oxidation or bluing to protect the VIRA pliers. This helps protect the tool from moisture and rust. With this treatment, the pliers can last 5 years longer.
Quality standard
All VIRA GIs meet the requirements of the German Geprüfte Sicherheit (GS) standard. This sign denotes products that meet safety and production quality.
How to use pliers:
- Check tool lubrication. He gets to the store already well oiled, but it's better to make sure of this. Without lubrication, the clamping surfaces will not move, the pliers will rust.
- Pliers are still not designed for gripping large parts. Use the tool for medium to small workpieces.
- The tools are not intended to be aggressive. Excessive pressure on the handles over time spoils the condition of the cutting edges, teeth of the clamping surfaces. In addition, the appearance of the processed parts suffers.
- Use pliers to grip the flat parts of the workpieces.
- 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 the hinge.
The pliers should not "walk" too much in the place where the moving parts are fastened. Take the tool in your hands horizontally, with the jaws away from you and try to wiggle the pliers by the handles up and down. The joint in the hinge without large backlash indicates the quality of the tool assembly. Strong backlash - moving parts are poorly fitted.
- Check the flattening of the lips
The clamping surfaces of the instrument must be sufficiently firmly pressed against each other during mixing. This is important for tools used in precision work, because if the sponges do not come together well, small parts and fasteners will fall out and not be held.
- Convenience of handles
Make sure that they are firmly in place and do not fly off, pleasant to your hand, do not slip in your palm. If the handles scratch your fingers and hand at least a little, then with constant work you will find calluses and scratches.
I hope you now know the difference between pliers and pliers and can make your own 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.
Repair work requires the use of a wide variety of tools. The most popular are pliers and pliers. Many people assume that these are names for one fixture. This fundamentally erroneous opinion is widespread enough, but has no substantive justification. Professionals, of course, know how they differ from each other, but not home craftsmen who take out a toolbox only when absolutely necessary.
Pliers and pliers are both practical and versatile. They, unlike many other tools, cannot be replaced with other devices. The confusion between these devices arises from external similarities, but there is a difference between them. It's pretty weighty. Both tools are involved in electrical and repair work, but serve different purposes. The similarity lies only in the fact that both devices are hinged-pliers.
What are pliers and the scope of this tool?
The device consists of metal lips with notches, united by a hinge 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 the hand.
The pliers are flat. Due to its design features, using this tool, you can easily hold hardware and parts of various sizes. Pliers are used to deform cables, wiring and products made of sheet material.
The sizes of fasteners and parts have their own limitations. The tool can hold hardware and products with dimensions not exceeding 19.5 cm. This is quite enough for a wide range of work without any problems. In addition, pliers are often used like a wrench to loosen nuts.
Tool varieties
The difference between pliers and pliers lies not only in their design and purpose, but also in the fact that the latter are available with different shapes of working surfaces:
- Long and narrow lips... This type of plier is used where a regular-sized tool simply cannot fit.
- 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 intended for manipulating parts made of fragile materials.
Tweezers-like pliers 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 isolated, 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, you cannot use pliers. Otherwise, there is a possibility that the insulation simply cannot withstand the applied voltage, and this poses a threat to life.
Selection features
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, curved nose pliers 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 when delicate work is required. Similarly, pliers and silicone tips are used, which are worn over regular sponges.
Pliers: description and purpose
The multifunctional tool is a relative of the pliers. Both devices have a similar appearance and purpose. This is what misleads many home craftsmen that pliers and pliers are one and the same tool. This myth can be dispelled by a closer acquaintance with this device.
On each side of the working surface of the pliers there is a notch on which there are notches. The latter allow you to grip and hold surfaces of a wide variety of materials. Pliers are widely used in plumbing and when performing electrical work.
The combined surface of the tool makes the pliers one of the most sought after tools. Along with the notch, the work area also has a flat area. In addition, many types of pliers have two shallow, small indentations. They allow you to work with parts of various sizes.
Features and varieties of the instrument
The pliers hinges are located in special grooves. This allows you to regulate 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 "adjustment". To rearrange the diameter, you need to spread the handles and reinstall the hinges into the groove.
Most types of pliers are designed with side cutters. This accessory further enhances the use of the tool. Side cutters can cut cables and wires, and quickly get rid of insulating cores. One of the working sides of the pliers has edges. They allow you to cut even hard metal wires.
Pliers are of two types - locksmith and for use in the electrical field. The latter must necessarily have a marking in which the voltage for which they are designed is indicated.
The difference between pliers and pliers
To find out exactly the difference, you need to collect all the differences between pliers and pliers. They boil down to the following points:
- The 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 fixtures on sale, but they are extremely rare and used, since one work area is usually only additional, and not fully functional.
- Material. Pliers, unlike pliers, allow you to perform compression with much greater force. To ensure a long service life of the tool, only high-strength steel is used for its manufacture. Pliers can be made of less durable metal without sacrificing functionality.
- Additional features. Pliers never come with side cutters. Pliers are usually produced with this cutting attachment in their design.
Another feature that distinguishes pliers from pliers is that the former allow you to change the clearance of the working area, that is, to adjust the compression ratio of the part being manipulated.
How to choose a quality tool?
Pliers and pliers are two completely different tools, but the recommendations for a good buy for them are absolutely identical:
- The hinge-type connection should be free of play, and the stroke should be smooth and soft. If you cannot close and open the handles without excessive effort, or, on the contrary, the jaws move completely freely, it is better to refuse to buy a tool.
- The handles deserve special attention too. They should be made not only of a comfortable shape, but also of a material that does not slip. If the tool is planned to be used to perform electrical work, this part of the device necessarily assumes 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 nearly impossible to work with such pliers or pliers.
The manufacturer and cost play an important role. If you plan to use the tool part and to perform critical work, it is immediately recommended to purchase a professional model.
Multifunctional tools are found in any home. Pliers and pliers are indispensable in plumbing, when repairing triplets and mechanisms, during electrical work. Some people mistakenly believe that these tools are not different from each other. In fact, they belong to the same group, but they differ in purpose and cannot be interchangeable.
Features of pliers
If you need to fix an item with metal parts or carry out construction work, then use pliers. The working part resembles a pyramid in shape, the sponges are flat, hence the name. There are special notches on the inside. Two metal parts of the pliers are connected crosswise. Under the working part there are handles that move thanks to the hinge. The smooth surface allows you to bend, clamp and fix soft metal alloy products, wires, metal sheets. Pliers are sometimes used to loosen nuts, but this is not a basic function.
The tool can have a different appearance. Pliers are divided into 6 types, each of which is designed for specific manipulations.
- With an elongated and narrow work surface.The tool has a low compression force. Used for small soft metal alloy parts.
- Curved ends.Helps to work with hard-to-reach parts. Excellent pliers for electronics, allow you to get to the elements under the boards.
- With thin and elongated ends.Most often used for fixing small nails. The handles help to increase the grip force as needed.
- For working with delicate materials. The working part is characterized by a softened or smooth coating. May have silicone pads. They are used when working with materials that can break or scratch when inaccurate.
- Combined can be made in two versions.The first subspecies is distinguished by the presence of a recess on the working surface. The second subspecies has a sharp edge. Combination pliers are helpful when you need to grip a rounded tube or bite off a piece of fine wire.
- Dielectric pliers.They differ in the presence of insulation on the handles. Used when working with electricity. Please note that the handles indicate at what maximum voltage can be applied.
Remember that pliers are used to grip medium and small parts, large ones cannot be used. Remember to periodically lubricate moving parts. Certain rules of work will help to increase the service life of the tool.
- The gripper helps to hold the part in position so that it does not slip. You can guide the product with pliers. The function is in demand in cases when the hands cannot physically complete the task, or the strength of the fingers is simply not enough.
- You should not make violent actions while seizing an object. Rough handling can damage the tool itself or damage the surface of the part.
- Classic pliers only grip flat parts. For rounded ones, use a combined look.
- When working with electricity, only hold the tool by the handles. If possible, turn off the voltage before starting manipulations.
- Only soft metals can be nibbled with pliers. Do not use for cutting off parts of steel parts: this will damage the tool.
- The functionality of pliers is most in demand in radio installation work.
What are pliers?
Prevent corrosion on the metal, always lubricate the work surface. This will help extend the life of the pliers. In addition, there are some rules of use.
- Pay attention to the distance between the handles to avoid pinching your fingers.
- Pliers make it possible to grip flat and cylindrical parts.
- Can be used to hold nuts. It is better not to loosen tightened nuts with pliers.
- It is important not to push, but to pull the tool while working.
- If you need to cut the wire, set it perpendicular to the cutting end.
- When working with electricity, hold the tool by the insulating handles.
What's the difference?
According to GOST, pliers and pliers belong to hand-held fitter's tools. It is quite easy to visually distinguish them by their essential features.
- The size. The pliers have short and massive jaws, large handles. The tool is smaller.
- The difference in the shape of the working area. The pliers are distinguished by oval notches, while the pliers have smooth lips.
- Only the pliers are equipped with a swivel joint.
- The pliers are more versatile and the pliers are narrower.
- Pliers work with flat parts. If you need to grab a round or cylindrical - with pliers.
- The pliers have a more contoured surface, so the grip will be more secure.
