There is no such type of plumbing work that can be done without the use of pliers. In amateur slang, this tool is also called pliers. Briefly describe the tool - it consists of two "X" figuratively connected metal elongated parts.
Moreover, the swivel is not in the middle, but is shifted towards the working area in the ratio of 1/3 or 1/4. The long part is designed in the form of handles, and the short part is adapted for grabbing and squeezing objects.
And yet, a similar name is pliers and pliers - what's the difference?
These products have common roots. Both devices belong to the category of pliers. They are designed to capture, hold and squeeze a variety of objects.
Let's define each of them:
pliers
Manual multifunctional locksmith and electrical tool. Designed for gripping, crimping, holding parts and blanks of round and other shapes with the help of hands.
In the presence of a dielectric coating on the handles, it allows you to perform electrical work without turning off the voltage in electrical installations up to 1000 volts.
The shape and dimensions of the device are determined by the GOST 17438-72 “Pliers. Specifications".
Pliers device
On the inner surface of the jaws there are one or two recesses of different sizes to capture round objects. Notches must be formed on the grooves to prevent slippage. The angle and depth of the teeth allows you to unscrew loose nuts.
IMPORTANT! When using pliers as a wrench, the edges are damaged. Therefore, this application is the exception rather than the rule.
On the jaws, on the inside in the hinge area, a wire cutter can be molded in the form of wire cutters. The hinge mechanism often has a slot for cutting the wire using the offset method.
With the cups open, the slots are combined into one, the workpiece is laid, and the handles are closed. At the same time, even steel wire is easily bitten.
The outer shape of the sponges has a different design. Rectangular, with sharpened edges or semicircular. This is done for ease of penetration into cavities with limited access. For special work, the product can be given a special shape, which in no way limits its capabilities.
In order to increase functionality, the tool is completed with a screwdriver and an awl (hole punch). However, for the average user, the classic performance is more familiar.
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.
Multifunctional tools can be found in any home. Pliers and pliers are indispensable in plumbing, when repairing triples and mechanisms, during electrical work. Some mistakenly believe that these tools are no different from each other. In fact, they belong to the same group, but differ in purpose and cannot be interchanged.
Plier features
If you need to repair an object 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. On the inside there are special notches. Two metal parts of the pliers are connected crosswise. Under the working part there are handles that are set in motion thanks to the hinge. The smooth surface allows bending, clamping and fixing products made of soft metal alloy, wires, metal sheets. Sometimes pliers are used to loosen nuts, but this does not apply to the main functions.
The tool may have a different appearance. Pliers are divided into 6 types, each of which is designed for specific manipulations.
- With an elongated and narrow working surface. The tool has a low compression force. Used for small parts made of soft metal alloy.
- With curved ends. Helps to work with hard-to-reach parts. Excellent electronics pliers, 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 increase grip strength when needed.
- For work with details from delicate materials. The working part is distinguished by a softened or smooth coating. May have silicone overlays. They are used when working with materials that can break or scratch with inaccurate exposure.
- Combined can be made in two versions. The first subspecies is distinguished by the presence of a notch on the working surface. The second subspecies has a sharp edge. Combination pliers will help when you need to grab a rounded tube or bite off a piece of thin 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 it can be used.
Remember that pliers are used to capture medium and small parts, large ones will not work. Remember to periodically lubricate moving parts. Certain rules of work will help to increase the life of the tool.
- The grip helps hold the part in position so it doesn't slip. You can guide the product with pliers. The function is in demand in cases where it is not physically possible to perform the task with the hands, or the strength of the fingers is simply not enough.
- It is not necessary to perform violent actions while capturing an object. Rough handling can damage the tool itself or damage the surface of the part.
- Classic pliers allow you to grip only flat parts. For rounded ones, use a combined look.
- When working with electricity, hold the tool by the handles only. If possible, turn off the voltage before starting manipulations.
- Pliers can only cut through soft metals. Do not use for biting 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 increase the life of the pliers. In addition, there are some rules of use.
- Pay attention to the distance between the handles so as not to pinch your fingers.
- Pliers make it possible to capture flat and cylindrical parts.
- Can be used to hold nuts. It is better not to unscrew the tightened nuts with the help of pliers.
- It is important not to push, but to pull the tool when working.
- If you need to bite the wire, then install it perpendicular to the cutting part.
- When working with electricity, hold the tool by the handles made of insulating material.
What is the difference?
According to GOST, pliers and pliers are hand-held bench and assembly tools. Visually, they are quite easy to distinguish by essential features.
- Size. Pliers have short and massive sponges, large handles. The instrument is smaller.
- The difference in the shape of the working area. Pliers are distinguished by oval notches, while pliers have smooth jaws.
- Only pliers are equipped with a swivel joint.
- Pliers are more versatile, and pliers are narrow-profile.
- Work with flat parts with pliers. If you need to grab a round or cylindrical one - with pliers.
- Pliers have a more curly surface, so the grip will be more reliable.
Pliers and pliers belong to pliers, another name for which is pincers. All of them are designed to manipulate objects, as well as to perform various operations, up to the extraction of teeth. Moreover, even dental pliers are diverse. The situation is similar with such household tools as pliers and pliers, the difference between which exists, although not obvious to everyone. About what these items are, for what purposes they are used - will be discussed in this article.
Pliers
This instrument comes from our childhood. A large encyclopedic dictionary of technical terms defines pliers as a hand-held metalwork and assembly tool equipped with rectangular-section pyramidal sponges used to grip and bend small metal parts. From the definition it can be seen that with pliers you can:
- hold an object (metal strip, washer, nail, electric wire);
- bend a metal strip, wire.
That is, their main purpose is capture and manipulation. The tool can only hold and bend. It is not for nothing that among its many relatives - pliers - it is now extremely rare in the windows of tool stores. Domestic pliers must comply with GOST 7336-93, according to which they are:
- With short (25–55 mm) or long (50–63 mm) jaws. By the way, the criterion for belonging to a particular type is not the length of the jaws, but the ratio of their linear dimensions to the dimensions of the clamping handles.
- With plain or insulating handles. The latter are manufactured in accordance with GOST 11563-94, which regulates the requirements for hand tools for performing work under high voltage.
Available instrument sizes: 125–220 mm (total length).
Domestic tools are made from U7A carbon tool steel with volumetric hardening up to 45 HRC units. A decorative coating for corrosion protection is applied in one of 3 ways:
- chemical oxidation. Color of a covering - dark gray with black outflow.
- chemical phosphating. The surface of the instrument is matte gray, of various tones (from light to dark gray).
- Chrome plating. This coating is the most durable and corrosion resistant.
Pliers. Everything is captured
If you put pliers and pliers next to each other, the difference will become noticeable. Next to their modest relative, pliers look more solid, and they are capable of more in work. If the pliers can only lightly grab the object being held, then the pliers will clamp it much more securely. This is especially good when gripping cylindrical parts (bars, studs, bolts), thanks to the jaws, which are equipped with special notches with a large notch. Some models have two pairs of grooved grooves of different depths, and sometimes they make an additional semicircular groove located on the side of the handles (it can perform the crimping function). At the end, the sponges are made flat, equipped with the same notches as those of the pliers. Sometimes pliers are supplied with additional corrugated elements made on the inside of the handles, next to the hinge, a lever of the second kind is obtained.
As standard, all pliers have cutting blades (side cutters) located next to the hinge, which can be used to cut thin metal strips, electrical wires. Wire and thin nails can be cut with two cutouts on one side of the tool, which work on the principle of a guillotine. At the same time, the cutting force pinches the part in the grooves, so that you can squeeze the handles with both hands. The force increases even more due to the increased ratio of the lever arms - the cutting grooves are located close to the axis of rotation. Due to the additional working functions, pliers are often called combination pliers. Usually they have one (fixed) axis of rotation of the handles. There are designs with an adjustable joint - two- or multi-position, which expands the clamping range of the tool.
Pliers are made of stronger steel than pliers. Usually chrome molybdenum or chrome vanadium steel is used. The gripping jaws are hardened up to 53 HRC, and the edges of the side cutters are hardened up to 60 HRC. A little about handles. The amount of force applied depends on their shape and material. For this purpose, ergonomic pads are used to increase the comfort of the grip. The material is rubber or a two-component coating (eg thermoplastic rubber with santoprene linings). Dielectric handles (made of plastic) must have a confirmation inscription: work under voltage up to 1000 V.
Find 6 differences
So, pliers and pliers. The difference between them is in purpose and functionality. Consider the main distinguishing features of the two tools. The presence of at least one sign means belonging to a particular class.
- Pliers - highly specialized, pliers - a multifunctional bench tool;
- The jaws of the pliers are flat, with a fine notch along the entire length;
- For pliers, the flat part of the jaws is shorter, and to capture cylindrical parts, they are equipped with figured (radius or triangular) notches with a large notch;
- Pliers have cutting edges (nippers or side cutters), as well as transverse cutters for cutting wire or nails;
- Can be equipped with a reversible swivel joint;
- Pliers are made of stronger and highly hardened steel.
Summing up, we can say that pliers are a single tool, and pliers are multifunctional, replacing a small hand vise, side cutter and end cutters. Buying pliers today is more appropriate. And pliers, most likely, will be found in everyone in their father's or grandfather's tool.
Content:
There are many varieties of pliers. These include the familiar wire cutters, pliers, round nose pliers, as well as pliers and pliers. Each listed tool is designed for specific purposes, has its own size and shape of the working surface. The design includes three main parts: a head in the form of sponges or incisors, an axial movable hinge and handles. However, they all differ in their own individual qualities. In the article, we will look at the difference between pliers and pliers.
Pliers: purpose and design features
Pliers belong to the category of hand tools used in electrical work and operations with metal products. The working surface has a pyramidal shape, notches are applied on the inside of the flat sponges.
The design consists of two parts that are connected by the letter X and are fixed on a hinge that ensures their mobility. Each detail consists of a working part, passing into the handle and making up a single whole with it. Thanks to the flat surface of the jaws, it becomes possible to securely grip, bend, confidently hold and twist wiring, as well as various parts made of wire and soft metals. In addition to their main purpose, pliers can be used as a wrench, the dimensions of which are limited by retractable jaws.
Types of pliers:
- A tool whose narrow jaws are elongated has less compressive force and is used in working with small parts.
- In other designs of pliers, the jaws are bent at a certain angle. This makes it possible to work with details when access to them is significantly limited. This type of pliers is especially relevant for electronic devices, where parts are hidden under the boards.
- To work with live parts, there are special dielectric pliers. The isolated handles allow to work freely in the presence of electric current. Their handles are marked with an indication of the permissible maximum voltage at which you can work.
Pliers - a universal tool
The basis of pliers are pliers, which appeared much earlier and were intended to perform the simplest functions. As a result of upgrades, pliers have turned into pliers and have become a sought-after multifunctional tool. Pliers are equipped with small side cutters, two small cutters located on the sides. In the middle there is a round corrugated hole through which small bolts and nuts can be screwed.
Assembly and locksmith work is not complete without pliers. They perform the functions of pliers and can perform many additional operations. Thanks to numerous devices, pliers successfully work with various parts, regardless of their configuration. Thus, pliers acquired the universal qualities of many tools at once. They became simultaneously pliers, side cutters and cutters capable of cutting the wire of the widest range of sizes and diameters. For some samples, the ends of the insulated handles with an awl and a screwdriver.
For installation and plumbing work, mainly dielectric and combined pliers are used. The first option refers to, the handles of which are insulated with a special dielectric plastic. The second design is considered more versatile, combining various tools. This allows you to perform a lot of plumbing work of the widest range and focus.
What is the difference between pliers and pliers
Based on the previous description of each tool, we can conclude that the main difference between pliers and pliers is their versatility. This is due to the fact that pliers have only one function - gripping, and only some models can cut metal wire.
Initially, only pliers were used for all work, to which there was no alternative. Gradually, they were modernized and improved to the technological level of pliers, which stood out as a separate tool. Pliers can bite through almost any wire, while pliers have a significantly limited ability to do so. Pliers reliably capture any part, thanks to the recesses, and this cannot be done with pliers. Before choosing one or another tool, it is necessary to determine in advance the list of those works that will have to be performed.
Which tool to choose
The quality of the work performed with its participation depends on how correctly the tool is chosen. Therefore, despite the fact that pliers have significant differences from pliers, the choice of each of them must be approached responsibly.
Pliers require more attention when choosing due to the large number of different functions. Currently, a large range of these products is offered, so the probability of error becomes quite high. It is advisable to collect all the necessary information about the desired tool in advance and only after that go shopping.
First of all, you need to pay attention to the material from which the pliers or pliers are made. It is best to purchase a product from reputable manufacturers, rather than cheap Chinese products. The surface of the material must be uniform in all places, and all parts must be equally strong. Pliers are usually covered with anti-corrosion materials. It is recommended to hold them in your hand in advance, trying on how comfortable they will be when doing work.
