Pliers and pliers - the difference exists! It is with these words that I would like to begin a review of two unremarkable things, which each owner has. Among the variety of tools needed by each master, it is they, pliers and pliers that take pride of place. They are so simple and multifunctional that neither a mechanic, a mechanic, nor an electrician can do without them. Everyone knows what these similar at first glance objects look like.
The difference between pliers and pliers is the shape of their working surface.
Why at first glance? After all, when we say “pliers”, we present a tool with two handles, and with the word “pliers” we represent the same tool. It's all about the external similarity. But there is a difference, and the difference is significant. Firstly, the difference in the manufacturing technique, secondly, in the GOSTs, and thirdly, in the functional purpose. These differences need to be considered not only by the manufacturer, but also by the end user.
Types of hinged pliers tool
Hinged-tongue tools consist of 3 parts: heads (sponges or cutters), handles and axial movable hinge. Such tools are among the oldest in history. Blacksmithing has been known since ancient times.
Pliers: 1 - sponge with adjustable hinge, 2 - hinge, 3 - hole for the hinge in the movable sponge, 4 - handle.
The ancient Greek god of fire and patron of the blacksmith's craft, Hephaestus, is depicted with a hammer and tongs. Over time, society changed, craft changed with society, and tool with craft. At what period of time pliers appeared, it's hard to say. But we can conclude with confidence that a very useful and extremely necessary tool has come out.
Hinged-tongue tool has many types. In general, the so-called pliers, nippers, round pliers, pliers and pliers. Each of the tools has its own dimensions, shape of the working surface (sponges) and purpose.Back to table of contents
Pliers, nippers and round nose pliers: tool characteristics
The working surface of the pliers is similar to tweezers, but it also has the possibility of greater compression.
Ticks are lever tongs with elongated handles connected on a hinge. Basically have a short pointed or flat sponge. The main task of ticks is to capture parts. For example, carved ticks pull out hammered nails, and blacksmith ticks allow you to hold red-hot metal. Also, ticks are called some electrical tools (strippers, "swage").
Nippers are called mites, in which the sponge is made in the form of cutting edges. Used for cutting wires, wire, individual wires. Nippers are side (side cutters), end, end and bolt cutters (for cutting thick metal rods).
Round pliers have a working surface (sponge) of conical or cylindrical shape. Used for uniform and shaped bending of wire or narrow thin plates.Back to table of contents
Pliers: types, properties, application
Pliers is a hand tool designed to work with metal products and electrical work. The working surface of its pyramidal shape, sponges are flat (hence the name), notches are applied on their inner side.
Like pincers, they consist of two parts connected in the form of an X. The working part goes into the handles and moves by means of a hinge. Flat jaws allow you to grip, bend, firmly hold, twist the wiring, parts made of wire and soft metal. Here it is necessary to emphasize the advantage of pliers - their versatility, because, besides the main purpose, this tool is suitable for use as a wrench of the required size, although this type of work is not entirely peculiar to it.
There are pliers of several types, each of which is designed to perform a certain kind of work:
Joiner's and carpentry tools: a, b - nippers, in - pincers, g, e - pliers.
- Pliers with elongated narrow jaws. This type of tool has a lower compressive force and is designed to work with small parts.
- Pliers with angled curved jaws. They work with parts, access to which is limited. For example, in the repair of electronics it is often necessary to get close to the part that is hidden under the board.
- Pliers with extended long sponges - "duckbill". Such a tool in functionality is more similar to tweezers, but, thanks to the handles, it has a greater compression force.
- Special pliers for delicate work. The working surface of such a tool is a smooth or soft coating that does not damage the parts. For the above types of pliers, silicone nozzles can be manufactured that perform a protective function.
- Combination pliers - on the working surface near the flat jaws made either a notch with notches to hold the rounded parts, or a cutting edge, like a nippers.
- Dielectric pliers for working with electricity are equipped with insulating handles that allows you to work with such a tool under voltage. The handle of such pliers indicates the maximum voltage at which work is allowed (usually 1000 V).
Passatizhi: multifunctional brother or an independent relative?
The word “pliers” came to us from French: Pince-à-tige = pince (clamp) + tige (stem). According to GOST, pliers are a tool designed to grip and clamp pipes and parts of different shapes.
Externally, the pliers and pliers are very similar, with one difference in the fact that there is a notch with a notch on the working surface of the pliers, which helps to keep smooth and rounded surfaces: rods, pipes with a small diameter.
Pliers are different from pliers in that they have cutouts for holding objects and built-in cutting edges for cutting the wire.
Usually, in the case of pliers, in addition to the cutout for pipes, the working area also has flat sponges, side cutters for stripping and cutting soft wire, and edges for cutting hard wire.
In some types of pliers, you can adjust the compression force of the sponges. To do this, rearrange the hinge in the desired groove. This feature also allows you to increase the width of the sponge opening, which is necessary to capture larger parts.
For work in electrical installations, dielectric pliers are manufactured, with identical marking of maximum voltage (1000 V).Back to table of contents
The main differences between pliers and pliers
Considering the seemingly identical, but functionally different tools, you can summarize their differences and features:
- The working surface of the pliers is flat, and the pliers have a special notch.
- The opening width of the jaws and the clamping force of the pliers are fixed, while for the pliers they are adjusted by moving the hinge.
- Pliers have a narrow functionality, which is to hold the parts (clamp), whereas the pliers are multifunctional and include side cutters, biting the edge, may have an additional notch on the working surface.
- Pliers are made of steel of greater strength than pliers. This is due to the fact that the pliers are designed for greater compression force of the working surface.
We hope that this review will allow you in the future not only to correctly use the name of the necessary tool, but also to use this tool for its intended purpose.
