In this case, the hardness of the hinge cutting elements, the edges of the jaws and the clamping surfaces should not be lower than the recommended HRC values according to the Rockwell scale. Before the choice begins, it is not unreasonable to know the difference between pliers and pliers.
How to distinguish pliers from pliers
Pliers and pliers are considered to be an articulated-sponge tool intended for carpentry, carpentry and electrical installation work on the wiring of low-current electric networks. In the arsenal of a home master, the availability of these tools is mandatory. With the use of pliers, it is possible to clamp or grip not only parts of different configurations, but also pipes of small diameter.
What is the difference between pliers and pliers? The difference from pliers, obviously, because the pliers have one, rarely two pairs of denticulate notches. Toothed notches are designed for grasping and turning parts of a classical cylindrical shape. In addition, the pliers are decorated with a notch that is located on the notches and the flat part of the jaws.
The design of pliers
According to the type of work performed, the design of pliers can be different. Pliers made in the following versions:
• with an elongated shape of the sponges
• with short sponges.
Combination pliers with elongated jaws up to 200 mm are a bench tool designed to manipulate, hold, twist and pull elements and parts.

Types of pliers
There are the following types of pliers:
• pliers dielectric
• Combination pliers for eyelets
• combined pliers.
To find out what kind of pliers are, just look at their photos.
pliers dielectric
Dielectric pliers distinguish handles with electrical insulation according to IEC (IEC) 60900, which allows working with tools and equipment with an operating voltage of up to 1000 V AC, and up to 1500 V DC.
Soft cast handles of pliers, streamlined form with insulation allow comfortable and safe electrical work.
So, for example, plastic knipex pliers are successfully used when installing electricity meters in an apartment. Safety of work is provided by the body of handles made of plastic reinforced with fiberglass. Reliable electrical insulation completely eliminates the possibility of electric shock. Handles pliers have a ribbed surface, eliminating any slip during installation. The flat sponges of the tool are equipped with teeth that provide good grip. With a slight weight of pliers about 130 grams and a length of handles of 180 mm, pliers work for a long time is not burdensome.
pliers for eyelets
The most popular tool for the home master can be confidently called pliers for eyelets. Moreover, a metal or plastic ring - eyelet with a diameter of up to 7 mm is often used for the arrangement of curtains and curtains for the windows of the apartment.

With the help of pliers, the installation of the eyelet is simplified to a minimum: several vigorous grips with handles and metal rings are completely fixed along the edge of the material.
combined pliers
Models of combined pliers combine several functions of a metalwork tool: pliers, thin wire cutters and side cutters. Models of combined pliers are made of carbon steel, and the cutting edges of the jaws are hardened to increase the service life.
The metal parts of the pliers are treated and polished, and also coated with anti-corrosion lacquer. Handles of combined pliers are made of two of the same materials, handles are comfortable in the hand due to ergonomic design.
How to choose pliers
If the home master does not intend to produce complicated wiring or locksmithing work, and the work carried out will be of an episodic nature, then it is not necessary to purchase an expensive professional tool. It will be enough to buy household pliers. What qualitative parameters should I pay attention to when choosing?
Of course, this is a quality material for making tools. The best pliers are made of quality steel. That it is really steel and brand of the brand can be seen firsthand on the case of pliers in the form of engraving. It is also necessary to pay attention to the anti-corrosion coating of the tool. The best are coatings made of chromium and vanadium. By the way, the brilliant pliers of pliers are not an indicator of excellent quality. Get in direct contact with the pliers. If your palm feels confident protection against slipping, and there is no external strengthening of the handles with pins, the handshake can be considered friendly.
Such a "friendly interface" will serve a good home-master. And, of course, test drive the pliers. Well, here without a "divorce" simply can not do. Dismantle the handles of the tool and follow the smoothness of the stroke. Repeat the procedure several times. If eight times the "divorce" of pliers on the face of the saleswoman of the building supermarket watching your manipulations, not a single muscle flinched, it means that it's time to pay for a new handy tool.
