How to choose a screwdriver set: tips for choosing dielectric tools. rating of the best models of 2019 (105 photos)

Purpose and characteristics

The dielectric screwdriver is used mainly when working with electrical networks, electrical power equipment or any other electrical appliances that are directly under high voltage. Moreover, it is worth noting that dielectric screwdrivers are used when working with electric current, the voltage of which should not exceed 1000 volts. When working with voltages above this, it is strongly recommended to use specialized protective measures.

A dielectric screwdriver handle covered with a special non-conductive material will help to achieve the level of protection against electric shock. This function of the screwdriver makes it possible to work with products intended for fasteners.

Another characteristic feature of such screwdrivers is their special coating over the entire area, right down to the tip, which undoubtedly brings the degree of protection against electric shock to the maximum value, since the master, when working with a screwdriver, can accidentally touch its bare part.

What are the types of screwdrivers

Dielectric screwdrivers designed for the behavior of work with voltages up to 1 kV are made of the following elements:

The metal base and the tip of the screwdriver are made of steel products marked with U7 or 8HF signs. In other words, such materials are also referred to as instrumental with a high degree of strength.

The handle is made from materials such as polyethylene or polycarbonate and is covered with an additional protective layer of polyformaldehyde.

In order to be sure of the level of protection of the screwdriver, you should make sure that the handle of the tool is an excellent dielectric, that is, it does not conduct current. However, handles can be made from other different materials, but it is always necessary to check the level of protection of the tool used when working with high voltage or ask the seller to review the dielectric screwdrivers.

This type of tool is rarely performed in the form of other forms - hexagonal or torx, which means that when choosing a product in a store, it is worth giving great importance to this. What else you must know when buying this tool is described in more detail below.

Subtleties of choice

When choosing a set of dielectric tools for yourself, first of all, pay attention to the composition of the tools - sets from different manufacturers often vary in configuration. And also do not forget about the price / quantity / quality ratio

The table shows the characteristics of some sets of dielectric tools from different manufacturers.

And also manufacturers often bring to your attention such sets of tools, where one handle-holder with a hexagon socket and many different slotted inserts - both straight and curly. The convenience of such sets in the reduced weight of the set, a variety of tips. The tips and the internal hex groove of the handle for their insertion are magnetized for a secure fit.

By the way, all manufacturers reserve the right to change the nomenclature, technical characteristics, composition and appearance of tools without prior agreement with distributors (dealers) of their goods, therefore the data given in the table can be considered only for informational purposes.

The following video will help you choose the right dielectric screwdriver for you.

When choosing a professional dielectric tool kit, pay attention to the handle material. Currently, most manufacturers make them two-component - when the top layer of insulating material is abraded or chipped off and a bright inner material is visible, this is a signal to the user that the tool needs to be changed, because it is already unsafe to work for them.

Features of SHTOK products

Dielectric SHTOK tools, both in single and in-set versions, have a number of characteristics that distinguish them favorably from similar ones:

• two-component version of the handle insulation;
• the ability to work with screws recessed in deep and narrow slots;
• increased tool life due to phosphating of the working rod - this method increases the strength of the material to abrasion, cracks and improves protection against metal oxidation;
• tool tips are magnetized, which increases the convenience of their use and allows you not to lose even small end screws unscrewed from vertically installed electrical devices;
• comfortable handle with anti-slip coating.

But it should also be noted that the range of SHTOK tool kits includes a torque handle with interchangeable slotted working attachments. This type of screwdriver is necessary for carrying out electrical work on equipment, the screws of which must be tightened with the tightening torque specified in the technical documentation - that is, when tightening the screws, you need to strictly regulate the force with which you tighten them.

Of course, it's up to you to choose the tools, but heed the advice of a professional - it's better to buy a really high-quality set that will last a long time and ensure your safety.

How to choose dielectric screwdrivers

When choosing a dielectric screwdriver, it is imperative to remember that it is required when working with high voltage current, therefore, it is imperative to note several factors for yourself

First, you need to pay attention to the size of the purchased product.

Dielectric screwdrivers, like conventional ones, are available in various shapes and sizes, also designed for different types and sizes of fasteners for electrical networks or electrical equipment

It is important to select the tip of the screwdriver strictly according to the size of the fastening element - this will not bring any complications during the work .. You should familiarize yourself with the size of the purchased tools, namely:

You should familiarize yourself with the size of the purchased tools, namely:

• Width and thickness of the screwdriver base
• Width and length of the handle
• Base length

If you have complete information about the required screwdriver, you can purchase only one you need, otherwise it is recommended to pay attention to special sets of dielectric screwdrivers, which already consist of numerous types of dielectric screwdrivers.

One of the most budget-friendly kits usually consists of 3-4 instruments, while more professional kits consist of 8-10 pieces, and also include a magnet and even a few probes.

When purchasing this equipment, be sure to check the quality of the manufactured tools. Never buy these products if they show even microscopic chips, cracks or scratches - this could lead to a fatal accident.

A dielectric screwdriver must be covered with a special layer of rubber and have clear boundaries of the tip for work, which, by the way, is magnetized for some manufacturers, which allows you to easily get fasteners from hard-to-reach places.

This is usually indicated in the description of the instrument on the label or verified in practice.

When buying, you should also pay special attention to the production of products in accordance with GOST and whether the screwdriver was tested under a voltage higher than 1000 volts, and also take into account which manufacturer of screwdrivers is better.

For those craftsmen who constantly use this type of screwdriver, you should know that dielectric screwdrivers should be taken from time to time to check their performance. This is required in order to exclude all kinds of injury when working with electricity. Do not forget about this advice, since in the course of work, wear of the protective coating often occurs.
