How to choose a dielectric screwdriver set?

A screwdriver is a necessary tool in everyday life, because we are surrounded by things with fasteners made of screws and screws. Dielectric screwdrivers are indispensable when working with devices based on various microcircuits that operate on electricity. They protect the person and the device from electrostatic shock. Let's consider how to choose a set of such tools.

If in order to quickly repair a broken electrical appliance at home with your own hands, you need one, maximum two screwdrivers (straight or cross-shaped), then for people whose vocation (profession) is the installation / repair of various electrical / electronic networks and devices, you need a professional a set of dielectric screwdrivers. The use of such tools in work with electrical devices and networks operating under high voltage (up to 1000 V), guarantees the safety of the master, because the insulating coating of such screwdrivers does not allow electric current to pass through.

In addition, the convenience of the sets also lies in the fact that:

• they often have a special indicator that serves to determine the phase in the power grid;
• the presence in them of a variety of shapes and sizes of devices for almost all occasions;
• the sets are usually placed in special cases or handbags-cases, in which each type of instrument has its own place - either a figured depression or a loop fastener.

The most important requirement for dielectric screwdrivers is their safety, that is, the ability of the insulating material not to pass an electric current. According to GOST, all electrical tools with single-layer insulation used for work under voltage must be regularly tested for electrical safety.

The working part of the tool must be made of high-quality steel that meets the requirements of GOST, the handle must be made of synthetic polymers of sufficient density, and the insulating material must be made of low- and high-density polyethylene.

Each dielectric tool must be marked with a maximum operating voltage - 1000V or 1000V.

On screwdrivers or packaging, the manufacturer must indicate the dimensions of the tool - the length, thickness of the flat slot or the number of the cross-shaped part.

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 is in the reduced weight of the set, the 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 the 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 the 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 no longer safe to work with them.

Dielectric tools SHTOK, both in single and in stacked 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 makes them more convenient to 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 sets 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.
