Features of the choice of cordless screwdriver for home


A good cordless screwdriver will help to make repairs at home or at the dacha, and also help out in the most unexpected situations. It should be for every man who considers it his duty to keep his house in order. However, it is impossible to choose the first model on the market, as well as to advise all the same option. The choice of a screwdriver for a house largely depends on the tasks that are put before it.

Household or professional?

Cordless screwdrivers, like many other tools, are divided into two types:

  1. Professional. They have great power and are able to cope with a huge number of tasks, but they require constant use. If you only need a drill a few times a year, do not buy an expensive tool for repairmen. Firstly, you do not use all its potential (why give money for something that is not useful to you?), And secondly, if you choose a model that is too powerful, it will simply fail before the time.
  2. Household. Perfectly suitable for home or cottage. Some of them have good characteristics and are close to professional ones. Only, unlike the latter, they are designed for a small load and, if properly stored, can serve a long time.

In this article we will look at the household models available on the market.

The battery is the main selection criterion

Cordless screwdrivers are manufactured with one of three types of batteries:

  • Li-on (lithium);
  • Ni-MH (nickel-metal hydride);
  • Ni-Cd (nickel-cadmium).

To properly choose the right model for the house, you need to get acquainted with their pros and cons. For a good comparison, we have compiled a table for you.

Li-on (lithium)

Ni-MH (nickel-metal hydride)

Ni-Cd (nickel-cadmium)


  • can be recharged at any stage;
  • environmentally friendly and safe;
  • are charged much faster than other species;
  • light and small in size;
  • can withstand up to 3000 cycles of charge and discharge.


  • less weigh compared to Ni-Cd;
  • are safe for ecology;
  • they do not need to be completely discharged before charging.


  • low cost;
  • can work and be charged at any temperature (even in winter on the street);
  • can be stored for a long time;
  • endure about one and a half thousand cycles of charge and discharge;
  • shelf life up to 5 years.


  • the highest cost among other species;
  • poorly tolerate negative temperatures;
  • shelf life up to three years.


  • compared with Ni-Cd higher cost;
  • can withstand up to 1000 cycles of charge and discharge.


  • Before charging, it must be completely discharged (otherwise the drill will fail beforehand);
  • large dimensions and weight;
  • long charge;
  • harmful to the environment and human health.

Important: Before choosing a new screwdriver, keep in mind that lithium batteries are designed for frequent use use, so if you plan to take the instrument in your hands infrequently, give preference to another kind of battery.


Screwdrivers with nickel-cadmium batteries will last much longer, and at the price they are the most profitable. However, remember that it is better to store them completely discharged, and a new charge takes time.


You can choose a nickel-metal hydride battery - it's a newer kind of battery. They are faster loaded and do not require a full discharge for storage, but are slightly more expensive.

Regardless of the type of battery, you should pay attention to its capacity and voltage:

  1. The higher the capacity indicator (A * h), the longer the drill is able to operate autonomously. However for the house it is quite possible to manage and the simple apparatus.
  2. The higher the voltage (measured in volts), the greater the power is able to demonstrate a screwdriver. This indicator is also associated with a soft and hard torque.

For the house or villa it will be correct to choose the average model for these parameters. However, if you very often do repairs, take a semi-professional device.


From the batteries, we gradually switch to power, since it directly depends on the type of battery selected. The power reflects two main parameters:

  1. Soft torque - shows how the screwdriver will work as a screwdriver. The rotation speed of good models reaches 350 rpm.
  2. Hard torque - shows how the drill will work. In the drilling mode, a good machine accelerates to 1000 and higher RPM.

It is better to choose the unit with the ability to smoothly adjust the rotation speed: this will allow you to avoid mistakes during repair. If you need intensive work with hard surfaces, buy a powerful cordless screwdriver.


Additional functions

Various additional features make the use of the tool particularly convenient:

  • The impact mechanism will help when working with a stone or brick wall;
  • the impulse is useful for unscrewing the stuck self-tap in the case when the puncher has not coped;
  • The backlighting is actual when it is necessary to repair it in a poorly lit room. It will be correct to choose a model with a light bulb above the battery pack, but not above the start button;
  • ergonomic handle and compact size will greatly facilitate the use of the device;
  • you will also need additional attachments (it is better to choose a multifunctional drill).

Of course, it is impossible to recommend a universal model: someone needs a cordless screwdriver once a year, and someone uses a drill almost every morning (everyone in a block of flats has his own favorite mysterious neighbor with drill). Choose a tool based on your personal interests and needs, and then you will certainly be satisfied with the purchase.
