For those who prefer to do simple work in the apartment themselves - for example, to collect a piece of furniture or hang a shelf on the wall, sooner or later the question arises - how to choose a screwdriver for the house.
This versatile tool helps not only to tighten, but also to unscrew the self-tapping screws and screws, which often “stick together” and do not lend themselves to the usual “hand-held” screwdriver. It is worth the screwdriver for a home more expensive than a conventional screwdriver, but it justifies itself by a significant saving of time and effort. In addition, some models of screwdrivers allow drilling holes in various materials.
Types of screwdrivers
Tools of this type can be divided into two main types:
- For professional purposes;
- For domestic purposes.
Professional models are chosen for frequent use. They have a high rotational speed - up to 1300 revolutions per minute, and high torque - up to 130 Nm. This allows you to develop considerable effort, and drill holes in wooden parts and even brick walls.
Household models choose to use from time to time. Rotation speed is less - up to 500 revolutions per minute, torque does not exceed 15 Nm. This is quite enough to screw the screw or unscrew it, disassemble the lock, to assemble the furniture. For household chores, the possibilities that household screwdrivers provide are sufficient. In addition, the cost of screwdrivers for the house is much less than professional.
How to choose a screwdriver for home mains or battery?
Screwdrivers are divided into two main groups:
- Network;
- Rechargeable.
Both have their strengths and weaknesses. Network models are quite powerful, they can work for a long time, without fear that at the most crucial moment the tool suddenly turns off. It does not have to be put on reloading, which is especially important if there is a long-term use of a screwdriver. Also, you will not encounter a situation when you urgently need a tool - but you cannot use it, because the battery is low.
The main drawback of home network screwdrivers is the cord with which you are “tied” to the socket. It is impossible to do work where there is no electricity, and the front of work should be as close as possible to the outlet. In addition, it is not always convenient to work when a long cord leaves the instrument.
Battery models are not inferior in power to the mains, and they are superior in terms of ease of use. Indeed, the cord does not come out of the handle of the device, which can interfere with operation; you can use the tool even in the absence of a power supply network.
The main drawback is the limited operating time, and, in addition, the need to charge the battery. If you decide to choose a screwdriver for a battery-powered home, you need to consider that their work depends on the type of batteries.
Metal-hybrid. Of the benefits can be noted the possibility of using at temperatures below zero. Minus - you need a full discharge before you start charging again, otherwise the battery capacity and, consequently, the time it will be used will decrease with time.
Nickel-cadmium. Can work at low temperatures, in addition, withstand high currents during charging and discharging. The minus is the same as that of the metal-hybrid: it is necessary to completely discharge the battery before putting on charge.
Lithium Ion. Batteries of this type are the most powerful. In addition, they can be recharged without fear of reducing capacity. Minus - you can work only at positive temperatures. In addition, for screwdrivers equipped with lithium-ion batteries, the price is much higher.

For a non-specialist it is difficult to take into account all the nuances, choosing such a technically difficult thing as a screwdriver. Therefore, be guided by expert advice:
- Batteries in cordless screwdrivers can vary in power from 9.6 to 24 volts. More power means more power, but weight increases. Choose according to this circumstance.
- Rotational speed of 500 revolutions per minute will allow to assemble furniture without any problems. To drill concrete, select a minimum of 1200.
- Well, if the screwdriver for the house will be equipped with the support of the fixed power at low speeds - such a tool is safer to use.
- Any tool should be comfortable; in a screwdriver, convenience will be ensured by a handle of sufficient length, with a rubberized surface. Check if he is well in the hand.
- The switch that changes the direction of rotation should be easy to use - try clicking them.
- An additional plus of the screwdriver is the presence of interchangeable nozzles (bits), which allow working with screws, self-tapping screws and other fasteners.
