A screwdriver is an excellent device that is useful for working in the house, as well as for professional manipulations. In this article we will tell you how to choose a screwdriver depending on your requirements.

How to choose a screwdriver: what to look for?

Features of choice:

Before purchasing such a technique, you need to decide why you are buying it. If a screwdriver is needed for home use, it will be rarely operated, that is, to fasten the shelf or collect a small nightstand, a household device with a low power and speed of 400-500 rpm is quite suitable.
Such a speed of rotation will be quite enough. But such power is not enough if the holes in the wall are drilled. Especially if it is made of concrete, quite stiff. There are also professional screwdrivers.
They can not only tighten the screws, but also make holes in a hard concrete wall. In addition, such products are designed for constant use by professionals. Ideal if you are engaged in professional assembly of furniture or gypsum concrete structures, when installing suspended ceilings. The speed of rotation in such devices is 1400-1500 rpm.
This is a fairly high speed that will allow you to drill a hole in the concrete wall. When purchasing a screwdriver, it is worth paying attention to how it works from the network, or from the battery. If you are not going to leave home from home and a screwdriver is needed to work in an apartment or house, then you can not bother, purchase the one that works from the network. It has a number of advantages.

Advantages of a stationary screwdriver:

No need to constantly recharge
The power of the device is quite high and does not sit down over time, as the battery charge decreases

But such products are a lack - lack of mobility. That is, they cannot be transferred somewhere to nature, for work or manufacturing some garden shops. Everything will have to be done in the house or in the garage, where there is electrical wiring, with the ability to connect to the mains. If you often work outside the city, and a screwdriver is necessary in order to work in your own house, make hives, shed and or some kind of garden furniture, then a screwdriver on the battery will be an ideal option.

How to choose a screwdriver: selection of a battery device

When acquiring such a miracle of technology, pay attention to the battery itself, and from which it is made, as well as in which you will work.

Batteries for batteries, types:

Nickel-metallhydride. Such batteries work perfectly in low temperatures, that is, in the cold. But one of the disadvantages is the presence of a memory effect. That is, if you do not completely discharge them completely, only recharge them in time, the battery capacity decreases over time. Therefore, sometimes it is necessary to completely discharge the battery and charge it to the end. Such manipulation will maintain a fairly high battery capacity.
Ion-literary. Some of the best batteries that do not have the effect of memory and do not reduce the container over time. But these batteries have a significant drawback. They cannot work at low temperatures, that is, in the cold. Therefore, it makes sense to purchase such a battery if you work at home or at a summer cottage in the summer.
Nickel-cadmium. Also good batteries for work at low temperatures, but they have several drawbacks. They charge for a long time, quickly discharged. At the same time, they have a memory effect, over time, the capacity of such a battery decreases if you do not completely discharge it and charge it to the end.

How to choose a screwdriver: apparatus rating

When acquiring, you should pay attention to the presence of removable bits. Scurgets are considered ideal, in which there are many interchangeable nozzles that allow you to tighten screws, self -tapping screws with different heads. In this case, you do not have to purchase additional bats.

Apparatus rating:

The screwdriver should have a long rubberized handle, which comfortably lies in the hand. Therefore, before you buy the device, you need to take and try, hold in your hand or even ask to screw something in the store.
Now there is a service that allows you to screw several screws into the drywall plate in order to check how the device works, how powerful it is and whether it lies in the hand.
An important aspect is the power of the device, the higher it is, the harder the device, but its functionality is also much higher. That is, such a device has a large number of functions, it will come in handy for you to perform almost all home and professional work. Please note that some screwdrivers, especially the cheapest ones, are not equipped with a reverse, that is, rotation in the opposite direction.
Therefore, it will be difficult for you to unscrew the screw without using a screwdriver. Professional devices are equipped with such a function, so they can not only be tightened, but also unscrewed. This is the main advantage when dismantling furniture.

Which screwdriver to choose: we analyze the torque, equipment, cost

Features of choice:

When choosing the device, it is also worth focusing on torque, that is, how much and with what effort the screwdriver cartridge is spinning. For home use, a great option is models with a torque of 30-40 N/m. With their help, you can collect furniture, screw it up, twist the bolts, collect products from drywall and plastic, and independently carry out repairs in the house.
Medium power - devices with a torque of 20 N/m. Simple and affordable, inexpensive, but they have a small torque, so you should not count on the implementation of serious work.
The smallest and cheapest are batteries, their torque is 10 n/m. Accordingly, the performance of the work is very limited. Suitable in order to collect a simple bedside table, screw the plastic on the balcony.
Professional models have a torque of 120 N/m, respectively, they are 3 times more powerful than household apparatuses. Therefore, with the help of such devices, you can drill holes, work for 8 hours, 5 days a week. Such devices are hardy and created for permanent, many hours of work.

Of great importance is the price category of the device, it directly depends on the torque, power, weight and functionality. The more functions he has, higher power and more weight, the more expensive the device. The most interesting thing is that the difference is quite tangible, can exceed the cost of the most inexpensive and professional devices by 10, and even 20 times.

If you need a home device, do not overpay. It is better to purchase a medium -power apparatus with small functionality. He will perfectly cope with simple homework, which you will rarely perform.
