How to choose a screwdriver for home?

This universal tool helps not only to tighten, but also to unscrew the screws and screws, which often “stick” and are not amenable to the usual “manual” screwdriver. A home screwdriver costs more than a conventional screwdriver, but it justifies itself by a significant saving of time and effort. In addition, some screwdriver models allow you to drill 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 choose for frequent use. They have a high rotation speed - up to 1300 rpm, and high torque - up to 130 Nm. This allows you to develop significant efforts, and drill holes in wooden parts and even brick walls.

Household models Choose to use from time to time. The rotation speed is less - up to 500 rpm, the torque does not exceed 15 Nm. This is enough to screw in a screw or turn it out, disassemble the lock, assemble the furniture. For homework, the capabilities provided by household screwdrivers are quite enough. In addition, the cost of home screwdrivers is much less than professional.

How to choose a power or cordless home screwdriver?

Screwdrivers are divided into two main groups:

• Network
• Rechargeable.

Both have strengths and weaknesses. Network models quite powerful, they can work for a long time, without fear that at the most crucial moment the tool will suddenly turn off. It does not have to be put on recharge, which is especially important if you have to use the screwdriver for a long time. Also, you will not encounter a situation when you urgently need a tool - but you can not use it, because the battery is low.

The main drawback of home power screwdrivers is the cord with which you are “tied” to the outlet. To do work where there is no electricity, it will not work, and the front of the 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 tool.

Battery Models in terms of power they are not inferior to network ones, but in terms of ease of use they surpass them. Indeed, the cord does not leave the handle of the device, which may interfere with operation, you can use the tool even in the absence of an electrical outlet.

The main disadvantage is the limited operating time, and, in addition, the need to charge the battery. If you decide to choose a cordless screwdriver for your home, you need to consider that their work depends on the type of battery.

• Metal hybrid. Of the pluses, the possibility of using at temperatures below zero can be noted. Minus - a complete discharge is required before you start charging again, otherwise the battery capacity and, consequently, its use time will decrease with time.
• Nickel cadmium. They can work at low temperatures, in addition, they withstand high currents when charging and discharging. The minus is the same as that of metal hybrid: you need to completely discharge the battery before putting it on charge.
• Li-ion. Batteries of this type are the most powerful. In addition, they can be recharged without fear of lowering capacity.Minus - you can work only at positive temperatures. In addition, for screwdrivers equipped with lithium-ion batteries, the price is much higher.

Useful tips when choosing a screwdriver for the home

It is difficult for a non-specialist to take into account all the nuances, choosing such a technically complex thing as a screwdriver. Therefore, focus on the advice of specialists:

• Batteries in cordless screwdrivers can have different capacities - from 9.6 to 24 V. More power means more options, but weight is also increasing. Choose with this in mind.
• A rotation speed of 500 rpm will allow you to assemble furniture without any problems. In order to drill concrete, select a minimum of 1200.
• It is good if the screwdriver for the house is equipped with support for fixed power at low speeds - such a tool is more reliable in use.
• Any tool should be convenient, in a screwdriver convenience will provide a handle of sufficient length, with a rubberized surface. Check if he is “lying” well in his hand.
• The switch with which the direction of rotation changes should be convenient for use - try to “click” it.
• An additional plus of a screwdriver is the presence of interchangeable nozzles (bits) that allow you to work with screws, self-tapping screws and other fasteners.
