The household cordless screwdriver will be a useful helper. With it, you can assemble furniture, install drywall boards, screw in skirting boards and much more. Arriving at a construction supermarket or store, you can see a wide range of tools from various manufacturers. Let’s find out how to choose a cordless screwdriver and what you need to pay attention to when buying it.
From the very beginning, decide for what purpose you need it. For home use, an ordinary tool with modest technical characteristics is quite suitable. In this case, you can avoid significant costs. If, by means of a tool, you drill metal or walls, then its technical characteristics should be more impressive, as well as the price.
What to consider when buying a screwdriver?
If the tool is cordless, then it is important to consider the type of battery. They are of three types:
• Nickel cadmium;
• Metal hybrid;
• Li-ion.
Metal-hybrid are the cheapest, but their discharge time is short. But lithium-ion batteries are the most expensive and reliable. Therefore, before buying a screwdriver, try to find out what type of battery it uses.
The next indicator that deserves our attention is the battery power. It is in the range of 9.6-24 watts. The higher it is, the better: the tool will be able to perform the most complex work and screw the screws into problem areas. The reverse side of a powerful screwdriver is its significant weight, because a weighty tool is not so easy to work.

An important characteristic is the torque. For domestic use, 10-13 Nm will be quite enough, but if you want to successfully make holes in the wall with a tool, then 30-40 Nm is enough for you. In some devices, the torque reaches 130 Nm.
When buying a screwdriver, it is important to consider the speed of rotation. If the tool will be used only for twisting self-tapping screws, then 400-500 rpm will be enough, but for performance of more serious repair work this indicator should be at least 1200 rpm.
These are the main characteristics that you must consider before buying a cordless screwdriver. Remember them when choosing a tool, and you will not have to lament in the future that you have purchased the wrong thing.
