During overhaul or cosmetic repairs, there is always a need to use improvised tools. A screwdriver must be in almost every home, because this power tool significantly saves labor and time.
A screwdriver is an electromechanical tool with which you can twist and twist self-tapping screws, as well as drill small holes. The screwdriver is not one of the three most necessary tools in the household, it is not a fact that there is a place for him in the top five. But if you decide to arrange a major overhaul, during which, as you assume, it will be necessary to tighten more than a hundred different screws and screws, the presence of a screwdriver will significantly save not only your time, but also your nerves. In addition, the relatively low price of this tool makes it very affordable.
What are screwdrivers?
A key characteristic of a screwdriver is its torque. This indicator indicates what material you can screw a screw into. The higher this indicator, the more dense the material can be.
According to the method of power supply, screwdrivers are divided into cordless and network. Networks are obviously more powerful and can work without interruptions, while they have less weight. However, there are disadvantages:
- Dependence on the availability of the mains and the length of the power cable;
- the wire interferes with active movements;
- network tools are more overall;
- Network screwdrivers, as a rule, do not have a drilling function.
The advantage of a cordless screwdriver can be attributed only to mobility. However, it also has its drawbacks:
- having smaller dimensions, the cordless screwdriver weighs more due to the battery;
- this tool is inferior in power to the first option;
- time limitations in work (you have to wait for the battery to charge or buy a spare battery);
- a cordless screwdriver is more expensive than a network analogue.
