Screwdriver – how to choose the best one


How to choose a screwdriver

A screwdriver in a very short time became a real helper in everyday life and on a construction site. Without this electric tool, the work becomes less efficient, it takes a lot of time and effort to complete even the simplest tasks. Hand tools are in certain demand. But electric opens up much more possibilities. The only problem is that a huge assortment of screwdrivers can be confusing, what equipment should I prefer?

Wired or cordless screwdriver

A cordless screwdriver is less in demand and this can be understood. You always remain attached to the outlet, it is very difficult to perform high-altitude work. Even if you use a very long cable and get a certain mobility. The wire will always be with you, it will always interfere. Therefore, if you have financial capabilities, it is better to take a cordless screwdriver.

Of course, the battery must be charged, but if you buy a spare battery, then there will be no problems with this. You have been working with one battery for several hours. And the second has already managed to charge and is ready for replacement. Therefore, professionals recommend buying a cordless tool, it is more practical and convenient.

Power screwdriver

It all depends on what purpose you are buying the tool. If for domestic tasks, then you do not need a lot of power and torque, but if you need to carry out complex professional work. It is better to spend more money on a productive screwdriver. Power directly depends on what operating voltage the battery gives out:

A simple household tool works with a voltage of 3-6 V. This is enough to screw the screws into soft surfaces. Batteries with a voltage of 10-15 V allow you to drill wood, drywall and plastic. The battery with a voltage of 18 V allows you to easily work with solid wood.

The more power, the more versatile and functional tool you get. But you must understand that an increase in power directly leads to an increase in cost. So it is better to think and make the choice of the most suitable screwdriver for your tasks. If you are not a builder, then you do not need a professional power tool.

Battery type

If you have preferred mobility and abandoned the electric cable, then you need to pay attention to the type of battery. It must power the tool for a long time and at the same time constantly give out the rated voltage. Also, how quickly and efficiently the charging will be carried out depends on the type of battery. There are 3 types of batteries:

Batteries Li-Ion (lithium-ion) is the most optimal choice, they give the necessary power for work, charge quickly, have the largest charge cycle (up to 3000 times), can work on a single charge for a very long time. But at the same time they work poorly in the cold.
Batteries Ni-Cd (nickel-cadmium) – these batteries show themselves well during operation, even in cold weather, charge cycles of 1500, the voltage is quite high. The disadvantage is that the batteries lose their charge too quickly, and it takes about 7 hours to fully charge. For professionals, this option is not suitable, but for everyday tasks it will work fine. Keep batteries in a discharged state.

Batteries Ni-MH (nickel-metal hybrid) are a very good option for everyday life. They work on a single charge for a very long time, but they also charge for a long time. The disadvantage is that there are only 500 charge cycles, which is very small for professionals.

Additional functionality

While working, you will face various tasks, so the tool should provide you with simple solutions. For example, the presence of bit holders on the housing allows you to quickly change nozzles and thereby significantly increase the efficiency of your work. This is a trifle, but without it, the bits are constantly lost and quickly change them will not work.

Some screwdrivers have a power adjustment wheel in their design. This is a very useful control that makes it possible to choose the optimal mode of operation for certain tasks. In order to make a hole in a solid tree, more power is needed, but in order to screw a screw into a drywall, a lot of effort is not needed, so you can reduce productivity. Also, in some models it is possible to fix the tool in working condition and not to pull the trigger, which can save a lot of your strength.

If there is a special mount on a building belt, then this will also be a great advantage for professionals. The bottom line is that when carrying out high-altitude work, you must always keep a heavy screwdriver near you, but getting down every time is not the best option. On construction belts there is a special place for attaching a screwdriver, if such a function is provided on your tool, then the efficiency and convenience of
