In this article we will try to answer a very common question: which screwdriver is better to buy. But first, consider where the screwdriver is used. Then we will understand what we need to get. This is a power tool for tightening or unscrewing screws, screws, in short, various fasteners. With it, you can drill various materials - wood, metal, brick, concrete, plastic. But the main professional use is furniture production. We will do a review of the main indicators of the work of a screwdriver for use at home, in the garden, in the garden, in the country, to make it easier for you to choose the right tool.
The screwdriver itself is a fairly simple tool, there are no special design differences between the models, the principle of operation is the same for everyone.
There are three main characteristics by which you need to choose which screwdriver to buy:
- manufacturer,
- power,
- type of battery.
Which firm is best to buy a screwdriver
There are a lot of manufacturers. Their main difference is that well-known manufacturers have a rather serious quality system, but at the same time they invest quite a lot of money in advertising. Accordingly, their products are of high quality, but more expensive, sometimes even unreasonably.
Less well-known manufacturers invest less in advertising, but their quality will be weaker. So choosing a tool by manufacturer is a choice between quality and price.
Power of a screwdriver, which is better
The second parameter that you should pay attention to when choosing is power. It is measured in Newton meters (nm). It’s simpler to say this: the stronger the “torque”, the stronger you can hold the nozzle or deeper, drill a hole wider.
For homework, usually when choosing in a store, screwdrivers of three capacities are asked (according to everyday estimates):
- more powerful
- how everyone takes it, that is, ordinary,
- anyway, which one - just to spin.
Let's start with the third parameter. This is a regular cordless screwdriver. Power - about 10 nm. She can unscrew or tighten small fasteners, repair children's toys or loosely clamped furniture bolts.
According to the second estimate, this is a regular screwdriver with a torque of up to 20 nm. They can already unscrew, twist any fasteners or drill something small. But basically tools with such data are used only when you need to unscrew or twist something.
According to the first parameter - "more powerful" - this is a power tool with a torque of 30-40 nm and above. They can unscrew, twist everything you need and plus use it as a drill.
By the way, power is not always indicated in Newton meters. There is another unit of power measurement - voltage. True, this is an outdated name for the unit of measure of electric potential, but it is sometimes used. When choosing a screwdriver, focus on the voltage value - the higher it is, the more powerful the tool.
What type of battery to choose for homework
There is another parameter that you can’t do without knowing when buying - the material used in the manufacture of the tool battery.
Batteries are of the following types:
Honestly, for a home electric screwdriver, the battery capacity does not matter much. There are models with a capacity of 1A (amperes), 1.5A, 2A. If you do not work with the tool every day five days a week for 6 hours in a row, then this parameter is not very important for you. Even if the battery suddenly runs out, it will not be a big problem to put it on recharge.
Each tool has additional options:
- reverse - switching the direction of rotation, thanks to this option you can twist or unscrew;
- keyless chuck, allowing at the moment to clamp or, conversely, remove the nozzle;
- adjustment of the clamping force or electronic brake, that is, if you clamp the nozzle in the chuck, the screwdriver itself will stop.
Options such as backlight, a magnet for bits and nozzles, a belt hook are not available on all screwdrivers, but they are not so important for working at home.
We have listed the main parameters by which we will choose a screwdriver for the home.
Repeat them again.
The main parameters are:
- producer - value for money;
- power - Newton meters, torque or voltage;
- type of battery - it depends on how quickly it will be discharged, and how to charge it.
The remaining indicators of the screwdriver for home use are not particularly important.
Enjoy the shopping!
