The electric tool is an indispensable assistant in the implementation of various repair and construction works. Drills, punchers, screwdrivers, chippers, planers - and this is not a complete list of everything that you may need. But so that the work does not bring unnecessary disappointments, it is necessary to approach the choice of power tools with all seriousness and responsibility.
Instruction manual
1
First of all, it is worth deciding on what type of work you need a power tool - professional or amateur. Professionals from their own experience know that it is often required to use the tool for a long time without stopping, and at critical loads. Not every model can withstand such work. Therefore, if repair and construction is your profession, you must choose the first type of tool. Otherwise, it is better to opt for amateur models. Moreover, the price of them is not so high.
2
Power tools can be powered by a built-in battery or an AC source. A device that can be connected to an outlet costs less, but it can only be used close to a power source. Extension cords are used to expand the application space, but in this case you need to be especially careful. The fact is that low-quality extension cords due to a power surge can cause a breakdown of the device.
3
In turn, a power tool with a built-in battery gives freedom of movement. In addition, it can work in non-electrified places. On the other hand, the duration of such devices is not so high, and the battery fails over time. If the need for a power tool is rare, it is undesirable to purchase a model with a built-in battery. The latter may well fail, while the device is gathering dust on a shelf.
4
The next point that is important to pay attention to is the safety of the tool. Two points should be noted here. Firstly, the reliability of electrical insulation. It is best to choose tools with double insulation (the first layer is the internal electrical elements, and the second is the tool body). Such models can be distinguished by a special marking - a double square.
5
Secondly, it is protection against accidental start-up. So that the tool does not accidentally turn on and thereby does not harm health - yours or those around you - it must be equipped with an additional button. When it is pressed, the start of the device is confirmed.
6
Separately, it is worth mentioning the functionality of a power tool. Newcomers are often advertised for multi-profile models, but in vain. Different operations require different design features of the tool, often completely opposite, and therefore one device is not able to do all kinds of work well. If you still want to buy a multi-profile model, opt for one that will have few functions.
7
When choosing a power tool, you must pay attention to the manufacturer and point of sale of these products. Always consider products only from trusted brands such as Hitachi, Bosch, AEG, Krss, Metabo, Makita, etc. It must be remembered that little-known manufacturers are not able to guarantee the high quality of their products. In addition, in the event of a product breakdown, warranty service for such a tool can be a big problem. In turn, when working with devices produced by the above brands, such problems will not arise.
8
Power tools should be bought only in specialized stores, not in markets. In addition to the obvious advantages of the store (for example, the ability to replace defective goods, warranty service), you will also receive advice from a qualified seller.
9
To choose a quality power tool, take several devices of the same model and turn them on one by one. You should choose one in which the sound of the work will be more even, without knocking. Then start it again, stop it again and listen to the sound at the moment of termination of work. This sound should be smooth, gradually fading. Also see how the device stops rotation. It should do it smoothly. If the power tool stops abruptly, this means that the connections in the mechanism are very tight and that too much effort is applied to rotate them.
10
Choosing the right power tool is not an easy task, but it can be done. It is only necessary not to forget about all the above recommendations. And remember that buying a quality tool is only half the battle. The product must also be operated and stored correctly. If all these conditions are met, it will last you a long time.
Useful advice
Give preference to a power tool with a soft start and maximum speed control.
A good appliance should have a torque limit clutch. Due to this, with an unacceptable load, the tool will stop its work.
