Overview of cordless drills. The best perforators cordless

Installation work on construction sites, in residential and industrial environments, often involves the implementation of mechanical operations with solid materials. These include concrete, metal, brick and even stone. The solid structure can not be cut with a conventional drill and especially saws. Qualitatively, such work can only perforators, battery versions of which are becoming more popular. True, models differ in many indicators, which complicates the choice of the optimal option.

Features of battery punchers

As in the case of network guns, the dignity of their battery counterparts is primarily determined by the impact energy. In a simple way, all models of this group are divided into household devices and professional ones - accordingly, the impact energy is up to 3 J and more. From the standpoint of efficiency, the best cordless drills should have a wide range of drilling capabilities in terms of hole sizes.

The main differences relate to the energy supply system. The device is powered by a small battery pack, which allows you to work in a distance from the outlet. Therefore, in addition to the power potential and drilling parameters, autonomy indicators are among the important characteristics. On average, a battery tool of this type is capable of operating for 50-60 minutes. Thus charging takes the same time. The optimal solution is to purchase a model with two battery packs. While one of them is charging, the second one can be plugged into the outlet - but, of course, if such an opportunity exists on the site. Anyway, to determine the best option follows the combination of characteristics. This will help to make an overview of the battery hammers presented below.

Model DHR202RFE from Makita

The model provides the user with 3 operating modes, among which standard drilling, chiselling and impact perforation. Especially for the tearing off of tile materials, the developers provided for a special turn of the bit. The device can not be called high-power, but its power capacity is sufficient for most typical construction and repair operations. Actually, the main advantages of this model in another. Like all Makita rechargeable battery punchers, this version is provided with a wide range of functions that allow you to adjust the parameters of the workflow. For example, the operator can use the reverse stroke, easily manage the disengaging clutch, connect the backlight to the process, and also regulate the engine speed. An important constructional addition was the introduction of the SDS cartridge, which allows the replacement of the cutting element with one hand.

Model R18SDS-L25S from Ryobi

This unit is also able to work in different modes, has a wide functionality, but it also has some unique qualities. So, the developers envisaged the possibility of using its battery for all Ryobi battery models. That is, one battery pack is suitable for the entire arsenal, which is planned to be used on the construction site. This decision justifies itself, if one person works. Otherwise, the battery hammers in this series offer the same features - backlight, reverse stroke, speed adjustment and a convenient drill replacement system. However, we can note one more advantage in this puncher. While the model corresponds to the more famous "Makita" design by technical parameters, it costs cheaper - 14 thousand rubles. Against 22 thousand.

Model GBH 18 V-EC from Bosch

Unlike Japanese designers, German developers have far gone from the functions that have become habitual in professional construction and are actively learning new directions. The results of this work were embodied in the model GBH 18 V-EC, which received an innovative brushless motor. All experienced users of hand power tools such as drills and screwdrivers know how important it is to replace carbon brushes that extend the operating life of the power plant in a timely manner. So, Bosch cordless drills relieve this need. Together with this, the creators of the device did a good job of improving the controls, providing an ergonomic two-position toggle switch for switching the operating modes.

How to choose the best model?

It is necessary to take into account first of all the operating conditions of the perforator. It may be necessary to have a dust extraction system, LED backlight, the possibility of setting the optimal operating mode, etc. If you need a universal assistant for working with walls and partitions, then you should prefer the model from "Makita". It is a reliable and functional device that can easily perform basic operations. If the power is not of paramount importance and it is planned to use the instrument in different conditions, then it is worth choosing a Ryobi battery puncher, since it has the most efficient power supply system. The development of the company Bosch is suitable in both cases, but also relieves the owner of the hassle in the process of maintenance.

Conclusion

With the regular use of power manual tools, professional builders are increasingly focusing on the working resource of the element base. This is due to the fact that the repair of a battery puncher requires serious investment and only in rare cases can be performed independently. Typically, such actions are reduced to disassembly of the device and cleaning of functional elements, the mechanisms of which are clogged with dust. In order to minimize the need for such activities, it is recommended to pay attention to the properties of the enclosure from the point of view of dust permeability. From the models described above, only the instrument from the German manufacturer Bosch possesses such protection. This device is also balanced in terms of power characteristics, and it is simply convenient in working manipulations.
