Overview of cordless drills. The best perforators cordless

Installation work on construction sites, residentialpremises and in factories often assume the performance 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. Simply, all models of this group are divided into household devices and professional - respectively, the impact energy is up to 3 J and more. From the point of view of working capacity, the best cordless perforators should have a wide range of drilling capacities in terms of hole sizes.

The main differences concern the systempower supply. The device is powered by a small battery pack, which allows you to work at a distance from the outlet. Therefore, in addition to the capacity 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 socket - but, of course, if such an opportunity is available on the site. Anyway, to determine the best option follows the set of characteristics. This will help to make an overview of the battery hammers presented below.

Model DHR202RFE from Makita

The model provides 3 workstations to the usermode, among which standard drilling, chiselling and impact perforation. Especially for the tearing off of tile materials, the developers also 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 disengagement clutch, connect the process to the process, and adjust the engine speed. An important structural 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 capable of operating in differentmodes, is endowed with wide functionality, but at the same time it has some unique qualities. So, the developers have 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 setting and a convenient drill replacement system. However, one can note one more advantage in this puncher. While the model corresponds to the more famous development of "Makita" by technical parameters, it costs cheaper - 14 thousand rubles. against 22 thousand.

Model GBH 18 V-EC from Bosch

Unlike Japanese designers, Germandevelopers are far away from the functions that have become habitual in professional construction and are actively developing 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, perforators are rechargeable Bosch brands 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 conditionsoperation of the perforator. It may be necessary to have a dust extraction system, LED backlight, the possibility of setting the optimum operating mode, etc. If you need a universal assistant in 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 necessary to choose a battery punch from Ryobi, since it has the most efficient power supply system. The development of Bosch is suitable in both cases, but also relieves the owner of the trouble in the process of maintenance.

Conclusion

With regular use of power manualtool, professional builders pay more and more attention to 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. As a rule, 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 measures, it is recommended to pay attention to the properties of the enclosure from the point of view of dust-tightness. Of the models described above, only the tool from the German manufacturer Bosch possesses such protection. This device is also balanced in terms of power characteristics, and is simply convenient in working manipulations.
