The first experience of manufacturers on the use ofaccumulators in a hand-held construction tool found many advantages of this solution over network analogs, but showed obvious shortcomings. In particular, autonomy was provided at the expense of the power potential, so the batteries were more often used in the lower segment of the household instrument. However, today, thanks to the optimization of batteries and chargers, the developers have successfully used this principle of power supply, even in shock electric relays. For example, the Hitachi perforator, presented on the market and in professional modifications, does not lose in power to many network models of its class.
General information on Hitachi rotary hammers
The manufacturer relies on organica combination of high power capacity, ease of operation and energy efficiency of this product. In terms of applications, devices are also divided into household and professional. The power of the apparatus is sufficient to perform work with concrete and brick - only the parameters of the holes that form the Hitachi nozzles differ by and large. The rotary hammer rechargeable of this line is also provided with new design solutions. Almost all models allow the operator to set limits on the depth of drilling, which favorably affects the accuracy of the operations performed. A variety of modes also optimizes the process - the user can adjust the settings based on the requirements for the result and the characteristics of the material being processed.
Reviews about the model DH18DL
One of the lightest and compact modelsperforators in the line of the Japanese manufacturer. Users note that the device is easy to handle and at the same time provides a good impact force. Nevertheless, one should not count on high power. According to the owners, the thick, high-strength walls of such a machine are beyond the power. But with simple household drilling operations in hard surfaces, the Hitachi perforator in the DH18DL executes without difficulty. The possibility of changing the impact energy index is also underlined. So, for very simple tasks, the user can use the economical mode of operation, which also leaves a minimum of dirt. And on the contrary, the reinforced rigging makes it possible to drill large holes. Convenient controls take a minimum of time in the configuration, which is also attributed to the pluses of this modification.
Reviews about the model DH24DV
The model can be attributed to full-fledged punchersaverage power, although setting modes allows and operation in conditions demanding quality work. For example, a normal drill mode will allow you to perform accurate drilling in places of communication without risk of damaging them. Mark users and fastening type sliding, which provides convenience when replacing the rig. The power feature of the Hitachi 24 is emphasized. The puncher is supplied with non-popular lithium-ion cells, and a Ni-Cd battery. Some users criticize developers for this decision, because it is less practical. The fact is that such batteries last longer and are less active in the state of activity. The advantages of this element include toxic safety. Even the depressurization of the block will not have harmful environmental impact.
It should be noted that the model has a networkA modification that works from an ordinary outlet without requiring a recharge. This is a Hitachi DH24PH puncher, which has about the same operational capabilities, but it can only be operated with network access. But in exchange for this inconvenience, we can note a small weight of the device, which simplifies physical manipulation.
Reviews about the model DH25DAL
The apparatus continues the development of the above-describedversion, offering and serious improvements. Just in this version, the power supply is provided by a lithium-ion battery. But, as users note, the charging time for it is also considerable and is 60 minutes. But the work process was also increased in time. As a result, the operator with about the same capabilities works longer. In addition, the owners of the tool note the advanced drilling parameters. So, in concrete walls it is possible to form holes up to 26 mm. As for the metal, the Hitachi perforator allows to work with nozzles 13 mm thick. Actually, in this characteristic this model is similar to the modification DH24DV.
Reviews about the model DH36DAL
One of the most powerful versions of Japaneseperforators, which combines high productivity and comfort in carrying out work. Users point to the multifunctional attachment fixing mechanism, which allows for the replacement of drills during operation without delay. It also highlights the possibility of using several modes, including a "jackhammer". Despite the high performance, the experience of using shows the low energy values that the Hitachi puncher consumes. Reviews, of course, do not best characterize the 80-minute charge, but it suffices for a long time of operation. Moreover, the manufacturer completes the device with an additional battery pack, which doubles the operating time in conditions of complete autonomy.
How to choose a puncher?
The main criterion of choice is stillpower, as in the case of traditional network models. The strength of the target device depends on the material and structures with which it is planned to work. Next, you should pay attention to the drilling parameters with which the Hitachi perforator works in a specific modification. It's one thing if you need the formation of small niches for network wiring, and the other - if it is envisaged to create channels for laying utilities in the form of a pipeline.
Conclusion
The practice of combining several functionalopportunities in one tool does not always confirm the convenience and effectiveness of such solutions. For example, an electric screwdriver fully combines the function of a drill without impact action. Japanese developers succeeded in combining the possibilities of a perforator with conventional drilling. One of the first models of this type was the Hitachi DH26PC network puncher, the feedback about which was confirmed by the quality of the holes obtained, and high impact impact. As for the battery versions of this line, they also managed to prove the possibility of maintaining autonomy while maintaining sufficient performance. Of course, the need for additional manipulations with battery charging complicates the process, but you can not do without such a tool in the distance from the network power source.
