Hitachi battery pack: reviews

The first experience of manufacturers on the use of batteries 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 are successfully using 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 about Hitachi rotary hammers

The manufacturer relies on an organic combination of high power capacity, ease of use and energy efficiency of this product. In terms of applications, the devices are also divided into household and professional. The power of the apparatus is sufficient for carrying out 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 models of perforators 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, it is not worth counting 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 version can be easily handled. The possibility of changing the impact energy index is also emphasized. 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 to set up, which is also attributed to the pluses of this modification.

Reviews about the model DH24DV

The model can be attributed to full-fledged medium power punchers, although the setting of 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 Hitachi 24 power supply feature is also underlined. The puncher is supplied not with popular lithium-ion cells, but with 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 a harmful environmental impact.

It should be noted that the model also has a network modification, which operates from an ordinary socket, without requiring a recharge. This is the Hitachi DH24PH, which has roughly 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 device continues to develop the above version, offering serious improvements. Just in this version, the power supply is provided by a lithium-ion battery. But, as noted by users, the charging time for him 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 Japanese punchers, which combines high performance and comfort in carrying out work. Users point to the multifunctional attachment fixing mechanism, which allows the drill bits to be replaced without interruption. It also highlights the possibility of using several modes, including a "jackhammer". Despite the high performance, the experience of use 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 still power, as in the case of traditional network models. The power potential of the target device depends on the material and structures with which it is planned to work. Next, pay attention to the drilling parameters with which the Hitachi perforator operates in a particular modification. It's one thing if you need the formation of small niches for network wiring, and another - if it is envisaged to create channels for laying utilities in the form of a pipeline.

Conclusion

The practice of combining several functionalities 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, whose reviews were confirmed both by the quality of the holes produced and by the 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 to perform additional manipulations with charging the battery complicates the process, but you can not do without a power source without such an instrument.
