The functions of a jackhammer and drill are successfully implemented in modern rotary hammers. Manufacturers produce such equipment in different versions, facilitating the workflow due to the versatility and practicality of the tool. However, the actual presence of such functionality is not always combined with ergonomics, safety and, most importantly, the performance of the equipment. The Japanese Makita 2470 FT puncher from the HR series is an exception in this respect, allowing to carry out both responsible professional tasks and delicate operations as part of home repair activities.
Model Overview
The model is a three-mode rotary hammer with a horizontal position of the power plant. The tool is characterized by providing equal torque in both reverse and forward rotation. Such a reverse stroke is rare, but the design copes with such loads. It is also worth noting that the Makita 2470 is a rotary hammer equipped with an advanced brush organization system that facilitates the replacement of carbon elements. But the main emphasis is on performance. Thanks to the long-lasting and powerful hammer, the developers increased the production resource, thereby extending the life of the tool.
The rest of the model retained the advantages that were realized in the "younger" versions of the series. True, this did not prevent the manufacturer from significantly increasing the cost at which the Makita 2470 rotary hammer is sold. Reviews, the price of 7 thousand rubles. and the characteristics of the model do not give an unambiguous answer regarding the advisability of acquiring this tool as a universal one, however, a number of new technologies and the reliability noted by many users put the development ahead of competitors in class.
Features of the structural device
The power tool is based on the engine, as well as the handle and proprietary SDS + chuck attachment system. The chuck itself is equipped with two metal protrusions for axial positioning of the drill, as well as a steel ball for holding it. On the shank of the working element there are grooves to accommodate the protrusions of the cartridge and a semicircular 2-centimeter groove designed for the ball. This device improves the reliability and accuracy of the drill tool "Makita 2470". The punch allows the ability to move the functional element in the cartridge forward and backward, which contributes to a more efficient performance of work operations.
Moreover, the design provides not only increased productivity, but also ease of use with the tool. In order to take out the drill, it is enough for the user to pull out a special ring on the chuck. Further, the ball automatically unlocks the drill of the Makita 2470 model. The hammer can be equipped with cutting parts of a cylindrical shape, which allows you to cope with the processing of wood and metal. The difference from other models in this context is that when supplying a Japanese tool, special adapters for a cylindrical drill are not required.
Specifications
Improving the performance of the model was promoted not only by the structural device, but also by the base engine power of 780 watts. As a result, the frequency of idling reaches 1100 rpm with a force of impact of 2.7 J. True, the complexity of the “filling” of the device was reflected in the dimensions. So, the length of the tool is 370 mm, the thickness is 84 mm, and the height is 214 mm. The mass of the Makita 2470 tool cannot be called modest either - the perforator weighs 2.6 kg, which in itself implies a serious load on the operator’s hands. Actually, for this reason, the designers carefully approached the development of an ergonomic handle that minimizes vibrational vibrations and facilitates the work process.
Functionality
The hammer drill operates in three modes - drilling, hammering and chiselling. To control these modes, a special switch is provided in the design, which can be used to reconfigure the tool in a matter of seconds. In the course of work, the user can count on high accuracy. The device is easy to adjust according to the drilling depth, the risks of damage to communications and materials not intended for forming holes are eliminated. It is worth noting the option of dust removal, which is equipped with a Makita 2470 puncher. Reviews emphasize that the presence of this function is especially important when working with concrete. In the process of drilling walls, dust clouds are formed, and their timely elimination allows you to keep the workplace clean.
Maintenance and Repair
First of all, the manufacturer advises to use only original and suitable components for this model, including drills. In order to increase the working life of the tool, it is also recommended to timely replace carbon brushes. As for the restoration of technical serviceability, most of the breakdowns will be eliminated only by professional repair of the Makita 2470 rotary hammer. With their own hands, the user can repair, for example, the reverse switch or repair damaged contacts. To do this, carefully remove the back cover and brush holder, and then check the quality of the connections between the starter and the switch. Contacts are restored by sanding their surfaces, after which the joints should be adjusted so that they fit tightly together.
Positive feedback about the model
Everything that relates to the internal structure, experienced builders put on the list of positive qualities of the device. High power, coupled with several modes of operation, makes the tool multifunctional and convenient to implement comprehensive repair and installation activities. Ergonomics of the tool is also noted in terms of handling it during drilling. In many respects this is the merit of the handle, which is provided with the Makita 2470 rotary hammer. The price, which averages 7 thousand rubles, is certainly rather high for such power tools, but taking into account the capabilities of this model, experts in the segment put it on the plus side.
Negative reviews
If the main advantage of the Japanese punch is its high power output, then in the first place in the list of minuses, many put unsatisfactory build quality and low working life of some parts. This does not affect the durability of the device, but these nuances nevertheless deliver certain inconveniences during operation and maintenance. For example, many owners complain about the weak design of the gearbox, which is equipped with a Makita 2470 rotary hammer. Repair of the model can also be associated with damage to the reverse contacts, replacing the cartridge and cleaning the strobes. These are the most common causes of tool failure, which are more often observed among users who regularly use a hammer drill in working with concrete.
Conclusion
This model is in many ways ahead of its competitors in class. So, while the supply of tools of this type with new ergonomic additions and functions has long been a prerequisite for development, flexible stroke settings and high engine performance of 780 watts are quite rare qualities. To this it is worth adding construction features that the Makita 2470 puncher received. Reviews, model price of 7 thousand rubles. and the quality of the workflow is more likely in favor of this unit. But it is important to consider for what purposes the instrument is purchased. To carry out irregular repair operations within the framework of private needs, it might be worth looking for a less powerful and modest punch in functionality (if only for the reason that it will cost two times cheaper). However, if we are talking about professional operation in everyday mode, then buying a Japanese model will fully justify the investment.
