"Makita 2470" (puncher): review, specifications, device and reviews

Functions of a jackhammer and a drill successfullyare realized in modern perforators. 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 a functional is not always combined with ergonomics, security and, most importantly, the productivity of technology. The Japanese puncher Makita 2470 FT from the HR series is an exception in this respect, allowing you to perform both responsible professional tasks and delicate operations within the framework of home repair activities.

General information about the model

The model is a three-mode perforatorwith the horizontal position of the power plant. The tool is characterized by providing equal torque for both reverse and forward rotation. Such provision of the reversal stroke is a rarity, but the design copes with such loads. It is also worth noting that the Makita 2470 is a puncher equipped with an improved brush system that facilitates the replacement of coal elements. But the main emphasis is on performance. Thanks to a durable and powerful striker, the developers increased the production resource, thus prolonging the life of the tool.

In other respects, the model retained its advantages,which were realized in the "junior" versions of the series. True, this did not prevent the manufacturer from appreciably increasing the price at which the Makita 2470 puncher is sold. Reviews, the price of 7 thousand rubles. and the characteristics of the model do not give an unambiguous answer regarding the appropriateness of the acquisition of this tool as a universal one, however a number of new technologies and the reliability noted by many users put development above competitors in the class.

Features of the structural unit

The basis of the power tool is the engine, andAlso the handle and firm system of fastening of cartridge SDS +. The cartridge itself is equipped with two metal protrusions for axial positioning of the drill, as well as a steel ball for its retention. On the shank of the working element are grooves for placing the protrusions of the cartridge and a semicircular 2-centimeter groove designed for the ball. Such a device increases the reliability and accuracy of the Makita 2470 tool drill. The punch allows for the possibility of moving the functional element in the chuck forward and back, which contributes to a more efficient execution of working operations.

The design provides not onlyincreased productivity, but also convenience in handling the tool. In order to remove the drill, it is sufficient for the user to pull a special ring on the chuck. Then the ball automatically unlocks the Makita 2470 drill. The perforator can be equipped with cutting parts of a cylindrical shape, which makes it possible to cope with the processing of wood and metal. The difference from other models in this context lies in the fact that the Japanese tool does not require special adapters for a cylindrical drill.

Specifications

Improving model performancecontributed not only to the construction device, but also the base engine power, which is 780 watts. As a result, the frequency of idle operation reaches 1100 rpm with the impact force of 2.7 J. True, the complexity of the "filling" of the apparatus is reflected in the dimensions. Thus, the tool length is 370 mm, the thickness is 84 mm, and the height is 214 mm. You can not call modest and the mass of the instrument "Makita 2470" - the puncher weighs 2.6 kg, which in itself implies a serious strain on the hands of the operator. Actually, for this reason, the designers have carefully approached the development of an ergonomic handle, which minimizes vibration vibrations, facilitates the working process.

Functionality

The perforator operates in three modes - drilling,impact and chiselling. To control these modes, a special switch is provided in the design, which can be reconfigured in seconds. During operation, the user can count on high accuracy. The device can be easily adjusted for the depth of drilling, eliminating the risks of damage to communications and materials not intended for hole formation. It is worth noting and the dust extraction option, which is equipped with a puncher "Makita 2470". The reviews emphasize that the presence of this function is especially important when working with concrete. In the process of drilling walls, dust clouds form, and their timely elimination allows you to keep the workplace clean.

Maintenance and repair

First of all, the manufacturer advisesUse only original and suitable components for this model, including drills. In order to increase the working life of the tool, it is also recommended that the carbon brushes be replaced in a timely manner. As for the restoration of technical serviceability, most of the failures will help to eliminate only the professional repair of the Makita 2470 perforator. With your own hands, the user can repair, for example, the reverse switch or repair damaged contacts. To do this, you need to carefully remove the back cover and the brush holder, and then check the quality of the connections between the starter and the switch. Restoring contacts is done by cleaning their surfaces with sandpaper, after which you should adjust the connections so that they fit tightly together.

Positive feedback about the model

Everything that concerns an internal device, experiencedbuilders put in the list of positive qualities of the device. High power coupled with several modes of operation makes the tool multifunctional and convenient in the implementation of complex repair and installation activities. The ergonomics of the tool is also noted in terms of handling it during drilling. In many respects it is the merit of the handle, which provides the puncher "Makita 2470". The price, which on average is 7 thousand rubles., Of course, rather big for such power tools, but given the capabilities of this model, the experts of the segment and put it in a plus.

Negative feedback

If the main advantage of the Japanese puncheris a high power feedback, then the first place in the list of minuses, many put unsatisfactory build quality and low working life of some parts. On the durability of the device it does not affect, but some disadvantages in the process of operation and maintenance, these nuances still deliver. For example, many owners complain about the weakness of the design of the reducer, which is equipped with a puncher "Makita 2470". 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 the failure of the tool, which are more often observed in users who regularly use a puncher in working with concrete.

Conclusion

This model is ahead of many parameterstheir competitors by class. So, if the supply of tools of this type with new ergonomic additions and functions has long become an indispensable condition for development, the flexible settings of the stroke and the high performance of the engine at 780 W are quite rare qualities. To this we should add the structural features that the Makita 2470 puncher got. Reviews, the price of the model is 7 thousand rubles. and the quality of the work process is more likely to be in favor of this apparatus. But it is important to consider for what purposes the instrument is purchased. To perform irregular repair operations for private needs, it may be worth looking for a less powerful and modest in the functional punch (at least for the reason that it will cost two times cheaper). However, if it is a question of professional exploitation in everyday mode, then the purchase of the Japanese model will justify the investment.
