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

The functions of a jackhammer and a drill are successfully 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 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 puncher with a horizontal position of the power plant. The tool is characterized by providing equal torque for both reverse and forward rotation. This provision of the reverse stroke is rare, but the design copes with such loads. It is also worth noting that "Makita 2470" is a puncher equipped with an improved system for organizing brushes, which facilitates the replacement of coal elements. But the main emphasis is on performance. Thanks to the durable and powerful striker, the developers have increased the production resource, thus prolonging the service life of the tool.

Otherwise, the model retained the advantages that 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 device

The basis of the power tool is the engine, as well as the handle and the proprietary mounting system for the SDS + cartridge. 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 to accommodate 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.

At the same time, the design provides not only increased 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 the cylindrical drill.

Specifications

The performance of the model was enhanced not only by the construction device, but also by the base engine power of 780 W. As a result, the idle frequency reaches 1100 rpm with a shock force of 2.7 J. True, the complexity of the "filling" of the device 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, designers have carefully approached the development of an ergonomic handle that minimizes vibrations and facilitates the workflow.

Functionality

The puncher 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 advises using 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 breakages 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, then check the quality of the connections between the starter and the switch. Recover contacts by cleaning their surfaces with sandpaper, after which you should adjust the connections so that they fit tightly together.

Positive feedback about the model

All that concerns the internal device, experienced builders put on the list of positive qualities of the device. High power, coupled with several modes of operation makes the tool multi-functional and convenient in the implementation of complex repair and installation activities. The ergonomics of the tool is also noted from the point of view 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 perforator is 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 of 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 in many parameters ahead of its competitors in the 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 travel settings and high engine performance 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 acquired. 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, the purchase of the Japanese model will justify the investment.
