"Interskol DA-18ER": description and technical characteristics

The combination of several functions in one tool is successfully practiced by many manufacturers of power tools. The leading positions in the segment are the products of the brands "Bosch", "Hitachi" and "Makita", but recently, many domestic models make a serious competition to the leaders. An example of this is the device "Interskol DA 10 / 18ER", which not only received a double working function, but also a modern battery power supply system.

General information about the model

The tool has average performance, so it can be used in home repair work and in performing complex professional tasks. As a screwdriver the machine copes with screwing of typical hardware and self-cutters with a diameter of 6 mm. As a drill "Interskol DA-18ER" is able to form holes up to 10 mm, and this applies to metal substrates. Such opportunities are fully compatible with the price tag of the model, which is 6.5-7 thousand rubles. In the ranks of eminent competitors for this money you can buy junior-level devices, but "Interskol" offers a higher productivity tool. True, in terms of functionality, the Russian screwdriver is still inferior to foreign analogs. This is indicated by a modest range of speeds and the absence of common additions in the class that enhance the ergonomics of the instrument. However, the model is not deprived and its original options.

The device and the principle of operation

The basis of the screwdriver is a combination of an AC motor and a planetary-type gearbox. The filling is enclosed in a durable plastic housing, which smoothly passes into the handle. It is important to note that the Interskol DA-18ER reducer interacts with the mechanical clutch in such a way that the user can change the torque through the spindle. This option is also mandatory for modern electric tools, making it easier to work with materials of different types.

The battery deserves special attention. The manufacturer has ensured the user the possibility of working in an autonomous mode by means of a nickel-cadmium feeder. The fact is that manufacturers of screwdrivers usually use lithium-ion batteries, which differ in their large capacity and compact size. In turn, nickel-cadmium battery for the screwdriver "Interskol DA-18ER" is advantageous in that it takes less time to replenish the charge and can be operated in conditions of low temperatures. At the same time, its shortcomings include high toxicity and fragility.

Specifications

The type of modern batteries practically does not affect the direct working qualities of the tool. To a greater extent, it defines the nuances of service and, in general, the organization of the work process. The main characteristics that are worth paying attention to when evaluating the model of "Interskol DA-18ER" are presented below:

• The voltage is 18 V.
• The diameter of drilling of wood bases is up to 18 mm.
• The diameter of metal drilling is up to 10 mm.
• The diameter of the compatible screw is 6 mm.
• The torque of the tool is 16 Nm.
• The diameter of the built-in cartridge is 13 mm.
• The number of speed modes is 2 (soft and hard rotation).
• Rotational speed is a maximum of 1100 rpm.
• The weight of the device is 1.9 kg.

It has already been noted that the instrument is devoid of certain functions, which limits the possibilities of its operation in some areas. In particular, this concerns the lack of impact and illumination. But if the perforator mode is not provided in most models of this level, then an integrated flashlight has long been a standard solution even for entry-level devices.

Screwdriver Features

Since the developers used a non-standard battery in some way, this decision affected the design features of the instrument. For a massive and at the same time a powerful battery, special fixators are provided to facilitate the process of changing the unit. In addition, the battery "Interskol DA-18ER" is provided with a charge indication system that allows you to track the time intervals of the screwdriver operation. As for the power function, in the drilling mode the operator can use one of the 16 torque steps. This feature has largely made the tool universal, from the point of view of performing work operations with different building materials. But it is important to remember that the main distinguishing feature of the device is still a powerful battery designed for the production of complex works. For this opportunity, the user pays for the inconveniences associated with increasing the weight of the structure.

Equipment and accessories

Together with the screwdriver, the user receives a plastic storage case, a charger, a quick-action chuck and two batteries. Against the background of other models in the segment, this set looks more than worthy, since the same firms "Bosch" and "Makita" rarely spoil their fans with the inclusion in the basic configuration of two power elements and a case. The extended expansion extends only on models whose class is above average. Additional equipment and tooling are produced using bit holders, direct attachments and a dust extraction system. Also the manufacturer recommends to supplement "Interskol DA-18ER" with folding hangers that facilitate the work process, relieving the user of unnecessary power load.

Recommendations for use

Before operation, the operator must ensure the optimal level of battery charge and sufficient fixation of the nozzle. Next, you should choose the most acceptable mode of operation, from the point of view of force. For example, for operations with wood, a soft twisting mode at low speeds is preferable. Conversely, it is recommended to apply the maximum number of revolutions to metals. Before you start to twist or drill, the Interskol DA-18ER device should be tested in idle mode for 10-15 seconds. Then you can start work. Long and continuous drilling should be avoided. This is one of the main functional shortcomings of the device - it does not provide a system for maintaining the working function at high revs. After the operation, put the snap into the lock mode, remove the battery and perform a full cleaning of the instrument. And here it is necessary to note one more nuance of the model operation related to the battery's content. Nickel-cadmium batteries are beneficial to use in a regular work environment. This is due to the fact that long periods of storage of the tool quickly reduce the capacitive potential of such accumulators.

Positive feedback about the model

In general, the device has the same advantages as all budget analogues. As the owners say, the tool wins from competitors due to a balanced combination of price and quality. The model platform is oriented to the universality of operation, but this screwdriver is best shown in the solution of simple household operations. For example, "Interskol DA-18ER" is praised for quality work with screws, which must be screwed into the drywall and wood-chip panels.

Negative feedback

Low cost has identified a number of shortcomings, which are noted by users of the tool. First of all, this is the weakness of the element base. Although plastic elements in the construction of such power tools have long confused professional masters, in household models, unsatisfactory quality of such parts is often observed. Unfortunately, low work resources are also sinister with the filling of Interskol DA-18ER. Reviews emphasize that in the rear of the plastic gear reducer is subject to rapid wear. Such repairs with the replacement of parts can cost up to 2 thousand rubles. That is not always appropriate considering the budget of the power tool itself. There are also censures in terms of ergonomics. For example, the speed switch with time loses the clarity of the function, which causes the operator to apply more and more efforts in manipulating him each time.

Conclusion

The model can not be called new, since it has been on the market for several years. During this time, many fans of the instrument have taken shape, who have reconciled with its shortcomings and successfully solve repair and construction tasks in various fields. By modern standards, the screwdriver "Interskol DA-18ER" noticeably loses to its competitors in terms of both functionality and reliability. If we talk about the pros, the main among them will be a combination of value and basic performance. Nevertheless, the design and power filling of the device is not only designed to tighten standard screws, but also to drilling metal surfaces. The merits include a nickel-cadmium battery pack, which requires a little time for the charging process and provides sufficient torque.
