The combination of several functions in one tool is successfully practiced by many manufacturers of power tools. The leading positions in the segment are occupied by products of the Bosch, Hitachi and Makita brands, but recently many domestic models have also been seriously competing with 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 medium performance, so it can be used in home repair work and for complex professional tasks. As a screwdriver, the machine copes with screwing standard hardware and self-tapping screws 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 bases. Such features are quite combined with the price tag of the model, which is 6.5-7 thousand rubles. In the lines of eminent competitors for this money, you can buy lower-level devices, but Interskol offers a higher tool performance. True, in terms of functionality, the Russian screwdriver is stillinferior to foreign analogues. This is evidenced by a modest range of speeds and the absence of additions common in the class that improve the ergonomics of the tool. However, the model is not deprived of its original options.
Design and 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 case, which smoothly passes into the handle. It is important to note that the Interskol DA-18ER gearbox interacts with a mechanical clutch in such a way that the user can change the torque through the spindle. This option is also mandatory for modern power tools, making it easier to work with different types of materials.
The battery deserves special attention. The manufacturer provided the user with the ability to work offline using a nickel-cadmium power supply. The fact is that manufacturers of screwdrivers usually use lithium-ion batteries, which are characterized by high capacity and compact size. In turn, the nickel-cadmium battery for the Interskol DA-18ER screwdriver is advantageous in that it takes less time to replenish the charge and can be operated at low temperatures. At the same time, its disadvantages include high toxicity and fragility.
Specifications
The type of modern batteries has practically no effect on the immediate working qualities of the tool. To a greater extent, it determines the nuances of service andoverall organization of the workflow. The main characteristics that you should pay attention to when evaluating the Interskol DA-18ER model are presented below:
- Voltage 18 V.
- Diameter of drilling wood substrates - up to 18 mm.
- Metal drilling diameter – up to 10 mm.
- Compatible screw diameter 6mm.
- Tool torque 16 Nm.
- Recessed chuck diameter - 13 mm.
- Number of speed modes - 2 (soft and hard rotation).
- Speed - 1100 rpm max.
- Weight of the device - 1.9 kg.
It has already been noted that the tool is deprived of some functions, which limits its use in some areas. In particular, this applies to the lack of percussive action and backlight. But if the punch mode is not provided in most models of this level, then the integrated flashlight has long become a standard solution even for entry-level devices.
Features of the screwdriver
Since the developers used a somewhat non-standard battery, this decision was reflected in the design features of the tool. For a massive and at the same time powerful battery, special clamps are provided to facilitate the process of changing the block. In addition, the Interskol DA-18ER battery is provided with a charge indication system that allows you to track the time intervals of the screwdriver. As for the power function, in the drilling mode, the operator can use one of 16torque steps. This feature has largely made the tool universal, in terms 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 to perform complex work. For this opportunity, the user pays with the inconvenience associated with an increase in the mass of the structure.
Package and accessories
Together with the screwdriver, the user receives a plastic storage case, charger, keyless chuck and two batteries. Against the background of other models in the segment, such a set looks more than worthy, since the same Bosch and Makita companies rarely indulge their fans by including two power supply elements and a case in the basic package. The extended addition only applies to models whose class is above average. Additional equipment and tooling are made using bit holders, direct nozzles and a dust blowing system. The manufacturer also recommends supplementing Interskol DA-18ER with hinged suspensions that facilitate the workflow, relieving the user of unnecessary power load.
Recommendations for use
Before operation, the operator must make sure that the battery level is optimal and that the attachment is sufficiently fixed. Next, you should choose the most appropriate mode of operation, in terms of force impact. For example, for operations with woodsoft torsion mode at low revs is preferable. Conversely, it is recommended to apply the maximum number of revolutions to metals. Before proceeding with twisting or drilling, the Interskol DA-18ER device should be tested by working 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 speeds. After the operation, you should put the equipment in the lock mode, remove the battery and carry out a complete cleaning of the tool. And here it is necessary to note one more nuance of the operation of the model, related to the content of the battery. Nickel-cadmium batteries are beneficial for regular use. This is due to the fact that long periods of storage of the tool reduce the capacitive potential of such batteries faster.
Positive feedback about the model
In general, the device has the same advantages as all budget counterparts. According to the owners, the tool outperforms competitors due to a balanced combination of price tag and quality. The platform of the model is focused on the versatility of operation, but this screwdriver is best manifested in solving simple household operations. For example, Interskol DA-18ER is praised for its high-quality work with self-tapping screws that need to be screwed into drywall and chipboard panels.
Negative reviews
Low cost determined and wholea number of shortcomings that are noted by users of the tool. First of all, this is a weakness of the element base. Although the plastic elements in the designs of such power tools have not bothered professional craftsmen for a long time, in household models there is often an unsatisfactory quality of such parts. Unfortunately, the “Interskol DA-18ER” filling also sins with low working resources. Reviews emphasize that in the rear, the plastic gear of the gearbox is subject to rapid wear. Such a repair with the replacement of parts can cost up to 2 thousand rubles, which is not always advisable, given the budget of the power tool itself. There are also complaints in terms of ergonomics. For example, a gear shifter loses its function over time, which forces the operator to put more effort into manipulating it each time.
Conclusion
The model cannot 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 come to terms with its shortcomings and successfully solve repair and construction tasks in various fields. By modern standards, the Interskol DA-18ER screwdriver noticeably loses to competitors in the class both in terms of functionality and in terms of reliability. If we talk about the pros, then the main among them will be the combination of cost and basic performance. Nevertheless, the design and power filling of the device is designed not only for tightening standard screws, but also for drilling metalsurfaces. On the plus side, the nickel-cadmium battery pack takes a little time to charge and provides plenty of torque.
