Drills "Interskol": types, operation and repair

The Russian company "Interskol" for a relatively short period of work managed to successfully establish itself in the market of tool manufacturers. This became possible due to the combination of high quality, rich experience and professionalism of manufacturers and a favorable price of goods. To date, over 40 million units of Interskol products have been sold within the Russian Federation, and this is not to mention deliveries abroad through the online store.

For quite a long period of time, one of the most popular products of the brand has been electric drills, which differ in quality against the background of other manufacturers.

The Interskol brand offers over 15 models of drills. Their assortment includes percussion and non-percussion instruments, one- or two-speed. The capacities vary, for example, you can choose a 300 W hammerless drill, or you can vote for the DU-22 / 1200ERP2 model, the power of which reaches 1200 W.

Drills also differ in weight, for example, the mass of one is equal to 1 kilogram, and the other weighs almost 4. This is influenced by the functions provided in the tool.

If we analyze the pricing policy of the brand, then the Interskol brand offers quite an adequate price for its really high-quality products. Consider, for example, the simplest D-10 / 300ER hammerless drill. Its price is 1,490 rubles. Of course, as the set of functions grows, so does the payment for the device.

For example, the cost of a powerful two-speed impact drill DU-16 / 1050ER, suitable for work as a mixer, starts at 4,520 rubles. In short, more options require more money. However, when choosing any model, the high quality of products remains unchanged.

The company "Interskol" uses all the most modern technologies in the manufacture of its products.

• Each of the models is ready to boast a high-performance engine. In addition, the drills are equipped with brush reversing, which provides an equally high level of torque in both forward and reverse directions.
• Hammerless drills of this brand are used for making holes both in soft materials (for example, in wood) and in more durable structures (metal, steel, plastic). The most popular are impact drills, which masterfully combine the possibility of conventional drilling and drilling with axial impact (that is, drilling). These tools are capable of providing a high enough torque and are well suited for creating holes of considerable depth.

• It should be noted the high speed of the drills. This allows you to work with the tool quickly and accurately.
• The most important advantage is, of course, the reliability of the products of this brand. However, even if something happened to the instrument, you can always contact the service center. They exist in huge numbers in many cities of Russia.
• Of course, every owner of a tool from this company notes the adequate cost of products, and this is a key factor when buying, especially in combination with excellent quality.

Owners of Interskol tools still notice the disadvantages of drills.

• These include, for example, the weak built-in lighting of the working area of ​​some models of this company. Many people note the insufficient length of electrical wires, which is not always convenient when working in large spaces.
• It happens that the speeds do not immediately switch, but this, most likely, depends on the specific model and its serviceability.
• Some types of drills are equipped with large enough ventilation holes through which debris and production waste can enter.

Of course, it is important to remember that all the shortcomings are associated with the conditions in which this tool is operated, with its serviceability.

In any case, the diversity of opinions converges on one thing - the products of the Interskol brand have a large number of advantages, due to which one can completely overlook minor shortcomings.

As mentioned above, the Russian company offers a fairly wide range of drills. Your attention may be drawn to a low-speed drill with a speed of 650 rpm or tools with a high torque. You can choose the right drill from electric and pneumatic models. It is possible to buy slow-moving tools or those designed for simpler and more standard work.

Let's take a look at the Interskol product range using some products as an example.

The most popular among impact drills are almost all offered models, because each of them has its own characteristics, and the buyer chooses a product based on his own needs.

• Model DU-13 / 780ER is one of the best. Its power reaches 780 W, which is enough for large-scale construction work. Convenience lies in the presence of an additional handle, which is important when working with very hard surfaces. The diameter of a suitable drill reaches 13 millimeters, and the rotational speed is 2700 rpm. Weighing 2.2 kilograms, it is comfortable enough for long-term work.
• And here model DU-16 / 1000ER can be produced with the mark "Professional", since its power reaches 1000 W, and the drilling diameter reaches 16 millimeters. The main advantages: a metal gearbox housing, which ensures safety, an additional handle is held on an aluminum mount, the presence of a speed switch, as well as a fairly smooth speed control, which, of course, is convenient when working.

In the category "hammerless drills" the most advantageous in terms of price is the D-10 / 300ER model - its price on the official website does not reach 1.5 thousand rubles a little. It is adapted for working with small-diameter drills, suitable for working with thermoplastic materials, and its small volume and low weight affect the result of the process only from the positive side.

Its price is 5 thousand rubles, however, the quality of this drill can be considered the best. Undoubtedly, this is the most powerful engine that provides high performance of the tool for a rather long period. The metal gearbox housing made of light alloy allows it to work in rather difficult conditions. The 16mm key chuck is ideal for large tooling.

Cordless percussion drill DAU-10 / 18L2 is excellent for many types of construction work... The impact mode ensures a successful drilling process on hard surfaces, the Li-ion battery allows the drill to remain charged for a long time, the model has a high energy consumption, and there is also an LED-backlit of the working area, which is very convenient.The price, in comparison with electric tools, is quite high and reaches 6,290 rubles, but it is fully justified.

Manufacturers have foreseen and a cheaper option from the same category, for example, a cordless drill-driver DA-10 / 12M2 (2 acc.) There is also a good case with the optimal position of the tool, and a charger with a convenient charging indicator, and a backlight that is directed exactly where you need it.

In this category, probably the most popular is the D-16 / 850ER model... It has a powerful electric motor, which provides a long-lasting process of work, the metal body will help the drill to remain in proper condition for a long time.

The price starts from 4 thousand rubles, but the quality will certainly please you.

If you are thinking about buying a drill, then it is important to familiarize yourself with some of the characteristics of a truly high-quality tool.

• First of all, pay attention to the power of the device. This affects how quickly and efficiently the drill accomplishes its task. For household work, there is enough power of 500-700 watts.
• See if there is a speed adjustment function. For example, hammering or sanding requires a higher speed, and it takes about 500 rpm to tighten a screw. Therefore, adjustment is important.
• Drilling diameter. It is known that such a diameter is indicated in the instrument passport for concrete, metal and wood. At least it reaches 0.6 centimeters, then increases to 30 centimeters on multifunctional models. However, an intermediate value will be sufficient.
• Focus on the type of drill chuck. It can be quick-release or key. Undoubtedly, using the first one is much easier than the second one, since you can lose this key from the key one. But it also happens that a chuck with a quick clamp does not last long. It's up to you to decide.
• Little things like electronic speed selector, soft start or button hold are also important. With their help, you can significantly simplify the construction process and save your time.

When working with any power tool, it is necessary, first of all, to observe safety precautions.

• Check the device for any damage, make sure that no electrical wires pass through the drilling site, do not allow water to enter, fix the drill well in the chuck, check this before starting work.
• Familiarize yourself with the drill connection diagram to avoid all kinds of problems when working with the tool. Mark the future hole and, while pressing the start button evenly, push the tool in the direction of the mark.
• Release the button only when you completely pull the drill out of the hole. For large-scale work, it is convenient to use the stand, however, its reliability must be monitored.

Malfunctions can occur in both the electrical and mechanical parts of the drill. You can contact the service centers of the company "Interskol", which are in large cities of Russia. Here you can replace the failed parts, but you can handle the repair yourself.

• For example, in the event of a chuck malfunction, it is necessary to disassemble the drill body, remove the chuck itself and check the condition of the gears in the gearbox. If the teeth are destroyed or the fasteners are worn out, the gear must be replaced with a new one.

• The problem may be wear or burning of the brushes. This can be easily identified by the presence of sparking in the contact area.The brushes must be replaced with new ones, and for this, unscrew all the screws connecting the body and remove the brush holder.
• Problems often occur when pressing buttons, this is due to frequent use of the tool. In this case, you can contact the service center or look for parts in stores yourself.
