Labor-intensive repair work in any type of production requires the use of special equipment that performs the functions of grinding, cutting, sharpening, and polishing. At the same time, areas of cultivated areas are not always easily accessible. Angle grinders, commonly known as grinders, effectively solve a whole list of problems. Among the leading manufacturers of popular power tools, the Russian brand stands out, the most popular models of which we will consider in the review.

Several typical faults
Very often the stator breaks in Interskol grinders. it does not break, but burns. A characteristic phenomenon for such a malfunction is uncontrolled spinning of the rotor. It is very difficult to determine by eye whether the stator is really to blame for the breakdown without certain instruments. To do this you need to use a tester. If the problem is really in the stator, then it must either be replaced or rewinded.
Often the rotor also fails. It is very difficult to repair it at home on your own, so it is better to contact a service center. The causes of such a malfunction may be wear of the carbon brushes, voltage surges or jammed bearings.
Another common problem is faulty carbon brushes . The fact is that during operation they participate in constant friction against the rotor, which gradually erases them. You can replace old brushes with new ones at home on your own.
When working with the Interskol angle grinder, it is worth remembering that this is an electrical device, and appropriate safety precautions must be observed. Among other things, you need to use personal protective equipment. Required use: glasses, special headphones and gloves.

Technical parameters of angle grinders Interskol
The main consumable for an angle grinder is the disc. She uses it to polish, cut, and clean. When choosing a disk, you need to take into account that the “useful area” is four times smaller than the diameter; only the outer part is used for cutting. There are five different sizes available:
- The smallest are 115 mm. Not recommended for cutting due to the shallow cutting depth (25 mm). But the 115 mm disc is well suited for grinding work and cutting small objects. In stores you can find grinders with a disc diameter of 100 mm; their main area of application is polishing and grinding.
- Discs with a diameter of 125 mm, the most common size for household grinders. Cutting depth - 40 mm. Used for cutting any materials.
- Discs with a diameter of 150 mm are used for cutting brick, concrete and metal pipes of small diameters.
- 180 mm discs are useful when building a house or renovating an apartment.
- Professional 230 mm discs are not used in everyday life. Cutting depth - 70 mm. The larger the disc, the greater the weight of the tool.
Power ensures constant operation of the angle grinder under load. The indicators of household tools are in the range of 500–2500 W. The power does not depend on the diameter of the disk used. For household purposes, 600–900 W is enough. If long-term operation and the use of large circles are expected, then you need to take more power from 1.5 kW.
Rotational speed . This parameter is responsible for the speed of the spindle on which the disk is attached. For large disks it can be up to 9 thousand rpm. Advanced models are equipped with a manual rotation speed control. This allows for customization depending on the type of work.
One-handed and two-handed . This criterion directly affects safety and ease of use. Both options can be found on sale. One-handed models are widespread among light grinders, both domestic and professional.
Two-handed is a more powerful and weighty option, a semi-professional and professional tool. To work safely, you need to use a secure grip; you cannot do without good physical training. Some models are equipped with vibration suppression systems and rubber coating for a firm grip.
Additional features of grinders
A good grinder has many additional functions that extend its service life and make work much easier. But the more features, the higher the price. Additional functions:
- “Soft trigger” - allows you to launch the tool without jerking.
- Switching off the brushes when the current fails.
- Balancing the disc automatically allows the disc to wear evenly and reduces vibration in the hands.
- Fixing the “Start” button during long periods of work.
- Replacement of the casing without the use of additional tools.
- Additional protection from dust for the armature and stator of the angle grinder.
- Possibility of connecting a vacuum cleaner for dust removal.
Before using the tool, carefully read the instructions to avoid errors that could lead to damage. The reliability of the fastening of the grinding disc and the protective casing is checked before starting work. Using a disc that is not worn out and technically sound will help avoid its destruction and injury from fragments flying at high speed.

Advantages and disadvantages
Judging by user reviews, the Interskol grinder shows itself as a reliable and durable tool. This is what the list of main advantages looks like:
- the ability to change the position of the protective casing up to 180 degrees for a more comfortable grip;
- high power;
- a long cord, allowing in many situations not to use additional extension cords;
- low price;
- long service life;
- several handle positions.
And if there are advantages, there are usually also disadvantages. Grinders "Interskol" are also not without them, and they are worth mentioning. For example:
- models with rotation regulators quite often fail after power surges;
- the cost of components and spare parts is quite high;
- Insufficient engine ventilation can sometimes lead to engine combustion.
The durability and reliability of an angle grinder depends on how often the owner carries out preventive lubrication and replacement of components.
