What are the criteria for choosing a good angle grinder?
The main point is the maximum diameter of the disk that can be installed on this tool, since it is with its help that the interaction with the processed material is performed. When choosing a device, remember that the usable area of the disk that will be used for operation is about a quarter of the diameter. There are products on sale whose diameter is 115, 125, 150, 180 and 230 mm.
The power of the product is able to ensure the stable operation of the equipment even at fairly serious loads, and the tool will not need rest. This indicator is in the range from 0.5 to 2.6 kW, it is not tied to the diameter of the device. For homework, it will be enough to purchase a product with a power indicator in the range of 0.6-0.9 kW. If you plan to carry out lengthy work, then the option with a minimum power of 1.5 kW is suitable.
The number of revolutions, as a rule, is inversely proportional to the diameter of the disk - in large circles it is about 7-9 thousand per minute, for compact devices this figure reaches 12 thousand revolutions. Today there are models where you can adjust the parameter.
The safety of the device depends on the number of handles: grinders are one-and two-handed. The first option is found among both household and professional models. Two-handed products are always professional products, since they weigh quite a lot, and safe work with them will require serious physical strength. It is advisable to purchase a product whose handles will be rubberized.
The grinders may have additional functions - soft start, automatic shutdown, automatic disk balancing (reduces vibration and reduces the load on the hands), fixing the start button, dust protection and so on. When developing our rating, we took into account all these points, and also took into account the price-quality ratio of the device and the feedback of users and professionals about a particular model. As a result, our review included only the most popular grinders.
