An angle grinder (angle grinder) or grinder is a useful and almost indispensable tool both at home and in the field of industrial production. It can be used for grinding, cutting, polishing a wide variety of materials, from wood to fairly hard surfaces such as concrete or ceramics.
A huge number of various products are on sale today, which differ from each other not only by the manufacturer, but also by the diameters of the disks, power, number of revolutions and a number of other parameters. In order to buy a suitable model, you should carefully study all these points and take them into account during the selection. To help you in this difficult matter, we have compiled our review of the best grinders of 2020. We will start it with the key characteristics of devices that will influence the choice of model. So let’s get started.
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 interaction with the material being processed is performed. When choosing a device, it should be remembered that the useful area of u200bu200bthe disk that will be used for work is approximately a quarter of the diameter. On sale there are products with a diameter of 115, 125, 150, 180 and 230 mm.
The power of the product is able to ensure stable operation of the equipment even under fairly serious loads, and the tool will not need to 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 rating in the range of 0.6-0.9 kW. If you plan to carry out long-term work, then a variant with a capacity of at least 1.5 kW is suitable.
The number of revolutions, as a rule, is inversely proportional to the diameter of the disk – for 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 using the device depends on the number of handles: angle grinders are single-handed and two-handed. The first option is found among both household and professional models. Two-handed are always professional products, as 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.
An angle grinder may have additional functions – soft start, automatic shutdown, automatic disk balancing (reduces vibration and reduces stress 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 from users and professionals about a particular model. As a result, our review included only the most popular grinders.
