Choosing an angle grinder

Choosing a tool is not always easy, especially when you don’t fully understand what you want to get as a result. But with angle grinders such a situation often happens. They come in a wide variety of types: surface grinding, eccentric or tape. Moreover, relatively few know about their features. Interestingly, a universal tool simply does not exist, so there is no exact replacement for each variety. We will consider some recommendations for choice of angle grinder, which will help you choose the best option. Let’s try to see what is important to consider when buying an instrument..

Where to start the choice

At the very beginning, it is important to think about what type of model you need: professional or household? Everything is simple here: these tools are distinguished by motor resources and the time during which they can work continuously. If you purchase a professional tool, it can be used almost constantly. For their manufacture, a special material is used that can withstand high operating loads. For those who periodically plan to do the job, overpaying for professional equipment is not practical. Models for household needs allow monthly work to be performed for several tens of hours. Grinders of this type are characterized by lower weight and size, compared with their professional types. In addition, such equipment is affordable.

When buying a grinder, it is important to determine the purpose of its use. Remember that expert advice never hurts, so contact your dealer for help. Probably, it will help to see the main differences between tape, eccentric, angle and surface grinding machines. Thanks to each of the above tools, various grinding methods can be obtained, therefore, such equipment will be successful in various types of work..

Getting to the choice of grinders

Grinders are rightly classified as the most versatile varieties of grinders, because they allow polishing and grinding of surfaces. This tool is highly efficient for cutting and processing stone and metal..

An important characteristic is the size of the disks and the power of the device. In many respects, these indicators depend on the needs of the buyer. So, for cutting concrete, the best option would be to use a tool with a power of about 2 kW, the best rotation speed would be 6000 rpm. To perform grinding and polishing, there are enough models with a power of about 1 kW, in which the disk rotation speed can be lower than 6000 rpm.

The dimensions of the disk determine the maximum depth of its penetration into the material. According to this indicator, all angle grinders can be classified as medium, in them the diameter is 150-180 millimeters, small ones with 125 millimeters in diameter and large ones in which the diameter is more than 180 millimeters. The purpose of these tools may vary. Machines of medium and large sizes are especially often used in industry, and devices with small sizes find their application in everyday life..

When considering recommendations for choosing a grinder, it is important to remember that this tool does not control the speed of the disk, so it can be used to grind far from every material. Nowadays, disks for grinders are presented in a wide range, each of them corresponds to a material of a certain type. When discs are used for other purposes, they may be damaged, and there is a risk of personal injury..
