Overview 6 species best angle grinders: how to choose what to buy, the pros and cons, features, rating

In everyday life and in work areas angle grinder acts as a universal tool that can address a wide range of tasks. Bulgarian is easy to use, it spread among domestic masters, accessible to a wide range of users.

How to choose an angle grinder

Between models, which can be found on sale, there is a difference in the specifications, which often leads to misunderstanding of the issue of choice. In addition to work at home and the need for professional use tool with different capabilities. When selecting LBM importance are the criteria below.

type tool

The most widely used electric angle grinders, and the reason lies in the availability of electricity. Such a tool is:

• net - powered by 220 V It has a relatively low price tag, a wide range of capacities. To operate such bolgarok must have power, and the operating range is limited wire length, it is often underfoot. There is a constant danger of inadvertently it to saw or grind tooling.
• accumulator - independent of the network, but the battery will still need to be periodically recharged. Excellent for use in the field. Such grinders are not characterized by high capacity, since it affects the duration of operation on a single charge. It requires a minimum set for continuous operation of the two battery with alternating charge.

Pneumatic angle grinders are mostly used in the metal industry, in areas with high humidity and where the tool is constantly exposed to tough load. energy source here stands, compressed air, and therefore such LBM connected to the pneumatic line, compressor the corresponding performance. The advantage of this equipment lies in the ability to work at high humidity and lack of overheating during intensive use.

revolutions

Spindle speed grinder used depends on the diameter tooling. The optimum value of the linear velocity range of 80 m / s. Exceeding this value leads to the destruction of equipment. Effect diameter disk on the rotation speed of:

• 115 mm - 13.3 thousand. rev / min.
• 125 mm - 12.2 thousand. rev / min.
• 150 mm - 10 thousand. rev / min.
• 180 mm - 8.5 thousand. rev / min.
• 230 mm - 6.7 thousand. rev / min.

Permissible frequency indicated on the grinder housing and in the technical specifications of each model.

Power

The value of this parameter is within 0,65-2,7 kW, the diameter depends on the display. LBM with a powerful drive capable of working with large disks. Power consumption models drive 125 mm should be at least 750 watts. Variants designed for intensive work tooling 230 mm, equipped with an engine capacity of at least 2.2 kW.

equipment

Use drivesWhose diameter exceeds the limit for a particular model grinder prohibited. Diameter tooling directly affects the cutting depth, because it is necessary to choose the angle grinders are also based on this parameter. Depending on the particular machine, the depth of cut 125 mm circle is of the order of 30-35 mm. Immerse in great depth disk fail due to gearbox size.

Additional options

The presence of additional systems increases safety and efficiency of the tool, as well as extend its life. Most often grinders are equipped with the following functionality:

• Soft start - limit the inrush current at startup LBM thereby prevents jerking tool prolongs the motor and gear life due to elimination of transient overloads.
• Anti-vibration system - self-balancing, which dampens vibrations caused by uneven rotation snap.
• Protection against accidental start - prevents unintentional start-up tool, increasing operator safety.
• Maintaining rpm - stabilizes tooling rotation speed under load, thereby increasing the efficiency of materials handling.
• speed control - allows you to manually choose the snap rotation speed, depending on the particular type of work.
• Quick-nut - is necessary to simplify the replacement of equipment, since no additional tool is required for this. All operations are performed manually.

Another useful feature for any grinder - possibility of adjusting the position of the guard without tools.
