Rating of 15 best grinders

Trimming and grinding machines (grinders) are widely used in production and in everyday life in order to perform operations of various complexity. This can be cutting, grinding, and polishing materials of a certain class. When choosing the right tool, they are guided by the rating of grinders.

Criteria for choosing a good grinder

When compiling a rating, the following performance characteristics are taken into account:

• Typical disk size.
• Electric power.
• Engine speed

Before buying a tool, it is also important to consider the features of its ergonomics.

The appearance of the grinder

Disc diameter

The diameter of the disc is a key indicator determining the type of work ahead.

Note! The landing size for most varieties of circles has a standard value of 22.2 mm.

When choosing this parameter, the regularity is taken into account, according to which, with an increase in the diameter of the working circle, its rotation speed increases and the developed power increases. Extreme diameters - from 115 to 230 mm.

When choosing the best option, they are guided by specific samples of grinders working with disks of the following sizes:

• Canvas 115 mm (due to its small size it is used exclusively for grinding).
• A 125 mm disc is ideal for homework (unless you plan to cut thick parts).
• The size of 150 mm is less in demand, however, is a good option when you need a model that is medium in size and power. It is used both for grinding and for cutting metals.

Disks of different sizes

The maximum size (230 mm) is in demand during repair work on large elements of facilities under construction.

Power

With increasing power of the Bulgarian electric motor, the force developed on the working axis of the tool increases, which allows you to work with more durable materials.

Important! Along with the growth of this indicator, the mass of the grinding unit increases, which is important for long-term work with it.

The industry has mastered the production of grinding machines with engines having an operating power ranging from 0.5 to 3 kW. Products with motor powers ranging in the range from 0.8 to 1.2 kW are suitable for home and garden. Samples with indicators exceeding these numbers will be more difficult to hold in their hands when using, and, in addition, they consume more electricity.

In the case when large-scale construction is planned, accompanied by the assembly of formwork and cutting of steel bars, for example, you will have to use a more powerful tool (up to 1.5 kW).

Speed

In products of the type under consideration, the maximum speed of the drive shaft (otherwise, the working number of revolutions) is in the range from 2.5 to 12 thousand rpm. The optimum operating range is from 3 to 6 thousand rpm.

Additional Information! Manufacturers of grinders this parameter is set at the design stage, linking it with the rated engine power.

Professional-class corner machines have a built-in mechanism that allows you to adjust the speed, which is very important in conditions where you often have to change the disk. This option greatly simplifies the use of the tool at high speeds (more than 10 thousand revolutions per minute).

Number of pens

Not only ease of use, but also the safety of working with it depends on the number of holders or handles on the tool body. The presence of one handle is characteristic of light samples of grinders of any class. This is because such a tool can be held with one hand.

Tool with two handles

Grinders with an extra handle belong to more massive models, handling of which requires considerable physical strength and comfortable grip. If the handles have a special rubberized coating, and are also equipped with a vibration damping mechanism, it will be much easier to work with it.

Extra features

On high-quality grinder samples, a number of functions are provided that simplify working with them and the tool durability. Some of these options are listed below:

• The so-called "soft start".
• Blocking brushes during power outages.
• Automatic disk balancing.
• Lock on.
• Possibility of electronic adjustment of rotation speed.

To increase the reliability of grinding machines, they provide protection of internal mechanisms from dust, as well as a special socket for a vacuum cleaner.
