The best grinders of 2019: rating of high-quality and reliable models

Purpose and scope of angle grinders

The Bulgarian is a common name for the angle grinder (angle grinder), the production of which was first set up by a Bulgarian plant in 1954. As a universal device, angle grinder quickly became popular in many countries. Almost all types of materials can be processed with the tool:

• metal;
• alloys;
• a rock;
• brick;
• concrete;
• ceramics;
• wood.

The grinder is indispensable for construction, car repair, metalworking. On the farm, grinders are also often used for various jobs. They are easy to grind welded seams, handle wood products, descale, cut and saw profiles.

In this video, an expert will tell you how to choose the right grinder.

Varieties of grinders

Angle grinders are available for household, semi-professional and industrial applications. However, there is another classification that allows you to distribute devices by type of power supply:

1. Network. They work from a standard 220 V socket. They are distinguished by an increased number of revolutions, compactness, reliability, and low cost. You can choose discs of different diameters for the machines, as well as the necessary attachments. A significant disadvantage of electric angle grinders is dependence on a constant power source.
2. Rechargeable. Autonomous grinders powered by a lithium-ion battery. Due to the need for frequent recharging, this type is not suitable for large, long work. The tool, as a rule, has a low weight and different attachments, but the price of such models is much higher than the network ones. Also, cordless angle grinders have a limited diameter of the working discs - from 125 to 150 mm.
3. Pneumatic. This type of instrument does not have a motor. Starting is carried out by supplying air, which then acts under pressure on the blades inside the machine. Such grinders are much lighter, allow you to work for a long time without interruption, are quiet, but for full functioning they need additional equipment.
4. Gasoline. Refers to professional industrial tools. Weighty, have large dimensions, work with disks of maximum diameters. They run on gasoline, allow you to quickly cut any materials, have high power. Very noisy, expensive, clumsy.

Selection options

The best grinder is the one that meets all the basic technical parameters. To choose a tool, you need to get a good understanding of its characteristics and functions.

Disc diameter

Depending on the type of work, disks of different diameters are installed on angle grinders:

• grinding small surfaces - 115 mm;
• cutting products or profiles of small thickness - 125 mm;
• universal grinder - 150 mm;
• sawing bricks, concrete - 180 mm;
• work with all types of materials - 230 mm.

In addition to size, work attachments serve different purposes:

1. Grinding, polishing. These are discs with an emery, felt, cloth or sponge coating. They allow you to achieve the required level of roughness of the processed surface.
2. Sharpening, roughing. Abrasive discs for cleaning welded seams, sharpening cutting knives of various tools, processing concrete or stone products.
3. Removing paintwork. Twisted ball rigs for removing paint, varnish or cement from all types of surfaces.

Power and speed

The main parameters on which the overall performance of the angle grinder depends. The higher the power, the larger the disc can be installed on the device, which means that a larger area can be processed. All models have three gradations for this indicator:

• up to 900 W - suitable for plastic, glass or other low-strength materials;
• 900-1500 W - used as a universal tool;
• above 1500 W - designed for large industrial scale jobs.

The speed shows how quickly the grinder is able to work:

• up to 6000 rpm - widely used in households;
• 7000-11000 rpm - used in the manufacture of large products (doors, gates, fences);
• above 11000 rpm - indispensable for working with car bodies, where a large area must be cleaned before painting.

Tank and battery capacity

The average tank capacity of petrol grinders is 0.7–1.5 liters. If there is a spare fuel compartment, this parameter does not play a special role when buying angle grinders. If an additional canister is not provided in the model, then it is advisable to purchase an apparatus with a one and a half liter volume.

Cordless models often run on batteries with a capacity of 2 to 4 Ah. This is enough for the tool to reach speeds of up to 11,000 rpm.

For home construction work, devices with a minimum indicator are suitable, but for larger tasks it is better to take a more powerful grinder.

Number and shape of handles

According to the number of handles, grinders are of two types:

• one-handed (maximum disc diameter - 150 mm);
• two-handed (suitable for processing all types of materials).

Experts recommend purchasing two-handle models as they are more comfortable and safer. An additional ergonomically shaped handle allows you to fix the tool in the desired position, and the presence of anti-slip pads prevents the device from accidentally slipping out during operation.

Protective functions

Thanks to additional functions, working with angle grinders becomes safer, and the wear of the device itself is significantly reduced. These include:

1. Overload control. A special system automatically cuts off the power supply to the tool if the load exceeds the permissible norm.
2. Dust protection. Designed to exclude the possibility of a short circuit or breakage of the grinder due to dust or metal shavings getting inside the case.
3. Kickback protection. Prevents unintentional rotation of the grinder in case of accidental jamming of the mechanism.
4. Restart lock. If the device suddenly stops, the system does not allow it to spontaneously turn on, which reduces the possibility of injury to a minimum.
5. Inrush current limitation. A special regulator allows you to smoothly start the grinder with a gradual increase in speed.
6. Maintaining a constant speed. The mechanism compensates for the resistance that occurs when working on a hard surface, thereby preventing the disc from slowing down.
7. Disk balancing. The automatic system allows you to correctly distribute the load on the rotating part of the angle grinder to reduce the risk of uneven wear.
8. Keyless casing adjustment. Allows you to quickly change the position of the protective casing by pressing a special lever or button.
9. Speed ​​control. It is necessary to prevent fire when working with materials of low strength or surfaces with paint and varnish coating.
