10 best professional angle grinders (grinders)

A powerful grinder with a non-standard ratio of characteristics.The power of the tool is 2600 watts, which is slightly more than that of similar models from other manufacturers, and the revolutions, on the contrary, are less, only 6500. The difference is not critical and in the angle grinder it shows itself on the good side. Unless, of course, you are ready to put up with a weight of almost 7 kilograms. But the manufacturer has placed all the known options in the case. This is set to soft start by default. There is a spindle lock and a lower nut in case it breaks. The button is locked in three positions, including off. The cover rotates without a key, which is also very convenient when moving the additional handle to the other side.

Professional grinder with 2200 watts of power and 6600 rpm. A Russian brand that is not able to compete with such giants as Bosch or Makita in terms of popularity, but produces a reliable tool with a very long working life. Here they do not pay much attention to visual appeal and ergonomics. But they use only the best components and do not skimp on lubricating fluids. The owners of this grinder do not know what overheating and constant repairs are. At the same time, the tool pleases with its price, since the brand cannot afford to bully it at the expense of a big name.The main disadvantage is a lot of weight. The angle grinder is heavy and a little inconvenient to operate.

The Japanese firm Makita is famous for the reliability of its tools. Bulgarians are no exception. Now we have a professional model designed for the highest loads. Its power is 2 kilowatts at 6600 rpm. The optimal ratio that allows you to work without overheating for long hours. The duralumin case provides good heat dissipation, and many protective functions reliably protect the tool from unforeseen situations. The grinder will be protected from dust by a labyrinth seal. Know-how patented by Makita. The only module you will need to change from time to time are the carbon brushes, they are very easy to access which is also an advantage.

Before us is the best professional grinder, at least if you believe the reviews of real users on the network. There is practically no negative about the tool, and this is not surprising, because Metabo is famous for the high quality of all its products. This is a large grinder with a 230 mm disc. Rotation speed - 6600 rpm with a motor power of 2.2 kilowatts. This is the perfect combination of characteristics that allows you to load the tool to the fullest. Also here is the most thoughtful cooling system. Multiple channels and duralumin housing cool the gears and keep the lubricant from being overused.

For a professional angle grinder, one of the most important factors is cooling. The better it is thought out, the longer the tool will be able to work without stopping and fear of overheating the rotor. In this model, the cooling system is well thought out. The case is duralumin with a large amount of grease inside. The generated heat enters the radiator fins and quickly dissolves. Inside the case there is a complex scheme of labyrinths, which also serves as protection against chips and dust getting into the case. Great tool, especially for the money. In the 150 disc segment, the price is quite attractive, although not the lowest.

The Interskol company often pleases consumers with the democratic nature of its prices.Now we have a professional grinder of medium size, which is cheaper than the analogue from Bosch or Makita. Power tool 1300 watts at 8.5 thousand revolutions. The parameters are optimal for such a form factor, as is the weight of 3 kilograms. But the richness of the functionality of the model does not please. There is no soft start. Auto stop too. The casing turns over only after unscrewing the fixing nut, which is not very convenient, especially since the three-position handle. But the maintenance of the grinder is very cheap. You can replace brushes and grease on your own without contacting a service center.

Not every grinder manufacturer pampers its tools with the maximum number of options. Often you have to pay extra for their availability, but DeWALT has taken the path of maximum equipment. It already has a soft start and even an auto stop function. This is an important element of a professional tool, as it keeps the disc intact at the moment of biting. In terms of parameters, the angle grinder is closer to a large one, although the disc size is 150 millimeters. 9 thousand revolutions, and power 1400 watts.There are no restrictions on the processed materials here.

The grinder is a tool that is often subjected to high loads. If the disc is accidentally bitten, the voltage on the rotor increases many times and it is very important that the tool itself can protect itself from such moments. RESANTA can. The manufacturer has thought out the system for ensuring operability as much as possible. There are several of them, and they complement each other.In the event of a disc bite, there is an automatic stop and engine blocking. Overheating is protected by the labyrinths of channels on the gearbox and a special speed reset circuit. All this significantly improves the quality of the product and its reliability. In this, only the Japanese Makita wins against Resanta.

Not always grinders are supplied in a complete set. Often in the box there is not even a key to unscrew the disk. In this regard, BLACK+DECKER define all its competitors. Included with the grinder you get all the necessary keys. Including for shifting the casing and disassembling the casing. There are spare brushes and one more spindle. Each angle grinder user knows that it is the spindle that is the weakest part, and replacing it in the absence of this module causes a lot of problems. On top of that, you also get genuine BLACK+DECKER branded discs. And all this at a very reasonable price. As for the quality, it also pleases users.

The GWS 660 model was released by Bosch many years ago, but it is still in demand among buyers and does not leave store shelves. The secret of such popularity is the reliability of the tool, provided by the use of quality components. As experience shows, the angle grinder has been operating for many years and the maximum that it requires is the replacement of brushes. But at the time of maintenance, their disadvantages emerge. Maintainability is very low. Even replacing brushes can cause some difficulties. It is better not to think about the introduction into the body at all. However, Bosch has plenty of service centers throughout the country.
