Husqvarna
This is a Swedish brand that produces discs for professional tools on a gasoline engine. It produces various types of cutting elements based on high-strength steel. Equipped with 15 teeth with diamond coating. The diameter of 230 mm ensures comfortable operation. With the help of such equipment, you can quickly cut through materials of high strength, including brick and concrete surfaces.
Among the advantages are the following points:
- reliable tool;
- very long service life;
- 15 teeth;
- there are grooves of great depth, allowing to remove dust and reduce heat;
- 2 disks are included in the set;
- there are 2 holes for the pins, so the disk does not rotate on the shaft.
At the same time, such a tool is quite expensive. There are other downsides:
- if there is continuous work, then every 15 minutes you need to stop to cool;
- the device cannot be used on a grinder;
- water cooling is required.
Bosch
This is a German brand of construction and household appliances. Diamond blades are produced in a set of 10 pcs. They can be used on a grinder with a 22 mm landing shaft. The cutting wheels have a diameter of 15 cm, are equipped with 9 teeth, and have a turbocharged cutting technology. This allows you to quickly remove heat through the grooves. The spraying goes in 3 layers, so these are the best diamond blades for concrete. They are distinguished by reliability and durability.
The cutting speed and heat dissipation is very high. Therefore, you can work even at very high frequencies - the manufacturer claims 10200 revolutions per 1 minute. Other advantages include the following:
- equipment - 10 discs at once;
- no need to use a water cooling system;
- universal purpose - suitable for any type of work;
- thickness 2 mm - increased resistance to fracture.

The discs cut at high speed and efficiently, they are quite strong and durable, the purpose is universal. Such devices can be put on manual cutting and professional machines. Judging by the reviews and technical specifications, the main advantages include:
- the disk stands confidently, “walks” during operation;
- you can gain speed up to 5400 rpm;
- suitable for all types of cuts;
- you can work with hand tools and on machine tools and stone cutters;
