Diamond blade for concrete: own rating of the best manufacturers
Diamond blades are produced by different manufacturers - Russian, Belarusian and European. When choosing for professional purposes, pay attention to durability, number of teeth, price and other parameters. Below is a rating of diamond blades for concrete based on customer reviews from independent sources. The main features, pros and cons of each brand are described.
Husqvarna
This is a Swedish brand that produces discs for professional gasoline-powered tools. It produces various types of cutting elements based on high-strength steel. Equipped with 15 diamond-coated teeth. Diameter 230 mm ensures ease of use. Using such equipment, you can quickly cut through high-strength materials, including brick and concrete surfaces.
Among the advantages are the following:
- reliable tool;
- very long service life;
- 15 teeth;
- there are deep grooves that allow dust to be removed and heat to be reduced;
- The set includes 2 discs;
- There are 2 holes for the pins, so the disc does not rotate on the shaft.
However, such a tool is quite expensive. There are other disadvantages:
- if there is continuous work, then you need to stop every 15 minutes to cool down;
- The device cannot be used on an angle grinder;
- water cooling will be required.
Bosch
This is a German brand of construction and household appliances. Diamond blades are produced in sets of 10 pieces. They can be used on an angle grinder with a 22 mm landing shaft.The cutting wheels have a diameter of 15 cm, are equipped with 9 teeth, and have turbocharged cutting technology. This allows heat to be quickly dissipated through the grooves. Spraying takes place in 3 layers, so these are the best diamond discs for concrete. They are reliable and durable.
The cutting speed and heat dissipation are very high. Therefore, you can work even at very high frequencies - the manufacturer claims 10,200 revolutions per minute. Other advantages include the following:
- complete set – 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.
Although such discs are more expensive than many others, they will last at least 10 years. However, it is not always possible to purchase a product individually - usually it comes in a set.
GRAFF GDD
If we talk about which diamond blade is best for cutting concrete from the budget segment, it’s worth taking a closer look at the GRAFF GDD. A company from Belarus that sells wheels whose price is lower compared to European ones.
The diameter reaches 35 cm, while the devices are equipped with 24 teeth. Each of them is coated with diamond. The cross-sectional size of the cutting part is 3.4 mm. This allows you to work with materials based on bricks, paving slabs and even curb blocks.
The discs cut at high speed and efficiently, they are quite strong and durable, and have a universal purpose. Such devices can be installed on manual cutting machines and professional machines. Judging by the reviews and technical characteristics, the main advantages include:
- the disk stands confidently and “walks” during operation;
- you can gain speed up to 5400 rpm;
- suitable for all types of cuts;
- you can work with hand tools and machine and stone cutters;
- affordable.
But there are also disadvantages. The device is quite heavy, weighing 700 g. You won’t be able to cut thin strips with it because the edge crumbles. The size of the device is 2.54 cm, which will not fit the shafts of all machines.
