No construction site can do without cutting concrete products, and the best helper for such a task is a diamond blade for cutting concrete. The most popular power tool accessories for concrete processing are dry concrete cutting blades and wet concrete cutting blades. In this article, we will discuss what types of concrete blades exist, how to choose them and use them correctly
Types of concrete cutting blades
Depending on the design, diamond blades for concrete are divided into:
- with a solid even edge (crown),
- with a solid wavy edge (turbo),
- with an interrupted edge (segmented).
For professional concrete processing, mainly turbo concrete cutting blades and segmented diamond blades for concrete are used.
Turbo blade for concrete
Wet concrete cutting blades of the turbo type are produced on a body made of raw metal. They should not be overheated – metal expands under the influence of temperature, which can lead to cracks in the diamond layer. The turbo blade works best in short and shallow cuts, providing soft and fast operation.
Segmented diamond blade for concrete
A segmented concrete blade is one that is divided into sectors with a certain distance between them. Most segmented blades are produced on hardened steel bodies, so overheating is not a threat to such blades. In addition, the discontinuous layer of a segmented blade for concrete can freely expand and contract when overheated and cooled, which means that the appearance of cracks in such a blade is excluded.
Segmented diamond blades for concrete are perfectly suited for long and deep cuts, e.g. when cutting grooves. Cutting reinforced concrete with such concrete blades is somewhat stiffer than with turbo-type blades, however, most segmented blades handle it perfectly.
Machinability of concrete
Concrete differs in hardness and abrasiveness, which affects the choice of the right diamond blade for cutting concrete:
- High abrasiveness (class M150 and lower) – e.g. foundation blocks, curbs, roof tiles.
- Medium abrasiveness (M150–M400) – e.g. curbs and concrete products with a small metal content.
- Low abrasiveness (M400 and higher) – e.g. floor slabs, load-bearing walls, hydraulic concrete.
Concrete reinforcement also affects the choice of blade.
Choosing a concrete blade
A blade for concrete with high abrasiveness – inexpensive dry concrete cutting blades:
- Beton Pro
- Bestseller Universal
- Pro Rex
- Rapid
A blade for concrete with medium abrasiveness – optimal wet concrete cutting blades:
- XXL
- Technic Advanced
- Classic
A blade for concrete with low abrasiveness – specialized blades with a large service life reserve:
- Meteor
- Extra Max
- Super Max
Tips for cutting concrete
These simple tips will help you use diamond accessories correctly and get good service life and speed from them:
- Do not exceed the maximum speed specified by the blade manufacturer.
- Match the diameter of the diamond blade for cutting concrete to the device.
- Avoid overheating the blade.
- Always cut at the same angle, do not tilt the power tool.
- If the cutting speed drops – make a few cuts on an abrasive material (brick, asphalt, block).
- Always use protective guards and personal protective equipment – goggles, respirator, ear protection.
Additionally, after cutting is completed, it is worth leveling and preparing the concrete surface for further processing using a concrete grinding cup wheel – the perfect tool for smoothing and cleaning the surface after cutting

FAQ
Which concrete blade is better?
There is no definitive answer to this question, as there are many different types of concrete. It is best to choose a blade depending on the abrasiveness of the material and its reinforcement, as we described in the section „Choosing a concrete blade”.
Which diamond blades for concrete are the most popular?
Despite its price, one of the most popular blades is the Meteor H15. This blade easily handles concrete of any strength and reinforcement, and thanks to its high diamond layer, it has an impressive working life. The Technic Advanced blade is also very popular, as it copes perfectly with cutting concrete of medium and high abrasiveness and does so with very high efficiency.
Are diamond blades for concrete suitable for cutting reinforced concrete?
Yes, segmented diamond blades for cutting concrete handle reinforced concrete perfectly. The segmented design enables effective cutting even of materials with metal elements, maintaining precision and minimizing the risk of blade damage.
How to extend the service life of a diamond blade for concrete?
To extend the durability of a diamond blade for cutting concrete, you should:
- Avoid overheating the blade – take breaks or use wet cutting if the blade is designed for such a mode.
- Cut with even pressure and a constant angle.
- Regularly clean the blade of concrete dust and material residues.
- Use the appropriate speed recommended by the manufacturer.
Are diamond blades suitable for wet and dry cutting?
Yes, Distar produces both dry concrete cutting blades and wet concrete cutting blades. The choice depends on the type of equipment and the preferred way of working – wet cutting reduces dust and blade overheating, while dry cutting allows for fast cutting with smaller mobile devices.
