Key benefits of using GROSS PRO 125mm board

Exceptional speed and efficiency: The high concentration of large synthetic diamonds (40-50 microns in size) enables extremely fast penetration through the material, significantly reducing work time.
Maximum safety with laser welding: The cutting segments are welded to the steel core using state-of-the-art laser technology. This prevents the segments from shifting even under extreme loads.
Resistance to deformation: The plate body is made of high-quality 65Mn spring steel, which maintains perfect flatness during work, absorbs vibrations and prevents the plate from twisting.
Versatility of use: Suitable for both dry and wet cutting of straight and curved lines in various building materials.

Detailed description of advanced technologies
Segmented design with 10 slots
The plate is designed with 10 special slots between the segments. These slots perform a key task during dry cutting: they allow for effective air cooling of the plate, remove dust from the cutting area and compensate for the thermal expansion of the metal. This prevents overheating and deformation of the plate body, which directly extends its service life.
Laser welded 10 mm segments
Unlike standard plates, where the segments are simply soldered, the GROSS PRO series has laser-welded segments with a height of 10 mm. This technology ensures maximum strength of the joint between the segment and the steel core, which allows safe work even at high speeds without the risk of damage.
Composition of a metallic bond with cobalt and silver
The secret to this blade's long-lasting sharpness lies in the formula of the metal bond that holds the diamond grains. It contains expensive components such as silver and cobalt, which ensure that worn diamond grains are eliminated in time, thus revealing new, sharp diamonds on the surface. This means that the blade wears evenly and the cutting is always as effective as ever.

Areas of application
This universal diamond blade is designed for cutting a wide range of hard construction materials:

Fresh and hardened concrete
Natural stone (marble, granite, sandstone)
Iron blocks and masonry materials
Brick and ceramic tiles

Due to its exceptional resistance to overloads, the board is ideal for both intensive professional use on construction sites and for home projects where uncompromising quality is required.

Frequently Asked Questions (FAQ)
1. Can I use this plate for dry cutting without water cooling?
Yes, the PRO diamond segment cutting disc 125mm is specially optimized for dry cutting. The special segment shape with 10 slots allows for effective self-cooling during rotation. Of course, it can also be used for wet cutting if desired.
2. Which tools is this cutting disc suitable for?
The disc has a standard landing diameter of 22.2 mm and an outer diameter of 125 mm, which means it is fully compatible with most standard angle grinders (so-called "flexibles") on the market.
3. What makes this board last so long compared to cheaper alternatives?
Three key factors ensure long service life: a 10 mm high cutting segment, laser welding that prevents segments from falling off, and a special metal bond with cobalt and silver that ensures even wear and continuous self-sharpening of the diamond grains.
