Coarse diamond grinding disc 125mm - double row: Top performance for the most demanding projects
Looking for an extremely effective and durable tool for fast removal of hard construction materials? The 125mm Coarse Diamond Grinding Wheel - Double Row (SKU: 72955) is a professional tool designed for intensive grinding and roughing of the hardest surfaces. Whether you are a professional builder, ceramicist or a passionate DIYer, this diamond grinding wheel delivers fast, precise and long-lasting results without unnecessary effort.
Thanks to its robust design and optimized diamond segment arrangement, the disc is ideal for removing thick layers of concrete, leveling surfaces after formwork removal and preparing substrates for further processing. Invest in a tool that will save you time and energy on every project.
Why choose a 125mm double-row diamond grinding wheel?
The key to success in grinding hard materials lies in the quality of the grinding media. This diamond disc features a two-row segment design, which means twice the efficiency compared to single-row discs. The two rows of diamond segments ensure more stable tool guidance, a larger contact surface and significantly faster material removal.
Designed for dry or wet processing of a wide range of building materials, the board easily creates a perfectly prepared, rough surface, which is essential for strong adhesion of new layers of plaster, leveling compounds, adhesives or waterproofing.
Key advantages and benefits of using

Exceptional removal rate: The dual-row arrangement of 14 diamond segments enables aggressive and fast grinding of even the hardest surfaces.
Long service life: High-quality diamond grains and a resistant bond ensure minimal wear even during long-term use and heavy loads.
Versatile use: Ideal tool for concrete, natural stone, marble, granite and brick.
Perfect surface preparation: By creating a rough texture, it provides excellent adhesion for the subsequent application of plaster, putty or tile adhesive.
Precision leveling: An excellent choice for removing seams, irregularities and sagging that occur after formwork removal.

Tips for safe and efficient work
To achieve the best results and extend the life of your new diamond blade, please follow these recommendations:
1. Control the pressure: Do not apply too much pressure to the surface during operation. Let the diamond segments do the work themselves. Excessive pressure can cause the disc to overheat and overload the power tool.
2. Adequate tool power: Use angle grinders with sufficient capacity (power) that can maintain stable rotations under load.
3. Gradual removal: If you need to remove a thicker layer of material, do the job in several successive passes instead of in a single deep cut.
4. Use protective equipment: Always wear safety glasses, a dust mask (recommended with a dust extractor) and protective gloves when grinding concrete and stone.

Frequently Asked Questions (FAQ)
1. What materials is this diamond blade best suited for?
The disc is specially designed for roughing and removing hard building materials such as concrete (including reinforced concrete), natural stone, marble, granite and brick. It is also excellent for removing adhesive and coating residues.
2. Can the plate be used for dry sanding?
Yes, the disc is suitable for dry sanding. The embossed base and double-row design allow for effective cooling and dust removal. We strongly recommend using a dust extraction system when dry sanding.
3. How does a two-row design affect work compared to a single-row design?
The dual-row design (14 segments) offers a significantly larger grinding surface, which means faster material removal and smoother tool guidance. It is less prone to vibration, which reduces user fatigue and ensures a more consistent grinding result.

• Turn on the grinder and start grinding or processing the material.
• After finishing work, turn off the grinder and carefully remove the diamond disc.

Useful tips for work:
• Before using the diamond disc, check that it is clean and undamaged, as a damaged diamond disc can cause problems when grinding or processing the material.
• When using the grinder, be careful not to apply too much pressure, as this may cause damage to the material or the diamond disc.
• To achieve the best results when grinding or machining, use a diamond disc in combination with other tools for working with materials.

Warnings:
• Always wear safety glasses or a face shield when working.
• When grinding mineral materials, use appropriate respiratory protection and, if necessary, hearing protection.
• Always turn off the sander and unplug it before installing, removing, or inspecting the disc.
• Do not use a cracked, deformed, chipped or otherwise damaged disc.
• Do not exceed the maximum permitted rotation speed of the disc.
• Only use the disc on a grinder for which it is suitable in terms of dimensions and mounting method.
• Do not remove the protective cover of the angle grinder and do not use it without proper protection.
• Keep hands and other body parts away from the rotating disc.
• Do not use excessive force or strike the plate.
• Prevent the turntable from coming into contact with flammable materials.
• A large amount of dust may be generated during work; avoid inhalation and ensure adequate extraction.
• If strong vibrations, unusual sounds, damaged segments or other abnormalities occur, stop work immediately.
• After switching off, do not touch the hob until it has completely stopped and cooled down.

Same summary

The 125 mm diameter coarse diamond grinding disc with a two-row design is a suitable choice for users who need efficient material removal when grinding concrete, stone or other hard surfaces. The two-row structure allows for faster and more even grinding, which is especially useful for larger surfaces or more demanding renovation work. Before purchasing, it is recommended to check the compatibility of the disc diameter with your existing tool, as incorrect selection may reduce work efficiency or affect safety. The disc is less suitable for very fine processing or for grinding softer materials where higher precision is required.

Answers to frequently asked questions

For which materials is this diamond grinding wheel best suited?

The disc is specifically designed for rough grinding of concrete, various types of stone and harder surfaces where rapid material removal is important. It is not recommended for fine finishing or softer materials such as wood.

Is the disc compatible with universal angle grinders?

The 125 mm diameter fits most standard angle grinders, but it is imperative to check the recommended size and compatibility of the disc with your own tool before use.

What is the advantage of the two-row panel design?

The dual-row design allows for more efficient and faster sanding of larger areas and helps with better control of material removal in less time.

Does the lifespan of a panel depend on how it is used?

Yes, the durability of the board depends greatly on the appropriate choice of material, sanding technique and proper storage after use.

Can I use one plate for several different materials?

For best safety and efficiency, it is recommended that you use the disc only for the material it is intended for. Using the same disc for several very different materials can lead to faster wear and poorer results.
