Key advantages and benefits: Why choose a 115mm double row diamond blade?
When working with hard materials such as concrete, marble and granite, conventional grinding wheels either fail quickly or require too much time and physical effort. Our 115 mm double-row diamond wheel has been developed with maximum productivity and long service life in mind. Below are the key benefits of this premium tool:

Exceptional cutting and removal speed: The double row arrangement of diamond segments allows for significantly larger contact area and faster removal of excess material compared to standard single row discs. Your work will be done in half the time, with less effort.
High-strength synthetic diamonds: The segments use exclusively high-quality synthetic diamonds, which ensure an extremely long disc life and constant sharpness, even during long-term processing of the most abrasive and hard surfaces.
Versatile use on different materials: Forget about constantly changing tools. This diamond disc is ideal for processing and grinding concrete, marble and granite, giving you maximum flexibility and efficiency directly in the field.
Optimized for dry grinding: The special disc geometry and segment arrangement enable extremely effective self-cooling during work. This prevents the disc from overheating, extends the tool life and allows working without the use of water.
Universal compatibility: With a standard outer diameter of 115 mm and a clamping opening of 22.2 mm, this plate fits perfectly into almost all standard angle grinders (so-called flexi grinders) on the market.

Frequently Asked Questions (FAQ) about the product
1. Can I use this diamond disc for wet grinding?
This diamond disc is primarily designed, tested and optimised for dry grinding. Its advanced construction and segment arrangement allow for extremely efficient heat dissipation during operation, eliminating the need for water or other coolants to achieve superior results and long service life.
2. Which devices and brands of angle grinders is this disc suitable for?
The plate has a standard outer diameter of 115 mm and a clamping opening of 22.2 mm. This means that it is fully compatible with most standard angle grinders (so-called "flexibles") from various brands on the market that support this clamping dimension.
3. What is the main difference between a double-row and a single-row diamond blade?
The double row design of the diamond segments provides a significantly larger contact surface. This enables faster and more even material removal compared to single row discs. Working with a double row disc is more stable, accompanied by less vibration, and the end result is a noticeably flatter and smoother surface.

Instructions for using the product:
• Before use, check that the diamond disc is undamaged and that the 22.2 mm mounting hole is compatible with your angle grinder.
• Turn off the grinder and disconnect it from the power supply.
• Place the disc correctly on the spindle and secure it firmly.
• Before switching on, check that the plate is correctly centered and can rotate freely.
• Clean the surface to be sanded of any large debris and check that there are no metal objects on it.
• Turn on the sander and wait for the disc to reach operating speed, then carefully bring it closer to the surface.
• Guide the disc over the surface with even movements and moderate pressure. Avoid staying in one place for long periods of time.
• The plate is intended for processing concrete, marble and granite and is intended for dry grinding in this model.
• After finishing work, turn off the grinder and wait until the diamond disc has come to a complete stop before putting it down.

Useful tips for work:
• Dual-row design allows for efficient material removal and uniform surface grinding.
• When grinding concrete, use even pressure and keep the grinder moving.
• When dry sanding, it is recommended to use an appropriate dust extraction system, as a lot of fine dust is generated when working with concrete.
• Before starting, check that the grinder used is suitable for a 115 mm diameter disc and a 22.2 mm chuck.
• For best results, first remove larger irregularities, then work the surface gradually.
• Regularly check the condition of the diamond segments. If they are damaged or severely worn, replace the disc.

Warnings:
• CAUTION – the rotating diamond blade can cause serious injury.
• Wear safety glasses, hearing protection and appropriate respiratory protection when working. Grinding concrete can produce dust that is harmful to health.
• Use the angle grinder with a suitable protective cover and, where possible, with extraction.
• Always turn off the sander and unplug it before installing, removing or changing the disc.
• Do not use a damaged, cracked, deformed or severely worn disc.
• Do not exceed the maximum permissible speed specified by the disc manufacturer.
• This version is indicated for dry grinding; do not use water or other liquids unless specifically permitted for the specific product.
• Be careful of kickback and sudden movements of the sander when it comes into contact with uneven or hard parts of the surface.
• Do not touch the plate immediately after use, as it may be very hot due to friction.
• Store the product in a dry place, out of the reach of children and unauthorized persons.

Same summary

The 115mm double-row diamond concrete grinding disc is a practical solution for users who occasionally or regularly process concrete surfaces, whether for home renovation, construction or minor repairs. It works well for precise grinding of concrete in hard-to-reach places, where the compact size of the disc and the double-row design are an advantage for better control over the work. For larger areas or rough grinding, a smaller diameter could be a limitation, as it allows for shorter cuts and requires more passes. The product is best suited for hand or mobile tools, and when choosing it is key to check the compatibility of the diameter with your tool.
