Diamond grinding wheel HERMAN GD-40 Precisa For fine grinding of concrete

This diamond turbo grinding cup wheel is designed for fine surface grinding on hard construction materials such as cured concrete, brick, and stone. It features turbine-shaped 6 mm diamond segments, arranged to maximize contact area while supporting smooth, controlled grinding. As a result, the tool delivers both precision and durability during long grinding sessions.

Each segment uses high-concentration synthetic diamond grains, bonded with a soft matrix. This ensures fast material removal while minimizing vibration. The segment layout includes deep cooling grooves and wide ventilation holes in the disc body, which support continuous airflow. Consequently, heat buildup is reduced, and grinding dust is expelled more efficiently.

To guarantee long-term safety and stability, the segments are pressed and sintered at high pressure, securing them tightly to the core. This reliable bond allows for smooth, uninterrupted performance under heavy use.

For best results, especially indoors, connect this wheel to a dust extraction system such as the TQ-10, paired with an industrial vacuum. This minimizes dust dispersion, increases visibility, and ensures a safer working environment.
