Diamond grinding wheel HERMAN GD-30 Hooligan For rough grinding of concrete

This diamond grinding cup wheel for rough concrete delivers rapid material removal on hard substrates. It features 6 mm thick diamond segments, arranged both transversely and circumferentially, which improves contact area and grinding speed. As a result, the disc ensures efficient surface preparation even on uneven concrete or masonry.

The segments are made with synthetic diamond grains held in a soft bond matrix, providing both cutting power and durability. In addition, this structure allows for better control during aggressive grinding.

Each segment is securely attached to the steel core using high-pressure sintering technology. This method strengthens the bond and eliminates vibration or detachment during operation. Moreover, the disc includes oversized ventilation holes, which improve airflow and assist in cooling. This also helps evacuate dust from the grinding zone, keeping your view clear and the tool efficient.

For indoor jobs, we highly recommend connecting the wheel to a TQ-10 extraction system paired with an industrial vacuum. This setup not only increases safety, but also improves productivity by reducing airborne dust and extending tool life.
