Outstanding lifespan in concrete! Laser-welded segments: the strongest connection with the steel core. Concrete is popular and found on every construction site due to its toughness and versatility. However, it can only be cut with a diamond cutting disc. We have developed the PRO Concrete to provide professionals with a cutting disc that offers a great cut and exceptional lifespan. The durability of the PRO Concrete is based on advanced design and high-quality materials. The diamond segments of the disc are laser-welded. Their low-friction design allows them to remove dust from the cut, thereby preventing wear on the side of the disc.
