However, a good building block is a challenge for your accessories. Masons working with stone today benefit from the PRO Stone, a diamond cutting disc with excellent lifespan and outstanding cutting performance. The durability of the PRO Stone is based on advanced design and high-quality materials. The diamond segments of the disc are laser-welded. Its low-friction design allows it to remove dust from the cut, thereby preventing wear on the side of the disc.
