Lasts up to 5 times longer than a Bosch standard abrasive cutting disc. Diamond cutting discs are a practical accessory for craftsmen and masons who need to cut bricks and aerated concrete blocks daily. The PRO abrasive diamond cutting disc is highly effective for use on construction sites and offers a long product lifespan. The durability of the PRO abrasive is based on advanced design and high-quality materials. The diamond segments of the disc are laser-welded. With its low-friction design, it can remove dust from the cut, thus preventing wear on the side of the disc. Featuring a 25.4 mm bore, it is compatible with 20 mm bores using reducing rings.
