Lasts up to 4x longer than a standard multi material diamond disc - On modern construction sites you need to cut a wide variety of hard materials, and these take their toll on tools. The EXPERT MultiMaterial Disc is the ideal accessory for busy construction professionals needing to cut concrete, brick, roofing tiles and reinforced concrete - because it simply keeps doing the job for longer. The high segments on this cutting disc are made from an advanced matrix of metal and diamonds, which is designed to stay razor sharp. These segments are laser-welded onto a hard steel body; and the sides are fluted to remove dust for efficiency and longevity. This mix of optimum diamond grits and advanced design mean the Bosch EXPERT MultiMaterial Diamond Cutting Disc offers unmatched longevity. It cuts reliably for longer than even other Bosch diamond discs, ultimately providing great value. With 25.4 mm bore, fits 20 mm bores with reduction rings.
