SDS-plus Pro 4 / 18.0 x 200 mm. This drill bit offers the highest drilling speed by reducing friction and improving impact transmission, thanks to its special cutting edge geometry on the chisel-like drill head. It features a stable and durable center for precise drilling. Power breakers create micro-cracks in the material, resulting in a noticeably faster drilling progress. Enlarged reinforcement phases minimize the likelihood of getting stuck on reinforcement bars. The large-volume 2-spiral helix geometry with core reinforcement ensures quick removal of drill dust and maximum break resistance. Suitable for use in concrete, masonry, natural stone, and granite.
