SDS-plus Pro 4 / 22.0 x 250 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-shaped drill head. It features a stable and durable center point for precise drilling. Power breakers create microcracks in the material, resulting in noticeably faster drilling progress. Enlarged reinforcement phases minimize the likelihood of snagging during reinforcement hits. The large-volume 2-spiral helix geometry with core reinforcement ensures rapid conveyance of drill dust and maximum fracture resistance. Suitable for use in concrete, masonry, natural stone, and granite.
