SDS-plus Pro 4 / 26.0 x 450 mm. This drill bit offers the highest drilling speed by reducing friction and improving impact transfer, thanks to its special cutting geometry at the chisel-shaped drill head. It features a stable and durable center for precise drilling. Power breakers create micro-cracks in the material for noticeably faster drilling progress. Enlarged reinforcement phases minimize the likelihood of getting stuck on reinforcement bars. The large-volume 2-flute helix geometry with core reinforcement ensures quick removal of drill dust and maximum breakage resistance. Suitable for use in concrete, masonry, natural stone, and granite.
