SDS-plus Pro 4 hammer drill / 12.0 x 600 mm. Highest drilling speed achieved by reducing friction and improving impact transmission due to the special cutting geometry on the chisel-shaped drill head. Stable and durable center point allows for pinpoint drilling. Power breakers create microcracks in the material for noticeably faster drilling progress. Enlarged reinforcement phases minimize the likelihood of snagging in reinforcement hits. 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.
