SDS-lus Pro 4 hammer drill / 10.0 x 600 mm. Highest drilling speed by reducing friction and improved impact transmission due to special cutting geometry on the chisel-shaped drill head. Stable and durable center point for pinpoint drilling. Power breakers cause microcracks in the material for noticeably faster drilling progress. Enlarged reinforcement phases reduce the likelihood of snagging in reinforcement hits. Large-volume 2-spiral helix geometry with core reinforcement for rapid conveyance of drill dust and maximum fracture resistance. For use in concrete, masonry, natural stone, and granite.
