10 SDS-plus Pro 4 hammer drill bits, 5.0 x 160 mm. Highest drilling speed achieved by reducing friction and improving impact transmission due to special cutting edge geometry on the chisel-shaped drill head. Stable and durable center point ensures pinpoint drilling. Power breakers create 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 allows for rapid conveyance of drill dust and maximum fracture resistance. Suitable for use in concrete, masonry, natural stone, and granite.
