SDS-plus Pro 4 Hammer Drill / 15.0 x 260 mm. Highest drilling speed due to reduced friction and improved impact transmission thanks to a special cutting geometry on the chisel-shaped drill head. Stable and durable center for precise drilling. Power breakers create micro-cracks in the material for noticeably faster drilling progress. Enlarged reinforcement phases reduce the likelihood of getting stuck on rebar hits. Large-volume 2-spiral helix geometry with core reinforcement for quick removal of drill dust and maximum break resistance. Suitable for use in concrete, masonry, natural stone, and granite.
