SDS-plus Pro 4 premium hammer drill, 6.0 x 215 mm. Intelligent geometry and quality design ensure long service life, precise drill holes, and maximum smoothness even under the toughest conditions. Maximum safety is provided by the optimum symmetrical head geometry with four solid carbide cutting edges, which prevents hooking during reinforcement hits. For diameters up to 10 mm, the innovative welded solid carbide head offers maximum service life and larger dust outlets for increased drilling speed. Power breakers create microcracks in the material for noticeably faster drilling progress. Low-vibration drilling is achieved with a 4-helix variospiral design. Two large-volume spirals effectively remove drill dust from the hole, while two reinforced spirals enhance safety and stability. The drill is extremely durable due to high-quality special steel, providing a very long service life for up to 50% more circular drill holes suitable for dowels. Ideal for professional use in the hardest natural stone, concrete, and masonry.
