SDS-plus Pro 4 premium hammer drill, 16.0 x 160 mm. Intelligent geometry and quality down to the last detail ensure long service life, precise drill holes, and maximum smoothness even under the toughest conditions. Maximum safety is provided by optimum symmetrical head geometry with four solid carbide cutting edges, which prevents hooking in case of reinforcement hits. For diameters up to 10 mm, the innovative welded solid carbide head offers maximum service life and larger dust outlets for the highest drilling speed. Power breakers create microcracks in the material for noticeably faster drilling progress. Low-vibration drilling is achieved through a four-helix Variospiral design. Two large-volume spirals reliably remove drill dust quickly from the drill hole, while two reinforced spirals provide additional safety and stability. Extremely unbreakable due to high-quality special steel, this drill offers a very long service life, allowing for up to 50% more circular drill holes suitable for dowels. Ideal for professional use in the hardest natural stone, concrete, and masonry.
