SDS-plus Pro 4 premium hammer drill, 7.0 x 165 mm. This drill features intelligent geometry and quality craftsmanship for long service life, precise drill holes, and maximum smoothness even under the toughest conditions. It offers maximum safety with optimum symmetrical head geometry and four solid carbide cutting edges, preventing it from hooking during reinforcement hits. For diameters up to 10 mm, the innovative welded solid carbide head ensures maximum service life and larger dust outlets for enhanced drilling speed. Power breakers create microcracks in the material for noticeably faster drilling progress. The low-vibration drilling is achieved through a four-helix variospiral design. Two large-volume spirals efficiently remove drill dust from the hole, while two reinforced spirals provide additional safety and stability. Made from high-quality special steel, this drill is extremely durable and offers a very long service life, allowing for up to 50% more circular drill holes suitable for dowels. It is designed for professional use in the hardest natural stone, concrete, and masonry.
