SDS-plus Pro4 Premium Hammer Drill, 25.0 x 450 mm. This drill is characterized by intelligent geometry and high-quality craftsmanship, ensuring a long lifespan, precise drill holes, and maximum smooth operation even under tough conditions. It offers maximum safety with optimal symmetrical head geometry and four solid carbide cutting edges that prevent snagging on rebar hits. For diameters up to 10 mm, it features an innovative welded carbide head for improved durability and larger dust outlets for increased drilling speed. Power Breakers create micro-cracks in the material for noticeably faster drilling progress. The low-vibration design includes a 4-helix variospiral, with two large-volume spirals that efficiently remove drill dust from the hole, while two reinforced spirals provide additional safety and stability. Made from high-quality special steel, it is extremely durable and offers a very long lifespan, allowing for up to 50% more circular drill holes for anchors. Ideal for professional use in the toughest natural stone, concrete, and masonry.
