Description
High-quality hammer drill bit with 4 cutter X-head design for improved user comfort, reduced vibration and improved hole quality. Multiple carbide tips are made from the highest quality tungsten carbide for longer life. The 4-flute spiral maximized flute entry which increases drilling speed and debris removal with a heavy-duty shank for maximum durability. Narrow land reduces friction for more efficient, faster drilling, and less bit wear. For use with SDS MAX drive hammer drills (Hilti type F, G, or Y) for anchor, fixing or clearance holes in masonry concrete, brick, or blockwork.
