Design: Paddle blade with 3 wings for improved effectiveness in material removal and better force transfer when drilling due to the waved head design. The embedded carbide head withstands armouring hits. Long service life due to the extremely durable single-phase carbide alloy, very fast drilling dust removal without deflagration due to the wide twist shape, vibration optimised triple twist, DuraTec annealing process using high temperature soldering and shot-blasting technology. Certified by Prüfgemeinschaft Mauerbohrer (PGM) according to the requirements of the Deutschen Instituts für Bautechnik (DIBt). Application: Concrete of even the hardest qualities, reinforced concrete, natural stone, masonry, brick. Design: Blade profile in Y-shape for even better cutting performance and smooth running. High drilling speed, ergonomically optimised - protects joints and muscles. The computer calculated Twinmax twist profile guarantees an optimised impact energy rate. HST annealed surface for higher break-resistance in hammer drilling operation and higher strength for armouring hits. Certified by the Prüfgemeinschaft Mauerbohrer (PGM) according to the requirements of the Deutschen Instituts für Bautechnik (DIBt). Application: Concrete, stone, masonry, marble, brick.
