Guaranteed maximum effectiveness, robustness and speed in concrete and reinforcement. Double centring tip for easy, precise drilling, while ensuring high-level drilling progress thanks to its solid, embedded carbide head. Improved bore dust transport due to new spiral design and optimised bore dust grooves in the head. Vibration-optimised spiral. No backward-curved cutting edges prevent snagging on reinforcement. Certified by the Prüfgemeinschaft Mauerbohrer (PGM) to requirements laid down by the Deutsches Institut für Bautechnik (DIBt). Areas of application: Concrete, reinforced concrete, stone, sand-lime brick, masonry, marble, clinker bricks.
