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 include concrete, reinforced concrete, stone, sand-lime brick, masonry, marble, and clinker bricks.
