Highly suitable for larger boreholes in concrete and natural stone. Great details such as solid carbide blades and reinforcement fibers have been developed to ensure a very long service life and maximum energy transfer. The cutting symmetry prevent catching when reinforcements are hit. Large, durable secondary bade with dynamically curved cutting edges actively support the main plate whilst enabling fast drilling progress. Based on the wear markings in the drill head, the dimensional accuracy of the dowel holes can be estimated precisely. The centring tip with a peak angle of 130° guarantees precise drilling and ensures optimum guidance during drilling. The patented core-reinforced spirals reaches the optimum between volume and breakage resistance. Vibrations are dampened, more impact energy is applied to the carbide blades and the drilling dust is removed excellently.
