large carbide cutting edge with reinforcement chamfers at each end of the cutting edge. lower vibration and better drilling performance in reinforcing bars for longer service life. specially developed, robust head geometry with optimal 4 x 90° cutting symmetry. no blocking of the drill when hitting reinforcement steel. centering point with 130° angle. fast, precise drilling and optimal guidance during drilling. large, robust secondary cutting edge with dynamic cutting edge. supports the main cutting edge for faster drilling progress. shorter winding. for faster drill dust transport from the head to the spiral, less wear and heat build-up at the drill head. innovative, optimized carbide main cutting edge. wear indicator on both sides of the carbide element. guaranteed precise drilling and dimensionally accurate drill holes throughout the entire operating life. patented, core-reinforced spiral (KVS). low-vibration drilling performance and extreme breakage resistance. impact energy is transferred directly to the drill tip. large-volume spiral. faster drill dust removal for faster drilling progress and long service life. low-vibration drilling for high user comfort. special surface treatment for increased resistance. PGM tested. guaranteed perfectly fitting dowel holes throughout the entire operating life
