● Particularly suitable for large drill holes in concrete and natural stone.
● The cutting symmetry prevents catching when hitting the reinforcement.
● Large, robust secondary cutting edges with dynamically curved cutting edges actively support the main insert during rapid drilling progress.
● The centering tip with a 130° tip angle ensures precise drilling and optimal guidance during drilling.
● The patented, core-reinforced spiral achieves the optimum balance between volume and fracture resistance.
● Vibrations are dampened, more impact energy is applied to the carbide cutting edges, and drilling dust is excellently removed.
● Even breaks through reinforcement.
● The reinforcement chamfers ensure optimal drilling behavior and prevent catching on reinforcement.
● The four spiral lands operate evenly, reducing spiral wear.
● The centering point facilitates positioning and precise drilling.
● The symmetry of the solid carbide cutting edges prevents catching on reinforcement.
● 4-spiral helix geometry for smoother operation and low-vibration drilling.
● Up to 50% longer service life.
