Intelligent geometry with its uncompromised quality of detail ensures a long service life, precise drill holes and maximum quiet running - even on the toughest loads. Highest level of safety thanks to the optimum symmetrical head geometry with 4 full carbide cutters, which do not catch when encountering reinforcing. Up to O 10 mm: with innovative, welded full carbide head for maximum tool life and larger dust outputs for highest drill speed Power breakers cause micro tears in the material for a noticeable quicker drill progress Low-vibration drilling with 4-spiral helix. 2 large volume helixes remove the bore dust quickly and reliably from the drill hole, two reinforced spirals ensure additional safety and stability. Extremely resistant to breakage thanks to high-grade special steel Very long tool life for up to 50% more dowel-compatible circular bores For professional use in the hardest natural stones, concrete, masonry.
