Extra-long durability when drilling concrete and stone. The combination of a carbide blend developed in-house by Bosch and diamond-ground cutting edges makes the bit extremely wear-resistant. Friction on the flute from drilled material is notably reduced thanks to a 2-flute vario design with a short, variable incline providing good dust removal and wear reduction. Power Grip shank system enables 100% power transfer from machine to drill bit. This allows a direct use of power for drilling with no power loss and thus less wear. For use when drilling holes for fixings in concrete, natural and artificial stone. Cylindrical shank compatible with 3-jaw drill chucks.
