The CYL-5 drill guarantees maximum durability when drilling into concrete and stone. The combination of a Bosch proprietary carbide blend and diamond-ground cutting edges makes the drill extremely wear-resistant. The friction on the spiral caused by the drilling material is significantly reduced thanks to a 2-spiral Vario design with a short, variable inclination. The Bosch Power-Grip shank system ensures 100% power transfer from the machine to the drill bit. This way, the power transfer can be directed to the drilling process without loss and with less wear. Suitable for dowel drilling in concrete, natural stone, and artificial stone. The drill carries the quality test mark from the PGM Masonry Drill Bit Association Board, which guarantees compliance with strict tolerances, precise drill holes, and a secure hold of the fastening material.
