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. Friction on the spiral caused by the drilling material is significantly reduced thanks to a 2-spiral Vario design with a short, variable incline. The Bosch Power-Grip shank system ensures 100% power transfer from the machine to the drill. This allows for direct power transmission to the drilling process without loss and with less wear. The drill is ideal for dowel drilling in concrete, natural stone, and artificial stone. It 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.
