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 bit. This allows for lossless power transfer with less wear directly to the drilling process. It is suitable for dowel drilling in concrete, natural stone, and artificial stone. The drill carries the quality certification 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.
