The CYL-3 drill bit offers long-lasting performance when drilling concrete. Its durability comes from a highly robust carbide compound specially developed and manufactured by Bosch. The compound is designed for high stability and offers maximum wear resistance when working in concrete. In addition, the effective two-spiral U-shape design of the drill bit supports good drill dust removal. This reduces friction, heat generation and wear, resulting in an extended service life. The drill offers high stability for dowel drilling in abrasive materials, such as fresh concrete and natural stone. As proof of quality, the drill bears the PGM Masonry Drill Bit Association Board quality test mark, which guarantees conformity to strict tolerances, precise drilling and a firm hold of the fastening materials.
