The CYL-3 drill bit offers long-lasting performance when drilling into concrete. Its durability comes from a highly robust carbide blend developed and manufactured specifically by Bosch. This blend is designed for high stability and provides maximum wear resistance when working with concrete. Additionally, the effective two-spiral U-shaped design of the drill bit supports good chip transport. This reduces friction, heat generation, and wear, resulting in an extended lifespan. The drill bit offers high stability for dowel drilling in abrasive materials, such as fresh concrete and natural stone. As a mark of quality, the drill bit carries the quality test mark from the PGM Masonry Drill Bit Association Board, which guarantees compliance with strict tolerances, precise drilling, and a secure hold of the fastening materials.
