The CYL-3 drill bit offers long-lasting performance when drilling into concrete. Its durability comes from a highly robust carbide blend specially developed and manufactured 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, reducing 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. It is compatible with cylindrical shank systems for both corded and cordless hammer drills. As a mark of quality, the drill bit carries the quality test mark from the PGM Masonry Drill Bit Association Board, ensuring compliance with strict tolerances, precise drilling, and a secure hold of fastening materials.
