Lasting Performance in Concrete - The CYL-3 Drill Bit provides lasting performance when drilling concrete. Its stamina is a result of a highly durable carbide blend specially developed and manufactured by Bosch. The blend is adapted to meet the demands of repeated use and offers high wear resistance when working with concrete. Moreover, the effective 2-flute U-shape design of the bit provides good dust removal, reducing friction, heat development and wear, resulting in an extended lifetime. The bit delivers lasting performance when drilling holes for fixings in abrasive materials such as concrete and natural stone. It is compatible with cylindrical shank systems for all corded or cordless impact drills. As proof of quality, the drill bit bears the test mark of the PGM Masonry Drill Bit Association Board, guaranteeing compliance with tight tolerances, exact drilling and the firm hold of fixings. Cylindrical shank compatible with three-jaw drill chucks. Features and Benefits • Performan
