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. CYL-3 Drill Bit provides lasting performance when drilling in concrete.
