7-piece CYL-3 Robust Line drill bit set for drilling in concrete. CYL-3 drill bits offer long-lasting performance when drilling. They are characterized by high stability for dowel drilling in concrete and natural stones. The high wear resistance results from a robust carbide mixture developed and manufactured by Bosch. The effective, double-spiral U-shape design ensures good chip removal, reduced friction, and extended lifespan.

Diameter: 4 / 5 / 6 / 6 / 8 / 10 / 12 mm, working length: 4 / 5 / 6 / 6 / 8 / 8 / 9 cm. The CYL-3 drill bit provides 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 fastening materials. It is compatible with cylindrical shank systems for corded or cordless hammer drills.
