Bosch CYL-9 MultiConstruction Drill Bit delivers stable drilling in all kinds of materials. Its centring tip provides a steady drilling start and good guidance universally. The diameter-optimised AWB brazing and hardening technology increases the robustness of the 2-cutter drill bit and reduces vibration during use. Additionally, the bit’s 4-flute dura design with a reinforced core section delivers better wear resistance and stability when drilling soft concrete. The bit is intended for practically all materials in interior fitting work, e.g. soft concrete, masonry, brick, cement asbestos, light building materials, multilayer materials, ceramics and tiles, wood, plastic, sheet metals and aluminium. It is compatible with cylindrical shank systems for all corded or cordless drills, enabling perfect results when drilling with or without impact. CYL-9 multi-construction drill bit is equipped with diamond-ground cutting edges and a special ground tip, making it perfect for multipurpose drilling. Consisting of fine-grade highly durable carbide, this bit has extra-long life and offers the best wear resistance. 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.
