Concrete Drill Bit Set Robust Line Silver Percussion 7pcs. D.4-12mm Working-L.40mm

The CYL-3 drill bit offers long-lasting performance when drilling concrete. Its resistance is due to a highly robust carbide mixture, specially developed and manufactured by Bosch. The mixture is designed for high durability and offers maximum wear resistance when working in concrete. In addition, the effective two-flute U-shaped design of the drill bit supports good dust removal. This reduces friction, heat build-up and wear, resulting in an extended service life. The drill bit offers high durability for anchor holes in abrasive materials such as fresh concrete and natural stone. As proof of quality, the drill bit bears the PGM Masonry Drill Bit Association Board quality test mark, which guarantees conformity with strict tolerances, precise drilling and a firm hold of the fastening materials.
