BOSCH CYL-3 concrete drill bit 4 x 40 x 75 mm 3.3 mm 3-pack 2608597704

The CYL-3 drill bit offers long-lasting performance when drilling concrete. Its durability is the result of a highly robust carbide compound specially developed and manufactured by Bosch. The mixture is designed for high stability and offers maximum wear resistance when working in concrete. In addition, the effective two-spiral U-shape design of the drill bit supports good drill dust removal. This reduces friction, heat generation and wear, resulting in a longer service life. The drill bit offers high stability when drilling dowels 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.
