BOSCH 5-piece CYL-5 concrete drill bit set Robust Line 4-8 mm 2608588165

The CYL-5 drill bit guarantees maximum durability when drilling concrete and stone. The combination of Bosch's own carbide mixture and diamond-ground cutting edges makes the drill bit extremely wear-resistant. Friction on the spiral caused by the drilling material is significantly reduced thanks to a 2-spiral Vario design with a short, variable inclination. The Bosch Power-Grip shank system ensures 100 % power transmission from the machine to the drill bit. In this way, the power transmission can be transferred directly to drilling without loss and with less wear. For dowel drilling in concrete, natural and artificial stone. The drill bit bears the PGM Masonry Drill Bit Association Board quality test mark, which guarantees conformity with strict tolerances, precise drill holes and a firm hold of the fixing material.
