The CYL-5 drill bit ensures exceptional durability when drilling in concrete and stone. The combination of the carbide blend, developed at Bosch facilities, and the diamond-ground cutting edges make the drill bit extremely wear-resistant. Friction in the flute, due to the dust from the material being drilled, is significantly reduced thanks to the vario double flute design, which features a small, variable pitch that offers good dust removal and reduced wear. The Power Grip shank system enables 100% power transmission from the tool to the drill bit. 

This allows for immediate use of power for drilling, without power loss and, consequently, with less wear. For drilling holes for fixings in concrete, natural and artificial stone. It is compatible with cylindrical shank systems for all impact drills with or without a cord.
