Bosch RobustLine CYL-5 Concrete Drill Bit Set, 3-piece, 5/6/8 mm

This three-piece carbide concrete drill bit set provides the tooling required for making fastening holes in mineral building materials. The Bosch RobustLine CYL-5 Concrete Drill Bit Set is engineered to handle the heavy impacts of hammer drilling. It is rated for direct use on concrete, natural stone, and artificial stone. Installers can rely on these components when preparing masonry for secure wall plugs or anchors. The diamond-ground cutting edges maintain structural stability under high pressure, and a specialised material mix supports consistent performance during regular use.

Each bit has a standard cylindrical shank designed to fit conventional drill chucks. The 100 mm overall length provides adequate reach for typical structural fastening tasks. To manage debris, the shaft actively channels dust away from the tip, and this continuous clearance prevents the bit from binding in deep masonry holes. A dedicated carrying case keeps the collection tightly organised between jobs, and the rigid storage solution ensures the hardware remains protected during site transit.

• 5 mm, 6 mm, and 8 mm drill bit sizes accommodate the most frequently used masonry wall plugs.
• 50 mm functional working length supports the precise creation of standard-depth anchoring holes.
• Two-flute Vario design clears dust rapidly to reduce in-hole friction and heat build-up.
• Two individual cutting edges per bit maintain consistent material removal in dense materials.
• Bosch Power Grip shank design increases power transfer and helps maintain overall hole stability.
