The SDS max-9 Break Through rotary hammer drill bit is the standard choice for drilling large, deep holes in concrete. The 3-cutter tip made of fine-grain carbide is vacuum-brazed and hardened for fast results and good removal of large material pieces. The long tapered shank of the drill bit allows for breakthrough drilling, while the double U-shaped flute design offers good dust removal.

The drill bit is suitable for drilling diameters from 45 mm to 80 mm in concrete, masonry, and limestone, e.g., for securing cables and pipes in outdoor areas. It is intended for use with rotary hammer drills.
