With the Bosch SDS-MAX-7 hammer drill bit, you can drill deep into tough construction materials with complete confidence. The solid carbide 4-cutter head powers through reinforced concrete, masonry, and limestone without jamming when hitting rebar. Featuring an impressive total length of 1320 mm and a working length of 1200 mm, it allows you to create deep wall and floor penetrations for cables, conduits, and pipes in thick structures. Its engineered flutes remove drilling dust rapidly while reducing vibrations, and the 18 mm SDS-max shank ensures direct power transfer from your rotary hammer for fast, controlled progress.
