With the Bosch SDS-MAX-7 hammer drill bit, you drill quickly and reliably through reinforced concrete, masonry, and limestone. Its solid 4-cutter carbide head prevents jamming and head breakage when you strike rebar in dense concrete. The engineered flute design clears heavy volumes of drilling dust efficiently while noticeably reducing vibrations, keeping you comfortable and in full control during tough applications. Featuring an 800 mm working length and a 40 mm diameter, it allows you to create deep pass-through holes for pipes and conduits in a single pass. The built-in wear mark clearly indicates whether the hole diameter remains within tolerance for metal anchors.
