Drilling into reinforced concrete is tough work and usually leaves its mark on hammer drills. Regular two-cutter ends get stuck in reinforcement and eventually break. The EXPERT SDS plus-7X carbide head is an advanced design 4-cutter, made from a single piece of the strongest metal. It doesn't get stuck or weaken on contact.
Thanks to Bosch's Carbide Technology and carbide head, the EXPERT SDS plus-7X lasts longer than regular hammer drills. It efficiently goes through reinforcement, so there's no need to stop the drill, re-aim, or change drills.
For professional construction workers who regularly drill into concrete and reinforced concrete, for example for fixings or installations, Bosch's hammer drill EXPERT SDS plus-7X offers unparalleled performance, reliability, and longevity.
