Drilling into reinforced concrete is a tough job and usually leaves its mark on the hammer drills. Regular two-cutter ends get stuck in the reinforcement and eventually break. The EXPERT SDS plus-7X carbide head is an advanced 4-cutter design 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 the carbide tip, the EXPERT SDS plus-7X lasts longer than regular hammer drills. It effectively goes through the reinforcement, so there's no need to stop drilling, 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.
