SDS plus-7X Hammer Drill Bit. The SDS plus-7X masonry and concrete drill bit offers an excellent service life when drilling into reinforced concrete. Its 4-cutter full head is made from high-quality carbide, which reinforces the head and provides exceptional impact resistance. The consistent distribution of drilling power ensures that there is no loss of performance, thereby increasing the overall lifespan. Bosch's unique diffusion welding technology (IDS) provides strong adhesion between the head and the neck. Additionally, the 4-spiral design with wide channels reduces wear on the drill bit by ensuring effective removal of drill dust. This drill bit is designed for use with hammer drills in masonry, concrete, and reinforced concrete. It is compatible with hammer drills featuring the SDS plus system. To achieve precise results, the wear indicator shows whether the hole diameter is still within the tolerance for the anchors. As a mark of quality, the drill bit carries the quality test mark from the PGM Masonry Drill Bit Association Board, which guarantees compliance with strict tolerances, precise drilling, and a secure grip in the drill chucks. It is manufactured in Germany.
