The SDS plus-7X drill bit offers excellent durability when drilling into reinforced concrete. Its 4-cutter full head is made from high-quality carbide, which strengthens 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 a strong bond between the head and the shank. Additionally, the 4-flute design with wide channels reduces wear on the drill bit by ensuring effective removal of drill cuttings. This drill bit is designed for use with rotary hammers in masonry, concrete, and reinforced concrete. It is compatible with SDS plus system rotary hammers. 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 bears the quality test mark from the PGM Masonry Drill Bit Association Board, which guarantees compliance with strict tolerances, precise drilling, and a secure hold of fastening materials. It is manufactured in Germany.
