SDS plus-7X Hammer Drill. The SDS plus-7X masonry and concrete drill offers an excellent service life when drilling into reinforced concrete. Its 4-cutter full head is made of high-quality carbide, which reinforces the head and provides exceptional impact resistance. The even distribution of drilling force ensures that there is no loss of power, thereby increasing the overall lifespan. Bosch's unique diffusion welding technology (IDS) provides strong support between the head and neck. Additionally, the 4-spiral design with wide channels reduces wear on the drill by ensuring effective chip removal. This drill is designed for use with rotary hammers in masonry, concrete, and reinforced concrete. It is compatible with rotary hammers featuring the SDS plus system. To achieve precise results, the wear indicator shows whether the hole diameter is still within tolerance for the anchors. As a mark of quality, the drill 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.
