4-cutter full carbide head with optimized service life for reinforced concrete. The SDS plus-7X drill offers excellent durability when drilling into reinforced concrete. Its 4-cutter full head is made from high-quality carbide for exceptional impact resistance. Bosch's diffusion welding technology (IDS) provides a strong bond between the head and the shank. The 4-spiral design with wide channels reduces wear on the drill bit through effective removal of drill debris. Its continuous distribution of drilling force ensures that there is no loss of power, thereby increasing the overall lifespan. To achieve precise results, the wear indicator shows whether the hole diameter is still within tolerance for the anchors. The drill bears the quality test mark from the PGM Masonry Drill Bit Association Board, ensuring compliance with strict tolerances, precise drilling, and a secure hold of the fastening materials. This drill is designed for use with rotary hammers in masonry, concrete, and reinforced concrete. Made in Germany. Compatible with rotary hammers featuring the SDS plus system.
