The SDS plus-3 drill bit offers durability when drilling into concrete. To prevent heat buildup, the 4-flute Dura-Design ensures effective chip removal and enhances longevity. It is made from high-alloy steel, manufactured with optimized hardening technology to prevent wear. For added resilience, the notched cutting edges are made from a specially controlled carbide mixture by Bosch. 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 hold of fastening materials. The drill bit is designed for use in concrete and masonry and can be used with SDS plus system rotary hammers.
