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