The Bosch PRO 5 Piece SDS Plus-5X Masonry Drill Bit Set is a professional-grade hammer drill bit set designed for drilling accurate holes in reinforced concrete. Ideal for electricians, plumbers, and HVAC installers working on infrastructure, commercial, or domestic construction projects, these SDS plus-5X bits are engineered to handle one of the most demanding drilling tasks on site. The set includes five bits across a range of diameters, covering the sizes most commonly required by tradespeople. The 4-cutter head is formed from an embedded cross of high-quality tungsten carbide, giving the bit the strength to push through rebar without jamming or breaking. This robust design contributes to a service life lasting up to 1.5x longer than a Bosch SDS plus-1 drill bit. A 4-flute design channels dust away from the cutting point throughout the drilling process, reducing buildup and maintaining consistent performance over time. The bits are compatible with all SDS plus rotary hammers.
