The Bosch EXPERT 7 Piece SDS Plus Masonry Drill Bit Set is a professional-grade collection of hammer drill bits engineered for long-life drilling through concrete and reinforced concrete. Standard two-cutter SDS Plus bits are prone to jamming on rebar and eventual breakage under sustained impact. The EXPERT SDS plus-7X addresses this directly with a Full Carbide Head — a 4-cutter tip machined from a single piece of carbide and designed to punch through steel reinforcement without snagging, stopping, or requiring a bit change. Bosch Carbide Technology integrates the hardest metal directly into the tip using a specialist welding process, creating a seamless bond between flute and carbide head. This construction is rated to last up to 3x longer than the Bosch SDS plus-3, making it a sound long-term investment for contractors drilling regularly into structural concrete. The set covers seven diameters from 5mm to 12mm, with working lengths of 50mm and 100mm to suit different fixing depths. Compatible with all SDS Plus rotary hammer drills, it is well suited to professionals installing fixings, conduit, or pipework through reinforced concrete structures.
