Bosch 4 Piece 3 Series SDS Plus Masonry Drill Bit Set

The Bosch 4 Piece 3 Series SDS Plus Masonry Drill Bit Set is a versatile collection of SDS plus-3 drill bits designed for durable, accurate drilling in concrete and masonry. Built from high-alloy steel produced using an optimised hardening technology, these bits are engineered to withstand the rigours of heavy-duty rotary hammer work. The 4-flute dura design promotes effective dust removal during drilling, helping to prevent heat build-up and extend the working life of each bit. Indented cutting edges, formed from a Bosch-controlled carbide blend, provide additional resistance against wear — making this set well suited to demanding applications in concrete, brick, and blockwork. Each bit is compatible with all SDS plus rotary hammers, offering straightforward integration with existing site tools. As assurance of quality and precision, the bits carry the PGM Masonry Drill Bit Association Board test mark, guaranteeing compliance with tight tolerances, accurately drilled holes, and the firm hold of fixings. This makes the set a reliable choice for contractors and tradespeople who depend on consistent fixing performance.
