The BlueSpot 3 Piece SDS Plus Drill Bit Set is a masonry drilling set designed for use with SDS Plus rotary hammer drills on concrete, masonry, lightweight block, and stone. Each bit in the set features a carbide tip for reliable penetration into hard materials, paired with a sandblasted finish that helps with chip clearance during drilling. The set includes three large-diameter bits — 12mm, 16mm, and 24mm — all at 450mm in length, making them well suited to deep drilling tasks such as installing fixings, pipework, or cable runs through thick masonry walls. This set is a practical choice for builders, groundworkers, and contractors who need a range of larger SDS Plus bits for heavy-duty masonry work. The varied diameters cover common fixing and core requirements, reducing the need for multiple individual purchases.
