The Bosch EXPERT 6 Piece Self Cut Speed Spade Drill Bit Set is a professional-grade flat drill bit set designed for electricians, plumbers, and installation contractors who need to drill holes for cables, pipes, and hardware fixings in timber. At the heart of the set is Bosch Tip Technology — a self-feeding threaded tip that draws the bit into the wood without requiring significant pressure from the operator. This makes it particularly effective when drilling in awkward positions, such as overhead work or in confined spaces where controlled feed pressure is difficult to maintain. The wave-shaped paddle design accelerates chip removal and keeps the bit cutting cleanly, delivering drilling speeds up to 3x faster than the Bosch 2609255269 spade bit. The 1/4″ hex shank is impact-rated, making the bits compatible with both impact drivers and drill drivers for added versatility on site. The set includes six bits spanning a range of diameters suitable for first and second fix installation work, all at a consistent working length of 100mm.
