Bosch EXPERT 3 Piece Self Cut Speed Spade Drill Bit Set

About this tool

The Bosch EXPERT 3 Piece Self Cut Speed Spade Drill Bit Set is a professional flat drill bit set designed for fast, efficient hole drilling through timber for cable, pipe, and hardware installations. Favoured by electricians, plumbers, and installation contractors, spade bits are an everyday essential on site — and this set takes performance a step further with Bosch's Tip Technology. The self-feeding threaded tip draws the bit into wood automatically, requiring minimal pressure from the operator, which is particularly useful when working overhead or in confined spaces. The wave-shaped paddle design accelerates cutting and improves chip clearance, contributing to the notably faster drilling performance. The 1/4" hex shank is impact-rated, making these bits compatible with both impact drivers and drill drivers for added versatility on site. This three-piece set covers diameters of 20mm, 22mm, and 25mm — sizes well suited to routing cables and pipes through timber joists and stud work. All three bits share a consistent 152mm total length with a 100mm working length.
