Bosch EXPERT 8 Piece Self Cut Speed Spade Drill Bit Set

About this tool

The Bosch EXPERT 8 Piece Self Cut Speed Spade Drill Bit Set is a professional-grade flat drill bit set designed for high-speed drilling through wood, ideal for electricians, plumbers, and installation contractors. At the core of the set is Bosch's Tip Technology, which uses a self-feeding threaded tip to draw each bit into the material with minimal pressure from the operator. This makes drilling in awkward positions — overhead or in confined spaces — significantly easier and less fatiguing during extended use. The wave-shaped spade paddle design accelerates cutting and improves chip clearance, contributing to drilling speeds up to 3x faster than the standard Bosch spade bit. The 1/4" impact-rated hex shank ensures compatibility with both impact drivers and drill drivers, giving tradespeople flexibility on site. Covering a range of diameters from 12mm to 32mm, this set suits the most common cable and pipe entry sizes encountered in first and second fix electrical and plumbing installations. It is equally effective across all types of softwood.
