EXPERT 13 Piece Self Cut Speed Spade Drill Bit Set

The Bosch EXPERT 13 Piece Self Cut Speed Spade Drill Bit Set is a professional-grade flat bit set designed for electricians, plumbers, and installation contractors drilling through-holes for cables, pipes, and fixings in timber. At the heart of each bit is Bosch's Tip Technology — a self-feeding threaded tip that draws the bit into the wood under its own action, requiring minimal pressure from the operator. This is particularly valuable when working overhead or in confined spaces where it's difficult to apply consistent force. The wave-shaped paddle design accelerates chip removal and reduces resistance during cutting, contributing to drilling speeds up to three times faster than the standard Bosch spade bit range. The set covers 13 diameters from 10mm to 32mm, providing the versatility to handle a wide range of installation tasks in one kit. Each bit features a 1/4" hex shank that is impact-rated, making the set fully compatible with both impact drivers and drill drivers — ideal for tradespeople who want to get the most from their existing tool setup.
