This Bosch EXPERT Self Cut Speed Flat Drill Bit is the 38mm diameter variant, 152mm in length, well suited to larger bore applications such as 40mm push-fit fittings, heavy cable looms, and other sizeable installation routes through softwood. Delivering up to 3x the speed of the Bosch 2609255269 Spade Bit, the 38mm version maintains all the performance advantages of the EXPERT Self Cut Speed range. Bosch Tip Technology allows the self-feeding threaded tip to pull itself into the timber under minimal pressure — a significant advantage when working in cramped service voids or above ceiling level. The wave-shaped paddle supports fast, uninterrupted cutting and efficient chip removal. The 1/4″ impact-rated hex shank locks securely into both impact drivers and drill drivers, making it a reliable choice for professional installation teams.
