This Bosch EXPERT Self Cut Speed Flat Drill Bit is the 18mm diameter variant, 152mm in length, offering a versatile mid-range cutting size for a broad range of installation tasks including cable conduit and smaller pipe runs. Delivering up to 3x faster performance than the Bosch 2609255269 Spade Bit, the 18mm version excels in softwood applications typical of first-fix electrical and plumbing work. Bosch Tip Technology powers the self-feeding threaded tip, pulling the bit into the workpiece under minimal pressure and maintaining steady progress even when drilling at awkward angles or above head height. The wave-shaped spade paddle maximises cutting speed and keeps chips clearing freely, reducing clogging during extended runs. The 1/4″ impact-rated hex shank suits both impact drivers and drill drivers for maximum tool compatibility on site.
