This Bosch EXPERT Self Cut Speed Flat Drill Bit is the 13mm diameter variant, 152mm in length — a close companion to the 12mm size and equally useful for light cable routing and installation work where a slightly wider bore is required. Rated up to 3x faster than the Bosch 2609255269 Spade Bit, the 13mm version benefits from the full EXPERT Self Cut Speed feature set. Bosch Tip Technology drives the self-feeding threaded tip into the material with minimal effort from the operator, making overhead and tight-niche drilling noticeably more manageable. The advanced wave-shaped paddle design supports rapid cutting and clean chip ejection. The 1/4″ impact-rated hex shank fits securely into impact drivers and drill drivers alike, giving professionals a versatile, high-speed solution for softwood boring applications.
