This Bosch EXPERT Self Cut Speed Flat Drill Bit is the 20mm diameter variant, 152mm in length — a popular size for electrical and plumbing installation work where a clean, consistent bore is required for conduit, grommets, or standard pipe fittings. Up to 3x faster than the Bosch 2609255269 Spade Bit, the 20mm version is built for demanding professional use. The self-feeding threaded tip, driven by Bosch Tip Technology, draws the bit into the material with minimal pressure from the operator — greatly reducing fatigue on extended drilling runs or when working in difficult overhead positions. The wave-shaped paddle design supports fast, clean cutting with efficient chip evacuation, while the 1/4" impact-rated hex shank ensures reliable, wobble-free fitting in impact drivers and drill drivers.
