The Bosch HSS Drill Bit 5.5mm delivers precision-engineered performance for demanding metal drilling applications. Constructed from high-speed steel (HSS) with precision-ground geometry, this drill bit provides reliable results across diverse metalworking tasks. The 135-degree self-centring split-point tip combines active cutting with precise positioning, eliminating wandering during initial contact. This advanced geometry achieves 40% faster drilling rates and up to 50% lower feed pressure compared to standard-ground HSS bits with chisel edges. The cylindrical shank ensures universal compatibility with three-jaw drill chucks across all brands. Suitable for iron, alloyed and non-alloyed steel, non-ferrous metals, cast iron, and hard plastic, this drill bit meets DIN 338 standards for professional and workshop applications.
