The Bosch 10 Piece HSS-R Drill Bit Set is a comprehensive metal drilling set designed for precise work in iron, steel, non-ferrous metals, grey cast iron and hard plastics. Manufactured from high speed steel (HSS), these twist drill bits offer excellent elasticity that reduces the risk of breakage during use — a key advantage when working across a range of materials and drilling conditions. The HSS-R construction is suited to both hand-held power drills and stationary drilling applications, making this set a versatile addition to any toolkit. The set includes ten bits covering diameters from 1mm to 10mm in 1mm increments, giving contractors, engineers and tradespeople a ready-to-use range for the most common drilling tasks. Compatibility across all power tool brands means there’s no need for separate sets for different machines.
