The Bosch 19 Piece HSS-R Drill Bit Set is a comprehensive metal drill bit set designed for precise drilling in iron, steel, non-ferrous metals, grey cast iron, and hard plastics. Manufactured from high speed steel (HSS), these twist drill bits offer lasting performance with high elasticity to reduce the risk of breakage during use. The set covers diameters from 1 mm to 10 mm in 0.5 mm increments, making it a versatile choice for both hand-held drills and stationary drilling applications. Suitable for contractors, engineers, and tradespeople working across a range of materials, this set is compatible with all major power tool brands. The included robust metal cassette keeps all 19 bits clearly organised and protected when not in use. Bosch recommends using a coolant during drilling — such as Bosch universal cutting oil — and wearing protective eyewear at all times.
