Guhring No 17 25 Piece HSS TiN Coated 1.0 -13.0mm By 0.5mm Drill Set

The Guhring No 17 is a professional 25-piece HSS drill bit set with titanium nitride coating, spanning 1.0mm to 13.0mm in 0.5mm increments. This German-engineered drill set delivers reliable performance for tradespeople working with ferrous metals and cast iron materials. Manufactured in Germany from quality German steel, these Type N DIN 338 straight shank twist drills feature a 118° point angle optimised for drilling steel, high alloyed steel, grey cast iron, spheroidal graphite iron and malleable cast iron. The TiN coating enhances wear resistance and reduces friction during drilling operations, extending tool life in demanding workshop and site environments. Each drill bit in the set maintains h8 tolerance standards and offers a machining depth of approximately 5 times the diameter. The right-hand cutting direction and ~5xD depth capacity make this set suitable for general metalworking applications, engineering workshops and maintenance tasks. While optimised for ferrous materials,
