Guhring No 234 19 Piece HSS TiN-Tip Coated 1.0mm -10mm By 0.5mm Drill Set

The Guhring No 234 19 Piece HSS TiN-Tip Coated Drill Set is a professional-grade twist drill bit set designed for precision drilling across a comprehensive range of diameters from 1.0mm to 10mm in 0.5mm increments. Manufactured in Germany using quality German steel, this Type N DIN 338 set delivers the performance and reliability expected by professional engineers and machinists working with ferrous and non-ferrous materials.

Each drill bit features TiN (Titanium Nitride) coating at the tip, which significantly reduces flank and crater wear to extend tool life in demanding production environments. The bright flute surface minimises friction during chip evacuation, improving material removal and reducing heat build-up when drilling steel, high alloyed steel, grey cast iron, spheroidal graphite iron, and malleable cast iron.

The 118° point angle combined with web thinning ensures precise centring and improved hole tolerances, making this set ideal for engineering workshops, fabrication shops, and maintenance applications where accuracy is critical. The straight shank design suits standard drill chucks, whilst the h8 tolerance specification guarantees consistent sizing across the complete set. All bits are supplied in a protective storage case for organised tool management.
