Guhring No 234 25 Piece HSS TiN-Tip Coated 1.0mm -13mm By 0.5mm Drill Set

The Guhring No 234 is a professional 25-piece HSS drill bit set with TiN-tip coating, covering sizes from 1.0mm to 13.0mm in 0.5mm increments. Manufactured in Germany using quality German steel, this DIN 338 Type N set delivers precision drilling performance across a wide range of ferrous and non-ferrous metals.

The titanium nitride coating at the tip of each drill reduces both flank and crater wear, significantly extending tool life compared to uncoated HSS drills. The bright flute surface minimises friction during chip evacuation, ensuring cleaner drilling and reducing the risk of bit binding in deeper holes. Web thinning and optimised point geometry provide precise centring and improved hole tolerances, essential for professional engineering and fabrication work.

With a 118° point angle and h8 tolerance, these straight shank twist drills are ideal for drilling steel, high alloyed steel, grey cast iron, spheroidal graphite iron, malleable cast iron, aluminium and other non-ferrous metals. The comprehensive size range in 0.5mm increments provides excellent versatility for workshop and site applications. All bits are supplied in a protective storage case for organised tool management.
