Guhring No 234 24 Piece HSS TiN-Tip Coated 1.0mm - 10.5mm By 0.5mm Drill Set

The Gühring No 234 24-piece HSS drill bit set delivers professional-grade precision drilling with TiN-tip coating for enhanced performance and longevity. This comprehensive set covers diameters from 1.0mm to 10.5mm in 0.5mm increments, plus four standard tapping sizes (M4, M5, M8 and M12) for versatile applications across metal fabrication and engineering workshops.

Manufactured in Germany using quality German steel, these Type N DIN 338 twist drills feature high-speed steel construction with titanium nitride coating at the tip. The TiN coating significantly reduces tool flank and crater wear, extending tool life even when drilling demanding materials such as 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 tolerance, whilst the bright flute surface minimises friction during chip evacuation for cleaner, more efficient machining. Each straight shank drill bit delivers reliable performance for professional contractors and engineering workshops requiring accurate hole drilling in ferrous and non-ferrous metals. The complete set is supplied in a protective storage case for organised transportation and job site use.

Features and Benefits:
• Increased performance – the TiN-coating at the tip of the tool reduces tool flank and crater wear and longer tool life
• Improved machining of materials – the bright flute surface minimises friction during chip evacuation
• The point geometry and web thinning offer precise centring and a better hole tolerance
