Guhring No 234 50 Piece HSS TiN-Tip Coated 1.0mm - 5.9mm By 0.1mm Drill Set

The Gühring No 234 is a professional-grade 50-piece HSS drill bit set with TiN-tip coating, spanning 1.0mm to 5.9mm in precise 0.1mm increments. Manufactured in Germany from quality German steel, this DIN 338 Type N set delivers exceptional precision and durability for demanding drilling applications across ferrous and non-ferrous materials.

The TiN coating at the drill tip significantly reduces flank and crater wear, extending tool life whilst maintaining cutting performance. Each drill features a bright flute surface that minimises friction during chip evacuation, ensuring efficient material removal. The optimised point geometry with web thinning provides precise centring and improved hole tolerance, essential for accurate metalworking.

This comprehensive set is ideally suited for professional engineers, fabricators and machinists working with steel, high alloyed steel, grey cast iron, spheroidal graphite iron, malleable cast iron, aluminium and other non-ferrous metals. The 118° point angle and right-hand cutting direction make these straight shank twist drills versatile across general engineering and precision drilling tasks. Supplied in a protective storage case for organised workshop 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
