Guhring No 201 50 Piece HSS 5.1-10mm By 0.1mm Drill Set

The Guhring No 201 is a professional 50-piece HSS drill bit set covering 5.1mm to 10mm in precise 0.1mm increments, designed for drilling steel, cast steel, and various cast iron materials. Manufactured in Germany to DIN 338 Type N standards, this comprehensive set provides tradespeople with exceptional size coverage for precision engineering and metalworking applications.

Each drill bit features a 118° point angle and bright steam-tempered surface finish, optimised for drilling steel, high-alloyed steel, grey cast iron, spheroidal graphite iron, and malleable cast iron. The HSS construction with h8 tolerance ensures consistent accuracy across all sizes, whilst the right-hand cutting direction and approximately 5xD machining depth capability make this set suitable for a wide range of professional metalworking tasks.

The set is supplied in a metal indexed case for organised storage and quick size identification on site. Whilst optimally suited for ferrous materials, these drill bits offer limited suitability for aluminium and other non-ferrous metals, making this a versatile addition to any metal fabrication or engineering workshop.

Features and Benefits:
• 0.1mm increments provide comprehensive size coverage for precision work
• German-manufactured HSS construction ensures consistent quality and durability
• Metal indexed case keeps drill bits organised and protected
• Steam-tempered surface finish extends tool life
• DIN 338 Type N specification meets professional engineering standards
