Guhring No 201 41 Piece HSS 1.0 -5mm By 0.1mm Drill Set

The Guhring No 201 is a precision HSS drill bit set designed for professional metalworking applications, providing 41 pieces spanning 1.0mm to 5.0mm in precise 0.1mm increments. This comprehensive Type N DIN 338 set offers the fine size graduations that professional engineers and machinists require when drilling critical tolerance holes in ferrous metals.

Manufactured in Germany using quality German steel, these HSS drill bits feature a bright, steam-tempered surface finish and 118° point angle optimised for drilling steel, cast steel, grey cast iron, spheroidal iron, sintered powder metal, German silver and graphite. The h8 tolerance rating ensures consistent hole sizing, whilst the standard 118° geometry provides reliable chip clearance in ferrous materials.

The set arrives in a robust metal indexed case that keeps each drill bit organised and protected on site or in the workshop. With right-hand cutting direction and a machining depth of approximately 5 times diameter, these drill bits are ideally suited for precision engineering work, machinery maintenance, and fabrication tasks where exact hole sizing in steel and cast iron is essential.
