Guhring No 201 24 Piece HSS 1.0 -10.5mm By 0.5mm Drill Set

The Gühring No 201 is a professional 24-piece HSS drill bit set covering sizes from 1.0mm to 10.5mm in 0.5mm increments, designed for precision drilling in ferrous metals and engineered materials. Manufactured in Germany using quality German steel, this Type N DIN 338 set is optimised for demanding metalworking applications where accuracy and reliability are essential.

Each drill bit features a 118° point angle and bright steam-tempered finish, delivering consistent performance when drilling steel, cast steel, grey cast iron, spheroidal iron, and sintered powder metals. The set includes four standard tapping sizes (3.3mm, 4.2mm, 6.8mm, and 10.2mm) specifically for M4, M5, M8, and M12 threads, making it particularly valuable for maintenance engineers and metal fabricators who regularly work with threaded components.

The drill bits are supplied in a robust metal indexed case that protects the tools and provides quick size identification on site. With h8 tolerance and a machining depth capability of approximately 5xD, this set meets the exacting standards expected by professional tradespeople working with ferrous materials. The right-hand cutting direction and steam tempering process ensure extended tool life even under regular professional use.
