RUKO HGB Set DIN 352 HSSCo 60° M5 x 0,80 Juego de machos de roscar manuales, 3 piezas

This RUKO hand tap set cuts metric coarse threads to DIN 352 with a 60° thread angle, using HSSCo cobalt high-speed steel for durability in tough materials. Unlike standard HSS sets, the cobalt alloy maintains hardness at higher temperatures, making it suitable for unalloyed and alloyed steels up to 1000 N/mm², cast iron, and non-ferrous metals.

Highlights

• Three-piece set: taper tap, second tap, and finish tap for through and blind holes.
• Precision ground threads with ISO 2 (6H) tolerance class for reliable fits.
• Square shank ensures secure grip in tap wrenches and machine holders.
• Bright finish reduces friction and improves chip flow.

In daily use

Start with the taper tap to gradually cut the thread, follow with the second tap to deepen it, and finish with the bottoming tap for full threads near the hole bottom. The right-hand cutting direction suits standard clockwise tapping. The cobalt steel resists wear when threading abrasive or high-strength steels, extending tool life in workshop or production environments.
