RUKO HGB-DIN352-HSS-M20x2,5mm conjunto de machos manuais, métrico grosso, 3 peças, HSS, DIN 352

The RUKO HGB-DIN352-HSS-M20x2.5mm is a 3-piece hand tap set for cutting metric coarse threads with a 2.5 mm pitch. Unlike single taps, this set includes rougher, second, and finisher taps, enabling progressive cutting for cleaner, more accurate threads in manual applications.

Highlights

• Complete set: rougher, second, and finisher taps for sequential thread cutting
• Precision ground from high-speed steel (HSS) for durability and clean cuts
• Conforms to DIN 352 for reliable interchangeability
• Suitable for unalloyed and alloyed steels up to 800 N/mm², cast iron, and non-ferrous metals

In daily use

This tap set is intended for manual thread cutting in through holes or blind holes. The rougher tap removes most material, the second tap refines the thread, and the finisher tap brings it to final size. The bright finish reduces friction and helps clear chips. The square drive accommodates a standard tap wrench.
