Why choose it

The HSS construction provides good wear resistance and heat tolerance for general-purpose threading. The straight flute geometry ensures efficient chip evacuation in through holes, reducing the risk of clogging and tap breakage. The DIN 371 standard guarantees compatibility with common tap holders and collets.

Ideal use cases

• Creating M6 threads in through holes
• Maintenance and repair workshops
• General machining on steel, cast iron, and non-ferrous metals
• Production environments requiring consistent thread quality

Good to know

The tap has a bright finish, which provides a clean surface and helps reduce friction during cutting. Always use appropriate cutting fluid for longer tool life and better thread finish.
