Why choose it

The TiAlN coating provides high hardness and oxidation resistance, allowing higher cutting speeds and dry machining. Form B with a 4-5 thread lead chamfer is ideal for through holes, ensuring efficient chip evacuation and clean threads.

Ideal use cases

• Threading M5 coarse threads in through holes
• Production machining of steels up to 1000 N/mm²
• Working with stainless steels and cast iron
• Non-ferrous metal applications

Good to know

Use with a recommended core hole diameter of 4.2 mm. The tap conforms to DIN 371 for machine taps with reinforced shank.
