Machine Nut Tap DIN 357 HSSE - M 4 x 0.7

• Long reduced shank allows several nuts to run over – perfect for serial production
• For through threads and difficult-to-reach areas
• HSSE ensures durability and precision cutting
• For non-abrasive materials up to 800 N/mm²
• Ideal for unalloyed and low-alloyed steels
• Manufactured according to DIN 357 for consistent quality

1. Preparation: Secure the nut, clean the pre-drilled hole, and apply cutting oil.
2. Alignment: Align the tap perfectly perpendicular to the workpiece.
3. Tapping: Apply steady feed and use moderate speed for clean threading.
4. Serial work: Let the finished nut slide over the long shank and continue with the next one.
5. Inspection: Deburr, clean, and check thread quality with a GO/NO-GO gauge.

What makes a machine nut tap special?
Its long reduced shank design allows serial nut tapping – ideal for continuous production and efficient workflow.

What does DIN 357 define?
It defines geometry, dimensions, and tolerances of nut taps used for through threads, ensuring interchangeability and process reliability.

What materials can it cut?
Best suited for non-abrasive materials and steels up to 800 N/mm². Avoid using on hardened steels.

Can I use it manually?
Yes, with a suitable Mũi taro ren tay (tạo ren trong) wrench or a 2.1 mm square drive collet. For precision or volume work, a machine setup is recommended.

Why choose HSSE material?
HSSE offers superior toughness and wear resistance compared to HSS, ensuring long tool life and consistent performance.
