FLUTELESS TAPS FOR THREAD ROLLING MACHINES

 


 

Fluteless taps produce threads by deforming the material, thus without any chips. They are suitable for blind and through holes, and their field of application has grown wider, including now aluminum, steel and stainless.


Outlook & Drawing

Fluteless Taps for Non-ferrous Alloys IT Partvanadium-containing high-speed steel with nitride coating


Fluteless Taps for Non-ferrous Alloys IT Part



Application of the Forming Tap

Suitable for cooper, brass, bronze, aluminum alloy and zinc casting

Tool Material Type: Vanadium-containing High-Speed Steel (HSSE)

Surface treatment: N (Nitride)


Features

  • Achieves high-quality, burr-less tapping and controlling the minor diameter geometry of internal thread
  • For IT industry, the thread size is below M3
  • Wider tapping application range with the ability for high speed tapping
  • Quite fit for aluminum alloy casting and zinc casting application


Attention! Threading with fluteless tap is only applicable for stringy materials
