COLD FORM 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

Form Taps for Non-Ferrous Alloys with Short Thread vanadium-containing high-speed steel with nitride coating


Form Taps for Non-Ferrous Alloys with Short Thread



Application of Fluteless Tap

Suitable for nonferrous alloys such as cooper, brass, bronze and aluminumand it's alloys

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

Surface treatment: N (Nitride)

Form Tap Features

  • Capable of efficient, long life and high speed tapping
  • No chip formation and save chip disposal time
  • Ideally suited for short thread application

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