Direct supplies tooling for metal processing from Taiwan
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

Long Thread Fluteless Tap for Steels vanadium-containing high-speed steel with Homo ProcessingLong Thread Fluteless Tap for Steels

Application of Fluteless Tap

Suitable for low cabon steel, medium cabon steel and high cabon steel.

Tool Material Type

Vanadium-containing High-Speed Steel (HSSE)

Surface treatment

Homo Processing

Features

  • High efficiency and longer tool life
  • No chip formation and save chip disposal time
  • Reduced danger of breakage through rigid design
  • For the production of threads in through and blind holes
  • Produce an excellent pitch diameter well within the class of fit the pitch diameter tolerances
  • Ideally suited for long thread application
