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

TiN Coated Fluteless Tap for IT Partsvanadium-containing high-speed steel with titanium nitride coatingTiN Coated Fluteless Tap for IT Parts

Application of Fluteless Tap

Suitable for ferrous materials such as low carbon steels, medium carbon steels, high carbon steels

Tool Material Type

Vanadium-containing High-Speed Steel (HSSE)

Surface treatment

TiN (Titanium 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
