COLD FORMING ROLL TAPS FOR THREAD ROLLING MACHINES
TiN COATED ROLL TAPS FOR IT PARTS
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
Application and Features 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).
- 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
