COLD FORMING FLUTELESS TAPS FOR THREAD ROLLING MACHINES

TiN COATED FLUTELESS TAPS WITH SHORT THREAD

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.

Design and dimensions of the chipless tap

vanadium-containing high-speed steel with titanium nitride coating

Application of Fluteless Tap

Suitable for both ferrous and non-ferrous alloys materials. And it could be used in tapping Machine, Auto Lathe, CNC, etc.

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

Surface treatment: TiN (Titanium Nitride)

Features of the chipless tap

Capable of high-speed cutting and efficient tapping
Offer drastically improved durability
Applicable for use where the tapping length can not be reached with a standard length tap application

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