CHIPLESS TAPS FOR THREAD ROLLING MACHINES

CHIPLESS TAPS FOR STEEL 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.

Outlook & Drawing метчика-раскатника

vanadium-containing high-speed steel with Homo Processing

Application of the Fluteless Tap

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

Surface treatment: Homo Processing

Features of the Tap

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 short thread application

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