TiN Coated Rolling Taps with Long Threadvanadium-containing high-speed steel with titanium nitride coating

TiN Coated Rolling Taps with Long Thread

Application of TiN coated rolling taps with long thread

Suitable for both steel and non-ferrous alloys. 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).

TiN coated rolling taps features

  • 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
