THREADING INSERTS

These threading inserts are available in two different lengths (26 mm and 40 mm). Depending on the length – they can handle pitches from 0.5 mm / 20 TPI to 3.0 mm / 8 TPI.

Features:

  • The inserts are double sided, i.e. have two cutting edges (except for BSPT / NPT / NPTF)
  • The inserts for Whitworth / BSPT / NPT / NPTF thread profiles can be used for both internal and external threads

Carbide Grade(s):

Advanced new sub-micron carbide grade with multi-layer PVD coating: Provides high performance under all conditions. The new grade ensures high abrasion resistance, and is capable of machining a wide range of materials, including tough and difficult-to-machine materials, and high alloy steels.
