Description

The Carmex Carbide Threading Insert – NPS, TiAlN Coated is a versatile, high-performance solution built for professional machinists who produce a wide range of thread profiles. With multiple length options and broad pitch compatibility, it delivers reliable threading results across common applications.

  • Five length options: available in 12 mm to 40 mm lengths to match different thread depths and profiles.
  • TiAlN coating: provides enhanced wear resistance and heat tolerance for longer insert life and steadier performance in demanding threading operations.
  • Double-sided design: two cutting edges per insert (except for BSPT/NPT/NPTF/American Buttress/API RD), increasing usable life and reducing tool changes.
  • Internal & external threading versatility: in many thread profiles, the same insert can machine both internal and external threads, streamlining your setup (exceptions: ISO/UN/NPSM/UNJ/Acme).
  • Broad pitch range: handles pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), covering the majority of common threading tasks.
  • Comprehensive profile coverage: designed to tackle all common thread profiles with a single, adaptable insert platform.

This carbide threading insert is ideal for job shops, maintenance departments, and machining centers that prioritize versatility, durability, and consistent thread quality. Its dual-edged design and TiAlN coating reduce downtime and wear, while the five-length range and wide pitch compatibility provide flexibility across many projects—without needing a multitude of different inserts. Whether you’re tightening a pipe thread set or finishing a precision mechanical thread, this insert is built to perform reliably.
