Meet the Carmex Carbide Threading Insert, TiAlN coated and tailored for NPSM threading. Model 30I8NPSM delivers dependable performance for machinists and shops that need versatile, long-lasting inserts across common thread profiles.

• Varied lengths: 5 lengths from 12 mm to 40 mm to fit a wide range of thread depths and applications.
• Pitch range: Capable of handling pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) for both fine and coarse thread work.
• TiAlN coating: TiAlN coating enhances wear resistance and heat tolerance, extending insert life in demanding materials and ongoing production runs.
• Double‑sided cutting edges: Two cutting edges per insert (except for BSPT/NPT/NPTF/American Buttress/API RD) for better tool life and reduced downtime.
• Internal/External capability: For many thread profiles, the same insert can machine both internal and external threads, simplifying tooling (exceptions: ISO/UN/NPSM/UNJ/Acme).

The design emphasizes practical versatility: one insert can cover a broad spectrum of standard threads, helping you reduce tool inventory while maintaining consistent thread quality. The TiAlN coating and dual edges support longer tooling life in production environments, so you can complete more parts per shift with fewer tool changes. Use cases range from hydraulic fittings to precision machine components where reliable threading across multiple profiles matters.
