The Carmex Carbide Threading Insert, TiAlN-coated and designed for NPSM threading, offers a versatile solution for machinists who need reliable, multi-profile threading capability from a single insert.

• Length options: Available in 5 lengths ranging from 12 mm to 40 mm to fit different tools and applications.
• Pitch range supported: Handles pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), covering the most common threading needs.
• Two cutting edges (double-sided): Each insert provides two cutting edges to extend life and reduce tool changes (except for BSPT/NPT/NPTF/American Buttress/API RD).
• Internal/External threading versatility: For many thread profiles, the same insert can machine both internal and external threads (with exceptions such as ISO/UN/NPSM/UNJ/Acme).
• Coating and material: Carbide substrate with TiAlN coating delivers hardness, wear resistance, and better heat tolerance for demanding materials.
• Part code: 14E18NPSM confirms readiness for NPSM threading and related profiles.

This insert is ideal for toolrooms and production environments where minimizing setup time and tool changes matters. The TiAlN coating helps preserve edge life on hard metals, while the broad length and pitch options enable quick adaptation to different thread geometries without carrying multiple dedicated inserts. Whether you’re finishing threads on a CNC lathe or performing internal and external threading on the same setup, this Carmex insert delivers consistent performance and reliable results.
