Carmex Carbide Threading Insert - UNJ - TiAlN Coated - 14I18UNJ

Carmex Carbide Threading Insert – UNJ, TiAlN coated, model 14I18UNJ – a durable, versatile threading solution built for professionals who demand reliable performance on lathes and CNC machines.

• Coating & material: TiAlN-coated carbide insert designed to withstand heat and wear for longer tool life during threading operations.
• Length options: Five available lengths (from 12 mm to 40 mm) to fit a wide range of tool holders and setups.
• Pitch range: Broad threading capability from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) for common thread profiles.
• Double-sided edges: Each insert has two cutting edges (except BSPT/NPT/NPTF/American Buttress/API RD) for extended use before reindexing.
• Internal/External capability: For many thread profiles, the same insert can machine both internal and external applications (except ISO/UN/NPSM/UNJ/Acme).

The Carmex 14I18UNJ threading insert is designed to deliver consistent thread forms across a range of standard profiles, helping you minimize tool changes and maintain accuracy on every pass. The TiAlN coating enhances heat resistance for steadier cutting performance, while the multi-length, multi-pitch design provides the flexibility to tackle diverse jobs without carrying multiple dedicated inserts. Keep in mind the profile-specific caveats for ISO, UN, NPSM, UNJ, and Acme when selecting the exact geometry for a given project.
