The Carmex Carbide Threading Insert - Unified - TiAlN Coated - 40E14UN is a versatile, high-precision solution for threading tasks on lathes and mill-turn centers. Built for shops that routinely produce unified and common thread profiles, it delivers dependable performance across internal and external applications.

• Thread profiles covered: A unified collection that supports all common thread profiles with five lengths (12 mm to 40 mm), handling pitches from 0.5 mm / 32 TPI to 6.0 mm / 4 TPI.
• Length options: Five distinct lengths to fit different setups and reach needs, optimizing rigidity and reach for various workpieces.
• Double‑sided cutting edges: Each insert has two cutting edges for extended life and reduced tooling downtime, with exceptions for BSPT/NPT/NPTF/American Buttress/API RD profiles.
• Unified internal/external capability: For many thread profiles, the same insert can machine both internal and external threads (except ISO / UN / NPSM / UNJ / Acme).
• Coating and material: TiAlN-coated carbide inserts provide enhanced wear resistance and thermal stability for higher-speed threading on diverse materials.
• Brand and compatibility: Part of Carmex’s threaded turning inserts family, designed to integrate with Carmex threading holders for reliable performance.

Benefits: This approach simplifies setup and inventory while delivering consistent thread accuracy across a wide range of pitches and profiles. The TiAlN coating extends edge life under demanding cutting conditions, helping you maintain productivity at higher speeds. The five-length lineup gives you the right balance of reach and rigidity for everything from fine 0.5 mm threads to coarser 6.0 mm threads, making the 40E14UN a practical choice for job shops, contract manufacturers, and in-house machining environments that tackle unified and UN threading tasks.
