The Carmex Carbide Threading Insert — Unified, TiAlN coated (14I32UN) is a versatile, double-edged solution designed for professional machinists who need reliable threading across a wide range of profiles with minimal setup.

• Threading versatility: covers all common thread profiles with a single unified insert approach, reducing the need for multiple tools.
• Five available lengths: built to fit various applications, ranging from 12 mm to 40 mm, enabling efficient engagement across different workpieces.
• Wide pitch compatibility: accommodates pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI) depending on length, matching a broad set of machining needs.
• Double-sided cutting edges: two cutting edges per insert (except for BSPT/NPT/NPTF/American Buttress/API RD) to maximize tool life and reduce index changes.
• Internal & external threading capability: in many profiles, the same insert can machine both internal and external threads, improving efficiency (note: some profiles like ISO/UN/NPSM/UNJ/Acme have exceptions).
• Carbide with TiAlN coating: delivers durability and heat resistance for higher-speed threading and longer service life in demanding materials.
• Brand and accuracy you can trust: Carmex precision tooling designed for consistent thread quality and repeatable results.

This insert is ideal for production shops, job shops, and maintenance environments where threaded components are routine. Use it to tackle a wide spectrum of common thread profiles with fewer tool changes, maintain tight tolerances, and achieve clean, accurate threads on both internal bores and external shafts. Its carbide substrate paired with TiAlN coating supports higher cutting speeds and extended tool life, helping you complete more parts per shift with dependable results.
