The Carmex Unified TiAlN-coated carbide threading insert (14I9UN) is a versatile solution for machinists tackling a wide range of thread profiles. Built for both internal and external threading tasks, it delivers reliable performance with multiple cutting edges and a robust coating to extend life.

• Coating: TiAlN coating enhances wear resistance and heat tolerance for longer insert life.
• Material: Carbide construction provides stiffness and precision for consistent thread quality.
• Double-Sided Edges: Two cutting edges per insert extend productive life (except for BSPT / NPT / NPTF / American Buttress / API RD).
• Length Options: Five lengths available from 12 mm to 40 mm to suit different threading tasks.
• Pitch Range: Handles pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) for broad compatibility with common standards.
• Internal/External Flexibility: In many profiles, the same insert can machine both internal and external threads (except ISO / UN / NPSM / UNJ / Acme).
• Comprehensive Coverage: A unified collection that covers all common thread profiles, reducing the need to switch between multiple inserts.

The combination of TiAlN-coated carbide and a double-edged design delivers precise, repeatable results across a wide range of threading tasks. The five length options let you optimize depth of cut and engagement for different pitches, while the broad profile coverage helps streamline tool selection in busy shop environments. By minimizing tool changes and simplifying inventory, this insert supports efficient production and consistent thread quality on countless applications.
