The Carmex Carbide Threading Insert – Unified – TiAlN Coated (40I10UN) is a versatile, durable solution for precision threading across the most common thread forms. Designed for machinists and production shops that value reliability and flexibility, this insert handles a wide range of UN-style threads with a single, robust tool.

• Coating: TiAlN-coated carbide for improved wear resistance and higher temperature stability, extending insert life in challenging cutting conditions.
• Length options: Five lengths available, from 12 mm to 40 mm, to suit shallow pockets and deeper cuts alike.
• Pitch range: Depending on length, supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) for broad threading coverage.
• Double-sided cutting edges: Each insert provides two cutting edges for extended tool life (note: BSPT/NPT/NPTF/American Buttress/API RD are exceptions).
• Internal/External capability: For many thread profiles, the same insert can machine both internal and external threads, reducing tool changes and inventory needs (with some profile exceptions).
• Thread type: Unified (UN) threading compatibility with the 40I10UN designation, suitable for standard machine shop workflows.
• Material: Solid carbide construction delivers rigidity, repeatability, and consistent thread quality across runs.

This insert is ideal for job shops and contract manufacturers aiming to simplify tooling, maximize throughput, and achieve predictable thread quality on a variety of materials. Its TiAlN coating and dual-edge design provide dependable performance, while the range of lengths and pitches ensures you can dial in the exact geometry needed for your UN-threading tasks without swapping inserts.
