The Carmex Carbide Threading Insert – UNJ, TiAlN coated – 14I14UNJ – is a versatile threading solution designed for precision on lathes and CNC machines. It covers the industry’s most common thread profiles with durability and consistent results across a wide range of parts.

  • Length options: Available in five lengths from 12 mm to 40 mm to fit different machines and engagement requirements.
  • Pitch range: Capable of threading from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), depending on the inserted length, enabling a broad set of standard thread pitches.
  • Coating: TiAlN-coated carbide for enhanced wear resistance and heat tolerance, delivering longer insert life in demanding threading operations.
  • Cutting edges: Double-sided design provides two cutting edges per insert (except for BSPT, NPT, NPTF, American Buttress, and API RD geometries), maximizing usable life between changes.
  • Internal/External versatility: For many thread profiles, one insert can machine both internal and external threads, reducing tool changes—note that some geometries (ISO, UN, NPSM, UNJ, Acme) may require a specific orientation.
  • Material and stability: High-precision carbide construction delivers rigidity and consistent thread forms, even on tougher materials.

Designed for professional workshops that demand reliability and efficiency, this insert delivers steady, accurate threading with fewer tool changes and simpler inventory. The combination of a TiAlN coating, dual cutting edges, and a broad range of lengths and pitches supports a wide variety of parts—from fine, precision screws to larger screw forms—without switching tooling mid-project. Its UNJ designation and broad coverage mean you can tackle many common thread profiles with a single, dependable carbide insert, while keeping within practical geometry considerations for internal versus external threading.
