The Carmex Carbide Threading Insert — Unified — TiAlN Coated — 40I14UN is a versatile, all-in-one threading solution designed to cover the most common thread profiles with a single insert system. Built from carbide and finished with a TiAlN coating, it delivers reliable performance across a range of machining tasks.

• Five length options: Available in five lengths from 12 mm to 40 mm to suit different machines and workpieces, with pitches ranging from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) depending on length.
• Universal coverage: A single insert family designed to machine the majority of common thread profiles, reducing the need for multiple tools.
• Double‑sided cutting edges: Each insert offers two cutting edges for extended life, except for BSPT/NPT/NPTF/American Buttress/API RD profiles.
• Internal & external threading capability: For many thread forms, the same insert can machine both internal and external threads (with exceptions ISO/UN/NPSM/UNJ/Acme).
• TiAlN coating on carbide: The TiAlN coating enhances hardness and heat resistance, helping maintain edge integrity during demanding threading operations.

This unified threading solution helps streamline tool use and production planning by covering a broad range of thread forms and pitches with one robust insert. The dual cutting edges and TiAlN coating work together to improve wear resistance and consistent thread quality, making it suitable for both prototype runs and ongoing production tasks that require reliable performance across multiple profiles.
