The Carmex Carbide Threading Insert — Unified, TiAlN-coated (14I28UN) — is a versatile threading solution designed to cover all common thread profiles with a single tooling family. Built for professional shops and machinists, it delivers precise threading across internal and external applications with durable carbide and wear-resistant coating.

• Five length options: Available in 12 mm to 40 mm lengths to suit different depths of cut and hole sizes, enabling broad profile coverage with one insert family.
• Double-sided cutting edges: Each insert provides two cutting edges for extended usable life. Note: BSPT, NPT, NPTF, American Buttress, and API RD profiles are single-edged.
• Internal and external threading support: For many thread forms, the same insert can machine both internal and external threads, reducing tool changes. Exceptions apply for ISO, UN, NPSM, UNJ, and Acme profiles.
• TiAlN coating: TiAlN-coated carbide offers enhanced hardness and wear resistance, helping maintain edge sharpness and finish at higher speeds and tougher materials.
• Unified threading coverage: Designed to handle a wide range of common thread profiles with one insert family, simplifying tooling and inventory management.
• Material: Carbide construction delivers rigidity and thermal stability for consistent, accurate threading results across applications.

This single, versatile insert enables smoother setups, reduces the need for multiple dedicated tools, and supports consistent, high-quality thread production across a variety of materials. The TiAlN coating helps extend insert life in demanding operations, while the dual-edge design provides reliable performance between changes. Ideal for shops that require flexible threading capability without sacrificing precision or efficiency.
