Carmex Carbide Threading Insert - Unified - TiAlN Coated - 14E20UN

The Carmex Carbide Threading Insert – Unified – TiAlN Coated – 14E20UN is a versatile carbide solution designed for machinists who routinely work with a range of thread profiles. Built for durability and precision, it delivers dependable performance across turning and milling applications.

• Universal threading coverage: Designed to handle all common thread profiles within the Unified standard, including the 14E20UN family, minimizing the need for multiple inserts.
• Five length options: Available in 12 mm, 16 mm, 20 mm, 32 mm, and 40 mm lengths to suit different depths of cut and tool setups; the length determines the pitch range you can machine—from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI).
• TiAlN coating: Titanium aluminum nitride coating boosts hardness and wear resistance, helping extend insert life in demanding materials and high-speed operations.
• Double-sided cutting edges: Most inserts provide two cutting edges for extended use, allowing more passes before reindexing. (Exceptions: BSPT / NPT / NPTF / American Buttress / API RD.)
• Internal and external threading capable: In many profiles, the same insert can machine both internal and external threads, reducing tool inventory and setup time. (Note: ISO / UN / NPSM / UNJ / Acme may require specific inserts.)

This insert is ideal for shops seeking a flexible solution that covers a broad spectrum of threading tasks without swapping inserts. It’s well-suited for medium to heavy turning on steel, stainless steel, and other common metals, delivering reliable geometry and wear resistance with every pass.
