The Carmex Carbide Threading Insert - Unified - TiAlN Coated - 30E8UN is a versatile, high-performance cutting insert designed to tackle a wide range of common thread profiles with reliability and consistency. Built for machinists and shops that demand precise threads and long tool life, this TiAlN-coated carbide insert delivers solid results across multiple applications.

• Five length options: available in 12 mm, 16 mm, 20 mm, 30 mm, and 40 mm lengths to fit different tool holders and engagement depths.
• Wide pitch coverage: supports pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), enabling both fine and coarse thread work.
• TiAlN-coated carbide: enhanced wear resistance and heat handling for extended insert life in demanding materials and high-speed machining.
• Double-sided cutting edges: two usable edges on most profiles, maximizing tool life and reducing downtime between indexings (except for BSPT/NPT/NPTF/American Buttress/API RD).
• Internal and external threading capability: for many thread profiles, the same insert machines both internal and external threads, reducing the need for multiple inserts (note: certain profiles such as ISO/UN/NPSM/UNJ/Acme have limitations).
• Unified threading solution: engineered to cover the most common thread standards with a single, reliable insert system, simplifying setup and inventory.

This insert is ideal for precision threading tasks in turning centers and CNC lathes where consistent thread form, clean finishes, and minimal tool changes matter. Its robust carbide composition and TiAlN coating help maintain sharpness through tough materials, while the multiple length options and broad pitch range provide flexibility across various projects. Whether you’re producing tight tolerances on fine-pinished threads or handling larger, deeper threads, the Carmex 30E8UN delivers dependable performance with straightforward, efficient operation.
