Introducing the Carmex Carbide Threading Insert – Unified, TiAlN Coated, model 40E16UN. This versatile, high-precision insert is designed for machinists who need reliable threading across the most common Unified profiles.

• Thread profile coverage: Unified threading capability that supports a wide range of common thread forms with a single insert.
• Length options: Five lengths available, from 12 mm up to 40 mm, to match different threading needs.
• Pitch range: Depending on the length, it can handle pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI).
• Coating: TiAlN coating for enhanced wear resistance and heat tolerance, promoting longer tool life and stable cutting performance.
• Material: Carbide insert designed for durability and precision in threading operations.
• Double-sided design: Two cutting edges per insert (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), increasing usable life per piece.
• Internal/External versatility: For many thread profiles, the same insert can machine both internal and external threads (with exceptions for ISO/UN/NPSM/UNJ/Acme).

This single, well-rounded threading solution helps you cover most standard jobs with fewer tool changes, delivering consistent results and reliable performance across a range of unified thread applications. The combination of multi-length options, dual cutting edges, and a robust TiAlN-coated carbide body makes it a practical choice for shops aiming to improve throughput and reduce tooling costs on threaded components.
