Introducing the Carmex Carbide Threading Insert, Unified, TiAlN Coated — model 40E8UN. This versatile carbide insert is designed for machinists and job shops tackling a wide range of Unified thread profiles with reliable, repeatable results.

• Model: 40E8UN — Unified threading insert built for consistent performance across common thread standards.
• Material: Carbide insert with a TiAlN coating for enhanced hardness, heat resistance, and wear life at higher cutting speeds.
• Thread profile coverage: Covers all common thread profiles, making it a practical choice for varied threading tasks.
• Length options: Five lengths available, from 12 mm up to 40 mm, to suit different depth requirements and workpiece geometries.
• Pitch range: Depending on length, supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), enabling a broad range of thread sizes.
• Cutting edges: Double-sided design with two cutting edges per insert (except for BSPT, NPT, NPTF, American Buttress, and API RD variants).
• Internal/External capability: For many thread profiles, the same insert can machine both internal and external threads (with exceptions for ISO, UN, NPSM, UNJ, and Acme).

This insert is engineered to streamline threading workflows: the TiAlN coating reduces wear and heat buildup, allowing higher-speed operation without sacrificing edge life. Its double-edged design means you get more usable life from each insert, while the broad pitch and profile coverage minimizes the need for multiple tool holders and inserts. Ideal for professional shops that prioritize reliability, consistency, and flexibility across a range of Unified thread applications.
