Designed for UNJ threading, the Carmex Carbide Threading Insert delivers precise, durable performance with a TiAlN coating that stands up to demanding metalworking conditions. It's a versatile solution for machinists who work across common thread profiles and need reliable results with every cut.

• Material and coating: Carbide insert with TiAlN coating for enhanced wear resistance and heat management during threading.
• Thread profiles covered: A versatile collection that covers all common thread profiles.
• Length options: Five lengths available, from 12 mm to 40 mm.
• Double-sided cutting edges: The inserts are double sided, i.e. have two cutting edges (except BSPT / NPT / NPTF / American Buttress / API RD).
• Internal/External threading compatibility: For many thread profiles, the same insert can machine both internal and external applications (except ISO / UN / NPSM / UNJ / Acme).

The design combines two cutting edges per insert with a TiAlN coating for longer life and consistent thread finishes. The five-length range (12 mm–40 mm) helps you match insert size to hole depth and pitch requirements, reducing guesswork in setup and tooling. While many profiles allow the same insert to handle both internal and external threading, be mindful of exceptions such as ISO, UN, NPSM, UNJ, and Acme workloads. This Carmex UNJ threading insert is a practical, dependable choice for job shops and production environments that value repeatable results and efficient setups.
