Carmex Carbide Threading Insert – UNJ, TiAlN coated, is engineered for machinists who handle UNJ thread forms and a broad range of common thread profiles. This versatile carbide insert collection aims to reduce tool changes while delivering precise threads across multiple pitches.

• TiAlN Coating: TiAlN-coated carbide insert for enhanced heat resistance and extended cutting life in demanding threading tasks.
• UNJ Threading Capability: Specifically designed for UNJ thread forms, designated 14E24UNJ, to support precise UNJ threading applications.
• Five Length Options: Available in five lengths from 12 mm up to 40 mm, with pitches ranging from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) depending on length.
• Double-Sided Cutting Edges: Each insert offers two cutting edges for increased usable life, with exceptions for BSPT, NPT, NPTF, American Buttress, and API RD profiles.
• Internal/External Capability: For many thread profiles, the same insert can machine both internal and external applications, except for ISO / UN / NPSM / UNJ / Acme profiles.
• Comprehensive Profile Coverage: A versatile collection designed to cover all common thread profiles, streamlining procurement and stock management.

This TiAlN-coated carbide threading insert delivers dependable performance across a wide range of threads, reducing interruptions and improving throughput in CNC and manual machining setups. The combination of multiple lengths, dual cutting edges, and broad profile coverage makes it a practical choice for workshops that handle varied threading tasks—from fine-pitch work to coarser UNJ threads—without switching tooling often. Note the UNJ-specific consideration for internal vs external threading to ensure optimal results on your setup.
