The Carmex Carbide Threading Insert for UNJ, TiAlN coated, is a precision tool designed for machinists who need reliable UNJ and related thread forms with durable, long-lasting performance.

• TiAlN coating: TiAlN-coated carbide insert for enhanced wear resistance and higher-temperature capability in tough threading operations.
• Thread profiles: A versatile collection that covers all common thread profiles, simplifying tooling choices for widespread UNJ applications.
• Length options: Five lengths available (12 mm to 40 mm) to match depth and pitch requirements across projects.
• Pitch range: Depending on length, supports pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI for flexible threading capability.
• Double-sided cutting edges: Each insert has two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), maximizing edge life and reducing tool changes.
• Internal/External threading compatibility: For many thread profiles, the same insert can machine both internal and external threads, improving workflow efficiency (with exceptions for ISO / UN / NPSM / UNJ / Acme).

Designed to streamline threading workflows, this UNJ-focused carbide insert set delivers consistent thread quality across a variety of profiles while reducing tool changes and inventory. The TiAlN coating helps sustain performance in demanding materials, and the double-edged design extends usable life between regrinds or replacements. Whether you’re producing precise internal threads or external threads on steel, alloy, or similar workpieces, these inserts offer dependable, versatile performance for everyday machining needs.
