The Carmex Carbide Threading Insert (UNJ) with TiAlN coating is a versatile threading solution designed for machinists who need reliable performance across common thread profiles. Built for durability and consistency, it supports a range of internal and external threading tasks where applicable.

• Five length options: Available in 12 mm to 40 mm lengths, providing the right reach and rigidity for different workpieces and depths of cut.
• Double-sided cutting edges: Each insert has two cutting edges for extended tool life and fewer index changes (except for BSPT / NPT / NPTF / American Buttress / API RD).
• TiAlN-coated carbide: The TiAlN coating reduces wear and extends insert life in demanding threading applications.
• Wide pitch compatibility: Depending on length, it can handle pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI).
• Internal/External threading versatility: For many thread profiles, the same insert can machine both internal and external applications, with exceptions for ISO / UN / NPSM / UNJ / Acme profiles.
• UNJ threading insert code: Designed as part of the UNJ family to address common UNJ threading tasks with reliable performance.

This insert blends robust carbide construction with a protective TiAlN finish to deliver dependable threading performance across a variety of projects. Its multi-length lineup and dual cutting edges help streamline setups, while the broad pitch range supports a wide array of thread specifications. Ideal for precision machining shops and fabrication environments that value consistency, efficiency, and tool longevity.
