The Carmex Carbide Threading Insert is a TiAlN-coated carbide insert designed for reliable, precise threading across a wide range of profiles. It’s built for machinists and shops that need a versatile, durable solution for both internal and external threads.

• Length options: Five versions spanning 12 mm to 40 mm to fit different toolholding and engagement needs.
• Thread profiles covered: A versatile collection that addresses all common thread profiles in a single, adaptable insert set.
• Double-sided cutting edges: Each insert provides two cutting edges for extended usable life (except BSPT/NPT/NPTF/American Buttress/API RD).
• Internal/External capability: For many profiles, the same insert can machine both internal and external threads, reducing tool inventory (except ISO/UN/NPSM/UNJ/Acme).
• Coating: TiAlN coating enhances wear resistance and heat tolerance for longer service life in demanding materials.
• Material: Sturdy carbide substrate delivers rigidity and consistent thread geometry during precision threading operations.

This insert pairings a broad thread-profile reach with durable construction, helping you reduce tool changes, maintain consistent thread quality, and complete jobs—from prototyping to production runs—with fewer tooling interruptions.
