The Carmex Carbide Threading Insert for UNJ threads is a TiAlN-coated carbide solution designed to deliver precise, reliable threading across a wide range of common profiles. Built for machinists and production environments, this insert family offers versatility and durability in a single, interchangeable tool.

• Thread profiles: A versatile collection that covers all common thread profiles with a single insert family.
• Lengths: Five length options ranging from 12 mm to 40 mm to match different pitch requirements.
• Pitch range: Depending on the length, suitable for pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI).
• Cutting edges: Double-sided design with two cutting edges for most profiles, extending tool life (exceptions apply for BSPT/NPT/NPTF/American Buttress/API RD).
• Internal/External capability: For many thread profiles, the same insert can machine both internal and external applications (except ISO/UN/NPSM/UNJ/Acme).
• Coating: TiAlN-coated carbide for improved wear resistance and heat tolerance, helping maintain precision under demanding cutting conditions.
• Substrate: Carbide insert designed for enduring performance and long tool life in threading operations.

Designed to reduce tool changes and inventory while maintaining consistent thread quality, this UNJ-compatible insert delivers dependable results across varied materials and pitches. The TiAlN coating helps manage heat during deeper or faster passes, while the dual-cutting-edge design provides the option to index for a fresh edge without swapping inserts. Ideal for job shops and high--output setups that require flexible threading capability without compromising accuracy.
