The Carmex Carbide Threading Insert for NPTF with TiAlN coating is a durable, versatile cutting solution crafted for machinists who regularly produce a wide range of common thread profiles, including NPTF. Built for precision and long edge life, it’s designed to perform reliably on both internal and external threading tasks where the profile allows.

• Thread profiles covered: A versatile collection that supports the most common threading standards, enabling you to tackle a variety of jobs with one insert.
• Length options: Five lengths available, ranging from 12 mm to 40 mm, so you can match reach to your workpiece and job requirements.
• Pitch range: Handles pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI) for broad compatibility with standard specifications.
• Double-edged design: Each insert is double-sided to maximize tool life—two cutting edges are available for most profiles (exceptions apply for BSPT, NPT, NPTF, American Buttress, and API RD).
• Internal/External capability: For many thread profiles, the same insert can machine both internal and external threads, reducing tool changes and setup time (exceptions include ISO/UN/NPSM/UNJ/Acme).
• Coating: TiAlN coating enhances hardness and heat resistance, helping maintain cut quality and extend edge life in demanding materials.
• Material: Solid carbide construction delivers consistent performance, rigidity, and wear resistance in metalworking environments.
• Application focus: Optimized for NPTF threads and suitable for a range of general threading tasks on CNC lathes and manual machines.

This insert system is designed to streamline your threading workflow: choose the appropriate length to reach the mating thread, flip or rotate the insert to use the second edge when needed, and rely on the TiAlN coating to resist heat and wear during deeper cuts. Whether you’re producing pipe fittings, hydraulic components, or precision mechanical parts, this Carmex insert helps you achieve consistent thread quality with fewer tool changes and replacements, boosting efficiency in your shop.
