Carmex Carbide Threading Insert - NPTF, TiAlN Coated, 30-8NPTF is a durable carbide insert designed for precise, long-lasting threading across a wide range of profiles. Built for machinists and shops that demand reliable performance in both internal and external threads, it delivers consistent results with minimal tool changes.

• Length options: Five lengths spanning 12–40 mm to fit diverse threading tasks and depths.
• Pitch range: Handles pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), covering the most common and fine-thread applications.
• TiAlN coating: Enhances hardness and heat resistance for extended tool life in demanding materials and high-heat machining.
• Double-edged design: Two cutting edges per insert (except for BSPT, NPT, NPTF, American Buttress, API RD) to maximize usable life.
• Internal & External capability: For many thread profiles, the same insert can machine both internal and external threads, reducing the need for multiple tools.
• Wide thread-profile coverage: Part of Carmex’s versatile threading insert family that supports the majority of common thread standards.

Ideal for precision hydraulic and pneumatic fittings, fasteners, and general metalworking where consistent thread quality matters. The TiAlN coating helps maintain accurate thread profiles over longer runs, while the double-edge design provides dependable edge life. With five length options and broad profile compatibility, this insert offers flexible, reliable performance for everyday threading tasks in CNC and manual machining environments.
