The Carmex Carbide Threading Insert for NPTF with TiAlN coating is a versatile, high-precision tool designed for professional machinists who need reliable thread formation across a wide range of profiles.

• Thread profiles covered: A comprehensive collection that spans all common thread profiles, streamlining tooling in one insert family.
• Length options: Five lengths from 12 mm up to 40 mm to suit different depths, reach, and rigidity needs.
• Pitch range: Depending on the chosen length, supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI).
• Double-edged design: Inserts are double-sided with two cutting edges for extended life (note: BSPT/NPT/NPTF, American Buttress, API RD profiles may not utilize both edges).
• Internal/external capability: For many profiles, the same insert can machine both internal and external threads, reducing tool swaps (exceptions include ISO/UN/NPSM/UNJ/Acme).
• Coating: TiAlN coating enhances wear resistance and performance at higher temperatures, helping maintain precision over longer cutting cycles.
• Material: Solid carbide construction delivers rigidity and consistent thread economics across demanding materials.
• NPTF compatibility: Specifically engineered to deliver accurate NPTF thread formation with reliable threading performance.

This insert set is designed to deliver repeatable, accurate threads with fewer tool changes and longer edge life. The TiAlN coating reduces wear in high-temperature cutting, while the broad length and pitch options give you the flexibility to tackle deep pockets, tight tolerances, and a variety of material hardness. Whether you’re building precise fasteners, repairing components, or setting up high-mix production, this insert helps you maintain quality and efficiency with each pass.
