Meet the Carmex Carbide Threading Insert for NPT — a durable, TiAlN-coated solution built for precise NPT threading in production and job‑shop environments. Designed for professionals who work with internal and external threads, this insert delivers reliable performance with focused, dedicated geometry for NPT applications.

• Material & Coating: Carbide insert with TiAlN coating for exceptional wear resistance and heat tolerance in demanding threading tasks.
• NPT-focused design: Specifically configured for NPT thread profiles, offering reliable cutting performance on standard NPT workpieces.
• Cutting Edge Configuration: Single cutting edge (in contrast to the double‑sided convention for many profiles), optimized for NPT geometry and consistent chip control.
• Length Options: Five lengths available, spanning from 12 mm to 40 mm to fit different depths and tooling setups.
• Pitch Range Compatibility: Capable of handling pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI) depending on the chosen length.
• Internal/External Capability (where applicable): For many thread profiles, the same insert can machine both internal and external threads, reducing tool inventory (note: certain profiles such as ISO, UN, NPSM, UNJ, and Acme may have unique considerations).

This NPT insert is part of a versatile Carmex family that covers all common thread profiles, enabling streamlined setups and fewer tool changes. The TiAlN coating helps extend insert life in tough materials and high-temperature cutting, while the single-edge design for NPT provides consistent performance and predictable results across a range of thread depths and diameters. Ideal for CNC operators, machine shops, and manufacturing environments where reliability, precision, and efficiency matter.
