Carmex Carbide Threading Insert - NPSM - TiAlN Coated - 14I18NPSM

Carmex Carbide Threading Insert for NPSM, TiAlN coated, is a versatile, durable choice for machinists who work with a variety of thread profiles. Designed to handle internal and external threading tasks with reliability, it’s built to streamline setups in metalworking shops and job sites.

• Threading range and profiles: Covers all common thread profiles with pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), depending on the chosen length.
• Five length options: Available in 12 mm to 40 mm lengths to suit different machining needs and access limitations.
• Double‑sided cutting edges: Each insert provides two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD standards), maximizing usable life per insert.
• Internal and external threading capability: In many profiles, the same insert can machine both internal and external threads, reducing the need for multiple tools (note: some ISO/UN/NPSM/UNJ/Acme profiles may differ).
• TiAlN coating on carbide: The TiAlN coating enhances wear resistance and heat tolerance, helping to maintain tolerance and finish in demanding threading operations.
• Wide applicability: A robust solution for general threading needs across a range of materials and machine setups, suitable for professional workshops and production environments.

This carbide threading insert is ideal for shops that require flexible tooling to cover multiple thread standards without frequent tool changes. Use it for both precision fittings and customer parts where reliable thread quality and consistent finish matter. The TiAlN coating supports longer tool life in high-temperature cutting, while the double‑sided design provides value by extending usable edges per tool. Whether you’re tackling pipe threads, coaxing clean internal threads, or matching external fasteners to mating parts, this insert is built to deliver dependable results with minimal setup downtime.
