Carmex Carbide Threading Insert - NPSM - TiAlN Coated - 21I14NPSM

The Carmex Carbide Threading Insert, TiAlN coated and designed around the NPSM standard, is a versatile, long-lasting solution for shops that need reliable threading across common profiles. Built for professional use, it combines robust carbide core with a high-performance coating to deliver consistent results.

• Coating & Material: TiAlN-coated carbide insert for enhanced hardness, heat resistance, and extended tool life in demanding threading operations.
• Profile Coverage: Designed to cover all common thread profiles with a single versatile insert system (performance varies by profile; consult guidelines for ISO/UN/NPSM considerations).
• Length Options: Five lengths available, from 12 mm to 40 mm, to suit different holders and pitch requirements.
• Pitch Range: Capable of handling pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), depending on the chosen length.
• Double-Edged Design: Each insert has two cutting edges for extended life and consistent performance (except for BSPT/NPT/NPTF/American Buttress/API RD profiles).
• Internal & External Threading: In many profiles, the same insert can machine both internal and external threads, offering flexibility and reducing tool inventory (note: ISO/UN/NPSM/UNJ/Acme have specific considerations).

Ideal for production environments where quick setup, reliable threading, and long tool life matter most, this Carmex insert helps you tackle NPSM and other common thread profiles with confidence. Use it for pipe fittings, housings, fasteners, and threaded components where precise, clean threads are essential. The combination of multiple length options, a broad pitch range, and a durable TiAlN coating provides a dependable solution that minimizes tool changes and maximizes throughput.
